Part Number:
BMS-G40BL



A smart balance module used in a battery pack for individual LFP-G40 LFP-G60 and LFP-G100 cell to improve battery pack's cycle life!  

Working principal:   Each 3.2V LFP cell has a small difference in internal resistivity ( so called impedance ) due to fabrication tolerance. Especially in application require very high discharge current ( >40A ) which will cause unbalanced voltage in each cell during charging. When building a multi-cells battery pack (in series or in parallel), unbalanced voltage will reduce battery pack‘s energy power and life cycle significantly.

The balance module will keep each LFP cell’s voltage at 3.60V peak during charging by draining excessive voltage with a 500mA discharge current. It will wait for other cells within the pack to reach same voltage level to ensure all cells within the pack are balanced.

Adding the balance module to each LFP cell before making a battery pack will maintain battery power, increase cycle life and save money. Using this balance module means you don't need a pcm ( protection board with balance function) but can use a pcb (no balance function) instead.

Note:  

  • This balancing board won't perform over-discharge protection function. You must not discharge the battery pack below 2.5V/cell.
  • If over discharge below 2.5V/cell, please recharge the pack right away. Otherwise over-discharged battery pack can not recover!
