I was under the impression that the MaH is only a guideline. I have been told that instead of high MaH numbers, it is more important to get "High Drain" batteries. I have 3 AW 18650 3.7v 2000 MaH batteries that , after a year of service, will not hold a charge well anymore. I am considering buying 3 3400 MaH batteries. I am weary of the effect it will have on my Provari. Would this be awesome, or just an enormous waste of money?
