Notice he has a CC and 6/8v batteries all this adds up to about 350 pounds less than a steel frame cart with 8/6v. The reduction in weight has boosted his performance and extended his run time. Your results may vary. |

Tires: Some 23" tires weigh less than some 22" tires. If you are just looking for speed (and range), get tires with road type tread patterns. If you need off-road traction, look for high pressure tires with aggressive treads. (Tires with max inflation pressures below 10 PSI tend to limit top speed) Going from 22" to 23" tires will up the speed by about 4% and reduce torque by about 4%. Pack voltage: Upping to 48V will up both speed and torque up to about 1/3, so the 4% torque loss by going to 23" tires will be more than offset by the increased pack voltage. 6 x 8V vs 8 x 6V: Top speed will be close to the same, but 8 X 6V will be a bit slower because rolling resistance is directly proportional to weigh and eight batteries weigh more than six batteries. Same with acceleration. Range: You are already running a high capacity 36V battery pack and my charts are based on a standard capacity 36V pack, but some useful information can still be gleaned from them. You existing 251AH battery has about 11.6% more range than the standard 225AH 36V pack, so you'll will have to use 190AH 8V batteries to break even. The highest AH 8V batteries commonly found are Trojan Ranger 160 at 204AH, which would give you about 8.6% more range than what your existing batteries did when they were new. To get more range than that, you will have to go with a 8 x 6V pack (or 7 x 6V pack). |

Re: 36v to 48v conversion recommendations
I went to 48 volts (6 Trojan T-875's) the Alltrax 48500 controller, SD reversing contactor, 400 amp solenoid, 2 ga cables and 22" off road tires and I run 30 MPH and I haven't found a hill that even strains the cart. Like Dirtpit I believe it would flip before stopping. I do have an aftermarket motor that I am not certain but have been told it is the Raptor. Scotty can set you up so you leave your buddy in the dust.
