But there has been some scepticism if they are genuinely active balancing and quite a few conflicting forum posts. Some have even claimed the ‘1R0’ inductors are actually 1 ohm resistors. The more traditional passive balancer boards will simply dump any excessive charge into a resistor, wasting this energy. For example, if the maximum voltage threshold was set at 4.2V, once the cell’s terminal voltage exceeded 4.2V, any excess charge would be dumped into a resistor and dissipated as heat until the terminal voltage fell below 4.2V. Active balancer boards are designed to divert excess energy from the cells with the highest voltage into cells that still require charge. To find out how these cheap boards work, I jumped in and paid $8.26 USD for a 3S version from the Aliexpress Dykbhuang Store. This board has a PCB part number of JW-3S1.2A V3.0. By decoding the part number, the designer appears to have the initials JW. This is a 3S version 3.0 PCB with a maximum balancing capability of 1.2A.
