Battery Building: Should these connectors work?


#1

Over the next week I’m going to be disassembling my 10S4P 18650 battery and rebuilding it similar to the way @chaka builds his with 3D printer cell holders and cell level fuses. As well as this, the battery is going to be built into 6 smaller packs (4x 2S4P, 2x 1S4P) that are connected together in series so that each pack is under 99Wh. This way I can easily pull the battery apart when I want to be able to take my board on a plane.

For connecting the power cables between each pack I’ve bought spade connectors (which will be insulated with heatshrink) as they’re a bit thinner than bullet connectors.

I’m then looking at using servo cable connectors for the balance cables.

What do you guys think, should these do the trick?


#2

Why not just use bullet connectors?


#3

I’m trying to minimize the thickness of the cables/connectors because because my current enclosure has limited extra room on the sides of the cells


#4

What’s the mp rating on those connectors?


#5

I’m unsure exactly but it says on the back that it’s designed for wire up to 6.8mm


#6

My bullet connectors from the same brand have been used to have 20 amps between 3 of them for my hubs from vescs. Not sure if that helps anyone :stuck_out_tongue:
