In this video I explain the three most practical ways to wire LiFePO₄ batteries in parallel, and how to choose the setup that fits your budget and system size. You’ll see a simple terminal-fuse (MRBF) layout, a single fused busbar setup using MEGA fuses, and a “dual busbar” / battery-combiner approach similar to the Victron Lynx style for larger banks.
I also cover the safety rules that matter—why every parallel battery must be fused, where to place a main DC disconnect, and how to think about current sharing without overcomplicating cable length matching. Finally, I compare the cost of each wiring method for a real example system so you can see what’s cheapest and what scales best as you add more batteries.
