Smile Mot-b2

Looking for a motor with more torque. I have a 2008 PDS 36 volt I little while back I upgraded the controller from stock to the XCT 400 with the large solenoid, 2 AWG wires and the cart with stock tires was getting 26 to 27 MPH on the GPS.
now I put on 205/65-10 tires and a 3 inch lift.

we take this cart a lot to our vacation place with rolling hills so I want more torque and going to the MOT-B2 looks to be the correct answer

will the XCT know a changed motors or will I have to make set up changes on the controller. and can I at this point also switch to 48 volts from 36

just by upgrading to 48v, which is the way to go, will get you 30% more torque right off the back.

You'll need to load the correct field map for the MOT-B2 that should be provided by your motor supplier or by emailing Alltrax.

And, YES, bumping to 48V at this time would be fine. You will love the extra voltage!

Your tires are 20.5" tall and might have fit without the lift.

It'll take about 14% more torque to go the same speed with the same weight on-board, so going to 48V (+33% in torque) will more than offset the torque loss of the taller tires.

Pedro, You sent me a PM, but your account isn't set up to accept PM's, so I cannot reply to it.

However, in a nutshell, you've got me mixed up with scottieb at Carts Unlimited.

johnnieB thank you I think I fixed the PM issue

Current setup 3 inch lift 20.5 inch tires

I have already installed the XCT400 controller from ScottyB thanks

what else:
MOT-B2 for hills and extra passengers
Charger, convert charger receptacle on cart to 48 volt (2 wire square Notch type or Triangle RXV type) and batteries

Batteries ill probably just get local.

Am I missing anything and what can I get from you

Thank You

You technically don't need to change the charge port. Yours can handle 48v just fine (it actually has beefier contacts than the 48v "triangle" one). Just order a 48v charger with the TXT "D-plug". Just be sure your charger only gets used on your cart. That could save you over $100 on the conversion.

There's nothing you can get from me except opinions, speculations or troubleshooting tips. I don't sell cart stuff or work on carts other than my own (and help a few friends)

Shipping cost more or less preclude getting batteries anywhere except locally.

The Mot-B2 running on 48V will very likely do the job.

Personally, I would have a 36V Powerwise D plug put on the 48V charger, but your circumstances may be different than mine.
