Olight's 2.4v battery put to a good use.

I've been using the new olight 5r usb rechargeable battery in a Peak El Capitan. These batteries are available online if you look. I got to say it's petty sweet. I get lumens close to a 3.7 li ion but with none of the overheating and almost as much runtime as a eneloop. In this testing phase I'm looking for damage from the crush but so far everything is good, however it's a future possibility. If this works out for the first time I can make a gift out of a peak flashlight nice and bright with a usb rechargeable battery.
