Anyone make a 39 cell 21700 case for ebike battery
My ebike's battery is getting tired and it's time to get a new one. I was just going to buy from the manufacturer cause the amount I would save building my own 18650 pack is not worth it. But I recently learned that Samsung 58E 21700 cells can be had for half the price of the the 35Es that would be equivalent to what's already in my pack, have higher discharge rate and more capacity obviously.
I'm content with the with the capacity I currently have and so building a pack with only 39 cells instead of the standard 52 for 48v packs would be more than enough. I don't wanna design and print my own box, I'd prefer the space saving of a smaller case, and I'm weary of the structural integrity of partially filling a case.
Has anyone seen a box designed for 39 cells in the wild?
