@hardtop: I have a battery monitor on it. I know what it is drawing and for how long. Always stops at 47% and 11.9V Well after 36 hours there was no change at all. The whole thing is moot now. I decided to open it. Went well, but as i was pulling the cells out, one of the cells burst...

Thanks for all your help. Ok, I will charge the battery, then set my power supply to 14.4V and let it sit. I do believe I already tried this, but seeing a current of 0.000 amps I thought it was not operational. Does this mean that the BMS was shutting off?

Hi, I have a Scream Power 12V 100AH battery which I bought 2 years ago. I used it 2 times in the past for a fishing trip of 4 days. The fish finder draws 1.7A. Both of these times it worked properly but it did not get discharged much. This year I went on a trip that was 7 days long. At 48%...

Ok, so I am using a Silgent bench power supply. I set the voltage to 13.8V and the current to 5A. The power supply will indicate the actual current draw and voltage as well. When I first connected this, it reads the full 5 amps. Slowly the amperage decreased until it reached 0.5A and then...

During charging the battery voltage reached over 14V and then the charger shut off. After a while the battery voltagew was at 13.6V When the 1.7A load when on it went to 13.3V and stays there for hours. It acts the same with two different chargers, a 6amp and a 20A. The battery monitor is a...

lol...at the time, there were not too many options out there. I do have a lab grade power supply. What should the current be set at? Thanks

I guess I am just not getting this or maybe I am.... So the battery was charged to maximum. I waited a little while then I attached a bench supply set at 14.4V 5A. Immediately the supply indicated it was outputting 5A and then the current started dropping. The power supply indicated that the...
