Well, mostly just heat-shrinking funs. Anyway, this took more time than soldering the 240 or so cells… who knew?
I’m using the 100mm diameter Turnigy tubing from HobbyKing, and even with the $30 shipping it was cheaper than industrial suppliers. I ran some braid on top of the solders to beef up the ampacity (my favorite made-up EE word) but I think I screwed up. I want to pull one of the conductors off the opposite side, so the cells stay balanced. No worries, that’s an easy change. I think.
Here”s one 10-cell, 3.4V 23AH module:
The finished pile:
…and likely the configuration I’ll be putting together for my battery trays – one on the bottom and one in the belly, just like the CALBs I’m running now, but smaller:
update: Here’s the pack with the pos/neg leads swapped to opposite sides:
Here’s what the CALBs look like now:
So, now, what to do with the CALBs? Mayhap, a little boat project?
