The JK BMS connected to a 12V/4s battery. But there is a catch...

In this video, I show you how to connect the JK BMS to a 4s battery and get it started and configured. The JK BMS usually connects to batteries from 15s to 24S only. It needs this higher voltage to start up and stay on. With a little trick however, we can make it work from a 4s and also 8s battery bank. But there is a slight downside of that...
This is a test only and I would not recommend this setup for a production installation.

The JK-BMS, its manual, the booster and also the 8S BMS with active balancer can be found here:
