Seriously, if anyone has any good BMS cards from any bad battery modules, I'd be interested in buying them from you. The modules are in better shape than the BMS cards. I could use 3-4 cards if anyone has them.

Some of the BMS cards have rewired their own circuits. Could this be the beginning of the AI attack that Elon Musk has feared so much? His circuit boards are forming their own synapses!

Thanks, I've been wondering what the possibility is of spontaneous combustion.

I got to try out my new ultrasonic cleaner. Here is the after of the above circuit board.

So the top side looked pretty good. The bottom ... not so much. Hey Car Guru, can I borrow your plastic knife?

This is the 0.1 volt module. I had on my high voltage gloves, rubber soled boots, and was kneeling on a thick rubber pad. Then I noticed my knee was wet. :eek:

9 are 21.x and one is 19.7 volts. I'm taking out the module that's 0.1 shortly to take a look at it.

On to the battery pack. Has anyone ever repaired the cells in one of these? I have 11 cells that measured in the low 20s, one with 0.1 volts, one with 7.5, one with 3.5 volts. Any advice?

9 Here is the male end of the connector. You can see the corrosion. It cleaned up well, though.

Yeah, this is on the top of the pack, facing up so it collects water.

Sorry for your loss, I know how traumatic hurricanes can be. I lived in Puerto Rico during Hugo and Georges and in South Florida for Wilma and Katrina and a year ago Hermine hit here in Tallahassee and our electricity was out 3 weeks. In Puerto Rico, after Georges we didn't have running water...

This is the HV connector on the top of the pack. It was full of water and I suspect it may have been the entry point for water in the pack.

Anyone know what this little connector on the bottom of the battery pack is for? On left rear and has a round black cover that takes a T100 star key.

Here is an update at where I'm at now: It makes a big difference whether it is salt water or fresh water. If you have watched Car Guru's Youtube videos, everything in his car has an incredible amount of corrosion. Even his aluminum parts were highly oxidized. On my MS most of the aluminum looks...
