Product Description

18 Years Factory ODM&OEM Lithium Battery BMS 20S 30A 84V Lithium Battery Circuit Protection Board PCM BMS For Lifepo4 18650 Battery Pack

1. PCM-L20S30-G65 BMS can be used for 20S 30A battery pack
2. According to your requirements, it can be applied to Li-ion battery or LiFePO4 battery pack.
3. The main functions are: over-charging protection, over-discharging protection, over-current protection, short circuit
protection, temperature protection, balance function etc.
4. According to your requirements, we can develop PCM of different sizes and structures.
Advantages:
1. The protection board is made of high quality MOS (such as Infineon MOS) and imported IC (Mitsumi) to keep your battery for a longer cycle life.
2. when with a high working current, the high quality aluminum alloy heat sink has a good heat dissipation function.
