Features
1.Detect and display pack voltage, difference of cell voltage and temperature, each cell voltage by microprocessor, **0% 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 *5A to **0A discharge current for different continuous time. It means the e-scooter don't lose power under **0A, such as the e-Scooter can be powered at *0A for 1 second at least, and cut off, then resume automatically.
7.**0A or more when short circuit, cut off discharge automatically and resume *0 seconds later.
8.Dual protection by program and hardware, more reliable.
