I have a JBD 100A BMS running a 270Ah 12v 4 cell Lifepo.
Suddenly, using the Overkill app, the battery started to discharge about 4amps without ANY power attached. So I disconnected battery from system and took the following reading from the Overkill App.
1. 3.105
2. 1.983
3. 0.046
4. 2.270
Please note cell 3 voltage
I then remove the BMS and tested each individual cell with a multimeter, results as follows:
1. 3.098
2. 3.053
3. 3.085
4. 3.125
As you can see the, the voltage difference, especially Cell 3, is amazing, I,m assuming unless someone can advise differently that the BMS is blown and requires replacing. I am already running a JBD on another 270Ah battery, which was wired in parallel to the above apparently faulty battery. Do I have to purchase a replacement JBD or can I use another BMS from a different maker
Many thanks
