- 1. Lithium AAA's will over power your GoPro as they are 1.5v not 1.2v. The GoPro cannot handle the extra voltage and will turn off prematurely, usually in 5 seconds.
UPDATE - Some GoPro's seem to handle Lithium ok especially in very cold weather, but the above rechargables are the bee's knee. Also the later model GoPros appear to handle Lithiums better than the older ones.
The charger i use is a Power Tech Plus but there are many others similar with a 20 - 30 min full charge time.
