[NSRCA-discussion] A123 batteries

[Dean Pappas]

Hi Keith,
What was the part number on that DeWalt pack?
Did you buy it at a retail outlet?
The guys at Home Depot looked at me funny when I asked if they were going to stock extra battery packs.
Thanks,
Dean

I bought a DeWalt 10-cell pack and have made two 3S and one 4S pack for my Mini-Inspire. They are definately heavier than Lipo per cell, and larger (about the size of a C-cell).  If guys are barely making weight with LiPo's, then they won't make it with these cells since you need to use two 10S packs, their capacity is 2400Mah.  Each cell is about 70 grams. 
 
However. . . . I like that the A123's are much more robust than LiPo's.  You can store them at full charge, discharge them to 5%, draw mega amps, charge at mega amps, and not worry about them quitting at 20 cycles because you didn't know of some stupid limitation.  Oh yeah, the whole "don't vent with flames" thing attracted me too!!
