battery recharging

,,, it runs at a slightly different voltage (3 vs. 3.6). ...

That would represent a 20% increase in input voltage, not a trivial amount. I wouldn't take a chance unless Aimpoint specifically stated the T-1 can tolerate that increase in voltage.

Many times devices optimized for battery operation are relatively intolerant of increased voltage. Most devices will tolerate a 10% increase, but more may be pushing it...

LiFe chemistry is LiFePO4, and is a non-combusting lithium chemistry rechargeable battery. It can vent, but it does not vent with flame. They tend to have lower charge capacity, and are usually 3.0v in a cr123 format. I use them a lot in my lights. Much cheaper in the long run, especially with an EDC light than running primaries, and less charging-mistake risks than a traditional Li-ion.

I just ordered from Goal Zero, don't have the stuff yet but I would be happy to share my experience one it arrives!

Yes please do! I could use more data on their stuff

Well I recently got an email from SF that it looks like they are selling rechargeable batteries and chargers now so maybe exactly what I'm looking for.

Also looking a little closer it seems that a lot of the solar panels and chargers just use a 12v DC car lighter type connection. So would something like the 123 charger above and the following be a decent combination?

Do I need a charge controller?
