The 48V 100Ah LiFePO4 battery with BMS is a high-performance energy solution optimized for tricycles, golf carts, solar storage, and inverters. Its lithium iron phosphate chemistry ensures long cycle life (3,000–5,000 cycles), thermal stability, and rapid charging via the included 10A charger. The integrated BMS protects against overcharge, overheating, and voltage fluctuations, making it ideal for demanding applications like off-grid solar systems and electric mobility.

Why Is the BMS Critical for 48V Battery Safety?
The Battery Management System (BMS) monitors cell voltages, temperatures, and current flow. It prevents overcharging (above 58.4V), deep discharges (below 40V), and short circuits. For tricycles and scooters, the BMS ensures balanced cell operation, prolonging lifespan and reducing fire risks—a key advantage over non-BMS lead-acid alternatives.
Advanced BMS designs employ multi-layer protection strategies. For example, they use temperature sensors to throttle charging currents if internal heat exceeds 55°C, preventing thermal runaway. The system also performs real-time cell balancing, redistributing energy between cells to maintain voltage uniformity. This is critical in 48V configurations, where 16 LiFePO4 cells work in series. Without balancing, weaker cells could over-discharge, causing irreversible capacity loss. The BMS in this battery utilizes MOSFET transistors for low-resistance disconnects during fault conditions, minimizing voltage spikes that could damage connected devices. This level of protection is particularly vital in solar storage systems, where fluctuating energy inputs from panels require precise voltage regulation.
| Feature | BMS-Protected Battery | Non-BMS Battery |
|---|---|---|
| Overcharge Protection | Automatic cutoff at 58.4V | None |
| Cell Balancing | Active balancing ±20mV | Passive only |
| Temperature Range | -20°C to 60°C | 0°C to 45°C |
How Does the 10A Charger Optimize Recharge Cycles?
The 10A charger replenishes the 4.8kWh battery in ~5 hours, balancing speed with cell longevity. Its CC-CV (constant current-constant voltage) profile avoids stress charging, unlike faster 20A chargers. For solar setups, it complements daytime charging, ensuring full capacity by dusk—critical for overnight energy needs.

The charger’s intelligent algorithm adapts to battery state and ambient conditions. During the constant current phase, it delivers 10A until voltage reaches 54V (90% SOC), then switches to constant voltage mode to prevent gassing. This two-stage process reduces heat generation by 40% compared to rapid charging methods. Users in solar applications benefit from the charger’s compatibility with MPPT controllers, enabling seamless transitions between solar and grid charging. The included temperature compensation feature adjusts voltage thresholds by -3mV/°C when batteries are below 25°C, preventing undercharging in cold climates. For mobility applications like golf carts, the charger’s 92% efficiency rating minimizes energy waste, making it ideal for fleet operations requiring daily charging.
| Charger Type | Charge Time | Cycle Life Impact |
|---|---|---|
| 10A Standard | 5 hours | 3,000–5,000 cycles |
| 20A Rapid | 2.5 hours | 2,000–3,000 cycles |
