Radinn jetboards: Tips & tutorials

Best practices for jetboard use and maintenance 

With their advanced propulsion systems, electric charging capabilities, and wireless pairing technologies, jetboards may seem like complex watercrafts, but they’re surprisingly simple and straightforward to use so long as riders are familiar with the operational aspects of the gear.

As the world’s leading jetboard company, Radinn makes exceptionally intuitive and user-friendly jetboards, and an easy way to learn how to use them is with this Radinn Tutorials article. Watching these videos will not only ensure your safety, optimize your performance, and prolong the lifespan of your equipment, it will also guarantee you have an amazing time out on the water.

Here’s everything you need to know about setting up, handling, riding, and caring for your Radinn gear.

Your complete jetboard package

Radinn’s complete jetboard package consists of one boardbag, one board model with an already installed jetpack, and one battery. 

For every complete jetboard, you’ll also receive a charger and an accessories case, with one wireless hand controller and hand controller charger, a pair of fins, the Radinn user guide handbook, a water bottle, and a board leash.

When purchasing the jetboard, you will have the chance to customize your jetpack performance and battery range. If you select standard settings upon purchase, you can always upgrade the battery to Extended range and the jetpack to PRO performance in the Radinn mobile app later on.

While not included in the package, we highly recommend you always wear a helmet, and a life vest or impact vest while riding the jetboard. Also be sure to have a whistle on you at all times to call attention in case of an emergency.

Charging the jetboard battery

Before charging the jetboard battery, it’s important to make sure that the battery has had time to cool off after use. 

Once you ensure it’s cooled, you can connect the battery to the charging cable. It may take some time to initiate, but eventually red and green LED lights will appear. 

A few moments later you will hear 2 to 3 clicking sounds and the LED lights will turn red, indicating that the battery is properly charging. 

When the battery is fully charged, the LED lights will revert back to red and green.

If the battery is in need of optimization, charging may not initiate (see article What is the Battery Optimizer feature?).

Inserting the battery into the jetboard

Start by removing the rubber connector protectors from both the battery and the jetboard.

Use the side handles to carry the battery to the board. To place the battery into its proper slot in the center of the jetboard, hold the battery’s front and rear ends. Be sure to keep the battery level while inserting it.

Note that the battery is designed to fit securely in place and some extra pressure from your palm may be needed. 

Once the battery is in place, turn all of the lock rings clockwise. Try to apply pressure around each lock at a time as you turn them into place. 

The battery is properly connected to the jetboard once all 3 lock rings are tightened.

Once tightened, the lock rings should not be loose in any way. If you suspect the lock rings are still loose after tightening, or if you feel as though you need tools to tighten them further, do not put the board in the water. Submit a request with our Product Support team and they will assist you

Charging the hand controller

Ensure that the inductive charging plate is active and the center of the hand controller, which is between LED lights 4 and 5, is correctly positioned in the center of the charger. 

As the controller is being charged the LED lights will flash one at a time—starting at the bottom of the controller and moving upwards towards the throttle—indicating the amount of charge accordingly. When the last LED light at the top of the controller has stopped blinking, the controller is fully charged.

Be sure to remove the controller from the inductive plate after it’s fully charged. Also note that, if the controller hasn’t been used in a while, it may take some time for the first blinking LED light to appear. 

To check the level of charge of the hand controller, make sure that the magnet key of the board leash is NOT connected to its fitting on the back board. Then press down on the controller’s throttle. The blinking LED lights indicate the controller’s level of charge.

Pairing and using your hand controller

To pair your hand controller, first attach the magnet key of the board leash into its fitting on the back of the jetboard. 

Then, press the controller throttle all the way down for up to 5 seconds until the LED lights begin to flash. When the lights stop flashing, the controller is paired with the jetboard.

The hand controller adjusts the speed and acceleration of the jetboard via an easy-to-use thumb throttle. Apply pressure to go faster, and release pressure to slow down.

When the magnet key is connected to its fitting on the back of the jetboard, the jetpack is on and the steady LED lights show the state of charge of the board battery.

In order to ride the jetboard, the magnet key—attached to your leg via the velcro board leash—must be connected into its fitting. Should you fall off the jetboard while riding, the board leash will pull the magnet key off and the board will automatically stop.

When the magnet key is disconnected from its fitting on the back of the jetboard, the jetpack is off and the blinking LED lights show the state of charge of the hand controller. 

Jetpack dry test

Before bringing the jetboard into the water, you can test the jetpack on land to make sure everything is working properly.

First, pair the hand controller by connecting the magnet key of the board leash into its fitting on the back of the jetboard. 

Then, press the controller throttle all the way down for up to 5 seconds until the LED lights begin to flash.

When the lights go from flashing to steady, the controller is paired with the jetboard. Continue to apply pressure to the throttle. When you do this, you should hear the hum of the jetpack start.

During the dry test, the jetpack will not go into full capacity since it can’t be cooled off by the water. When the jetboard is in water, the jetpack will go into full capacity.

Removing the battery

Before removing the battery after your ride, use the side handles to tilt the jetboard and remove any excess water from inside the battery compartment.

Once you’ve drained the board, release the locks fully by turning them counter-clockwise.

Note that the battery is designed to fit securely in place and it can be challenging to lift it from its compartment. Before trying to lift the battery away from the board, use the handles to wriggle the battery from side-to-side. This will remove any vacuum that may have occurred.

Then, hold the front and rear ends of the battery, and lift straight up. Be sure to keep the battery level while doing so.

Once the battery is removed, attach the rubber connector protectors back onto the jetboard and the battery.

Take a towel and dry off any excess water that might be left in the battery compartment.

Maintaining the jetboard after riding

After you’ve completed your ride and the battery has been removed, reattach the rubber connector covers back onto the jetpack and the battery.

Clean the jetboard with fresh water, paying special care to rinse the jetpack cooling system using the Radinn water bottle included in your accessories kit.

Make sure to also inspect the jet tunnel and carefully remove any seaweed or foreign objects that may have become lodged during your ride. To do so, you may need to flip the jetboard upside down on top of your board bag or a towel.

Let the board dry out or use a towel to wipe it down before storing it back in the board bag. Be sure to never store the board with the battery inserted.

We then advise that you run the Battery Optimizer feature. Doing so after each ride will allow you to utilize the full potential of your battery.

Be sure to also give your battery a top-up charge at least every other month (see article Maintaining the battery for more).

Maintaining the battery

Proper battery maintenance is crucial for the health and longevity of the hardware.

  • It is important to always charge the battery fully before storing it
  • Be sure to NEVER leave the charger connected to the battery if you are not actively charging or optimizing it
  • Be sure to NEVER store the battery inserted into the jetboard
  • You should store the battery at room temperature (15–28 °C / 59–82 °F) in a place with dry air
  • During the off-season, fully charge your battery at least every other month so that it does not self-discharge to an unrecoverable level
  • Also always be sure to fully charge the battery before taking the board out for use
  • Regularly inspect the integrity of the battery’s hull and gasket (the foam part around the connector), and make sure that the battery connector pins are free of potential corrosion


If you have the Speed Charger or the Universal Charger, we recommend you still perform Standard Charging (Low) as much as possible.

Finally, to utilize the full potential of your Radinn Battery, we advise that you run the Battery Optimizer feature after each ride.
