With nickel cells, as long as the heat can get out trickle charge current shouldnt be a problem correct? So as you increase the ratio of surface area to volume (decreasing overall size) it should handle a higher 'C' trickle charge. Same as how some tool LiFe packs are rated for many many C discharge, vs a large electric vehicle sized pack couldnt push out the same C discharge because of heat not being able to escape. --=20 Jonathan Hallameyer --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
