Product description 
 
4S10A 12V Lithium ion  Battery Management system (BMS) is designed specifically for lithium ion  pack of nominal 14.8V 4 series cells of 3.7v.  
4S10A 12V LFP BMS has following salient features
The protection of batteries from over-charge, over-discharge, over-current, short-circuit
Short term waterproof 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.
Lithium Ion 4s10A BMS can measure, process and use the real time data of the battery to ensure the safety, stability and long life of the battery pack. The BMS 4S 10A comes with equalization function which facilitate to keep the cells at same level and ensure prolong life.
