Lithium Iron Phosphate (LiFePO4, LFP) is a kind of Li-Ion rechargeable battery for high-power applications, such as EVs, Energy storage, Power Tools, and so on. LFP cells feature high discharging current, nonexplosive, and long cycle life (>2000@0.2C rate, IEC Standard), but their energy density is lower than normal Li-Ion cell (Li-Co) (higher NiMH cell). Please click Knowledge on LiFePO4 battery to learn more details. LFP cell has a 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 the comparison between LFP and other rechargeable batteries. LFP battery has the lowest cost if considering its long cycle life.

Major parameters of the 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 circuits, switch off the load and resume normal.
4. Average voltage: average 3.6v voltage per cell.
