We need to find a reasonably priced source for the
17500 li-ion cells like these on that site.(scroll down to the 17500)
They are 17mm dia. by 50mm long, slightly larger diameter than a AA batt(14mm dia.) but have a decent mah rating but only 500 charge cycles but still thats a lot of racing.
The 14500 are the same size as AA batts with a mah rating of 620 but I'd prefer the slightly larger batts with the higher mah rating just for the longer run time.
Those batts on that site are overseas so I'm looking for a source here in the states.I encourage everyone to look for a good source of these batts.
I do have some 17500 batts coming but they wont be here for atleast two weeks.
