Sourcing Guide (FAQ)

Q: Can I directly replace my DC controller with this AC controller?

A: No, you must also replace your motor with an AC motor. SPIDERWAY can provide matching AC motor kits. The controller itself supports both 36V and 48V battery systems.

Q: Can I use my original throttle pedal?

A: Yes, the controller supports multiple throttle types: 0-5k, 5k-0, 1-4k, and 0-5V, configurable via software.

Q: Will it work with other brand lithium batteries?

A: Yes, but you may need to provide the BMS communication protocol for CAN matching. For lead-acid batteries, no communication is needed; voltage detection mode works directly.

Q: Can this controller increase my golf cart’s top speed?

A: Within motor and battery limits, you can adjust the speed limit (RPM) parameter. SPIDERWAY recommends staying within the original design safety range.
