Review: Great - Works great
Review: Multi-type battery charger - This PHONEFIX BA29 Battery Activation Detection Board seems to work as expected. Relatively simple to connect and run various batteries on this battery board. This battery board has many connection ports to different mobile device batteries to check and charge. The PCB look is pretty basic and operation is fairly simple. Functions decently and gets things going without having to rely on how finnicky some mobile devices and their charging shenanigans can be. Plenty of charge/power connections and interfaces. A decent value for what you're getting into.

Lack of documentation. I don’t even know if it’s worked you still have power that is portable even if you don’t use product.
