LiFePO4 Technology FAQ
Why Lithium Iron Phosphate (LiFePO4)?
Safest mainstream li-ion battery type
No thermal runaway or catastrophic meltdown risk
Extremely long cycle life (up to 10,000 cycles warranted)
High discharge and recharge rates up to C/2 continuous
Round-trip efficiency up to 98%
Perfect energy storage solution
Battery Management System (BMS)
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
Is BMS Necessary?
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.
Battery Safety
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
Life Expectancy
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.
Solar Charging Compatibility
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.
Charger Compatibility
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.
