Can I use an 18650 2500mah battery in a Grand or a 2900? I'm talking about protected ones. I notice the 2500mAh work although it compresses the spring pretty good because of the extended length.
It compresses the spring TOO much. The spring can't drop. So you get a short, the battery stays in contact and your REO gets fried!
Just don't do it, PLEASE!
If you already have an AW IMR 18650 then that would be perfect. Since you'll be using primarily LR atomizers/cartomizers on it. You might as well have the right battery to offer the power that's needed for them. I know it's an obvious response but, just putting it out there.
The MNKE IMR would also be a great choice and I'm surprised more people arent using these Batts there super !
The above post is a clicky. I guess beezer missed it.
