Yamaha Drive2 Alltrax 650A AC Controller Kit
Your Drive 2 is already an AC cart. This is a controller upgrade, not a DC-to-AC conversion. It replaces the factory AC controller and runs your existing factory AC motor, so you get the performance without paying for a motor you already have.
What changes is everything the factory controller capped: 650 amps on tap, a higher and fully programmable top speed, stronger torque and hill-climbing, and regenerative braking you can adjust. Set speed and torque presets and tune regen over Bluetooth from an iPhone, Android or laptop. Throttle calibration is automatic on first power-up, and a built-in fan keeps it cool under load.
Includes
- Alltrax AC1 650 A controller with Bluetooth
- On-the-fly programmer — speed and torque presets, regen braking control
- Mounting plate and hardware packet
- Wiring kit with OEM connectors for the factory Drive 2 harness
- Installation instructions
No motor is included, and none is needed — the controller drives your factory AC motor and supports AC motors up to 5.5 kW.

Frequently asked questions
Drive 2 or G29 Drive — which do I have?
This kit is for the Drive 2. If you have the earlier G29 Drive or a G19/G22, you need a different Alltrax controller — see our Yamaha motor controllers, or contact us with your model and year and we will confirm before you buy.
Do I need a new motor?
No. The Drive 2 left the factory with an AC motor and this controller drives it, which is why this kit costs far less than a DC-to-AC conversion.
Will I need a bigger battery pack?
At 650 A the controller can ask for more current than a tired pack will deliver. For the full benefit, pair it with one of our lithium battery packs.
Is it new or remanufactured?
Brand new only. We do not sell remanufactured controllers, motors or kits.
