Specifications

 Specification:                                                                          

1.Battery Types: LiPo and LiFe cells

2.Cells Count :  3S - 8S

3.Maximal Voltage on P+ and P-: 35V

4.Maximal Voltage on B+ and B-: max. 35V

5.Charge Current:     up to 50A

6.Discharge current: 0~75A continue, 300A burst

7.Current drain for balancing: 300mA/cell.

8.Balance accuracy: <10mV

9.Over Charge Protection Voltage: 4.20V/cell (LiPo), 3.75V/cell(LiFe)

Features :

1.Detect and display pack voltage, difference of cell voltage and temperature, each cell voltage by microprocessor, 100% calibration before delivery make sure the high accuracy.

2.Over Voltage protection during charge, EJBMS-C8 will cut off charge and sound warning by beeper

3.Under Voltage protection during discharge, EJBMS-C8 will cut off discharge and sound warning by beeper

4.Over temperature protection during charge or discharge, EJBMS-C8 will cut off charge or discharge and sound warning by beeper

5.Over current and short circuit protection,

6.Cut off discharge when 75A to 300A discharge current for different continuous time. It means the e-scooter don't lose power under 300A, such as the e-Scooter can be powered at 90A for 1 second at least, and cut off, then resume automatically.

7.300A or more when short circuit, cut off discharge automatically and resume 10 seconds later.

8.Dual protection by program and hardware, more reliable.
