i have the standard pink one in mine, but the battery life isnt sufficient with a rebuildable. what are you using to improve battery life?
I use the IMR 2000 mah flat top batteries from my old Lavatube in a pinch. Don't need them often, but they work just fine. FYI- I rebuild my heads too (2.0-2.2 ohms typ), vape at about 6 watts and my original pink battery is giving me about 24 hrs elapsed time.
It depends on the setup.
Provari and other VV/VW Devices: Panasonic CGR18650CH
Mech mods with SLR Coils (10-20Watts): Samsung INR1865020-R / MNKE IMR 18650 / AW IMR 18650 in that order
I prefer to stick with safe chemistry high drain batteries when possible, although the Panasonic and Samsung are not LiMn chemistry they have been tested to be close to as safe. I take great care of my gear and check my batteries often to avoid problems.
A better price on the Pannys. Free shipping and this is for a 2 pack!
