How much does it weigh? Thats a pretty long run time. My son is outgrowing his powerwheels. I need to start a project in building him one. Mod the one to run 18V which makes a difference.

Hi, The kart weighs about 35kg. The batteries are 12kg (3x 12v 12 Ah lead acid) and the motor weighs c5kg (36v 500W). Whilst the kart is not particularly light, it is robust and has pretty rapid acceleration. You mentioned the run time; this worked out to be much longer in practice than theoretical calculations would have you believe. If the kart was driven flat out constantly then run time would be a lot less (c40mins). After extensive testing we've found that kids don't drive flat out all the time and gain a bit of charge back through the regenerative braking system when they slow up - this gives the much longer 'real world' run times. You could easily build the kart with a different voltage system - just watch out for the cable spec to make sure that it can handle the expected peak current. Let us know how you get on.
