Scroll down to the bottom and you'll find 150maH 1/3aaa NIMH batteries.
The ordering is kinda scary.. no online ordering; have to call 800 number which seems to be answered at a residence by some elderly lady. She seemed knowledgeable about order tho, like solder tabs or no tabs and shipping prices ($4 minimum flat fee). My credit card has an insurance protection plan against fraud but hopefully I won't need it.
When/if I get mine I'll let you know if there's any difference b/w these and the 120maH's sold in the tinyrc shop. If they really are 150maH that'd be a 25% gain in capacity vs the shop ones and a 300% gain vs the stock NiCd's.
Tinyrc, if these seem legit you could check on stocking these in the shop as well. This site is the only place I've found that carries these besides tgworks.com which recently shut down. More later...
