So I've had my joye 510 for a couple weeks and I love it. The only thing I don't love is the battery life. I did some research and found this was a common complaint with any 510. I am looking into buying a batt with ext. Batt life. Not really sure if this is the best option. Is the ext batt worth it? Is it that much better than a standard 510 batt? Should I just buy a pcc? Anyone have any experience with this?
