I am tired of buying energizer lithium's to run my photon xt. Yes I know I can buy cheaper batteries, but their life isn't as long so it defeats the purpose for me...
Anyway I thought I'd share it with you.
Started thinking about an external battery pack that I could use rechargeables on with extended battery life. I already have a bunch of 18650's laying around for the IR illuminator.
Nothing fancy but working. Going to mount it to a weaver/picatinny adapter so it can connect to the rail on the side of the scope. Haven't gotten that part in yet. Anyway drop it in and powers it just fine. Let it run for over an hours last night. Haven't field tested it yet, hopefully this evening if the pigs show back up.
