Hey all, I’m starting the process of building a 12S2P battery (30Q, BMS Charge Only) for my upcoming Icarus build. My goal is to build a 1 stack, flat pack but I’m unsure as to the best layout. Here’s what I’m planning on going with thus far…
I’ll be using the boss spot welder with 10mm x .15mm pure nickel strips. I’ve already placed fish paper ring/covers over each of the positive sides of the batteries but that’s about it thus far.
I’m assuming I’ll need to double stack the nickel strips for the series connections but don’t seem to have much luck with getting a good spot weld (for double stacked strips only). I’m running 2 x 3s 4AH 40C zippy lipos in parallel so I should have plenty of amps to draw. My testing thus far has forced me to go rather high on the MS (10+) to get a decent weld and no real luck on double stack.
Any suggestions for a different orientation? Nickel Strip usage? Spot Weld Suggestions?
Edit: 1.5mm to .15mm correction
