Kugoo G-Booster External Electric Scooter Battery

The secondary battery is connected to the platform (internal) battery of the scooter in parallel. This means that the voltages of the two packs equalize all the time. Therefore, the secondary battery charges simultaneously with the platform battery. The charger LED will light up green when both batteries are fully charged.

Software modification is only required on Xiaomi and Ninebot branded scooters. An Android device (phone or tablet) will be required for this process. At this time, there is no corresponding app for iOS. On any other vehicle, this is not required.

There are countless electric vehicles on the market, which doesn't mean we won't be able to power your vehicle! Please use the Bespoke Batteries form and provide us with all the necessary information - we will do our best to complete the project for you. Each vehicle has different connectors on its internal battery. Without providing us with this information we will not be able to help you.

By default, the auxiliary battery does not increase the power and maximum speed of the scooter per se, but it does affect power and speed indirectly. The point is that the scooter only reaches full power when the battery is full. By fitting an auxiliary battery, we will be able to ride at top speed for longer and accelerate dynamically. It is also possible to generate modified software for Xiaomi or Ninebot scooters according to your own preferences, in which we will increase the power or maximum speed of the scooter. Please note that this may lead to the motor of the scooter overheating more frequently, which may result in permanent damage to the vehicle. You do this at your own risk!

Unfortunately, it is impossible to make this clear. In theory, any tampering with the interior of the scooter or opening it up could invalidate the warranty. However, in our experience, performing installation work in a sensitive manner will not invalidate the warranty. Ultimately, it is still up to the manufacturer and their service department.

This is possible. For a price of £50 we will include a special adapter (XT-60 -> RCA 5.5 x 2.1) in your delivery, with which it will be possible to connect the secondary battery directly to the charger. You will need a charger with identical parameters (max. 4A) with the "DC5521" plug.

Unfortunately, this is not an option.

For additional batteries, this is usually a maximum of 6 working days. In extreme cases, the delivery time can be up to 10 working days. For all other orders, the delivery time is determined individually, but should not be more than 14 working days.

We know that waiting for your order can be difficult at times, so we want to give you a detailed overview of the stages we have to go through to get you a top quality product: #1 We manufacture the battery especially for you (3-4 business days): Our team uses its high level of skill and experience to create a battery perfectly tailored to your needs. #2 We thoroughly test your battery for quality (1-2 business days): We thoroughly test each battery to ensure it meets the highest quality standards and works flawlessly.
