[EVDL List]

Re: [EVDL] Ranger Conversion Amps & Warm Motor Okay?

Dave, I'm afraid I'm missing a couple of vital pieces.
a) If you are pulling that many battery amps from
floodies, not good.
If you are talking controller amps to the motor,
you're going to be okay, especially if you're talking
about the 400-450 from a dead stop only, and not
constant.
The other thing is that the motors are made to really
heat up to the touch. They have insulation, and are
built to specs such that they can handle it.
Obviously, you haven't given us _specific_ temps, but
you never described it as "burning hot omigosh, OUCH!"
so I'm going to say it sounds like mine, which is 3200
lbs., and 8" armature.
peace,

Would you still drive your car if the tailpipe came out of the steering wheel? Are you saving any gas for your kids?
