36V to 48V conversion piecemeal

thetoddjohnson

Hi all. I have a 36V '94 DS that is essentially stock. I plan to convert it to 48V next time I replace the batteries. I've already upgraded the FNR switch, and I've got a new set of 2ga cables ready to be installed when I replace the batteries. The solenoid is acting funny so I'm going to replace it. I'm thinking about just biting the bullet and getting ScottyB's conversion kit now. My question is this: Since my 36V pack still has some life (probably 2 more years) would there be any reason why I would not want to do the conversion and continue to run on a 36V pack? I don't see any downside to doing this. Am I missing something? I plan to keep the stock motor.

The one plus to upgrading, even staying stock, is that increase in voltage is like increasing the horsepower of an engine. At 48v the stock motor will have greater torque and power and you will gain slightly on capacity due to the motor working less. I'll be in the same boat as you way down the road as I just bought batteries, but I'm new to carts, so I'm learning as I go. Had I known what I know now, I would have bought the 8v batteries and converted to 48v (I got this cart free with no batteries, but is my first cart).

There would be no downside to doing the conversion now and converting later. Think of it as "financing" the conversion by buying pieces as you go. Saves you from having to spend so much up front to do the conversion.

TJ---staying with the 36v pack after installing ScottyB's conversion kit is just fine. Just be sure to tell ScottyB that you are going to upgrade later to 48v. He will probably set you up with the 400 amp solenoid which works with both voltages so you only have to buy one. He will take care of you. Just tell him what you want to do now and in the future

Another idea might be to hunt around and find a couple of used 6v batteries on-the-cheap and "temporarily" mount them in the bag well just-for-now. That way you can run 48v off the mark. If there's only a couple years life left in your current batts - then a couple good used batts might just last a couple years in temporary service. If you route the battery wires by drilling holes thru the back inspection panel - then when you switch to 8v; just replace the panel (they are cheap enough for DS).

Of course there's no guarantees the used batts will get you two years...which is why you should buy them cheap (and you'll need to spring for a 48v charger) - but it might be a more affordable way to get further along in your conversion.

Thats a great idea! Thanks.

Would a single 12v play nicely with the six 6V batteries, or is mixing voltages within the same bank a no no?

No- they have different charging needs. Don't mix 6 and 12v batteries
