Battery basics and design
This battery is a 51.2V nominal LiFePO4 pack composed of high-efficiency Grade A cells — not low-cost storage cells. The nominal voltage and the included charger show that the pack is built on a 16-series cell architecture (16 x 3.2V nominal ≈ 51.2V).
The ABS casing offers protection against rust and corrosion and helps shield the pack from splashes and the outdoor conditions golf carts typically see. The pack is designed specifically as a drop-in replacement for common golf cart brands like EZGO, Club Car, and Yamaha — meaning the voltage and discharge profile match what those carts expect.
Electrical capacity and usable energy
Your battery’s rated 100Ah at 51.2V gives you about 5,120 Wh (5.12 kWh) of stored energy. That’s your starting point for estimating run times and how many accessories you can operate simultaneously.
Because LiFePO4 chemistry is stable and the pack is coupled to a 200A BMS, you get a 2C continuous discharge capability (2 × 100Ah = 200A). That 200A continuous current and the calculated 10.24 kW max power (51.2V × 200A) matches the BMS rating and provides the headroom many electric golf carts need for acceleration and hills.
Performance in real-world terms
You’ll notice a few practical benefits immediately: more consistent voltage under load compared with lead-acid, faster acceleration on the first throttle, and more predictable performance late in a round. The BMS maintains safe operation while allowing the pack to deliver strong discharge currents.
Below is a practical runtime table that shows how long the pack will power carts or accessories at different continuous power draws. These estimates assume the pack’s full usable energy is available; in real life you should leave a safety margin to preserve long-term health.
| Continuous Load (W) | Approx. Current at 51.2V | Estimated Runtime (hours) |
|---|---|---|
| 500 W (lights, small accessories) | ~9.8 A | ~10.2 hours |
| 1000 W (small trolling motor, light driving) | ~19.5 A | ~5.1 hours |
| 1500 W (average golf cart motor on mild load) | ~29.3 A | ~3.5 hours |
| 2000 W (heavy driving, incl. hills) | ~39.1 A | ~2.6 hours |
| 3000 W (very heavy continuous load) | ~58.6 A | ~1.7 hours |
These figures are approximations to help you plan. If you drive aggressively or face steep hills, real-world runtime will trend lower. Conversely, gentle use increases runtime.
Charging — speed and behavior
Your kit includes a dedicated 58.4V, 20A fast charger. Because the pack is LiFePO4 and sized 51.2V nominal, the 58.4V charger is appropriate for charging to a full LiFePO4 float/peak voltage (about 3.65V per cell × 16 cells).
Simple math gives you a clear expectation: a 100Ah battery charged at 20A will take roughly 5 hours from near empty to full under ideal conditions (100Ah ÷ 20A = 5 hours). In practice you should add a bit of overhead for tapering at the end of charge, inefficiencies, and any cooling or BMS behavior — expect 5–6 hours from empty to full in normal conditions.
Because the charger is specifically sized for the pack’s chemistry and cell count, you don’t need to worry about mismatched charging voltages or incorrect charge algorithms as long as you use the included charger.
Smart 200A BMS with Bluetooth
The BMS is a core value proposition here. It’s rated for 200A continuous discharge, which matches the pack’s 2C capability and allows the pack to sustain current spikes safely. Because the listed maximum power is 10.24 kW, the BMS is sized for real-world golf cart motor demands.
Key protections you get from the BMS:
- Overcharge protection — prevents cells from being driven beyond safe voltage.
- Over-discharge protection — prevents deep discharge that would damage cells.
- Over-current and short-circuit protection — cuts output instantly on dangerous faults.
- Over-temperature and low-temperature cutoff — keeps charging/discharging safe across weather.
- Bluetooth telemetry — you can monitor real-time voltage, current, temperature, SOC, and alarms on iOS/Android.
With Bluetooth monitoring you can check status remotely and diagnose issues quickly. The touchscreen monitor adds local visual readouts so you don’t have to open the compartment to see what’s happening.
Touchscreen monitoring — what it gives you
The included 2.8-inch LCD touchscreen is small but useful for on-bike or on-cart visibility. It gives you real-time readouts such as state of charge, voltage, current, and possibly temperature depending on the exact interface.
This local interface is helpful during installation and for quick checks without the app. If you prefer phone-based monitoring, the BMS Bluetooth app remains available for deeper telemetry and history.
Durability and lifecycle expectations
One of the biggest advantages of LiFePO4 is long cycle life. This pack claims 6000+ deep discharge cycles. Compared to lead-acid batteries that commonly give several hundred cycles at best, you’re getting a dramatically longer usable life.
Long life means:
- Lower total cost of ownership over years.
- Less frequent replacements and fewer disposal headaches.
- Stable capacity retention over time — LiFePO4 cells lose capacity slowly rather than abruptly.
The low self-discharge rate also helps if you store your cart off-season; the pack will hold a charge far better than lead-acid batteries.
Maintenance and convenience
You don’t have to water LiFePO4 cells, you don’t have to equalize them periodically, and you don’t have to manage multiple 6V or 8V batteries in series if you’re replacing an entire bank. That reduces maintenance time and the chance of human error.
The ABS case helps protect the cells from moisture and rust, and the retention straps let you secure the pack cleanly in the battery bay.
Compatibility and installation notes
This battery is specified for golf carts like EZGO, Club Car, and Yamaha. Here are practical tips for installation and compatibility:
- Physical fit: measure your battery compartment before you order. The kit includes retention straps of about 78.74 inches, enough to secure the pack in many standard bays. Confirm mounting space and terminal clearance.
