Frequently Asked Questions

What VESC current rating do I need for my motor?
Choose by your motor’s phase-current demand and application. 200A–500A VESC controllers suit ebikes, scooters and light robotics; 1000A-class units power high-performance eskate, EUCs and small EVs; 2000A controllers target electric motorcycles and industrial drives. Always leave headroom above your battery’s fully-charged voltage.
Do you offer OEM/ODM customization for VESC controllers?
Yes. ChatRobotic is an ISO 9001 and ISO 14001 certified manufacturer providing OEM/ODM VESC controllers, custom firmware, enclosure design and PCB assembly for 200A–2000A applications. Contact our engineering team with your specs to start a custom build.
How long is the lead time and which shipping methods do you use?
In-stock VESC controllers are shipped via DHL/FedEx after payment is received. Delivery time depends on the shipping method: DHL/FedEx priority express 3–5 business days, economy express 4–6 business days, registered post 8–20 business days, worldwide. OEM/ODM and bulk orders are scheduled by customization scope. Logistics tracking is provided after shipment.
Are these VESC controllers compatible with sensored and sensorless motors?
Yes. ChatRobotic VESC controllers support both sensored (hall-sensor) and sensorless BLDC/PMSM motors and work with a wide battery range. FOC, regen braking, throttle curves and telemetry are fully configurable through VESC Tool.
