bigger motor and battery life

whisp

i have a new motor in my club car that's now a 16.5 hp 48 volt and have a new 400 amp controller...once i have new US batteries will the new motor cause my riding time to be less? i mean does the motor pull a lot more energy therefore giving you less time on the road??? if so how much less time?

In theory no if you do not accelerate at a greater rate or go any faster than you did before. In practice though you will get less run time.

i just put the pedal to the metal...not that these electric cars can go all that fast...30 max on a ful chg...but i guess your saying the larger motor will definately produce less road time even with new batteries. by road time is half of what it was 3 months ago...batteries are clean and i maintain them really well...but i bought the car 6 yrs old and bat's same age (swollen at sides) but it's been scootin along real good until recently...so, i'm installing new batteries tomorrow.

Short answer is YES. By slamming the pedal to the metal you are putting a lot more load or drain on the batteries with a larger motor. So if you went from say a 2 HP motor to 10 HP, you will in theory only get 1/5 of the road time. Distance wise just less than half the distance on a flat level smooth surface.

Or look at it this way ,
Lets say the store is 7.5 miles away
If it took U 1 hours to get to the store and back on the old motor doing 15 mph.
But it now takes only 30 minutes (1/2) the time with the new motor doing 30 mph.

The same amount of battery is used, the same distance is covered, but peddle time is cut in half .

So YES what "sunking" said

and don't sell yourself short 30 mph on a cart is D%^&*m good ,
Good JOB
