Hi everybody,
long time lurker here. I thought it might be time to share what I’ve done so here it is.
my 3s34p battery packs made from Samsung 35E cells extracted from bad BMS ebike packs, all test 100% capacity and internal resistance is according to data sheet. It’s designed for low current, less than 200W hence the nickel busbars and 14 gauge wire. This battery sits in a steel ammo can. BMS is external and is in use when charging and discharging but can be removed if necessary. Every cell is fused to 3 amps and fuses are spot welded to cells.
This may sound like overkill, but each ammo can is gonna have its own on board arduino controller hooked up to mosfets and programmed to shut off the power in and out if any parameters such as temperature, voltage, and maybe humidity levels are breached...sounds like a BMS on top of a BMS...
Can anyone suggest any improvements?Always want to be as safe as I can be.
