Compatibility and fit
You can expect broad compatibility with most modern golf cart brands and models up to 4000W. If you own a Club Car, EZGO, ICON, or Yamaha cart, the battery should integrate without major wiring changes. For street-legal 48V carts (≤25 mph) and many small off-grid applications, the pack will fit and function well.
What to check before buying
Double-check the physical mounting space, terminal orientation, and your controller’s maximum currents so you know the 200A continuous/600A peak BMS suits your motor/controller setup. If you plan to parallel multiple packs, verify that you have adequate room and cable management for the added batteries.
Performance and power delivery
The 200A continuous BMS means reliable, sustained power for high-draw situations like acceleration, hills, and towing. You’ll notice stronger, more consistent acceleration compared to lead-acid batteries, and the 600A peak helps with brief power surges.
How the power specs translate to real-world use
The battery’s nominal energy is 51.2V × 100Ah = 5,120 Wh (5.12 kWh). The BMS supports continuous outputs up to 200A, which at 51.2V equals about 10.24 kW peak capability on paper (200A × 51.2V = 10,240W). That’s enough to support most 5kW motors comfortably and handle short bursts required by steeper inclines or quick acceleration.
Range estimation and energy use
To estimate range, you’ll calculate energy consumption of your cart in Wh per mile. If your cart consumes 400 Wh/mile, the battery’s 5.12 kWh nominal capacity would give roughly 12.8 miles (5,120 Wh ÷ 400 Wh/mile = 12.8 miles). If your cart is more efficient and uses 250 Wh/mile, expect about 20.5 miles. Use your actual motor load and driving profile to refine these numbers.
Charging time and charger behavior
The included 51.2V, 18A charger delivers about 921.6W to the battery (51.2V × 18A). From fully depleted, expect nominal charge time around 5.5 to 6.5 hours, allowing for charging inefficiencies and tapering near full charge. If you rarely fully deplete the pack, top-up charging will be shorter.
Battery management system (BMS) features
LiTime’s self-developed BMS offers advanced protections: over/under voltage, overcurrent, short-circuit, cell balancing, and thermal management. The smart BMS is responsible for the 200A continuous/600A peak discharge rating, and it manages parallel configurations automatically when you link multiple packs.
Real-time monitoring and control
You can connect an external display via RS485 to monitor voltage, current, SOC, cell voltages, temperature, protection status, and parallel connection state. The display also lets you remotely shut off or control discharge for safety and diagnostics. That visibility helps you manage usage and spot issues early.
Safety and reliability
LiFePO4 chemistry is among the safest lithium options due to thermal stability and robust chemistry. Combined with the integrated smart BMS and a physical ON/OFF switch, you’ll have both software and hardware layers of safety for maintenance and emergency situations.
Built-in ON/OFF switch and emergency shutoff
The dedicated power switch gives you a mechanical way to isolate the battery instantly. This is useful during maintenance, storage, or if you need to quickly disconnect the system in an emergency or to prevent parasitic drain.
Physical installation and mounting
The kit’s custom bracket simplifies mounting in many carts, and the included hardware reduces guesswork. You’ll still need to ensure correct terminal orientation and secure cable routing to avoid chafing or accidental disconnection.
Step-by-step installation notes
- Confirm fitment and clearance in the battery compartment.
- Secure the mounting bracket and seat the battery tightly to prevent vibration.
- Connect the charge/discharge leads per the manual, paying attention to polarity and torque specs.
- Install the RS485 display and test communication before road testing.
- Perform a controlled test drive to ensure the controller and motor respond normally.
Parallel expansion and system scalability
You can connect up to eight packs in parallel to expand to 51.2V and 800Ah (40.96 kWh). This option is handy if you need longer range or want to run heavier loads offshore or for extended off-grid use.
Practical implications of parallel setups
Parallel expansion increases runtime linearly but requires careful balancing, identical pack states on connection, and proper cabling. With eight packs you’ll also need space and heavier gauge cabling, plus attention to BMS communications if you plan remote monitoring of each pack.
