VERY VERY VERY SAD ........
My thorougly tested 8x 272Ah lishens have been in my campervan for about a month now. Yesterday I walked by the van and I smelled smoke.
I went in and this is what I saw:

I'm not sure if my camper can be repaired :-( .. EVERYTHING EVERYWHERE under thick black soot. Some windows melted, every plastic bit melted from front to back. Some holes burned through the wall. Brand new Maxxfan melted, fridge melted, heater melted, charger, victron mppt, victron 220v converter, acdc converter everything melted. All doors of cubboards burned. Terrible, I loved this camper and I have owned it for many years. I just did a big upgrade with all of the above appliances new last year.
This is what it looked like before yesterday:

I'm not sure what has caused it. It was charging at a rate of about 20A that night I think.
The four cells on one side have swollen terribly an a few are bursted open.
Maybe they were terribly overcharged, and the JBD / overkill BMS hasn't stopped the charging when one or two cells where full.
Or there has been some kind of internal problem in the cells..
