Lithium Iron Phosphate (LiFePO4, LFP) is kind of Li-Ion rechargeable battery for high power applications, such as EV , Energy storage, Power Tool and so on. LFP cells feature with high discharging current, non explosive, long cycle life (>2000-0.2C rate, IEC Standard), but its energy density is lower than normal Li-Ion cell (Li-Co) (higher NiMH cell). LFP cell has 3.2V nominal working voltage and shall be cut-off power at 3.6-3.8V per cell during charging. Please see the table below to see comparison between LFP and other rechargeable batteries. LFP Battery has the lowest cost if considering its long cycle life.

Major parameters of protection board:
1. Overcharge protection: Starting protection in the voltage range of 15.0v -15.6v,resume normal under the voltage 15.0v.
2. Over discharge protection: Starting protection in the voltage range of 8.0v-8.4v,resume normal over 8.4v.
3. Short circuit protection: Starting protection when short circuit,switch off the load,resume normal.
4. Average voltage: average 3.6v voltage per cell.
