I did this and it started working again!

Will said in a post the way to reset the BMS is to short the P- and B- ----------------------- Will: It's a daly. Usually need to reset them by shorting out the P- and B-. It will turn it out and you will have full voltage. As long as your balance lead is attached correctly. So take the P-...

I did exactly that: 1 - 3.283 2 - 6.55 3 - 9.83 4 - 13.10

With the BMS hooked up correctly, current will not flow through it. Is this a sign that the BMS is malfunctioning?

Daly 4S 12V 200A

I doubt no more than 20 Amps total at one time. The Daly BMS that I installed with the battery is rated at 200 Amps. Pretty much overkill, it looks like. But since I had no idea how to determine the rating, I figured better too much than not enough. I think also maybe I had in mind the...

How do I test a BMS if it actually is working or not? If it is without defect, how do I reset it to get it passing current again?

How do I know what Amp rating to get for a BMS? Solar Charge Controller - 30 amps Battery - 12 V LiFePo4 4 cell 200Ahr Solar Panels - 2 100 W

3) How do I reset the BMS?

1) Is there any way to test the BMS to see if it's bad? 2) My battery is 200 Amp Hrs -- Does my BMS have to be 200 Amps to use with my battery? Or is that overkill?

I'm not sure unplugging the BMS and plugging it back in is the way to reset the BMS. Is there a different way to do this?

Cell Voltages: 1 - 3.284 2 - 3.274 3 - 3.275 4 - 3.273 All 4 cells: 13.1 New battery, never used. I've never balanced the battery. Don't know how to do that.Could that be a problem? Maybe the BMS is bad, is there a way to test it?

I've already tried a reset that didn't work.

What does dmm stand for? Can I get one on Amazon?

Excuse my ignorance, but what are balance leads?
