I’m still hesitating on the the battery size, 10S8P or 10S10P li-ion. Guess that will depend on how many cells I can fit in this enclosure battery box.
@Blasto Here’s another waterproof box option. I’ve got the 7" & 11" boxes on my board. They have nice thick rubber feet on the bottom for built in vibration reduction.
Ya those cells look ultra sketch, got them from my ebike buddy, price was right. They actually have a clear shrink on them. Worse case, they are shit and i’ll make another pack.
it is to help prevent the high voltage path of the spot welder to jump across the electrodes. I want the path of least resistance to be through each piece that I am spot welding.
in this config without a hole, the path of least resistance is on the surface of the nickel plate.
now what i am trying to achieve with the holes, is to make sure the current path goes through to the other part that I am trying to spot weld.
I’ve been getting a better bond when I do this, it’s a real PITA but I think it is worth it.
manufactured cells have this air gap for the same exact purpose
Yes, it would be better if i had a slot shape punch, but i don’t and i didn’t feel like nibbling a slot. So a single hole punch will be good enough… we’ll see
Mounted my miniature vescx box, i was able to use the existing truck holes to mount my rubber standoffs. @trampa your sensor leads are really short, they need a good extra 100mm to do a nice loop to the box
You can mount your VESCs directly behind the motor casing (in between the two motors). We pre-drilled some holes…
Short wires, low losses, no movement in cables. Motor and sensor cables want to be as short as possible.
