36V vs 48v

passthru · 10-28-2014, 07:35 AM

I'm sure you see this question regular but what are the real improvements you get from a 36 to 48? I would be using it at the deer lease with hilly terrain and rougher rocky two track "roads". It's over 2 miles to my hunting area from camp.

The higher voltage produces more torque and uses less amperage.

So if it's like a trolling motor you get longer run time and everything runs cooler causing less issues with wires and circuits?

Yes, exactly.

Hey ScottyB my neighbor that I helped with the transplant in the CC,... 48v system running a 36v motor. He loves it, btw. He put new batteries on it, and not getting about two hours of run time. What do you think?

Battery pack should give 100 minutes of run time.
Short run time can be a result of high amperage draw (motor problem) or weak or small batteries.

I told him to upgrade his wires,.... also I thought new batteries needed training, so to speak.

thanks again

Well if I bought a 36v how much would be involved with up grading it to 48v? How inexpensive would the original purchase need to be to make it feasible? For a 5 or 6 mile round trip will a 36v system work until I could accumulate the parts to upgrade?

Batteries are 75% of their capacity when new. It takes up to 50 recharge cycles to reach 100%. The importance of battery & conductor size & quality cannot be understated when it comes to performance.

You could spend $1200 converting to 48v operation. You would need: controller. solenoid, cables, F&R (some models, charger, and 48v worth of batteries. A 36v cart should make a 5-6 mile trip if the batteries are good but, there are a lot of unknown variables in the question which can effect your results.

I agree with ScottyB 100% on this one. Well, first off, ScottyB has way more experience with this that me and my one 48-V TXT hunting cart. However, I will say that when I purchased my original cart, it was custom built as a 48-V hunting cart. It had 6, 8-V batteries and a heavy duty F\R manual switch. In the first 5 years of ownership, I probably replaced the manual F\R switch twice, and battery cables twice. But, when I upgraded to new Trojan's 8, 6-V and replaced the battery wires with new ones, again my heavy duty F\R switch fried. So, I made the upgrade to ScottyB's Super Duty Reversing Contactor and "fried" F\R switches are a thing of the past, plus pushing a nice little button is way easier than chunking on that F\R switch. BTW, on a nice day here in SW Pa., on our rolling hills (not going up 'n down our mountain hills) I can get about 12 miles on a full charge. Prior to the battery upgrade, F\R switch upgrade, and the cable upgrade, my best distance would be 8 miles. And that was on "dry" days, not getting stuck in any mud, and of course....no mountain up hills.

FWIW
