Why is a scooter battery a different story from an e-bike battery?
More voltage, more capacity, more weight. A scooter battery delivers a lot of power in a short time and often sits deep inside the vehicle, with its own communication between battery, controller and charger. If that communication drops out, the scooter will not run, even when the cells are fine.
For our work that means two things. The diagnosis calls for test equipment that can handle these voltages and currents. And transport needs attention: a heavy or damaged battery cannot simply be posted. We agree that with you in advance.
What can you leave to us?
- having capacity and condition measured;
- having cell balance checked;
- faults in BMS and electronics;
- defective charge ports, connectors and fuses;
- deeply discharged batteries, for example after standing unused for a winter;
- cell replacement when the cells are worn;
- a new battery when repair is no longer worthwhile;
- assessment per batch for fleets, with reporting by arrangement.
Who do we work for?
- Scooter shops and dealers. You keep the customer and do the work on the scooter, we do the battery work.
- Sharing and rental fleets. A verdict for each battery: back into the fleet, repair, cell replacement or disposal.
- Delivery services. Batteries that work hard every day wear faster. Regular testing tells you which batteries will last the coming months.
- Importers and brands. Technical aftersales behind your dealer network, starting with a pilot for one battery type.
In practice: the defect is often not in the cells
With scooter batteries we see the same thing as with e-bike batteries. A battery that will not charge or does nothing at all does not always have worn cells. With Silence and SEAT MÓ batteries the cause is often in the electronics, while the cell pack is still in balance. Then we repair the electronics and the cells stay in place.

Frequently asked questions
KWS Seuren works on lithium batteries from NIU, Super Soco, Silence, SEAT MÓ, Segway, Askoll and Vespa Elettrica, among others. Whether a specific type can be repaired becomes clear from the technical assessment.
Yes. KWS Seuren processes fleet batteries in batches, with intake by reference or serial number and a report per battery or per batch, as agreed in advance.
Contact us first. Weight, condition and transport classification determine the packaging and the transport. A damaged or swollen battery cannot be sent as an ordinary parcel.
Then we tell you after the diagnosis, before any work is done. KWS Seuren then discusses the alternatives: a new battery or controlled disposal.
Want to have scooter batteries or a whole fleet assessed?
Send us the brand, type, voltage and quantities. We start with a small batch. You can also read how a battery diagnosis works and see our approach for lease and fleet.
