YAY! Almost finished my scooter for Project: Underglow. (Will be published soon) I just need to drill a hole here...(grabs battery drill, clips in battery)...5mm bit......about there......and drill. Bugger. Battery flat. AGAIN. I was fed up. It was 2:30 in the morning. So I did this real quick hack to my drill. AND took photos :) just to show you'se mob.
It basically involves tapping into the 12V input to the speed controller, which would normally be fed by the crappy battery they give you. Sure, you can re-pack them with some big Ni-MH's, but I'm poor at the moment (around A$95 to repack a pack here in oz). So I decided to just hook it to a big SLA, which will give me some juicy current.
*Drill for longer (higher capacity battery)
*more torque (SLA has higher surge current capacity)
*Lighter (only lifting an 800 gram drill, not an 800 gram drill AND a 2.2Kg battery)
*Cord hanging out back (I can live with that)
So lets get started!!!!!
