Remove the whole PCB and reconnect again, and connect to the charger it should work perfectly fine . Sometimes, the motherboard needs to reseted and the best way is to remove and reconnect in most of the milwaukee batteries. If that doesn't work there must be a mosfet that has been damaged. Thank u❤
Milwaukee batteries do not balance cells, so in time the disbalance grows so much that once cell may be fully charged, and the others depleted. If all cells are evened out, there's a chance the battery might still be good.
Great video, Scott. Sort of like a bad crapacitor! Would you replace just the bad cell or all of them? I have done a few NiMH packs but they were all very old and very dead. You keep forgetting that really fancy milliohmmeter 😊. Regards, David
I wasn’t even sure the controller would reset, I gave it back and they put it on the charger, it reset. Ideally I would replace those 2 bad cells at the very least, the other cells were still fine really.
Nice vid. Great explanation of how the batteries work.
11:50 and 15:30 Kitty has some valuable advice on solving the problem!!!

It's possible that shorting the battery negative to the circuit negative across the mosfet will remove the protection.

I wonder if the choice to use 10 cells instead of 5 is a space consideration, more compact?
@@jrsydvl100 probably two reasons, lower cost cells and increased current handling capacity.

Is it possible that "broken" connection was not broken? Perhaps when screwed together, it's a pressure contact between the tabs.
@@bblod4896 nope it was definitely broken
I would remove those 2 cell replace them with new ones.
Hello. Just put it back on the original milwaukee charger and it will go away.
@@oswanator690 I had to fix the battery first, and I didn’t have the charger.
