I was planning to 3d print a enclosure for the Jet Spud 29" deck and noticed I don’t have a lot of room for the batteries… The Bestech HCX-D223V1 BMS and the two vesc’s (EScape) I want to use take quite some space:
I was planning to spot welder all 4p batteries using nickel plate strips (0.15 mm thickness and 10 mm width) and connecting all 4p batteries with each other in series using 10 awg wires. The problem is, I have to put 10 batteries in one row which means two batteries remain in the end that I will need to connect in a square formation as you can see here:
In green you can see the nickel plate strip connection (4p) and in black/red the connections in series I was thinking of. I would rather have something symmetrical but this is the only way I can realize this configuration for the jet spud. The enclosure will probably have a depth of around 50 mm because of the batteries.
Looking at the green square, is it ok to solder the 10 awg wire at any position on the nickel strip? For the 4 linear 4p connections I would solder the wire right in the middle but on the green squares it won’t be symmetrical. Do you think this can be a problem?