Lifecycle, longevity, and total cost of ownership
LiFePO4 cells are rated for a very high cycle life—manufacturer claims up to 15,000 cycles and a 10-year durability figure. Practically, even conservative estimates (2,000–5,000 cycles) beat lead-acid by a wide margin. Over the lifespan, you’ll likely save up to 80% of life-cycle costs versus lead-acid, when accounting for replacements, maintenance, and energy performance.
What that means for your wallet
Because the pack is lighter, requires no watering, and holds charge longer with less voltage sag, your day-to-day maintenance drops dramatically. The upfront cost is higher than lead-acid, but savings in replacement batteries, operational downtime, and fuel-equivalent energy make it financially attractive over time.
Environmental benefits
LiFePO4 batteries have no heavy metals like lead and are recyclable, which cuts down pollution and disposal concerns tied to lead-acid. If reducing environmental impact matters to you, switching to LiFePO4 is a tangible step.
Comparisons: LiTime LiFePO4 vs lead-acid
You should see much better energy density, less weight, smaller footprint, and longer usable life with LiFePO4. You’ll also enjoy better performance under load and faster acceleration with less voltage sag.

|---|---|---|
| Energy density | High (3–5× lead-acid) | Low |
| Weight | ~25–35% lighter | Heavier |
| Size | ~25% smaller | Larger |
| Cycle life | Up to 15,000 cycles (manufacturer) | ~200–1,000 cycles |
| Maintenance | Minimal | Regular watering, equalization |
| Cost over life | Lower (80% savings claim) | Higher replacement costs |
| Environmental impact | Recyclable, low pollution | Contains lead, disposal issues |
Charger specifics and behavior
The included charger is a smart 51.2V 18A unit designed specifically for LiFePO4 chemistry. It communicates with the BMS during charging to ensure correct charge profile, cell balancing, and a safe end-of-charge process.
Charge cycle tips
Charge in a cool, dry place and avoid charging from very low temperatures without a battery heater or warm environment. Avoid leaving the battery at full charge for months; if storing, keep it around 50–60% SOC for best longevity.
Temperature and operating range
The BMS monitors temperature and will protect the pack from extreme conditions. You should avoid prolonged operation in temperatures well below 0°C without active heating, and in very high ambient temps, give attention to ventilation and heat dissipation.
Practical use cases and scenarios
You can use this battery for daily golf cart runs, converting a 48V street-legal cart, powering small outboard boats, or supplementing home off-grid needs. Its flexibility makes it suitable for both leisure and practical utility tasks where a 51.2V bus is appropriate.
Example scenarios with calculations
- Urban cart, light load: If your cart pulls 250 Wh/mile, expect around 20 miles per full charge.
- Heavy use with hills/towing: If consumption rises to 500 Wh/mile, expect about 10 miles per charge.
- Parallel 4-pack setup (51.2V 400Ah): You’d have ~20.48 kWh, roughly 40–80 miles depending on load and terrain.
Safety best practices
Always disconnect the ON/OFF switch before doing major work, use insulated tools around battery terminals, and route cables with grommets and protective sleeving. Follow manufacturer torque specs on terminals to prevent loose connections and arcing.
Troubleshooting common issues
If the display shows unexpected voltage imbalance, check individual pack connections and RS485 comms. If charging stalls, confirm charger output and BMS fault status. For persistent BMS error codes, contact support with the monitor logs for the quickest diagnosis.
RS485 display: what you’ll see and why it matters
The RS485 display provides SOC, voltage, current, cell-level status, temperature, and protection alerts. Having these readouts lets you react to thermal or voltage anomalies early and gives you confidence when paralleling multiple packs.
Shipping and packing notes
Orders may be split into multiple packages based on size constraints, so parts of your kit could arrive on different days. Plan your installation schedule accordingly and verify package contents against the packing list when everything arrives.
Maintenance and care
Your maintenance needs are minimal: keep terminals clean, ensure the ON/OFF switch functions smoothly, and check the display for warnings occasionally. Periodic cleaning of the battery compartment and ensuring good ventilation will help longevity.
Warranty and support considerations
Check the specific warranty length and coverage terms with the seller, since LiTime’s long cycle claims are impressive but require proper use and follow-up if you need replacements or repairs. Keep purchase and serial records for warranty claims.
