Product Description
4S20A 12V LFP Battery Management system (BMS) is designed specifically for lithium-iron Phosphate battery packs of 48V. It can measure, collect, process and use the information data of the battery in real time and ensure the safety and stability of the battery.
4S20A 12V LFP BMS has following salient features
- The protection of batteries from over-charge, over-discharge, over-current, short-circuit
- Short term water proof to protect battery pack from extreme weather and tough dynamic conditions.
- Common Port design - 2 wires only, Charge and discharge port share the same port.
- BMS comes with balancing connection wire connector to reduce the wire complexity and number of solders.
- Dust proof, shockproof and anti-squeezing, protects circuit from external damages.
- BMS has passive balancing function which gives long life to the batteries.
- The appearance is sealed by injection moulding process to improve moisture-proof and oxidation-proof circuit components and prolong the service life of the products and batteries.
