With my rickshaws up for sale we are considering one last amusing project to help a friend.

I know someone who runs local club nights and would *love* something a bit different.

After a bit of pondering we are considering turning a Velocab flatbed into a party bike (mobile pa system).

I have all the audio gear and 12v inverter, however was wondering if anyone has every experimented powering higher-drain things from leisure or car batteries?

The rickshaws will mostly be hovering near a local club, so an idea was to use several car batteries and switch them out when required.

Any thoughts?
