Misterjake i know Ernie is testing batteries out . Like with his lights he wants to handle the best products out there for the predator hunter. Not sure where he is at with them yet so hopefully he will chime in.
I'm assuming we're talking about 18650 batteries here ?
I scored a couple from Ernie yesterday, they're in the charger now.
At a glance, they're heavier than all my other 18650's and have a much larger + contact.
