eBay, many online stores. Look for lifepo4 aa, or lifepo4 14500. Be sure they're the right size before buying! You have to rewire the battery tray to work with two instead of four batteries, but that's not difficult. Finding those 1600mah versions (like in the picture) is tricky, though. Most are lower capacity.
