Key Specifications

Below is a clear breakdown of the main specs you’ll want to know before buying or installing this kit. This table summarizes voltages, capacity, discharge limits, and included accessories so you can compare it to your current system or other options.

This table gives you the quick facts you’ll refer to when measuring runtime, charger compatibility, and whether your golf cart controller or inverter can cope with the outputs.

Clarifying usable energy and DOD

The pack’s nominal energy is 5.12 kWh per unit (51.2V × 100Ah). The marketing also cites 5,000+ cycles at 80% Depth of Discharge (DOD). If you adhere to 80% DOD, each battery provides about 4.096 kWh usable (5.12 kWh × 0.8). The kit’s statement about 20.48 kWh usable for 4 parallel units likely assumes using the full nominal capacity; you should confirm with the seller whether “usable” refers to total nominal energy or recommended DOD-based usable energy.

You should ask the vendor to clarify whether their usable energy number is nominal or recommended-DOD-based before sizing systems for critical loads.

Performance & Real-World Use

You’ll appreciate how the battery behaves under load, how long it will run your equipment, and how the BMS protects the pack. This section translates specs into practical runtime estimates and performance behavior you’ll notice day-to-day.

Real-world runtime depends mostly on your average load. Use the simple formula: Runtime (hours) = Usable energy (Wh) ÷ Average load (W). If you use 80% DOD for longevity, plan on about 4,096 Wh usable per battery.

Example runtime calculations

• If your golf cart draws 1,200W on average during use, a single battery at 80% DOD will run it roughly 4,096 ÷ 1,200 ≈ 3.4 hours.
• At a continuous 2,000W draw, runtime drops to about 2.0 hours.
• For a heavy draw scenario (e.g., powerful cart, hills, or towing) averaging 4,000W, expect around 1.0 hour from a single unit at 80% DOD.

These practical examples help you estimate how many parallel units you’ll need for your typical usage.

Peak power handling and brief bursts

The pack is rated for 200A continuous, which equals about 10.24 kW at nominal voltage — more than enough for most golf carts and many vehicle conversions. The 600A, 3-second burst is useful for acceleration or short inrush demands but shouldn’t replace a sustained higher-capacity system.

You’ll want to avoid repeated or sustained bursts near the short-burst limit because thermal stress and BMS limits will constrain continuous reliability.

Power Output & Discharge Characteristics

This battery is designed to satisfy high current demands, which matters if your cart has a powerful motor or you run steep courses. The continuous 200A discharge covers most OEM controllers, and the short 600A burst handles heavy accelerations.

You’ll find performance consistent across charge cycles because LiFePO4 chemistry maintains voltage stability under load compared with lead-acid options.

How voltage behaves under load

LiFePO4 remains relatively flat across most of its state-of-charge compared to lead-acid, which means you’ll feel more consistent speed and torque as the battery discharges. That stability is a big reason LiFePO4 performs well in vehicles where motor behavior is tied directly to battery voltage.

You’ll notice less sag under moderate loads and better recovery after bursts, thanks to the pack’s internal resistance characteristics and BMS protections.

Cycle Life & Longevity

With premium A-grade LiFePO4 cells and a smart BMS, this pack claims 5,000+ cycles at 80% DOD — that’s a decade or more of heavy use for many users. That cycle life is the main reason you might prefer LiFePO4 over lead-acid despite higher upfront cost.

If you keep DOD lower (e.g., 50%), life will typically extend well beyond 5,000 cycles. The built-in BMS plays a key role by protecting against conditions that would otherwise shorten cell life.

What that cycle life means for costs

You’ll pay more up-front compared with lead-acid, but when you divide cost by usable cycles, LiFePO4 often ends up cheaper per kWh delivered over the battery’s life. Fewer replacements, less maintenance, and higher usable capacity per pack make it cost-effective over time.

You should run the math for your usage patterns: estimate annual kWh usage and compare total cost of ownership across years to validate the investment.

Installation & Setup

You’re getting an all-in-one kit, but installation still needs care. This section helps you plan the physical swap, charger hookup, and monitor setup so your system is safe and reliable.

