AW is actually a guy on the candle power forums named Andrew. He buys Panasonic and Samsung batteries(probably others too) and repacks them with his logo - you can order from the Candlepower forums and he will ship to you - he has had some issues with companies not wanting to ship batteries anymore, so not sure if he will ship to South-Africa.
Since he has started with his little project the market has exploded with clones and copies - all his batteries have a PCB (Protected) so if you ever see an unprotected AW IMR battery, it is probably not AW. Doesn't mean you got a bad battery though - depends on what they used.
I would recommend just getting a good brand name IMR battery than can deliver 10Amps or more - check the candlepower forums for various tests done on a whole range of batteries
But if you have your mind set on AW IMR batteries you can order them from Andrew here:
