Re: Longtime lurker, first time poster
On to the electrical.
So I started with a Ryobi 18v lithium battery. The slim one. I opened the case and took out the guts. I got a project box from radio shack and in went the battery. I used a voltage regulator from RS to provide 12v for the taillight. The switch is from the main battery positive to the 18v front lamp and to the voltage regulator. The 4 pin and 2 pin connectors have been wired to the charging and testing leads that are in the original battery housing. I simply hook the wires to the battery box then plug the dummy case into my Ryobi charger. I found these little vents at Ace hardware and they look great in my opinion.
It is back yard engineering at it's finest! I am still fussing with how to mount this battery box. I know it is going to fit just under the tank. I am leaning towards metal zip ties at this moment...
