This is more of a hopeful thinking question than a discussion, but I couldn't find any information elsewhere, so here goes. I have an L-rider robust that I like for the most part...EXCEPT THE DANG BATTERY LIFE. Right now the highest mah I can find on a 14500 battery is 750. I was wondering if there was a chance that an extender cap would be developed and the logistics of the whole situation. I don't mean so much so as an 18650 batt. But just something that has a better mah than 14500's. Thanks!
