Ebay Dewalt 36V packs typically. 10 cells for ~$100
i have a TP 1010C thats nice, but an astro 109 works really well, ot even just getting a lipodapter (Dapter) to charge A123s on a lipo or NIMH charger is a good way as well.
I am pretty sure a 5s2p pack last you 15 mins geared around 40mph.
I get over 30mins with 7s2p pack, and that's only 4 extra cells, and a Neu 1512.

Do you know if the Superbrain 989 can charge A123 batteries?
