Protection Features:
- Low Voltage Protection: Automatically disconnects at 10.0V
- Over Voltage Protection: Automatically disconnects at 14.8V
- Short Circuit Protection: Automatically and safely disconnects battery
- Reverse Polarity Protection: Automatically and safely disconnects battery
- Over Temperature: Automatically shuts down until normal temperature recovery
Balancing Features:
- Internal cell reconciliation during battery operation
- Charge reconciliation for parallel and series configurations
- Ensures excellent balance between cells throughout battery life
Important Facts:
- LFP cells fail if voltage drops below 2.5V
- LFP cells fail if voltage exceeds 4.2V
- Cells do not auto-balance at end of charge cycle
- Differences between cells increase without balancing
BMS is indispensable for preventing damage to large Li-ion battery banks by preventing cell under/over voltage and managing temperature.
- LiFePO4 batteries are the safest lithium battery type
- Will not overheat or catch fire even when punctured
- Cathode material is not hazardous
- No negative health or environmental hazards
- Oxygen is bonded tightly to the molecule
- Chemistry is stable enough to accept charge from lead-acid configured chargers
Typical estimated life: 5-15 years, or 2000 to 8000 charge cycles. One charge cycle represents use from fully charged to fully discharged and fully recharged.
Recommendation: Always use LiFePO4/Lithium Ion solar controller, especially for UPS applications. Lead Acid controllers provide constant pulse current that may damage PCB protection circuits over time.
Warning: Lead acid chargers operate at 2.30V-2.45V per cell while LiFePO4 requires 3.65V per cell. Using lead acid chargers will undercharge batteries and prevent proper balancing. We recommend using bundled chargers specifically designed for LiFePO4 batteries.
