So, which cells did you use in the end ?
A123 20Ah and I think B grade in 32s2p configurationHillhater said:So, which cells did you use in the end ?

Motor is the same and it seems I can not get more out of it because of the fact, that it is 48V motor and 700A phase current to motor is max. I need to upgrade to 96V motor that has twice the torque for the same amout of current
Anyway here is the video also: http://bit.ly/1WgAztt
In the video I had already raced 6 laps, thats why controller and motor temp are so high.

That wouldn't make sense because they both have the same power. Yeah, twice torque, but half the rpm. Remember, power = rpm x torque. If you want more power, raise the rpm (I think the 6000 is limit for rotor, maybe you could do some custom work to reinforce it), and gear down. That's the only way, along with better cooling.

Practically on par with some of the top F1 race teams....
....and better than most everything else on a race track !
Thanks for posting.
.... Did i miss the lap timer ?

The setup I drove was with 2 zero bricks and a 75-7 and a size 4 I had no gears jus 1 speed it was geared for just under 80mph and would lay rubber at will in the low speed corners. Run time is decent I was not on a track but my friend Doug is racing it for fun against gas karts. Yes when I say shifter that's the chassis which has all wheel brakes and a big rear axle and set up for fast racing with the frame that will support the 54hp motor and 80lbs of batteries.Hillhater said:Arlo1 said:I have Driven a shifter with a 75-7 Zero motor it rips hard! ...!
I assume You mean a "shifter" chassis ...but not with a gearbox ?
How much battery/run time did it have ?
