36v to 48v question

Waverider969 · 07-26-2013, 02:56 PM

Yeah kinda stinks they don't have 36v cores in stock. I'd be buying one now. Figure at this point ill upgrade and see how the clunker does. I was getting around 17mph bone stock on iPhone GPS. My 10" tires are fairly light. The back seat worries me a bit since that one is not so light.

Any opinions about batteries. I have a wholesale account with Interstate. Anyone ever used Interstate 8v batteries?

Guy at plum quick told me to stay away from them and like every other industry pro I've talked to he highly recommended Trojans.

Going from 36V to 48V is a 25% increase in power, you should roughly see the same increase in speed and torque. I said roughly. Adding a built (PQ) 36V motor will keep it rolling when you add the bigger tires, lift, rear seat and HD leaf springs (all = weight). Agreed, solenoid you should change to 48V. V-glide and resistors will be your weak link when upgrading to 48V with 4ga cables. V-glide is tight for space on the cable side and the wiper contacts may arc a bit more. Resistors will get hotter, faster, when at less than full speed. May burnout/break at some point. I haven't had any issue, but I either go full pedal or coast, to avoid resistor "glow", when possible. After you do all that and still have the need for more speed/torque, you're done. You then will need to go with a controller setup (or a different built motor). At least you will have the 48V batteries. Probably didn't help you at all, but thought I'd throw this out there. As someone once told me, "You're only limited by your wife or your wallet!". Have fun. Good carting.

Do the conversion right the first time. It needs to be converted to solid state. Those resistor coils WILL NOT hold up. Save yourself a fire and call Scottyb at www.cartsunlimited.net

As far as the interstate batteries - I have use countess sets on builds and have only had to ever replace 1 battery.
