BMS8 is a high efficiency wide input voltage BMS, the device can detect and monitor 3S to 8S LiPo and LiFePO4 cells voltage and charge or discharge current, battery temperature in a smaller size.
- 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.
- Over Voltage protection during charge, BMS8 will cut off charge and sound warning by beeper
- Under Voltage protection during discharge, BMS8 will cut off discharge and sound warning by beeper
- Over temperature protection during charge or discharge, BMS8 will cut off charge or discharge and sound warning by beeper
- Over current and short circuit protection,
- Cut off discharge when 25A to 100A discharge current for different continuous time. It means the e-scooter don’t lose power under 100A, such as the e-Scooter can be powered at 40A for 1 second at least, and cut off, then resume automatically.
- 100A or more when short circuit, cut off discharge automatically and resume 10 seconds later.
- Dual protection by program and hardware, more reliable.
- Low Quiescent current design, BMS8 draw current from all cells to keep the cell voltage balanced and minimize the power consumption in stand-by.
