Double the Capacity of the River from 288Wh to 576Wh.

The RIVER Extra Battery is designed to integrate with RIVER to increase the energy capacity of the unit. You can easily double the capacity of the RIVER from 288Wh to 576Wh by attaching the RIVER Extra Battery to the main model. The RIVER Extra Battery CANNOT be used alone. You will need to install the module on RIVER to use. The battery kit contains everything you need to install the battery onto the River (longer screws, screwdriver, user guide)

Note: Please pay attention, and avoid static electricity during the installation process.

2. Please remove the 4 screws on the bottom cover. The extra battery module should be positioned as shown in the figure.

3. Align the male and female battery sockets, and connect them. Close the bottom cover. Take the four long screws from the kit and screw them on the screw mouth.

4. Put the RIVER upright and turn it on. The extra battery’s ambient light will turn on. On the RIVER’s display, if the extra battery module indicator light is on, then it is activated successfully. If the ambient light or the extra battery module indicator light is not on, repeat the installation steps, and then check the connection.
