The 36V 100Ah LiFePO4 golf cart battery with Bluetooth and 200A BMS delivers unmatched power density (160Wh/kg) and 4,000+ cycles at 80% DoD. Its 1000A peak current enables instant torque for steep hills, while the integrated battery management system protects against overcharge/overload. The modular design allows capacity expansion up to 400Ah through parallel connections.

How Does the Built-in BMS Enhance Battery Safety?
The 200A continuous/1000A peak BMS utilizes triple-layer protection with MOSFET switches and thermal fuses. It monitors individual cell voltages (±0.02V accuracy) and temperatures (-20°C to 60°C operational range). The system automatically disconnects during short circuits (response time <50μs) and balances cells during charging (2A active balancing current).
What Advantages Does Bluetooth Connectivity Provide?
The Bluetooth 5.0 module enables real-time monitoring through dedicated apps (iOS/Android). Users track voltage (36-42V range), current (±250A measurement), and state-of-charge (1% resolution). The app stores 6 months of historical data and sends push notifications for abnormal temperatures (>55°C) or cell imbalance (>0.3V difference).

Can This Battery Replace Lead-Acid Systems Directly?
Yes, the battery’s dimensions (522x240x218mm) match standard lead-acid trays. It operates with existing 36V chargers (CCCV profile required) but charges 3x faster (0-100% in 2.5 hours at 40A). The built-in step-down converter maintains 36V output even when cells dip to 30V, preventing controller shutdowns common in lead-acid systems.
What Maintenance Practices Extend Battery Lifespan?
Annual capacity calibration (full discharge/charge cycle) maintains SOC accuracy. Store at 50% charge in dry environments (30-70% RH recommended). Clean terminals quarterly with dielectric grease to prevent corrosion. Avoid continuous discharges above 150A (5-second bursts permitted). The modular design allows individual cell replacement without full pack disassembly.
For optimal performance, users should implement a structured maintenance schedule. Terminal cleaning should involve disconnecting power and using a brass wire brush to remove oxidation. When storing batteries through winter months, maintain ambient humidity below 60% using silica gel packs in storage containers. The table below outlines key maintenance intervals:
Maintenance Task | Frequency | Optimal Conditions |
---|---|---|
Capacity Calibration | Every 12 months | 20-25°C ambient temperature |
Terminal Inspection | Every 3 months | Dry environment |
Full System Scan | Every 6 months | 50% SOC state |
How Does Temperature Affect Performance?
Between -10°C to 45°C, capacity remains at 98-100%. At -20°C, capacity drops to 85% but with built-in self-heating (5°C/hour warming rate). High-temp operation (55°C) reduces cycle life by 15% but includes forced air cooling via internal fans. The BMS automatically reduces current by 50% when core temperatures exceed 50°C.
Lithium-ion chemistry exhibits distinct thermal characteristics that users should understand. In sub-zero conditions, ionic conductivity decreases, temporarily reducing available capacity. The battery’s self-heating function activates below -10°C, drawing power from the pack itself to maintain operational readiness. This feature proves particularly valuable for golf courses in northern climates, enabling reliable cold starts. See temperature-performance relationships below:
Temperature Range | Capacity Retention | Charge Efficiency |
---|---|---|
-20°C to -10°C | 85-92% | 78% |
0°C to 45°C | 100% | 99% |
50°C to 60°C | 95% | 85% |
What Certification Standards Does It Meet?
Certified to UN38.3 (transport), IEC62619 (industrial), and UL1973 (stationary storage). Meets IP67 waterproof standards (submersion up to 1m/30min) and MIL-STD-810G vibration resistance (5-500Hz random vibration testing). The cells use A-grade LiFePO4 chemistry with 99.9% purity electrolytes.
Expert Views
“This battery’s 0.5C continuous discharge (50A) and 10C pulse (1000A) capabilities redefine golf cart performance. The real innovation is the hybrid BMS that combines FET-based protection with mechanical contactors – it eliminates voltage drops during high-current bursts while maintaining safety redundancy.”
– John Michaels, EV Power Systems Engineer
Conclusion
The 36V 100Ah Bluetooth-enabled lithium battery represents a technological leap with its adaptive thermal management and smart monitoring capabilities. Its 15-year design life (with 5-year full warranty) and 93% round-trip efficiency make it the most cost-effective solution for golf course operators and recreational users demanding reliable, maintenance-free power.
FAQs
- Can I charge this battery with solar panels?
- Yes, compatible with 100-450VDC solar inputs through MPPT controllers. The BMS accepts fluctuating voltages (32-58V range) and includes anti-reverse charging protection.
- How many golf holes per charge?
- Typically 54-72 holes (100-150km range) on flat terrain with 400kg load. Hilly courses reduce range by 25% but regenerative braking recovers 12-15% energy during descents.
- Is cold weather operation possible?
- Yes, with automatic electrolyte heating below -10°C. The self-heating function consumes 3% SOC/hour but maintains optimal performance. Use insulated battery blankets below -20°C.
