Product Description
 Descriptions

Application: This is a high end protection circuit board developed by us by considering all factors which would has 

possiblity to damge the BMS . it has full set of protection than other normal PCB board . the Dimension of 

this Board is :42*90*9mm , which can be applied widely on Electric bike or Electric scooter vehicles etc or 

other 13S 48V Li ion Battery field . it has the different charge and discharge port with 5A rated Constant 

charge current 

 Feature and characteristics :

1) This Board has adopted with integrated chip managment solution with less quality risk and more stable working performance 

2) Working current is 20A constant current ,and this Board can be made with 40A constant current , please contact us if needs 

3) With weak electricity switch to control the discharge to prevent the drain of current during work-off time ( this BMS's On/OFF switch 

will cut-off the power consumption and output from all connection port , it will leave your battery at good status during work off time without

power consumption) 

4) With charge port protection function ,no voltage from the charge port  when disconnected with charge , O voltage output from 

the charge port .and with reverse connection protection function when user mixed the polarity of the charger ,it would not damage the 

BMS .

5) With Balance function and over-charge ,over-discharge , over-current protection ,short protection ,High temperature protection function ,

with 5V USB connection connector on the BMS . 

6) with MCU   controlling processing for charge current  limitation .( when the current exceeded the rated charge current , the BMS will cut 

off the charge so as to prevent any wrong charger to damge the BMS accident .
