Thank you for your very fast reply.

Alright, max size of the box would be 140 mm x 200 mm x 300mm but really max ( with BMS, isolation foam, cables, plugs,...etc).

For the Weight: no real limitation.
Power : 72V 40Ah (or more) 3000W would be perfect.
Speed limitation : (i have a controller that can be setted to limit the max speed).

What i have most struggle with is the width since 140 mm is quite narrow.

I am trying to find the same cells!! ... did you find a solution ?
