Battery Management System (BMS)
The battery management system (BMS) built into each battery ensures that the battery switches off in the event of under voltage or overload and automatically turns on again when the problem is resolved.
- Protection against under voltage by switching off the load
- Protection against over voltage by reducing charging current
- Shutdown in event of excess temperature
- Charging stopped in case of under temperature
- Passive and active balancer integrated
- Optional Victron device communication
- Bluetooth app for battery monitoring
- Self-heating function for low temperature charging
Key Benefits
- High performance traction/storage battery
- Integrated battery management system (BMS)
- Safe lithium technology (LiFePO4)
- High cycle life (>3000 cycles @ 100% DOD)
- High max continuous discharging current
- Lightweight compared to lead acid batteries
- Direct replacement for lead acid batteries
- Low self-discharge rate
Applications
- Motorhomes, caravans and RVs
- Photovoltaics and solar systems
- High performance traction/storage
- Fishing boats and electric marine motors
- Mobile power supply for camping
- Emergency power supply/UPS systems
Storage and Transportation
- Must be properly packed and protected during transport
- Transport according to UN3480/UN38.3 regulations
- Never lift by terminals - use handles only
- Store at -10℃ to +30℃
- Transport at 50-60% charge level
- Charge every three months during storage
Important Instructions
Do not open the LiFePO4 battery without consulting the dealer. Unauthorized opening voids the warranty.
- Use only for intended applications
- Protect against short circuits
- Installation by qualified specialists only
- Avoid direct sunlight and temperatures above +60°C
- Use compatible chargers only
- Disconnect devices during long storage
- Ensure proper assembly
- Avoid physical damage (dropping, drilling, etc.)
- Keep battery dry and clean
- Observe correct polarity markings
- Capacity may vary with temperature and charge/discharge rates
- Maximum four batteries in parallel (custom BMS required for series)
- Equalize charge levels before connecting
- Do not mix battery types or manufacturers
Installation Guidelines
Lithium batteries are heavy. Ensure secure attachment and use proper lifting equipment. In an accident, unsecured batteries could become projectiles.
- Ensure correct polarity when connecting
- Reverse connection will damage BMS irreparably (not covered by warranty)
- Use proper mounting hardware and techniques
- Follow all local electrical codes and regulations
