## Description

Active balancing module for 2S Lead-Acid batteries, optimizes charging and extends battery life by transferring energy from the more charged battery to the less discharged one when the difference exceeds 50 mV. Offers up to 10A of balancing current, backlit display for quick monitoring, mounts on the rail and allows multiple modules to be interconnected in series for multi-battery systems.
BMS 2S module for Lead Acid batteries, with active balance and the possibility to connect several modules in series for more than 2 inserted batteries.
The active balance is advantageous because the transfer is made between cells, from the more charged cell to the more discharged cell, when the difference between them exceeds 50 millivolts. The balancing current between the cells is between 0 and 10A.
Initially connect the wires to the battery to avoid any erroneous connection to the terminals that will cause the module to burn! Make sure that you have connected the wires correctly and finally connect B1+, B1-, B2+, B2- in turn.
Connecting and disconnecting the accumulators will be done EXCLUSIVELY in the order B1+, B1-, B2+, B2- when connecting and B2-, B2+, B1-, B1+ when disconnecting . Failure to comply with this order will burn the module and lead to loss of warranty.
The module can be set in the following configurations:
B01: For Lithium batteries in the 2S configuration, nominal voltage 7.4V
B02: For Lithium batteries in the 3S configuration, nominal voltage 11.1V
B03: For Lead Acid batteries with a nominal voltage of 12V
B04: For LiFePO4 batteries in the 4S configuration, nominal voltage 14.4V
B05: For Lithium batteries in the 4S configuration, nominal voltage 14.8V
