BM16LP / BM16LF V3.1

Chargery Battery Saver BM16 have two model for LiPo and LiFe battery pack separately, the model is BM16LP and BM16LF. Now two models are updated to V3.1, new version can do any cell combination such as 3S + 6S or 6S + 6S.

BM16LF is 3S to 16S LiFe battery saver with TFT color LCD, totally monitor each cell voltage, battery temperature, battery SOC--State of Charge-- during E-Bike, e-scooter etc. driving. The over discharge cell voltage, the highest battery temperature, battery SOC can be programmed.

The device is a high performance microprocessor controller, it can detect and display each cell voltage, record lowest cell voltage during driving, so you will find the worst cell, more safety use the battery.

it can sound warning by 85dB beeper and RED LED flash warning while any cell voltage under setup value, battery temperate over setup or battery gauge under setup, prevent any cell from over discharged.


BM16LF / BM16LP V3.1 is released, for more information, please check with the data sheet.

BM16LF V3.1 data sheet (356K )

BM16LP V3.1 data sheet (354K )
