How to read these numbers
These numbers show you the battery’s raw capability and how it will fit into your system. You’ll want to match continuous and peak current needs of your motor/controller and ensure the charger fits your recharging habits.
Battery chemistry and capacity
You’ll benefit from LiFePO4 chemistry, which gives stable voltage, high cycle life, and better thermal stability than many other lithium types. With 100Ah capacity at 48V, you get approximately 5120Wh — a big step up from equivalently sized lead-acid banks in usable energy and lifespan.
Why LiFePO4 matters
You’ll notice LiFePO4 runs cooler, resists thermal runaway, and handles deeper discharges without severe capacity loss. That means you can routinely use 80% depth of discharge and still expect long service life — about 5000 cycles to 80% DOD as specified.
Real usable energy
You’ll realistically use close to the full 5120Wh if you manage DOD sensibly. Compared to lead-acid, which is usually limited to 30–50% recommended discharge, you’ll get more usable energy per cycle and a lower total cost of ownership over time.
Built-in BMS and Bluetooth monitoring
You’ll appreciate the built-in 200A BMS that manages cell balancing, over/under voltage protection, overcurrent protection, and temperature protection. The Bluetooth monitoring and LCD let you check voltage, state of charge (SOC), temperature, and charge status in real time from your phone or on the unit.
What the Bluetooth app gives you
You’ll be able to view SOC, individual cell voltages (depending on app detail), battery temperature, and charge/discharge current on iOS/Android devices. This makes it easy to confirm system health, track usage patterns, and catch issues before they become critical.
Why balancing and protections matter
You’ll avoid premature degradation when the BMS keeps cells balanced during charging and discharging. The BMS protects your investment by cutting off in unsafe conditions and allowing the battery to operate within safe limits for longer life.
Peak current and performance
You’ll be impressed by the advertised 1000A peak current for 3–5 seconds. LOSSIGY’s design allows the 200A smart BMS to provide an exceptional short-term peak that meets the startup and high-load demands of most golf cart controllers and motors.
How peak current helps you
You’ll experience strong acceleration and reliable motor starts because the battery can supply the inrush current motors or controllers demand for a few seconds. This peak capability bridges the gap between continuous rating and transient loads that occur in real driving.
Continuous power limits
You’ll want to respect the 200A continuous limit of the BMS for steady loads. The continuous rating is what determines how long the battery can support sustained high power; the peak current helps with short bursts only. Match your motor and inverter behavior to these limits to avoid unnecessary shutdowns.
Charging and the included 18A charger
You’ll get an 18A lithium charger with the battery, which simplifies replacement and ensures the battery receives an appropriate charge profile for LiFePO4 chemistry. Typical full recharge times will depend on how depleted the battery is and whether you’re using a single charger or charging multiple parallel batteries.
Estimated charging times
If you’re charging from near-empty to full with the included 18A charger, you’ll need roughly 100Ah / 18A = ~5.5–6 hours under ideal conditions, plus a small margin for charger tapering. If you want faster charging, you can use a higher-current charger rated for LiFePO4, but confirm compatibility and BMS limits first.
Charger settings and compatibility
You’ll want to use chargers that support LiFePO4 profiles or have adjustable float/absorb settings compatible with LiFePO4 voltage points. The built-in BMS will manage charging within safe limits, but a properly configured charger will optimize battery life and charge speed.
Installation and compatibility
You’ll find the battery easier to install and move than a comparable lead-acid bank because it’s self-contained, single-box design. That makes it especially convenient for golf carts, motorhomes, solar energy storage, and many industrial devices that use 48V systems.
Physical installation tips
You’ll want to secure the battery in a dry, ventilated location and connect it using the correct gauge cable and properly rated fuses or circuit breakers. Keep battery terminals clean and torque connections to manufacturer specs to avoid heating and voltage drop.
Electrical compatibility
You’ll match the battery to a 48V system and ensure the motor controller and inverter can accept the battery’s continuous and peak currents. If your controller demands more than the continuous 200A, the short-term peak can help, but you risk triggering BMS limits if sustained draws exceed 200A for long periods.
Real-world performance expectations
You’ll get significant runtime improvements over lead-acid batteries for the same weight and footprint. If you’re running a typical golf cart motor or a 48V inverter for appliances, your usable runtime will depend on load, motor efficiency, and terrain or application specifics.
Example runtime scenarios
If you’re using the battery to run a 48V motor that consumes 800W on average, you’ll get roughly 5120Wh / 800W ≈ 6.4 hours of operation under ideal conditions. If you’re driving a golf cart with higher intermittent power demands, real-world runtime will vary based on acceleration, load, and terrain.
