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...

I would be careful getting a 12v inverter and trying to run it off of 24V. You might let all the magic smoke out of those electronic components that do the inverting.

There are 24V inverters made, and I did a quick search on Google's Froogle search and there are a bunch out there, presumably for marine applications since those systems tend to run off of 24 volts rather than 12.

Addnig a third battery to the chair is a good idea, but then you either use the third battery by itself for the inverter, or put it in parallel with one of the batteries. The downside there is that one battery will always be more charged than the other, forcing the other battery to work harder (discharge deeper) and have a shorter life.

On the other hand you could get a tiny portable Honda generator and strap it on there and then you acn recharge your batteries while in motion and technically you have a hybrid powered chair!!!!