Before you begin, measure your battery compartment and check mounting points, cable access, and ventilated space. If the battery dimensions or weight affect cart handling, you should plan accordingly.

Step-by-step installation guidance

1. Power down and isolate the vehicle: disconnect any charging source and remove the ignition key.
2. Remove old batteries safely: follow manufacturer guidance for acid batteries if you’re replacing lead-acid. Wear gloves and eye protection.
3. Inspect battery bay: clean corrosion, check tray integrity and ensure a flat mount surface.
4. Fit the LiFePO4 pack: secure with the supplied retention strap or a mounting bracket that prevents movement.
5. Connect the pack: use heavy-gauge cables rated for the BMS continuous current; connect the positive first and the negative last when making final connections.
6. Install the LCD display: mount the 2.8-inch touch display where you can see charge state and alarms.
7. Pair the Bluetooth app: follow the manufacturer’s app pairing steps to monitor parameters and configure alerts.
8. Connect and test the charger: plug in the 58.4V 18A charger and verify correct charging behavior (BMS should allow charging and the LCD should show charge progress).
9. Test under light load: run the cart without passengers to confirm voltage behavior, controller compatibility, and that there are no error codes.

Following these steps reduces the chance of electrical mistakes and ensures the BMS and charger communicate properly.

Wiring considerations and fuses

Use cable gauges appropriate for the BMS rating — typically 1/0 AWG or similar for currents up to 200A depending on run length. Place an appropriate main fuse or circuit breaker close to the battery positive terminal. The fuse should protect cabling and match the system’s safe interrupt capacity.

You should also use tight, clean connections and consider bus bars for parallel systems to equalize wiring lengths and reduce imbalance risk.

Wiring Best Practices & Safety

Electrical safety isn’t optional. Proper wiring prevents damage and protects you from hazards. The BMS offers many protections, but your wiring must match the battery’s capabilities.

You’ll want to avoid undersized conductors, loose terminals, and long runs that increase voltage drop. Keep cable runs short and symmetrical when paralleling multiple batteries.

Fusing strategy and parallel connection tips

• Fuse each battery’s positive terminal close to the pack when paralleling.
• Use identical cable lengths and connector types across parallel units to balance current sharing.
• When paralleling, install the packs at the same state-of-charge. The BMS can handle some imbalance, but large SOC differences stress both packs.
• If you remove or add packs later, re-evaluate bus connections and re-balance if recommended by the manufacturer.

These practices protect both batteries and downstream electronics and prolong pack life.

Charger, BMS, App & Monitoring

You’ll like that the kit includes a 58.4V 18A charger sized specifically for LiFePO4 chemistry. A charger matched to the pack’s recommended float and max charge voltage helps the BMS and cells remain healthy.

The BMS is Bluetooth-enabled and provides protections against overcharge, over-discharge, short circuit, and extreme temperatures. The combination of on-pack LCD and remote app means you can check state-of-charge, cell balancing status, voltage and current, and BMS alarms before you head out.

How the charger and BMS work together

The charger supplies a 58.4V maximum charge target for a full LiFePO4 charge (3.65V per cell for a 16s pack). The BMS will allow charging but can cut off if it detects over-voltage, cell imbalance, or temperature beyond safe thresholds. During charging the BMS also balances cells when necessary.

You should let the charger complete its taper cycle rather than unplugging mid-charge frequently — the charger’s taper accounts for internal balancing and ensures cells reach the same voltage.

App features you’ll use

• Real-time SOC and voltage monitoring.
• Alarm notifications for temperature or voltage extremes.
• Historical charts (depending on app) for seeing charge/discharge cycles and trends.
• Potential BMS configuration options (check which settings are accessible via the app).

You’ll appreciate being able to diagnose issues remotely and keep an eye on the battery during long storage periods or remote use.

Compatibility & Use Cases

This battery is marketed primarily for golf carts, but you’ll also find it suitable for RV conversions, home energy storage (small systems), and off-grid applications. The high discharge capability and parallel scalability broaden its utility.

You should check whether your cart’s controller, wiring, and onboard electronics are rated for the pack’s maximum charge voltage (I.e., 58.4V fully charged) and continuous discharge demands.

Use case examples

• Golf carts: Single pack often replaces a full 48V lead-acid bank and provides more run time, faster recharge, and lower maintenance.
• RV auxiliary power: One pack can run DC loads, inverters, or be part of a multi-pack system for more capacity.
• Solar/charge controllers: Works as a storage bank for small off-grid setups; supports parallel expansion to increase kWh.
• Light EV conversions: High current capability supports sporty acceleration for small EV projects.

These examples show you how flexible the pack can be when matched correctly to the rest of your system.

Troubleshooting & Maintenance

You’ll rarely need extensive maintenance, but knowing typical issues and fixes saves time and avoids downtime.

Common troubleshooting tips:

• If the pack won’t charge, check charger connections, charger output with a meter, and BMS fault indications in the app or LCD.
• If you see voltage sag or BMS cut-outs under load, verify cable gauges, terminal tightness, and whether the BMS is limiting current due to temperature or cell imbalance.
• If Bluetooth or the LCD fails to show expected data, reboot the app or power cycle the pack and ensure firmware is up to date if the manufacturer provides updates.

Regular maintenance actions you should perform:

• Inspect cable terminations periodically and tighten to spec.
• Keep terminals clean and corrosion-free.
• Check for firmware updates for the BMS app if provided.
• Store the battery at a roughly 40–60% SOC for longer-term storage unless the manufacturer specifies otherwise.

These practices keep the battery healthy and reduce the chance of unexpected failures.

Common alarm causes and what to do

• Over-temperature: Allow cooling or move the pack to a cooler environment before retrying.
• Over-voltage during charging: Confirm charger settings and BMS configuration; use the supplied charger or a verified replacement.
• Under-voltage cut-off: Recharge immediately; repeated deep discharges reduce cycle life.
• Cell imbalance: Balance cycle through charging or seek manufacturer guidance if imbalance persists.

You’ll find the app and LCD provide early alerts so you can take corrective steps before damage occurs.

Frequently Asked Questions

Here are answers to common questions you’ll likely have when considering or installing this battery.

Q: Is this a direct drop-in replacement for my lead-acid 48V bank? A: Often yes, electrically the nominal voltage is compatible, but you must confirm physical fit, terminal compatibility, and that your cart’s charger or controller tolerates the LiFePO4 pack’s full charge voltage (58.4V). Also ensure battery mounts and harnesses are secure.

Q: How long will the included charger take to fully charge a depleted 100Ah battery? A: The 58.4V 18A charger provides roughly 1.05 kW. The theoretical charge duration from 0–100% is about 100Ah ÷ 18A ≈ 5.6 hours, but accounting for charge taper and inefficiencies, plan for about 6–7 hours. From 20–80% (typical top-up), expect proportionally less time.

Q: Can I mix this battery with other battery brands or older batteries in parallel? A: Don’t mix different chemistries or different-age batteries. If you parallel multiple units, use identical packs, same state-of-charge at connection, and identical cabling to ensure equal current sharing. Mixing increases the risk of imbalance and reduces lifespan.

Q: What maintenance does LiFePO4 require compared to lead-acid? A: Much less. No watering, minimal equalization, and lower self-discharge. You still need to inspect connections, keep firmware updated, and avoid extreme temperature exposure.

Q: Do I need to change the speed controller or wiring in my golf cart? A: Usually no, if the controller is rated for 48V nominal and can tolerate the 58.4V full charge voltage. However, verify your controller’s voltage ratings and consult a specialist if unsure.

Q: Are there special temperature considerations? A: Yes. LiFePO4 does not tolerate charging below certain temperatures without a heater or specific BMS logic. The BMS should protect against charging at low temperatures, but confirm the manufacturer’s specified operating range for charging and discharging.

These FAQs address the most common concerns you’ll have when assessing the swap.
