Frequently Asked Questions


Question 1: Is there a light on the joystick? If so, which LEDs are on?

 Answer 1-1: Make sure your joystick wire connected with battery wires while charging. If your battery lights on a joystick shows fully charged, there is no problem with your battery. If your battery does not show as full after charging for 8 hours or more, it means your battery life has been shortened.

Answer 1-2: If there is no light on your joystick, please check the joystick and battery connections. If there is still no light, it indicates that your battery is dead. (You need to check this situation when the charger is not plugged in.)

 Question 2: If no LED is on, what color is the light on your charger when you plug your device in to charge?

 Answer 2-1: If the light on your charger is blue or red when you plug your device in, your charger is working correctly. However, if the light is a steady green or there is no light at all, it means your charger is not working.

 Cable & Assembly

 Question 1: Having trouble connecting the joystick cables?

 Answer 1: If you are experiencing difficulty connecting the joystick cables, follow these steps:

 The cable coming from the joystick is equipped with a red socket, and this socket serves as the power cable for the joystick. Connect the red socket from the joystick to the battery. The black wires coming from the joystick are for the motor connections. These cables have symbols on them; the letter "R" symbol is for the right engine, and the letter "L" symbol is for the left engine. Ensure that you connect them to the correct motors according to these symbols. If there is a thin and small cable among the cables coming out of the joystick, this cable is for accessory connections. You do not need to connect it anywhere during the initial installation.

 Question 2: Can't find your product's charging socket or connect the charger?

 Answer 2: If you are unable to locate your product's charging socket or connect the charger, please note that only you can charged from the joystick. Ensure that both the product's battery and joystick cables are properly connected when charging.

You can charge your product using the yellow-labeled socket located at the back of your battery. Simply plug in your battery to charge your product at your desired location


 Question 1: Is your product experiencing issues with folding and unfolding?

 Answer 1: In this case, please inspect the frames of your product to check if anything is bent or broken. If you identify an issue with your frame, kindly contact our technical service with pictures and videos explaining the problem in your product.

 Question 2: Is the backrest of your product not locking properly?

 Answer 2: If you are facing this issue with your product, you can slightly loosen the screws of the small locking mechanisms that secure the frames at the back of your product. This should help ensure that the locks function correctly. Make sure you do not remove all the screws; otherwise, your lock will come loose, and you will not be able to reattach it.


 Question 1: Is the joystick not recognizing your commands?

 Answer 1: If the commands are not working in the correct directions, for instance, if it moves backward when you intend to go forward but has no issues turning left and right, please check the motor connections. If they are reversed, swap them with each other. If the problem persists, it may be necessary to replace the joystick. Please contact our technical service for assistance.

 Question 2: Can the reversing sound be turned off?

Answer 2: Yes, it can be turned off. To do this, first, turn on your joystick, then press and hold the horn button and the speed decrease button simultaneously for 5-7 seconds, or press and hold the horn and speed increase button for 5-7 seconds.

 Question 3: Is your joystick reacting too slowly?

Answer 3: If your joystick does not respond when turning left and right or if it responds very slowly, for example, with a delay of 10 seconds, your joystick is malfunctioning and needs to be replaced.

If your joystick continues to respond slowly even in electric mode, you may need to restart and reset your joystick if the issue persists.



 Question 1: Is your footrest not locking properly, or are you experiencing difficulty locking it?

 Answer 1: In this case, check whether your frame is damaged or not. If your frame is in normal condition and you are still experiencing this problem, please contact our technical service with videos and photos explaining your issue.

 Question 2: Is the footrest locking mechanism broken?

 Answer 2: If the footrest's locking mechanism is broken, the locking mechanism needs to be replaced. You can purchase this part from the spare parts section

 What kind of batteries are in the Culver?

There are two leak-free Lithium-Ion batteries in Culver. These are 240Wh (24 volts / 10 amp)

How often can I charge Culver?

You can charge as often as you like. The battery cannot be overcharged, and the charger goes into power-saving mode when the battery is fully charged.

How often should I charge it?

Charge as soon as the battery charge level has dropped to one-third (three lights are on). If you want to charge more often it’s fine, the battery does not take damage from it.

How long does it take to charge the battery?

Charging an empty battery takes about 3 hours.

Can I charge the batteries when it’s cold?

Yes, you can charge the battery down to minus 10 degrees Co. If you charge at a colder temperature than -10, it is still possible to charge but the batteries will not be fully charged.

Is the range affected if it is cold outside?(MODEL COBRA-NINJA)

Yes, if you use your CULVER in minus degrees the range can be affected. At minus 10 degrees the mileage can be reduced by up to 50%.

What safeguards are there if you need to leave this outside a store?

The wheelchair is a portable model, to be able to leave it safely outside standard bicycle locks/chains can be purchased separately and used.

Questions about Charging?

Start by turning off your wheelchair (all lamps at the joystick should be off). Use only Culver original chargers.

Plug the charger into the socket on the front of the joystick. Be sure that the position of the contacts matches. Then plug the charger power cord into a socket.

Charging is indicated by a lamp on the charger. A red lamp means charging is in progress. After about three hours, the batteries are charged to 90 percent. The chair can now be used again.

After about 5-8 hours the lamp on the charger turns green and the batteries are fully charged. During charging, the charger itself becomes warm, and this is perfectly normal.

For maximum battery life, charging should take about five hours when the stack of the battery indicator at the joystick goes down to one-third (when three of the lights are green). The batteries do not damage the maintenance charge, but for maximum life, we recommend that you disconnect the charger when the batteries are fully charged.

You can charge the battery down to minus 10 degrees. If you charge at a colder number than -10, it is still possible to charge but the batteries will not be fully charged.

When it’s full charge all lights on the gauge red, yellow and green will be on. When the charge goes lower, the green light will disappear and when it goes lower, the yellow light will disappear and only the red light will remain and that’s when you would recharge it.
