Using drill batteries in robots

[jamesb]

which is what i did in the r2d2 project. its fine as long as you dont want too much current. we left donut tyre marks on the kitchen floor with these batts running 12v drills on a 30kg robot, so there is performance to be had.

how would you connect the drill batteries while they are still in the cases?

take the connectors out of the drill case and use them

i was wondering if some one could tell me, how many drill battery packs i should use for this set up:
4 12 v drill motors
they came with the batteries

but how many do i use?

thanks alex

I beleive that Push N Shove had a setup quite the same as that, and used 2 x 12v battery packs. One 12v pack per SIDE along with 1 Speed Controller per side.

for talon i disgarded the drill batteries and went for one 3.3Ah sanyo pack

[psycho_fling]

is it alright to chop the casing down a bit on the drill batteries?
i.e. keep the connector bit but cut the main housing off? it just the batteries wont fit otherwise in my robot

thanks alex
