Re: Voltage increase & Gear Ratio decrease effects on Torque
Mike, that is good to hear. Did you try the 72 volts prior to rebanding or after? I got my two new T-105 batteries on yesterday evening a rode about 7 miles in torque mode at 48v. Power was good, speed was comparable to speed mode at 36 volts. I got a good charge on all 8 batteries last night a will go for a ride later. I'll GPS this weekend in both modes. Motor was hot last night, I checked 30 mins after returning and I could hold my hand on there for 5 seconds, but it had been going full speed most of the way.

Re: Voltage increase & Gear Ratio decrease effects on Torque
OK, 48 volt conversion complete and the numbers are: Torque mode- 24 mph & Speed mode- 30 mph. The speed took a while to top out but, it basically ranged 29.5 to 30.5 in speed mode on flat ground, with a max speed at 32.8 on a slight downhill. So, the speed moved from 18-24mph in torque mode and from 26-30 mph in speed mode. The only thing different with cart was I put the top back on so, that may have slowed me a little. It appears I didn't have the horsepower to turn the 7400 rpms in speed, it was more like 6400 rpm. Anyway, the question now is....8:1 gears = mph??? Torque??? Any opinions welcome.

Re: Voltage increase & Gear Ratio decrease effects on Torque
Finally got the 8:1 gears in and the rpms are back to 36v rpms (around 5000rpm) in speed mode. So, I think the difference in the increase in torque from voltage increase (36v-48v) is washed out by the decrease in torque from dropping the gears down. Speed is up though....34-35mph, so it was all worth it. I just got to ride the cart this afternoon for a minute, I'll do some more testing later this week.

Re: Voltage increase & Gear Ratio decrease effects on Torque
Yeah, I cleaned my F/R real good and adjusted my Alltrax back to linear instead of S-Curve and got the topend up to 37.9mph. I've since switched to a PQ Motor and have topped out at 50.2mph. This setup is for racing and not daily driving, but I'm trying to see how fast I can go! Will be switching to cranking type batts for high amps and will be going with a higher amp controller to let the current flow. The batts will drop my weight considerably and raise my speed. I think every 100lbs is equal to about 3 mph in speed.

Mine pulls 50 amps at 30 mph with a 72 V pack. Wind resistance starts kicking in pretty good at 30 so I imagine the amps will start climbing above that speed. I need 8:1 or 6:1 gears to keep my motor in one piece though. |

There are some cool Youtube electric racers in link Chevy Nova, etc bodies. They use some like of special batteries I think. |
