AVR-Chat

Thanks for the pointer, I just rang a local battery supplier, to buy a 3
cell AAA NiCad Pack in qty's of 100 I would be looking at ~$14 (far to
much) but I can get a single cell Lion Battery with 2AH rating for $6 in
100 qty more like it lol.

He said the price difference between an 0.8Ah and 2Ah was 50c so I am
now looking at Lion charger chips lol  The LTC4054-2.4 looks nice and
simple.

Regards,

Kat.
