I’m welding my batteries ready for when mine arrives, but I could really do with some help/advice.
My current plan is spot welding 1x 12mm by 0.15mm nickel strip across 6 cells on each side. Then solder 5 12 awg silicone cables between two new strips, then spot weld those strips on top of the first ones, linking two packs, then repeating for all the packs. This theoretically minimises the heat going to the cells but still gives the strength of the silicone cables. These would then make a U shape over the battery dividers.
Any issues/problems with this before I start?
My second area of concern is battery insulation. I have some 150mm heatshrink I will double wrap each pack with, should I also use double sided foam tape to attach to the battery enclosure? Or will resting on foam pads be good enough? Should I use fish paper instead?
