Sorry if this has been beaten to death, but I can't find a definitive answer. What, besides a slightly higher cost of entry, am I losing by going with the 2900mah batt? I have used both, in my Grande, and they seem to hit my LR atties the same. So, I'm inclined to stick with the higher run-time. Am I really losing anything here?

The 2900mah will colapse the spring more. Running the chance of ruining the spring and having to send it to Dr. Rob for repairs. So I have been reading from the Reo pros here. I have the Mini myself. My post is just an observation of past posts.

Huh, just noticed that it is about 1/4" longer than the IMR.... good catch.

Cisco discussed his reasoning on another forum.... I agree 100%... ;)


It is true that a decent Li-ion (in the larger sizes) will output enough current to run any e-cig properly. IMR's will output more consistent current across the discharge cycle, Li-ion tend to drop off faster then IMR's, the reason the first 10-20% of the discharge cycle on a Li-ion is hotter then the remainder. If your boosting and or regulating you wont notice a drop off in output, so with an IMR you will sacrifice vape time over a Li-ion, for that configuration Li-ion will serve you best.

Personally I prefer IMR's because of the safety factor that Li-ion do not have, I am willing to sacrifice vape time for added safety and consistent unregulated current output. IMR's are a safer chemistry in the fact that if they vent, they only vent with gas not with gas/flames, IMR's do not require protection circuits and are designed to be the safer alternative in stacked battery configurations similar to LifePo4 ( true LifePo4 Chemistry is 3.2v nominal, LifePo4 do not come in 3.7v, it is a chemistry limitation. If you see a LifePo4 advertised as a 3.7v cell, its more then likely LiPo chemistry)
