Give your U1 more time on the water
Build an external-battery propulsion setup around your compatible Asiwo U1 or U1 Lite with this 1008Wh outboard battery. Keep the battery separate from the motor and choose the speed setting that suits your next fishing session or exploration trip.
- 1008Wh capacity for extended surface-water propulsion.
- Compatible with the dedicated Asiwo U1 and U1 Lite system.
- A U1 Lite adapter is included.

How long can it run?
| Setting | Indicative speed | Runtime up to |
|---|---|---|
| High | 12 km/h | 1 hour |
| Medium | 6 km/h | 2 hours |
| Low | 1.5 km/h | 7 hours |
Single-motor setup. Actual speed and runtime depend on hull design, load, conditions and use. Maximum runtime is at the low setting, not maximum speed.
Running two motors increases energy use. Approximately half the runtime when both connected motors are operating.
Charging
Approximately 6-7 hours with a 42V 5A charger. Follow the battery's supplied charging instructions.
What's included and what else do I need?
External outboard battery and one U1 Lite adapter. The U1 motor, rudder or transom mount and watercraft are not included. An additional adapter is sold separately.
Not sure which setup fits your watercraft? Contact Wavez with your kayak or board model and photos of the mounting area before ordering.

This is a dedicated external battery for surface-water propulsion. See photos. It is not the compact integrated U1 dive-scooter battery. Confirm the motor, connection assembly, mounting hardware and charger for your setup before purchase.
