please don’t misunderstand me. I did ask for high resolution pictures. Electricity is a wild and dangerous thing.Here you are absolutely wrong.
Not ZERO reason for the wires to be placed like that.
Some people like an easy score.
Those people frustrate me, and are the reason many people opt out sharing their mistakes, what is the most educational!
I didn't think/expect @Supervstech is one of them!!
If you don't understand what you see, ASK!
I would really like to look everything over and see where all the wiring goes.
you may not think the mass of wires could possibly be the culprit, but it could. 1.5A on balance wires, Cris’s crossed around, and you have heat concentrated on overlapping conductor insulation. Heat could eventually allow insulation issues, and failures can happen. Imagine the BMS thinking one cell was at cutout, and trying to balance when the cell actually wasn’t.
as you pointed out in the first post… professional built and factory BMS makes all the difference. Welded contacts, and perfect banding make for a very reliable pack. Something we mortals just cannot handle at home.
Don’t think I am stating the spaghetti IS the issue… but it very well could have been a part that instigated the failure.
obviously, if the high res pictures don’t show anything, looking at it post Mortum isn’t going to reveal much…
I’m not trying to blame you for the fire… I’m trying to impress upon every member reading this thread how little it takes to go wrong and cause serious issues.
