Download Free 3D Model 4s10p 18650 battery holder for 14.4 volt with 1/4 inch bolt holes and tab slots 3D Print Model

Summary
This is a 4s10p, 18650 battery holder for a 12 volts system (with a low voltage cutout and a DC-DC buck). Nominal voltage of 14.4 with a high of 16.8 volts. It holds 40, 18mm cells snugly.
I added a 1/4 inch bolt hole to bind everything together, mount to a case.
One of each file should be printed to get the tabbing and alignment correct. They’re labeled top and bottom, but they could be used the other way–top as bottom and bottom as top (or left side right side, etc).
Each staggered row should be tabbed down the middle with cells alternating anode – cathode – anode – cathode (in series) and bridged over the tabbing slots to the next row with the cells aligned the same as the previous (in parallel). If you don’t understand how this works, study up.
Built for my portable solar kit.
