Frequently Asked Questions

Q: Is a battery included with the U2 thruster kit?
A: No, the battery is not included and must be purchased separately. We recommend a 12-16V lithium battery. A 100AH battery provides approximately 2-3 hours of run time.

Q: Does the ESC have low voltage cutoff protection?
A: No, the ESC does not have low voltage cutoff. It does include overload and overheat protection to prevent damage during operation.

Q: Can this thruster be used directly in water?
A: Yes! The ESC features a full metal housing that is completely submersible and can be used directly in water. The products use soldered joints and are ready to use when connected to power.

Q: What watercraft is this thruster compatible with?
A: The U2 kit is compatible with ROVs, fishing kayaks, electric boats, DIY pontoons, underwater drones, and other marine applications requiring 12-16V brushless propulsion.

Q: Can it be used in saltwater?
A: Yes! The thruster is made from corrosion-resistant and anti-oxidation composite materials specifically designed for use in seawater environments.

Q: How fast can it propel a kayak or boat?
A: The U2 set can push approximately 100kg (220lbs) at speeds of 1-3 km/h, suitable for controlled navigation of small watercraft and ROVs.
