Note: This BMS is for Lithium-ion (Li-ion)/Lithium-polymer (LiPo), 3.7v/4.2v cells.

 

Description:

This BMS balance board is used for a lithium battery pack to equalize (balance) voltage and protect the cells. The BMS uses COMMON Port connections for both charge and discharge. 

 

Battery compatibility: Voltage of 2.7V (Empty) - 4.2V (Full Charge) Li-ion battery types

Charging input voltage: 29.4V – 30V (Max)

Maximum starting current: 60A (Max)

Discharge continuous current: 30A (Max)

Charge current: 20A (Max)

Board Size: approx. 108mm*34mm

Package includes: 1 x BMS Board Li-ion, 1 x Wiring Connection Guide

 

The BMS has optional special spot weld pads to allow direct connection of a nickel strip welded to the BMS. These pads can be removed or left on when using solder and wires.

 

*Wires are not included. Recommended wires of 12AWG-20AWG will fit on the BMS.