Inverter and motor support
You’ll be able to support a 3000W inverter for over an hour under moderate conditions according to manufacturer guidance, but exact duration depends on the load profile. Continuous heavy loads will approach the battery’s continuous discharge capability faster than intermittent loads do.
Safety and thermal management
You’ll benefit from LiFePO4’s inherently stable chemistry and the BMS protections that reduce the risk of thermal runaway and other dangerous conditions. That said, you should still follow safe handling and charging routines to minimize risk.
BMS safety functions
You’ll have overcurrent protection, short-circuit protection, over-temperature and under-temperature protections, and cell balancing functions built into the 200A BMS. This set of protections will actively prevent damage in many common fault scenarios.
Environmental considerations
You’ll want to avoid charging or discharging in extreme temperatures outside the battery’s recommended operating range. If you use the battery in very cold or very hot climates, keep it in a temperature-controlled compartment or use temperature-based charging cutoffs if available.
Lifespan and maintenance
You’ll see a much longer usable lifespan compared with lead-acid; the specified ~5000 cycles to 80% DOD translates to many years of daily use for most users. With minimal maintenance — mainly keeping terminals clean and ensuring firmware/app updates if applicable — the battery will outlast traditional alternatives.
Calendar life and cycle life
You’ll likely get several years of service even with daily use given the high cycle rating. Calendar life will depend on operating temperature and charge patterns, so avoid prolonged storage at high state-of-charge and high temps to preserve longevity.
Maintenance tasks
You’ll perform occasional inspections for corrosion and tightness, and you’ll monitor cell balance and health via Bluetooth to catch any developing issues early. You won’t have to perform watering or equalization like lead-acid batteries, which simplifies upkeep considerably.

- You’ll be limited by the included 18A charger if you need fast recharges between heavy usage periods; upgrading the charger is possible but requires care.
- You’ll want to follow proper safety and charging protocols — LiFePO4 is safer than many chemistries but still needs correct management and protection.
Who should buy this
You’ll see this battery as a strong fit if you’re converting a golf cart from lead-acid to LiFePO4, building a mobile power solution for an RV, or need a robust 48V battery for solar storage or light industrial equipment. If you prioritize long life, monitoring, and high startup current capability, this package aligns well with those priorities.
Who might want a different option
You’ll want to look elsewhere if your system regularly demands sustained currents well above 200A for long periods and you can’t add parallel capacity. You’ll also consider alternatives if you need faster recharge cycles than the included 18A charger can provide without modification.
How to install and use
You’ll find the installation straightforward if you follow basic electrical safety and manufacturer instructions. Below are practical steps to help you get started and avoid common mistakes.
Basic installation steps
- You’ll ensure the system is powered down and isolated before you begin any wiring or mechanical work.
- You’ll physically mount the battery in a secure, level location with adequate ventilation and protection from road spray if used in vehicles.
- You’ll connect the battery positive and negative with appropriately sized cables and install a properly rated fuse or DC breaker close to the battery positive terminal.
- You’ll verify terminal torque and secure mounting before powering the system and checking the Bluetooth/LCD readout to confirm health and SOC.
Parallel installation considerations
You’ll only parallel batteries of identical type, age, and state-of-charge to avoid imbalance and uneven current sharing. If you want to connect up to 4 batteries in parallel, you’ll wire them evenly and use busbars or equal-length cables to minimize voltage differences between units.
Charging best practices
You’ll extend battery life and maintain safety by charging with a LiFePO4-compatible charger and by avoiding prolonged exposure to full charge at high temperatures. The included 18A charger works well for overnight recharges, but you should set up charging schedules and monitor via Bluetooth where possible.
Recommended charge profile
You’ll use a charge profile that tops out at LiFePO4 recommended voltages (typically around 3.6–3.65V per cell, or ~58V for a 48V pack depending on BMS specifics). You’ll avoid float voltages designed for lead-acid that could overcharge LiFePO4 cells over long periods.
Storage and standby charging
You’ll store the battery at a partial state of charge (around 40–60%) if you expect long-term storage, and you’ll check the SOC periodically. You’ll avoid storing fully charged at high temperatures, as that accelerates calendar aging.
Troubleshooting common issues
You’ll run into occasional hiccups with any battery system, but many issues are simple to diagnose and correct using the Bluetooth app and LCD readout. Here are common problems and practical steps you can take.
Battery won’t power the system
You’ll first check fuses, breakers, and cable connections for continuity and correct polarity. You’ll then confirm the BMS isn’t in protective cutoff mode by checking the LCD and app for fault codes; if a fault is present, follow the app guidance or contact support.
