This LiFePO4 battery utilizes automotive-grade cells with 2600-cycle durability at 90% discharge depth. While the 51.2V nominal voltage matches standard 48V systems, the extended 47-55V range allows compatibility with conventional solar charge controllers. For example, pairing two units creates a 10.24kWh bank supporting 8-10 hours of residential backup power. Practically speaking, the 50A maximum charge current enables 2-hour recharges when using industrial-grade chargers. But what differentiates it from similar models? The integrated cell balancing ensures ≤2% capacity variance between parallel units.
| Parameter | LiGC48V100 | AGV Competitor |
|---|---|---|
| Cycle Life (90% DOD) | 26,000 | 12,000 |
| Max Discharge | 100A | 80A |
| Charge Temp | 0-55°C | -10-45°C |
What mechanical features ensure durability?
The battery’s 495×483×177mm chassis uses cold-rolled steel with anti-vibration mounts, supporting wall/floor installation. At 46kg, its compact form factor suits confined spaces like marine engine rooms.

Beyond structural resilience, the IP20 rating protects against accidental finger contact but requires dry environments. The modular design enables scalable configurations – 63 units can be paralleled for 322.56kWh systems. For instance, warehouse AGVs often use 6-unit arrays (30.72kWh) achieving 12-hour runtime between charges. Transitionally, the 31mm suspension bushings absorb forklift-induced shocks in industrial settings. However, operators should avoid direct water exposure despite the robust housing.

|---|---|
| Galvanized Steel Shell | Resists corrosion in marine air |
| Pressure Relief Vents | Prevents gas accumulation |
| Silicon Seals | Blocks dust ingress |
How does temperature affect performance?
Discharge works down to -20°C, but charging requires ≥0°C ambient temperatures. The BMS enforces thermal limits, reducing current by 50% at 55°C.
While the battery functions in Arctic conditions, capacity drops 25% at -20°C compared to 25°C operation. In photovoltaic setups, morning recharge cycles should wait until solar heating raises battery temperature above freezing. Transitionally, desert users must ensure adequate ventilation—prolonged 60°C exposure accelerates capacity fade by 0.1%/cycle. A practical example: Alaska’s fishing vessels use insulated compartments with 100W heating pads to maintain optimal 15-30°C operating range during winter.
What communication protocols are supported?
Dual CAN 2.0B and RS485 interfaces enable system integration, transmitting SOC, temperature, and fault codes. This supports Modbus/RTU protocol for SCADA monitoring.
In solar microgrids, the RS485 port typically connects to inverters for coordinated charge/dispatch cycles. The CAN bus serves higher-priority industrial networks—automotive assembly AGVs use this for real-time load balancing across battery strings. Pro Tip: Always terminate communication lines with 120Ω resistors to prevent signal reflection errors. For example, a 50-battery solar farm uses daisy-chained RS485 to monitor all units through a single gateway.

FAQs
Yes, but confirm your motor controller’s voltage range first – some 48V systems can’t handle the 55V peak.
How often should cells be balanced?
Automatic balancing occurs every charge cycle; manual intervention is only needed if voltage deviation exceeds 200mV.
Is the BMS waterproof?
No – the IP20 rating requires dry installation despite the rugged exterior. Use NEMA4 enclosures outdoors.
