So Ive switched from a 4x 18650 mod to the dual 21700 geekvape blade. My mah/battery life is pretty close with the dual samsung 40t's which are 4000mah/30a each but would like a little more longevity ( I hate changing batteries mid day and dont want to carry spares to work) Im running a pretty mild setup in my asgard rda..... small gauged dual claptons @ .43ohm/45w / 4.4v / pulling 10amps. So I think im safe to assume the 5000mah 21700's would holdup well enough even though they are only rated for 10a continuous discharge each, Im only pulling 10amps and running 2 batteries in the blade so wanted to give a pair of the 5000mah 21700s a try. Should I go with the samsung 50e's, the Imren 4800mah's, or the efest 5000mah 10a's? Do you think they would last noticeably longer than my samsung 40t 4000mah batteries im using now?
