The question I asked was: "Would this work as a rechargeable battery for a DMG:

I think you can run a DMG on this low of voltage but will it also run it with a back light in it?

Thanks,

I'm not 100% sure about that running it but for 20 ish$ you could probably get a much higher capacity battery for it

 

[zaxxon]

example?
EDIT: not trying to be a smart ass or anything, just wondering

 

[superben51]

well there's this one that is a little bit higher capacity but much cheaper....smart-ass KIDDING

Or this one that is a little bit thicker

I just measured the space I have to work with and either of those would work, but that's where the problem lies I'm not sure if it can work on that low of voltage with a backlight.

 

[Bibin]

A DMG can run fine on 3V or higher.

 

[superben51]

and the backlight is just a really big LED am I wrong? so it should run fine off 3.7 volts also.

 

[Mister Nickels]

Why do you want rechargeable batteries in a DMG? The 4 AA's lasted quite awhile with my old one, does the backlight really suck up that much juice?

 

[zaxxon]

It's not that the backlight sucks up juice but rather that I just want to be able to recharge it instead of replacing the batteries.

 

[superben51]

I can kinda see where he is going with this. Spend 10$ on battery/pcb and then never have to buy pack of AA's (which are can be up to 5$).

 

[zaxxon]

Yah that and I also just wanted to try this, it seems pretty cool.

Also i'm using this charger:
