18650 bicycle support

Holder for 18650 on a bicycle battery pack of 388x111x75.

Mine got defective after one year of use and after releasing weld batteries, many of them were useful.

So I decided to make a support of 3x18650 to fit 40 of them on the original metal case, using metal springs from amazon either aliexpress.

And in case of need replace them,

Sizes are dimensions are quite accurated to fit metal case and to force battery not to move while cycling.