- Wiring: match battery polarity exactly and use proper gauge cables and torque specs for connections. If you’re replacing multiple old batteries with this single pack, make sure the cart’s wiring and motor controller will accept a single 51.2V source — most modern carts do.
- Fusing and disconnects: ensure you have proper fuses and a disconnect switch as recommended by your cart’s manufacturer and the attachment instructions in the kit.
- Low-temperature charging: the BMS includes low-temperature cutoff to protect cells, but if you operate in sub-freezing conditions consider a battery heater or ensure the pack is not charged below the BMS cutoff temperature.
- Professional help: if you’re not comfortable with battery wiring, use a certified technician to avoid mistakes that could damage equipment or reduce safety.
Practical use cases
You can use this battery as the main propulsion battery for a 48V golf cart, a power source for a trolling motor, or in other 48V accessory applications around the marina, campsite, or yard. Because it’s a 100Ah pack, it suits longer rounds or multiple accessories without rapid depletion.
Example scenarios:
- You run a full day of moderate driving with lights and a stereo — this pack will likely carry you through a full day with margin.
- You use a trolling motor for several hours — the low-discharge and consistent voltage profile benefit trolling motors that prefer steady voltage.
- You convert a golf cart from 6 × 8V lead-acid to one single LiFePO4 pack — reduced weight and simpler wiring are common benefits.
Pros and cons
You should weigh benefits and trade-offs before committing. Here are the main ones in plain language.
Pros:
- Long lifecycle (6000+ cycles), meaning fewer replacements and lower lifetime cost.
- Fast charger included (58.4V, 20A) for relatively quick recharge.
- 200A BMS with Bluetooth gives both protection and telemetry.
- Consistent, high discharge capability (2C) for good acceleration and hill performance.
- Maintenance-free — no watering or equalization required.
- ABS case resists rust and corrosion.
- Full kit includes straps, touchscreen, charger — reduces extra purchases.
Cons:
- Upfront cost will be higher than buying a set of lead-acid batteries (though lifecycle mitigates that).
- If you need more than 200A or extremely high peak currents, check compatibility with your motor/controller.
- Physical dimensions and weight differ from older packs — verify fit first.
- Charging below low-temperature cutoff will be blocked by BMS; you may need a heater or controlled environment in cold climates.
How it compares to lead-acid batteries
Below is a straightforward comparison so you can see the practical differences.
| Feature | 48V(51.2V) 100Ah LiFePO4 | Typical Lead-Acid Bank (equivalent capacity) |
|---|---|---|
| Cycle life | 6000+ cycles | 300–800 cycles |
| Maintenance | Maintenance-free | Regular watering, equalization |
| Self-discharge | Very low | Higher (losses during storage) |
| Usable capacity | Most of rated Ah usable | Often only 50% recommended depth-of-discharge |
| Weight | Typically lighter (depends on lead pack) | Heavier for same usable energy |
| Voltage sag under load | Minimal | Significant |
| Charging time | Faster with proper charger | Slower, requires equalization |
| Safety | Stable chemistry, good thermal profile | Can vent hydrogen during charging |
The short summary: you get far more lifecycle and far less hassle with LiFePO4, and often better performance day-to-day.
Safety and handling tips
You’re working with a high-energy battery. Follow these safety basics:
- Keep terminal tools insulated and avoid accidental short circuits.
- Use proper cable gauges and rated fuses; do not rely on undersized wiring.
- Install in a stable, ventilated area with enough clearance.
- Don’t charge frozen batteries; respect the low-temperature cutoff.
- Follow manufacturer recommendations for torque on terminal hardware.

Troubleshooting common issues
If something doesn’t look right, here are practical checks you can make.
Symptom: Cart won’t start after installation
- Check battery main switch and fuses.
- Verify polarity and that DC connectors are tight.
- Confirm BMS hasn’t entered a protective state (check Bluetooth app or touchscreen).
Symptom: Charger shows error or won’t charge
- Verify charger is the included 58.4V 20A charger and is connected to the correct AC supply.
- Check BMS temperature cutoff — batteries too cold may refuse charge.
- Look for BMS fault codes in the app and follow the recommended reset or service steps in the manual.
Symptom: Unexpected shutdowns under load
- Check BMS log for over-current or over-temperature events.
- Ensure motor controller isn’t demanding peaks beyond the BMS or wiring capacity.
- Verify all cables and connections for heat damage or loose terminals.
If you run into a fault you can’t resolve, contact the manufacturer’s support as described in the warranty section below.
Maintenance schedule
One of the joys of LiFePO4 is reduced maintenance, but you should still keep a short checklist:
- Visual inspection every 3 months — check for loose terminals and secure straps.
- Check Bluetooth app or touchscreen once in a while for abnormal voltages or alarm codes.
- Keep terminals clean and apply anti-corrosion treatment if in a salty environment.
- Store at moderate state of charge (around 40–60%) if you’ll be inactive for months — the low self-discharge makes this simpler than with lead-acid.
Warranty and support
This battery comes with a 5-year warranty backed by SUNHOOPOWER, plus 24/7 customer service for assistance and warranty claims. You should register the product for warranty as recommended and keep purchase records to speed up any claim.
The warranty and continuous support give you peace of mind if a manufacturing defect or early failure occurs.
Who should buy this battery?
You should consider this pack if:
- You want to replace worn lead-acid batteries in a golf cart (EZGO, Club Car, Yamaha) with a single, modern pack.
- You want to cut maintenance — no watering, no equalization, less seasonal attention.
- You value real-time monitoring via Bluetooth and a local touchscreen readout.
- You need reliable performance on hills and during acceleration with a 200A continuous discharge headroom.
