How Does the 400A BMS Enhance Battery Performance?
The 400A Battery Management System (BMS) monitors voltage, current, and temperature in real-time. It prevents overcharging, over-discharging, and short circuits while balancing individual cells to maximize capacity. This system enables peak 400A discharge for hill climbs and accelerates charging by 30% compared to standard BMS units, ensuring consistent power delivery across 6,000+ charge cycles.
The 400A BMS utilizes dual-layer MOSFET arrays and 16-bit microcontrollers to achieve 99.97% current measurement accuracy. Its adaptive balancing algorithm redistributes energy between cells at 2A balancing current – four times higher than typical 100A BMS units. This prevents voltage drift during rapid charging (0-80% in 90 minutes at 1C rate). The system’s CAN bus communication enables real-time diagnostics through mobile apps, showing detailed metrics like cell impedance variance and state-of-health percentages.
| BMS Type | Max Discharge | Balancing Current | Cycle Life |
|---|---|---|---|
| 400A Advanced | 400A continuous | 2A active | 6,000 cycles |
| 300A Standard | 300A peak | 0.5A passive | 4,000 cycles |
What Are the Weight and Dimensions of This Battery?
Weighing 77 kg (170 lbs) with dimensions of 580x240x290 mm, the 72V 200Ah lithium battery is 35% lighter than equivalent lead-acid systems. Its compact design integrates 280 LiFePO4 cells in a rugged IP67-rated aluminum case, making it suitable for golf cart battery compartments without modifications.

What Is the Real-World Range on a Single Charge?
In golf cart applications, this battery provides 120-150 km (75-93 miles) per charge under normal conditions. Factors affecting range include terrain (20% reduction on hilly courses), payload (up to 500 kg), and speed (optimal at 25 km/h). Winter operation at -20°C maintains 80% capacity using built-in heating elements.
How Does Temperature Affect Battery Efficiency?
The battery operates at 95% efficiency between 15°C-35°C. At -10°C, capacity drops to 85% without heating; the integrated thermal management system recovers this to 92% within 15 minutes. High-temperature protection activates at 55°C, reducing discharge rates to prevent damage while maintaining 70% performance.
What Safety Features Are Included?
Safety mechanisms include:
1. Multi-layer short-circuit protection (response time <2ms)
2. Flame-retardant electrolyte
3. Crash-resistant cell architecture
4. Waterproof connectors
5. Self-diagnostic fault reporting via CAN bus
6. Automatic shutdown during thermal runaway conditions
The battery’s safety architecture features seven redundant protection layers. The ceramic-reinforced separators withstand 300°C before initiating shutdown, compared to standard 150°C separators. Crash resistance comes from honeycomb-structured cell holders that absorb 150J impact energy. The CAN bus diagnostics provide predictive alerts for 23 potential failure modes, from cell swelling detection (±0.1mm resolution) to electrolyte leakage monitoring.
| Safety Feature | Activation Threshold | Response Time |
|---|---|---|
| Overcurrent | 450A for 5s | 1.8ms |
| Thermal Runaway | 70°C cell temp | Instant |
