OT inverting power from 24 volts (help, please!), (2 batteries in my wheelchair) Options

[Korijo]

I want to invert some power from my wheelchair. It has 2 12v batteries. It already converts 110v to charge them.

Here's what I want to do...

1) Power my video camera/charge the camera battery.

2) Run my electric lawn mower. (IMG:style_emoticons/default/wink.gif)

3) anything that needs 110v... (IMG:style_emoticons/default/idea.gif)


Anyone know what I need ? I dont know where to begin...

You can get an inverter fom radioshack that would normally be used on 12v car systems. I bet you could even get one on ebay for less. But, you may wish to add a third battery as I am not sure of the current draw. Here is a basic concept: Voltage inverters work by either exchanging amps for volts, or volts for amps. So If when charging your chair you are going from 110v to 24 0r 12v then I would bet you that the current coming out is large. If you wish to do the reverse it will take large current from your battery and convert it to a low amp/high voltage output (E=IR).

You may have a harder time finding a 24v converter, but you could just hook a 12v up to one battery.
