Note on energy: the product lists 5.12 kWh, while nominal voltage times nominal capacity gives 4.8 kWh (48V × 100Ah = 4,800 Wh). The difference can come from different nominal voltage definitions, marketing rounding, or the manufacturer quoting usable energy. Always verify usable kWh with the seller.
Performance and real-world output
You should expect strong performance for high-draw tasks thanks to the built-in 200A BMS and the high peak current claim. In real-world applications, continuous output will generally be limited by the BMS rating while short bursts for acceleration or motor startup will be handled by the battery’s peak capability.
Continuous vs. peak power
The internal 200A BMS defines a safe continuous discharge limit — roughly 9.6 kW at 48V — which is what you can count on for steady loads. The 1000A peak rating is for very short bursts (seconds) to handle motor start currents and other transient demands, but it’s not a long-term continuous power rating.
Expected runtime examples
Runtime depends on how much power your load draws. If your golf cart consumes an average of 2 kW while driving, a 4.8 kWh battery (nominal) would theoretically supply about 2.4 hours of run time before reaching full discharge; in practice, you’ll have losses and you’ll rarely run to 0%, so expect less. For heavy loads near the 200A continuous limit, runtime will be much shorter — power draw of 9.6 kW would deplete the nominal battery in roughly 30 minutes.
Battery chemistry and longevity
The product states “lithium technology” and claims superior energy density and longer cycle life compared to traditional batteries. Most deep-cycle 48V lithium batteries nowadays use LiFePO4 (LFP) cells for safety and longevity, but you should confirm the exact cell chemistry from the manufacturer or seller.
Cycle life expectations
If the battery uses LiFePO4 cells, you can typically expect several thousand cycles at moderate depth of discharge — often in the range of 2,000–5,000 cycles to 80% capacity, depending on how you use it. If the chemistry is different (e.g., NMC), cycle life can vary; checking the datasheet for rated cycles at a specific DoD is important for long-term planning.
Temperature and storage effects
Lithium batteries are sensitive to extreme temperatures: cold reduces available capacity and charging ability, while high temperatures accelerate degradation. Store and charge the battery within the temperature limits the manufacturer specifies. For LiFePO4, safe operating windows are typically wider and less prone to thermal runaway than some other lithium chemistries.
Built-in BMS and safety features
A built-in 200A BMS provides crucial protections like over/under-voltage cutoff, overcurrent protection, short-circuit protection, cell balancing, and temperature protections. The BMS will manage charging and discharging behaviors that keep the pack healthy and safe over time.
How the 200A BMS protects your battery
The BMS monitors cell voltages and pack current, preventing overcharge and over-discharge conditions that would otherwise shorten battery life or create hazards. If current exceeds safe thresholds or a cell goes outside safe voltage or temperature ranges, the BMS will disconnect outputs or limit charging until conditions return to normal.
Peak 1000A current: what it really means
A 1000A peak rating indicates the battery can handle short bursts of very high current, useful for motor starting or regenerative braking spikes. It’s important to treat that number as a short-duration capability — the BMS’s continuous 200A rating is the more relevant figure for sustained loads.
Charging, chargers, and compatibility
You’ll need a charger compatible with 48V lithium batteries and one that respects whatever charge profile the battery requires. If the pack is LiFePO4, the charger voltage and charge termination behavior differ from lead-acid, so use a lithium-compatible charger or a programmable charger set to the battery’s recommended profile.
Recommended charging voltages and currents
For many 48V LiFePO4 packs, full-charge voltage is typically around 54.4–54.6V (3.4–3.65V per cell for 15-cell series packs), but you should follow the manufacturer’s recommended charge voltage and maximum charge current. Charging at the BMS-rated current or lower (e.g., C/2 to 1C depending on spec) is safe; for 100Ah, 1C would be 100A, but the BMS may limit charge to 200A or lower.
Solar and inverter compatibility
This battery is suitable for off-grid solar and inverter systems that operate at 48V, but you should configure your MPPT charge controller or inverter/charger for lithium chemistry (set correct charge voltage, charge stages, and depth-of-discharge behavior). Bluetooth connectivity can help you monitor state of charge, voltage, and health when integrated with an app.
Installing in a golf cart
This battery is marketed specifically for golf cart use, and the 48V nominal rating makes it a natural fit for carts originally designed for 48V lead-acid banks. Swapping to a single 48V lithium module simplifies wiring compared to multi-battery lead-acid banks.
Mechanical fit and connectors
Physical dimensions and terminal placement vary between manufacturers, so measure your cart’s battery bay and note mounting points before ordering. You’ll likely need to adapt or replace hold-downs and possibly terminal connectors; ensure the battery’s terminals match your cart’s cables or plan to install suitable adapters.
