Product ID # 5397
Part Number:
PCM-B01S10-394-1S



PCM-B01S10-394-1S is a smart balance module for individual LFP cell with capacity > 3.5Ah.

Working principal:  

Each 3.2V LFP cell has a small difference in internal resistivity ( so called impedance ) due to fabrication tolerance. Especially for cell's capacity >3.5Ah and in application require very high discharge current ( >5C ) 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 700mA 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 (PCM-B01S10-394-1S) 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.

Specification

Note:  

  • The LifePO4 Smart charger must have cut-off voltage = 3.60 +/- 0.025V, otherwise, this balancing board won't perform balancing charge function. 
  • 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!