Unexpected shutdowns or BMS cutoffs
You’ll look for high-temperature warnings, low-voltage cutoffs, or overcurrent events as possible causes. You’ll reduce load and allow the battery to cool or recharge, and then investigate whether load demands exceed the continuous capability or if a wiring/connection issue is causing voltage drop.
App or Bluetooth connection issues
You’ll make sure your phone’s Bluetooth is on and that the battery’s app is allowed to access connectivity. You’ll move your phone closer to the battery and ensure no other Bluetooth devices are interfering; if problems persist, try restarting the app or power-cycling the battery (per manufacturer instructions).
Comparing to lead-acid and other lithium options
You’ll find LiFePO4 offers significant advantages over lead-acid in usable energy, weight, cycle life, and maintenance. Compared to other lithium chemistries, LiFePO4 trades slightly lower energy density for much better thermal stability and cycle life.
Lead-acid vs LiFePO4
You’ll typically get 3–5 times the cycle life and 2–3 times the usable energy from LiFePO4 vs lead-acid of the same nominal capacity. You’ll enjoy lower total cost of ownership, less maintenance, and lighter weight when you switch.
LiFePO4 vs NMC or other lithium chemistries
You’ll get safer thermal characteristics and higher cycle life with LiFePO4, but you’ll give up some energy density compared with NMC cells. For vehicle and stationary applications where safety and longevity are priorities, LiFePO4 is often the best practical choice.
Tips for parallel expansion
You’ll be able to expand capacity by connecting up to four batteries in parallel, but certain practices will help you avoid imbalance and premature wear. Follow equal-length cable practices, ensure all batteries are at similar SOC when connecting, and use a single charging source where possible to keep balance consistent.
Practical parallel setup rules
You’ll always parallel identical batteries: same model, same age, same firmware revision if applicable. You’ll avoid mixing brands or capacities, and you’ll ensure the BMS parameters are consistent across units to prevent one unit from overworking.
Monitoring and balancing in parallel banks
You’ll use the Bluetooth app to check each unit’s status when possible, and you’ll periodically check voltages under load and charge to ensure even distribution. If imbalance occurs over time, you’ll want to cycle and rebalance or consult manufacturer support for recommended procedures.
Warranty, support and service
You’ll get an initial 90-day worry-free after-sales window and 24-hour online technical support from LOSSIGY, which makes it easy to get help quickly if you run into problems. For longer-term warranty specifics, you’ll check the vendor or LOSSIGY documentation and register your product as instructed.
Getting support
You’ll contact LOSSIGY’s support channels for technical questions, fault codes, or warranty claims. You’ll keep purchase documents and serial numbers handy to speed up the service process and to verify coverage.
What to expect from service interactions
You’ll typically receive troubleshooting guidance, firmware updates (if available), and replacement procedures if a verified defect is found under warranty. You’ll follow their instructions for shipping or returning a unit if needed and keep copies of all correspondence.

Frequently asked questions (FAQ)
You’ll often have specific practical questions before buying; here are direct answers to common concerns to help you decide confidently.
How long will a full charge take with the included 18A charger?
You’ll typically expect around 5.5–6 hours to charge from near-empty to full with a single 18A charger, plus extra time for tapering. If you often need shorter turnaround times, you’ll consider a higher-current charger but confirm BMS compatibility first.
Can I use this battery in my golf cart without modifications?
You’ll usually be able to swap this battery into most 48V golf carts without major changes, but you’ll verify connector compatibility, cable sizing, and controller current limits. If your cart regularly draws more than 200A continuous, you’ll assess whether parallel batteries or controller adjustments are needed.
Is it safe to leave the battery connected while the cart is unused?
You’ll want to follow manufacturer guidance: LiFePO4 can be left connected, but you’ll monitor SOC and avoid extended storage at 100% SOC or in high temperatures. If you expect long-term storage, you’ll bring the battery to a recommended partial SOC and check it periodically.
What happens when peak current is exceeded?
You’ll trigger the BMS protections if continuous or excessive currents exceed thresholds, and the battery may cut off or limit output to protect cells. You’ll resolve by reducing load, checking wiring and connections, and ensuring the battery is within its operating temperature range.
Can I parallel different capacity batteries?
You’ll avoid paralleling batteries of different capacities, chemistries, or ages because you’ll create imbalance and possible premature failure. You’ll stick to identical units for parallel expansion.
If you’d like, you can tell me the specific motor/controller or inverter you’ll pair with this battery and I’ll help you size whether a single unit or a parallel bank is the best fit for your needs.
