E&J Tech group is not only professional in custom Li-polymer and LiFePO4 battery pack designing and producing, but also strength on the lithium-ion battery cell monitor and saver field.

       

E&J Battery Cell Monitor and saver BCM16ELF(BCM16ELP) is for 3S ~ 16S LiFePO4(LiPolymer) battery applied to E-bike, E-scooter, Electric wheelchair, electric trolley, electric medical equipments, etc., High light red LED and loud beepers (85Db) make sure battery operation safety. The unit is with TFT color LCD display battery voltage, cell voltage, 2 battery temperature, and battery SOC (State ofCharge).

You can setup over discharge warning cell voltage, over charge warning voltage, the highest battery temperature and the lowest battery gauge for warning.

 

During battery discharge, if any cell voltage under setup value, or battery temperature over setup or battery gauge under setup, the BM16LF can sound and LED flash alternately prevent any cell from

over discharged. 

During battery charge, if any cell voltage over setup value, or battery temperature over setup, the

BCM16ELF(BCM16ELP) can sound and LED flash alternately prevent any cell from over charged. 

In any case, when cell voltage difference is over setup value, the unit can alarm.

When stop driving your bike or scooter,etc.., you can check the lowest cell voltage, so you can find the worst cell---the lowest voltage cell.