Electrical considerations
When switching from lead-acid to lithium, check that motor controllers, chargers, and any onboard electronics either support lithium voltages or can be adjusted. Some chargers intended for lead-acid batteries will not charge lithium properly. Also, ensure the cart’s chargers and controllers won’t get confused by the battery’s internal BMS behavior during balancing or protective disconnects.
Use cases beyond golf carts
You can use this battery in multiple 48V contexts where high capacity and high burst currents are valuable.
Solar energy storage
The battery is well-suited for 48V solar systems where you want high usable capacity and long cycle life; Bluetooth monitoring simplifies checking state-of-charge remotely. Configure your solar charge controller for lithium settings to take advantage of the battery’s full capacity.
Small electric vehicles and scooters
For small EVs that need strong start-up current and sustained power, this battery provides the torque bursts often required by motor controllers. Verify physical fit and that the vehicle’s controller is compatible with the battery’s discharge characteristics.
Marine and RV applications
You can use the pack for marine trolling motors, RV house banks, or auxiliary systems where compact, high-energy batteries are desirable. Watch for exposure to moisture and vibration — proper installation and secure mounting are essential.
Backup power and UPS
If you want a 48V battery bank for inverters and UPS systems, this is a scalable and maintenance-friendly option. Ensure your inverter is set up for lithium chemistry and the BMS is compatible with the inverter’s low-voltage cutoffs.
Maintenance and care
One of the benefits of modern lithium batteries is lower maintenance compared to flooded lead-acid cells — no watering, no equalizing, and generally less frequent attention required. Still, a bit of scheduled care will extend the life and reliability of your pack.
Storage tips
Store the battery at partial charge (typically 30–60%) in a cool, dry place if you won’t use it for weeks or months. Avoid storing fully discharged or fully charged for extended periods, and keep the battery within the manufacturer’s temperature and state-of-charge recommendations.
Routine checks
Periodically inspect terminals for tightness and corrosion, ensure mounting hardware is secure, and check Bluetooth or BMS logs for any error warnings. Look for any abnormal heat during use, and pay attention to any unexpected capacity loss over time.
Troubleshooting common issues
If you encounter problems, most issues can be resolved by checking installation and monitoring BMS messages via Bluetooth or the app.
- Battery won’t charge: Confirm charger type and settings; many lead-acid chargers won’t fully charge a lithium pack. Check that the BMS hasn’t entered a protective disconnect due to low voltage or temperature.
- BMS trips on heavy load: You may be pulling more current than the continuous BMS rating allows; reduce sustained load or consider parallel modules if higher sustained output is required.
- Reduced range/performance: Check state-of-health via Bluetooth logs, confirm cells are balanced, and verify that temperature extremes aren’t limiting available capacity.
Comparison to lead-acid and other lithium options
Understanding how this battery stacks up will help you decide if it’s the right investment.
Compared to lead-acid
You’ll get much more usable capacity with lithium, lower weight, faster charging, and far less maintenance than with lead-acid. Upfront cost is higher, but total cost of ownership typically favors lithium over several years due to longer cycle life and higher efficiency.
Compared to other lithium packs
Not all lithium packs are equal: chemistry, BMS quality, and cell brand affect longevity and safety. If the pack uses quality LFP cells and a reliable BMS, it’s a strong choice; cheaper packs may skimp on cell quality or BMS features, which can shorten service life.
Sizing and system design tips
Choosing the right battery is more than matching voltage and Ah — you’ll want to match the battery’s capabilities to your load profile.
- Calculate your typical and peak power needs: average power determines energy capacity required; peak current requirements determine whether the 200A BMS and 1000A peak rating are sufficient.
- Allow headroom: don’t regularly pull right at the continuous BMS limit if you want long life.
- Match charging equipment: ensure your charger, MPPT, or inverter/charger supports the battery’s voltage and chemistry.
Safety considerations
Always observe standard safety practices: use proper fusing on output cables, secure the battery to prevent movement, and avoid short circuits. Because the battery can deliver high currents, correct cable sizes and connections are critical to avoid overheating.
Cable and fuse sizing
Use appropriately sized wiring for continuous currents near the BMS rating; undersized cables can overheat and introduce risk. Install a fuse or DC breaker sized to protect wiring and the battery, ideally below the maximum short-circuit rating of the battery.
Thermal management
Avoid placing the battery near heat sources, and allow ventilation if it’s in a confined space. If you use the battery in a high-temperature environment, expect reduced cycle life.
