I ran into the same headache with BMS instructions and ended up sketching my own wiring map just to keep things straight. One thing that helped me was taping the balance leads in order before plugging anything in, so nothing crossed over in the chaos. Mixing packs of different ages can work, but I always let them rest at the same voltage before tying them together to keep the BMS from fighting.

I like how hands-on this is, and one thing I found helpful in projects like this is marking each log before stacking so you’re not wrestling with heavy pieces trying to remember what goes where. I’ve also had good luck mixing a bit of chopped grass into clay for gaps since it dries with fewer cracks. Little tricks like that can save a lot of headaches once things start settling.

I stuck with LiFePO4 mostly because it buys me some peace of mind, but I still treat the setup like it could throw a tantrum any day. A decent BMS, fuses that match the gear, and a spot with airflow made a big difference for me. I keep the whole pack in a shed so if anything cooks itself, it stays outside.
