LiFePO4 Golf Cart Battery model S51105L is a 48V 200Ah lithium iron phosphate battery engineered for electric golf carts requiring extended range and rapid recharge. Featuring UL1973-certified cells and IP67 waterproof casing, it delivers 5,000+ cycles at 80% depth-of-discharge. Built with integrated BMS for cell balancing and thermal protection, it replaces lead-acid systems with 60% weight reduction. Compatible with Club Car and EZGO models.

What makes S51105L unique among golf cart batteries?
The S51105L stands out with its modular rack-mount design allowing capacity expansion from 200Ah to 600Ah through parallel connections. Its military-grade aluminum housing resists corrosion in humid environments, while adaptive BMS auto-adjusts charging parameters based on temperature (-20°C to 60°C operational range).
Beyond basic specifications, the S51105L utilizes prismatic LiFePO4 cells with 0.2C self-discharge monthly—50% lower than cylindrical alternatives. Pro Tip: Always enable Bluetooth monitoring via the Batrium Watchdog module (sold separately) to track cell voltage divergence in real-time during deep discharges. For example, Florida golf courses using these batteries report 35% longer daily operational ranges compared to AGM setups. Why settle for passive balancing when active current-shunting BMS maintains ±25mV cell variance?
What safety certifications does S51105L hold?
The S51105L meets UN38.3 transport standards and FCC Part 15B for electromagnetic compliance. Its multi-layered protection includes ISO 26262 ASIL-C rated BMS with fail-safe relays isolating cells during overcurrent events (>250A continuous cut-off).
Practically speaking, the battery undergoes nail penetration and thermal shock testing per IEC 62619. Unlike cheaper alternatives, it maintains structural integrity at 8kPa crush loads. Pro Tip: When storing carts for winter, maintain SOC between 40-60% to prevent lithium plating—a common issue when lead-acid practices are misapplied. Consider how Tesla’s Powerwall uses similar LiFePO4 safeguards: multi-stage disconnect protocols that prioritize cell longevity over momentary power demands.

| Feature | S51105L | Lead-Acid Equivalent |
|---|---|---|
| Cycle Life (@80% DoD) | 5,000+ | 500-800 |
| Recharge Time | 3.5hrs (0.3C rate) | 8-10hrs |
How does temperature affect S51105L performance?
The battery operates optimally between -20°C to 55°C with automatic heating pads activating below 0°C. High-temperature throttling reduces max current by 1% per °C above 45°C to prevent electrolyte decomposition.
Interestingly, the S51105L’s nickel-plated copper busbars minimize resistance fluctuations during thermal expansion. Pro Tip: In desert climates, position batteries away from motor compartments—each 10°C rise above 30°C accelerates capacity fade by 0.5%/cycle. Arizona golf resorts mitigate this by installing heat-reflective wraps and scheduling fast charging during cooler morning hours. Remember, LiFePO4’s flat voltage curve means traditional voltage-based SOC estimation isn’t reliable—always use coulomb counting.
What charging system is compatible?
Use 58.4V LiFePO4-specific chargers with CAN bus communication for staged charging. The S51105L supports 120A max charge current (0.6C) using compatible units like the Lester Summit II 650W series.
Transitioning from lead-acid? The S51105L’s BMS negotiates charge profiles through PWM signaling—never apply equalization voltages above 58.4V. For context, a 36-hole golf course using 10 parallel S51105Ls recharges fleets in 90 minutes during peak operations. But what happens if you use a conventional charger? Expect BMS lockouts after 3 invalid handshake attempts, requiring manual reset via the service port.
| Parameter | S51105L | AGM |
|---|---|---|
| Energy Density (Wh/L) | 320 | 80 |
| Peak Efficiency | 98% | 85% |
Can S51105L integrate with existing golf cart electronics?
Yes, through its J1939 CAN bus interface providing SOC, SOH, and fault code transmission. Adapter harnesses convert DE-9 connectors to Club Car’s 48V Precedent systems without controller modifications.
However, carts with resistive throttle systems (pre-2010 models) may require a 48V-12V buck converter for accessory power—direct connections risk BMS overcurrent triggers. Pro Tip: When retrofitting Yamaha Drive carts, disable regen braking until BMS firmware verifies compatibility. Minnesota’s Wild Marsh Golf Club achieved full integration by daisy-chaining three S51105Ls through Anderson SB175 connectors, doubling their fleet’s hill-climbing torque.

48V 200Ah LiFePO4 Golf Cart Battery (Long Size)
FAQs
Yes, but requires MPPT controllers programmed for LiFePO4 voltage limits (absorption: 56.8V, float: 54V). Off-grid setups should include a 48V DC circuit breaker rated ≥150A.
What’s the warranty period?
Redway provides 5-year full replacement coverage—unmatched in the industry—with prorated support extending to 8 years for capacity retention above 70%.
