Damn, so no verification of whether this layout would work?

I donā€™t think so

Maybe if you get creative and remove some of the enclosure internal plastic bits

I have the enclosure on hand but I was hoping you would know from the time you gutted the enclosure, Iā€™d hate to remove all the supports for it to not work, but thanks for taking a look I appreciate it!

Last time I removed all the entarnal plastic it didnā€™t effect the integrity of the enclosureā€¦like at all. I think the internal plastic is more there to keep the battery from sliding around

Hi, you seem to really know your way around meepoā€™s. I was thinking of building my own meepo v3 battery from 21700 cells, 10s3p. As far as battery building im a complete novice, it should probably fit inside the regular enclosure if i cut away some of the plastic junk like you have done above. Can i ask which BMSā€™s you use, or similar ones (Iā€™m in the UK), and Iā€™m wondering if everything on the board works normally with custom batteries, ie regen braking, battery % indicator. Thanks

Iā€™ve never tried to fit 10s3p into a meepo enclosure, but if 10s4p 18650 fits with a bit of a gasket, 21700s should also. I would recomend using a daly 10s bms and bypassing it for charge only. Everything else, as long as you wire it up correctly will work as it is intended too.

Triple stack 21700ā€™s would be thiccccc. I use an extra 5mm of foam on a normal 10S2P double stack with 21700ā€™s already to keep things from getting to compressed w/o padding.

brilliant, thank you

#31

I was thinking of cutting away all of the excess plastic so hopefully that would make room for an extra 10 cells, do you think i could get away with it without triple stacking?

#32

whatā€™s the advantage of bypassing the bms for discharge, doesnt it offer more protection if not bypassed?

#33

You could make it possible. If you cut out all the internal supports, built the pack staggered, and used a thick spacer. But itā€™s not going to be ideal. This enclosure will fit 10S3P 21700 fairy well, although also a little shallow for 21700 stacked
