when I'm cruising up a hill I keep an eye on the amps and pedal if they go too high. a 36 volt 20 ah on a skateboard? what happens when you need to bail off the board and it crashes into a curb or someones leg?
sorry to be negative just making sure you've thought of the danger of a heavy board

The reason why you needed 20ah is because most low end packs can only do 2C max without self-destructing quickly, and the less you hit that max, the longer it will last.
This is probably the best deal in a lightweight 48V 10ah 5C pack:

I'm almost considering reselling my 20ah 18650 pack and getting that instead.
