Any reason you have the wires offset to the bottom?

yeah just enclosure design means that its easiest to do it like this (the wall separating the p groups is taller at one end)

Do you understand the limitations this brings?

I would have flipped the curves to face the other way so the solder joints were closer to the middle. This would not have used any more room up in the encloser

Unless the deck is flat at the bottom, the space between the walls and the deck might be the same everywhere, so it wouldn’t matter.

I’m putting a 16s6p in a tiny 18650 double stack eboosted enclosure and theres nothing you guys can do to stop me!!

So since you can’t stop me, how about you help me. How should I go about the at least 1in gasket/whateverucallit around the enclosure?

I want something that can keep a good amount of water out and that will not get compressed completely when you bolt it down.

Im considering using hex standoffs that go through a thick ass weather strip.

Thoughts?

This is 12S6P P42A in the same enclosure. You might struggle a bit with fitting16S unless you’re too mounting the esc.

The pic looks like 16s4p… bro I promise whatever gain you have from going to 16s will seem minuscule to the amount of headache this battery will give while you are building it, and worrying about it after you have built it.

Issue is the whole drivetrain is geared for 16s

There might be a better way. Try making your 4p groups with 4 cells in a square shape. Double stack. This way you can fit 3 in a row and go 15s. This will also reduce the size of your bms

Or you can still go 16s but you will have one odd group, as a pose to many odd groups

Hmm this is a better way. The issue is I already made 16 flat 4p groups. I have to weigh my options…

Nope, thank god. But the glue I used is too strong and I will not be trying to remove them from eachother. The pgroups in the photo are the ones in question. So just Glue, fishpaper, and o-rings
