300A 75V V75_300 based Watercooled Speed Controller + MTI85165 Waterproof Inrunner Sensorless Motor + MTSKR1905WF IP67 Waterproof Remote + 300A 85V Anti-spark Switch + Water Pump Set for Efoil, Electric Hydrofoil High Voltage Electric Vehicles, etc.,
Frequently Asked Questions:
- How much voltage can be used for this kit?
- The motor is 200KV, max voltage can use is 50V.
- Is water pump necessary?
- The controller is watercooled, not fully waterproof, so if you will use this for water sports like Efoil, surfboard, then please better order together with the water pump for cooling.
- Is anti-spark switch needed?
- Anti-spark switch function is to protect your battery and VESC systems from damaged by power surges when startup and power up, especially when use high voltage, so anti-spark switch is recommended. Our MTS2009AS anti-spark switch can also cut off positive pole power, save your battery power and more convenient to use.
- What applications can this kit be used to?
- Efoil, electric hydrofoil, electric boat, electric kayak, electric motorcycle, ev car, agv car, heavy duty cargo robots, electric water sports, counter current swimming machine, etc.,
- Set in VESCTOOL:
Motor Current Max: ≤300A (According to your motor current)
Absolute Maximum Current: 350A (According to your motor current)
Battery Current Max: ≤150A (According to your battery discharge current)
You can also use default values after "Setup Motors FOC" detection.

Advice after usage:
1. To expand the products life, please better wipe off the waters on the products and keep them for all dry after everytime use.
2. For this kit of the ESC, because the motor is sensorless, suggest to use the default value in the ESC, we have tested the kit before shipment with the default value, do not suggest to modify the values.
If you have other requirement on motor KV, ESC or other questions, please contact us agnes@maytech.cn
