As for the speed controllers , one of these may do it if you don't stall the motors and under volt them a bit.http://www.technobots.co.uk/acatalog/On ... s_351.html 2 of tjhe bottom ones fo these would be more suited.

as for batteries, 3 of these would do nicely http://www.technobots.co.uk/acatalog/On ... H_484.html, ideally wou would want about 9 so you had 3 changes of batteries to keep your bot going through all fights. as for chargers, http://www.technobots.co.uk/acatalog/On ... rs_36.html 3 of the bottom chargers would charge those batteries nice and quickly.
