Hi, microMerlin, actually, I’m already figure it out, connecting the batteries in series and parallel by myself using cables parts, since the single 18650 Battery files you used was already posted by vanepp before,
But I’m prefer use Battery.fzpz files I posted in Post #26, because I’m using similar parts in real life as same as the Battery.fzpz files visual, 
for me, its important the Wiring Diagram visualization that I use for teaching 7 y.o kids has similarity visual with real life parts I use when teaching, so the kids will not be stressed out quickly,
But, I really appreciate your effort to replying my request, I’m sorry if I’m waste your time and energy,
