48V Lithium conversion questions

[TMarshall]

Thanks guys, for all the good info. It’s definitely given me a lot to think about, as far as cart use and if it really fits my needs/lifestyle. I did pick up a new F/R contractor as that seems to be my first issue. Now to rewire all control wiring with new contractor and see about a test drive.

He certainly "might" be able to run with this controller (on paper anyways) ... if the controller is actually functional

If his controller is pooched and has to be replaced, I would certainly suggest upgrading to a higher amp rated controller for this heavy, work cart.

For my nearly identical cart, Alltrax suggested an SR 500 amp would work fine ... as would an SR 600 amp ... but the 600 amp might be overkill.

If the controller has to be replaced, I would certainly replace it with one with a built in cooling fan. I find my 600 amp Curtis tends to run hot and I live in a cool climate. With the Alltrax, a fan panel is included in the 500 and 600 amp models. In the lower amps models, the fan panel is optional.

Yeah....if I'm buying a new controller, going a little bigger is better.

I missed where he said it was damaged.. though he said he just wanted to reinstall it to clean up the wiring.

Everything is installed, damage unknown. I don’t know full status of controller yet. I’ve gotten forward movement of the wheels, but F/R contacts are not making and releasing like they are supposed to, and control wiring is iffy. Going to install new F/R contacts and completely redo control wiring, then see how controller does. And that’s if batteries are decent. It shows 50 volts, and didn’t budge when I got forward movement, so fingers crossed.
