32700 Cell LiFePo4 4S3P Battery endcaps

thingiverse

This is an end cap designed to allow you to more easily build a 4S3P LiFePo4 battery from 32700 cells, to give a 12v 20Ah (depending on specific cell capacity used) battery which can be used instead of a sealed lead acid battery. I will use this for Ham Radio applications like a field station, but it can just as easily be used for a small solar accumulator. The holes are 32.6mm in diameter to give clearance when printing, and hold the negative end of LiitoKala 32700 cells snugly. The Nickel strip channels are 8mm wide and 2mm deep to take whatever nickel strip you want to use, as well as 1-2mm OD cable for balance leads.
