Lithium Iron Phosphate (LiFePO4, LFP BATTERY) 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.

Chemistry	Voltage	Energy Density	Working Temp.	Cycle Life	Safety	Environmental	Cost based on cycle life x wh of SLA
LiFePO4	3.2V	>120 wh/kg	-20-60 °C	>2000(0.2C rate, IEC Standard)	Safe	Good	0.15-0.25 lower than SLA
Lead acid	2.0V	> 35wh/kg	-20 - 40°C	>200	Safe	Not good	1
NiCd	1.2V	> 40wh/kg	-20 - 50 °C	>1000	Safe	Bad	0.7
NiMH	1.2V	>80 wh/kg	-20 - 50 °C	>500	Safe	Good	1.2-1.4
LiMnxNiyCozO2	3.7V	>160 wh/kg	-20 - 40 °C	>500	better than LiCo	OK	1.5-2.0
LiCoO2	3.7V	>200 wh/kg	-20 - 60 °C	> 500	Unsafe w/o PCM	OK	1.5-2.0

Major parameters of protection board:
