Product Description
Lithium Battery BMS 20S 25A 84V 18650 Battery Circuit Protection Board PCM BMS For Lifepo4 Lithium 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.
