Product Description

3S-8S 1A-8A Bidirectional DC-DC Smart Active Balancer With CAN Communication For Lifepo4/Li-ion Battery Cell

Product Description

8A Bidirectional DC-DC Smart Active Balancer Equalizer 24s 12-72volt 8A max - NMC/ LFP LTO/SIB - For Lithium Battery Packs

The 100-200AH capacity battery pack can reach less than 1mV after being fully charged and balanced. The smaller the capacity, the better the effect.

Equipped with Bluetooth connectivity, the equalizer pairs with a dedicated mobile app. Users can view data such as individual cell voltages (including the highest, lowest, and average values), maximum voltage differential, total pack voltage, real-time balancing current, operating duration, balancing status, and device temperature. Balancing parameters can also be adjusted directly through the app.

This device is primarily used within battery packs for small sightseeing vehicles, personal mobility vehicles, shared electric vehicles, high-power energy storage systems, base station backup power supplies, and solar power stations. It is also suitable for battery maintenance, repair, and restoration applications.

8S Wiring Diagram

A single equalizer supports 3S-8S.
The following figure shows the installation and wiring method for a 8S battery pack:

CAN Communication Smart Active Balancer Bidirectional DC-DC Battery Equalizer for 3S-8S Lithium Battery Packs

3S Wiring Diagram

When the total voltage is at least 10V, it can be used for battery packs with fewer than 8 series-connected cells;

leave the unused pins unconnected. Refer to the installation and wiring instructions.

15S Cascade Wiring Diagram

When used in a cascaded configuration, there must be at least one battery cell between every two equalizers to serve as a common point for energy exchange. Installation and wiring method:
Take 15S as an example below, the installation and wiring method is as follows:

Wiring Precautions:

1. Installing a balancing board requires a certain level of technical knowledge in electronics.

2. When wiring, first solder the terminal connectors (with wires) to the battery pack, then plug them into the balancer.

When inserting the terminal connectors, ensure the "B-" terminal is connected first; insert the connector on the "B-" side initially.

Follow a sequence of connecting from the smallest (lowest voltage/index) to the largest (highest voltage/index).
