Yeah I was going to add on the that post I think since the Battery works 100% a parallel kit is perfect.
I actually have 11 4Ah lipo cells I wasn’t planning on using but it’s the perfect thing the pair with a $10 CC CV module. An extra 130Wh would double the range. I’d like more like 20 miles range ish, but this will be a good test and I could just switch the battery out for a bigger one.
Also tire upgrade + 3d printed flight fins + and I might try to make urithane footpads for it.
Not sure why I posted it in the pictures thread. Please call out anything that seems off.
I tested wires for continuity before hot glueing them in. Used a credit card to smooth the glue lines this time.
Also left some slack in the wires where they’re connected or bent around a corner.
Lol those batteries are huge 
I had to order 240mm flat diameter PVC shrink tube to fit around each 5S! 
So it should be holding 2.5-3ah. I’d give it pretty good bill of health. Download ponewheel and onewave to get access to individual cell level voltages. I’d expect maybe one cell to be lagging a little, a 24hr charge should help balance it. Good score, now get to modding it.
Making progress:
Still looking good? I used the Sunkko 737g, could only do 2p/70% without blowing the fuse. The test with a cutter blade and nickel looked good with these settings, small welding points but no burn marks on top and a visible ring on the underside of the blade. Could not tear it apart either without ripping the nickel. I compensated the size of the welds with quantity (obviously :D)
What’s going on with the pvc wrap around those cells? You may want better insulation between p-groups
Oh, thats Kapton. The battery will be a flat pack, P-groups will only have contact on the sides with the fishpaper and addictionally divided by a TPU printed spacer. After I soldered the serial connection I’ll also shrinkwrap each group, should be sufficient isolation from each other 
I’m familiar with kapton. My comment was more in regards to the shrink wrap not completely covering cell. But it’s good that you plan to use fish paper. I hadn’t noticed it in the pic. My bad!
Its a bit unusual, I know 
I’m reusing cells from two NESE compression pack batteries and for those I had cut the shrink at the negative side to prevent cutting pieces of it when pushing them in
balance wires looking niooooce
How not to build batteries
uuu that is not looking nice
that’s a guaranteed fire ball
I would be worried about series current running through these spots
Edit: if the tabs from your cells ran all the way to the other side of your busbar strip it would be a lot better
For piece of mind i think that is the safest bet
