Easy build self balancing electric skateboard

Step 40 Re-arrangement of components

I have found a better way to arrange the components (March 2011).

Use a thick board to mount the motors and wheels to that will not flex.
On top of this bolt a large size regular skateboard deck.
Mount batteries to underside of the skateboard deck, just outboard of the motors, which themselves should be as close to the wheel sprockets as you can get them.
If distance between top of wheels and skateboard deck is 3-4cm you will find the batteries can be fitted underneath. With suitably large (but not too large) wooden bump stops under each end of the deck you can arrange things such that the bump stops hit the ground before the batteries do - which would not be good for them.
Electronics now placed on top of skate deck in small housing. This as also makes them more easy to access.

Hi John,

Could you share me how to mount the batteries underneth ?

Thanks.

I had some spare angle brackets of the same type used to hold the wheels.

It is not a work of art but I bolted them together so they formed a Z shape, and bolted one flat edge up under the board, one of these at each end of the board. This forms a suspended support you can slide the battery onto.
With some additional bracketry underneath and tape, the batteries can be held steady under the board.

John,
Thanks for your response.
I'd like to see the pictures of battery, if you can sharing with me.
