## Description

Optimizes the balancing of 4-10S Li-Ion packs by actively transferring energy between cells, reducing voltage difference and extending battery life. Provides active balance up to 1A depending on unbalance, operates up to 42V, has standby consumption of only 5uA and equalization accuracy ±20mV, includes balance wiring with 10S compatible plug.
Active hardware balancing module for Li-ion, LiFePO4 and LTO batteries, capable of a transfer between cells of up to 1A.
It can manage between 4 and 10 series of batteries (verified with Lithium-Ion, we recommend a minimum of 5S), having a balancing current between 0-1A, variable depending on the voltage difference between the cells (the bigger the difference, the bigger the current).
The product comes with balance wires with a compatible 10S plug.
Specifications:
Compatible battery type: Li-ion, Li-Po, up to 4.2VDC when charged
Swing current: 0-1A
Dormant current: 5uA
Conditions for activating swing: Individual cell voltage above 3.1V (+-0.1V)
Balance break conditions: 3.0V (+-0.1V)
Operating temperature: -20°C to 60°C
Swing method: Active swing
Equalization accuracy: ±20mV
Dimensions: 49 x 87 x 18mm
Use:
Make sure the module is connected correctly according to the instructions specified for the battery type.
Before powering, remove the plug from the module and perform the soldering on the battery terminals. Afterwards proceed with the insertion of the balance plug in the module.
In the case of use in a configuration smaller than 10S, proceed with connecting the batteries starting from the NEGATIVE terminal (0V) Next, connect the rest of the cells. The wires that remain without connected terminals will remain free (in the air) but the LAST RED WIRE will be connected to the END POSITIVE . Only in this way will the module be powered.
