Ep. 12 — 48V Battery Bank Install
Wiring 16s LiFePO4, BMS config, busbar torque specs, and the mistake that cost me $400.
I'm documenting every system on my 87-acre off-grid property — solar, water, comms, security, food. Get the checklists, product specs, and hard-won lessons so you don't make the same expensive mistakes.
Every major system on the property has a printable checklist — what to buy, how to size it, wiring diagrams, and the gotchas I learned the hard way.
