I just checked and the Razor Crazy Cart XL has a 36 Volt 12Ah battery pack so you could custom install a 36 Volt 1000 Watt motor without upgrading or changing the battery pack.

With a 1000 Watt motor the ride time with the original 12Ah battery pack would be less than with the original 500 watt motor though, so if you want it to have the same amount of ride time with a 1000 Watt motor then larger batteries would need to be installed.

Whether you use the original battery pack or upgrade to a larger one, the only parts other than the motor that are required is a 1000 Watt speed controller, and possibly a different length of chain. Any of our 36 Volt 1000 Watt controllers can be custom installed on a Razor Crazy cart XL and will work with any of our 36 Volt 1000 Watt motors.

The original power switch and throttle will work with our controllers and we can help with providing directions for wiring them together.

Please let us know if you have any questions.

You are welcome and thank you for joining our forum. Great idea to upgrade the battery pack so it has the same amount of drive time. We have not modified a Crazy Cart XL with a 1000 Watt motor yet so I am not sure how these parts will fit into the space that the cart has. So I will post dimensions of the parts before their links:

Motor Options:

• MOT-SD361000 (4-1/2"(H) x 4-1/2"(W) x 4-3/4"(L) including shaft) electricscooterparts.com/motors36volt.html
• MOT-SD361000FW (4-1/2"(H) x 4-1/2"(W) x 5-1/2"(L) including shaft) electricscooterparts.com/motors36volt.html
• MOT-361000 (4-1/4"(OD) x 7"(L) including shaft) electricscooterparts.com/motors36volt.html
• MOT-361000B (4-1/4"(OD) x 7"(L) including shaft) electricscooterparts.com/motors36volt.html

Controller Options: (SPD-361000B is smaller in size and easier to wire, SPD-362000 is more heavy-duty but requires a heavy-duty power switch or power relay)

• SPD-361000B (3-1/2" x 2-1/2" x 1-1/2") electricscooterparts.com/speedcontrollers36volt.html
• SPD-362000 (6" x 4" x 2") electricscooterparts.com/speedcontrollers36volt.html

Batteries: (22Ah batteries should provide the same ride time with a 1000 Watt motor)

• BAT-12V22A (7-1/8"(L) x 3"(W) x 6-5/8"(H)) electricscooterparts.com/scooterbatteries12v22ah.html

Charger: The original charger could be used with 22Ah batteries however it would take 10-14 hours to recharge. For the same recharge time as with the original batteries a 36 Volt 2.5 Amp or 3 Amp charger would be needed)

• CHR-36V2.5AXLR electricscooterparts.com/36vchargers.html
• CHR-36V3AXLR electricscooterparts.com/36vchargers.html

Please let us know if you have any questions.

That sounds like a good idea. Three 12V batteries will be needed to make the 36 Volt battery pack. The Crazy Cart XL's original wires should be 14 gauge which is a little thin for a 1000 Watt motor. I would upgrade to 12 gauge wire for all of the wiring between the batteries and controller.

Please let us know if you have any questions.

Hi Tim,

The only other electrical parts which would be needed that I can think of would be the battery pack, battery pack wiring harness with fuse holder and fuse, and battery charger.

The original power switch could be used with the new 48V 1000W controller if it was removed from the power lines between the battery pack and controller and went directly to the new controller's power switch connector, or if the controller does not have a power switch connector then to a power relay or contactor that switches power on and off between the battery pack and controller.
