Li-ion Battery Protection for 18650 BMS PCB Board Balance 48V 13S, Li-ion Lithium Cell 20A

I put it on my battery and when i plug my charger in first it would start charging and then just cut off. Sooo it dont work.

Tested faulty from the factory.

I'm pretty impressed with this BMS board it has little LED lights that light up when the battery reaches its full charge which is nice it shows that it's working. I also measured some current in the balance mode, not exactly sure what the current was as it was a voltage drop across a wire but at least I did see some balancing going on I'm assuming C- is for the charger and P - is for the power or load would have been nice to see some pictures on how to hook this up. I'm planning on using these with some Nissan Leaf batteries in the future for an electric car project if you Google my name Steve clunn or #electriccarsbygreenshed in you can get more information. I've had some time to put together my leaf batteries and have two of these modules on their hooked up with my relay circuit to turn off the controller for a car and a relay for the charger. I just did a charge on the batteries and noticed as all the little lights on top of this module we're lighting up that a little blue light came on when the charge circuit in the BMS turned off. Kind of a nice feature let you know when things are done charging.
