Application:






Main Function:
Over Charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection.


Advantage:
1.Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.
2.Strong load ability, constant discharge current can be 350A max,use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help cooling.
3.IC itself has power balancing fucntion.The circuit is simple and reliable.
4.Typical voltage detection of each cell. Each battery will be prevented from over charge or discharge ,over current and short circuit .
5. Extreme low power consumption
6.BMS is coated with a conformal coating, for INSULATION, MOISTURE-PROOF, LEAKAGE-PROOF.


Packing&Shipping


Pack the BMS board in an anti-static bag, add foam to prevent impact, put a layer on each partition, and then put it in a carton. Four cartons are placed in a larger carton.
