I’m building a 20S9P battery pack from recycled laptop battery. The battery have a cell level fuse.
The battery worked fine until there is a short in the votol em100 controller. When the controller shorted out there are 4 cell fuse that is blown, the bms is also blown. The 4 battery have a black burned marks on it. When I check the voltage, the battery was in normal voltage. So i Replace the bms and put another cell fuse to the 4 battery. (The photo is just as reference).
The problem is when I use the battery, the bms keep shutting off. When I’ve check the cell group voltage, that group that has the cell fuse replaced is causing the low voltage cut off on the bms. The group do not have a high cell Self discharge.
I’m thinking of making a 1S4P battery pack and connect the battery to the damaged cell group in parallel. Because to replace the 4 pcs of 18650 battery means that I have to dismantle the battery pack.
What do you think about this solution?
Any help is appreciated.
