Has anyone here tried our CBP 650 2/3AA cells at www.cheapbatterypacks.com

They would be much lighter than the 2/3A cells that you are using now and still are good up to 15 amps or so. I think you guys are only pulling like 5 amps in these little micro cars. They might be just the ticket. They would fit great as double flat pack. You could use up to 8 cells and still be around the same weight as the original AA cells that come with the micro. They are also very inexpensive at $1.25 each. Just wanted to see if you guys are using them. The duration would be less than the 1050-1100 mah packs you are using now, but for the racers I dont think that would matter.

Best Regards,
