a little post to give you a feedback
I made a LIFEPO4 battery 8 months ago for my camper.
I bought on aliexpress from a well known supplier 4 cells 3.2V of 320Ah.
I took a BMS DALY 200A.
I did everything right following the advice of the forum and youtube videos (balancing, battery construction, BMS configuration, ....)
On this battery there were the 12V lights of my VAN and a 2000W converter. (12->220V).
Battery installed under the passenger seat.
This battery was charged with a victron mppt and solar panel that provided max 20A.
Everything worked great for 8 months.
But 2 days ago when we were leaving for a weekend with the vehicle, a whistling noise under the seat.
White smoke started to appear.
We stopped and a thick white smoke came out for about 30 minutes.
A liquid was coming out of a cell and there was a strong release of heat that melted the battery tower.
I don't understand what happened.
The DALY salesman tells me that it is a problem with a poor quality cell.
The cell seller (I didn't give his name but it starts with Lit....) tells me that it's because the battery has been used too long. incomprehensible ????????
if anyone has an idea of the cause?
