About the Ultima 3.0
Best For
- Inflatable tenders, dinghies and lightweight RIBs
- Owners who need a removable battery and compact storage
- Slow-speed lake, harbour and auxiliary sailboat use
Performance in Context
The motor is designed for displacement-speed operation, not planing. Haswing publishes thrust, power and a recommended maximum boat length, but does not provide a universal speed or range because both depend heavily on hull shape, load, wind and throttle setting. Full power draws about 35 amps at 29.6 volts, so sustained maximum output uses the small battery quickly. The lower 480-watt mode reduces thrust and is the more useful setting when endurance matters.
Battery and Charging
Regional packages list a 29.6-volt lithium-polymer battery, commonly 20.3 Ah or 30 Ah depending on version. The 30 Ah pack stores about 0.89 kWh. Haswing lists a 33.6-volt, 4-amp charger; recharge time varies with battery capacity and state of charge. Because package contents differ by market, confirm battery size, plug type and replacement-battery availability with the seller.
Availability and Pricing
The Ultima 3.0 remains available through Haswing distributors, but price and included battery vary by country. The prior US-dollar figure has been removed because it could not be matched to a current official North American package. Compare dealer quotes on a like-for-like basis, including shaft length, battery capacity, charger plug, warranty and shipping.
