Interesting facts about the LiON

General

It is not witchcraft to build a charger with a universal input voltage (100-240 V). With practical use in mind, and to maximise energy efficiency while minimising product size and weight, we decided to launch models with only one specific input voltage range.

We are sorry to know that your LiON is broken. If the damage is not due to incorrect operation and is still within the warranty period, please contact our customer service at for a replacement. Otherwise, please also contact us and we will see what we can do for you … for example, a special price for the purchase of a new LiON.

It is definitely our plan to launch the charger for 24 V and 48 V batteries. The schedule depends on user feedback. Please fill out the contact form so we can hear more from you.

Unfortunately, the LiON is NOT waterproof, although the charger is robust, strong, reliable and protective. Please keep the LiON away from water as this may not only cause damage but also electric shocks.

The LiON is suitable for both 50 Hz and 60 Hz mains input frequencies.

It is definitely our plan to launch the US version. The schedule depends on user feedback. Please fill out the contact form so we can hear more from you.

Each LiON Smart Charger comes with a 2-year warranty.

Technical

Scientists have been doing intensive research on how to better protect lithium-ion batteries. A publication from the Technical University of Munich in Germany (titled: Aging of lithium-ion batteries in electric vehicles) suggests some ways to maximise battery life. “Avoid very high states of charge (i.e. battery level)” and “Apply appropriate charging currents” are two of the recommended practices. Details can be found at:

There are a few things that make the LiON a smart charger. They include:

1. adjustable/selectable charging current and percentage of battery charge according to the user’s preference,
2. ability to communicate with users via NFC and mobile app,
3. ability to record key statistics of each charge, and
4. ability to check the health of the battery and alert users when the battery is out of service.

Not all, but very many batteries can be charged at 4A. Please check the user manual of your battery for the highest charge current your battery will accept, some battery management systems limit the charge current.

The highest charge current of the original charger supplied with your vehicle is not necessarily the highest charge current your battery will accept. In general, batteries of 300Wh or 8Ah or more should have no problem being charged at 4A.

It depends on two factors to determine the charging parameters:

1. the time you have before using the vehicle.
2. the expected mileage before the next possible charge.
3. not charging the battery unnecessarily and using a lower charge current when time permits are two good ways to protect your battery and extend its life.

The loading time depends on three factors. They include:

1. battery level before charging,
2. charging current, and
3. desired battery level.
4. the LiON would make an estimate of the charging time and communicate with the LiON app after you send the command. You can also trigger a reminder alarm when the estimated time has elapsed, if necessary.

No. In many cases we have found that vehicle manufacturers do not necessarily supply a charger with the highest possible charging current. For many users, this may be the reason for using the LiON.

Compatibility

Simply download our LiON App from the App or Playstore, where you can find the suitable batteries and charging cables.

If your battery is not listed in the app, please check whether your bike or scooter has 36V batteries (max. charging voltage at 42V). Then select a plug available in the list that matches your vehicle’s connection socket.

Alternatively: contact us if you need help.

You can check this first using the app. If you cannot find your vehicle we can check this for you, please take three photos of the following items and email them to us at :

Original charger label
Vehicle battery label (or battery specification in the vehicle owner’s manual).
Original charger plug on the battery from the bike/scooter.

We would check and confirm whether the LiON works for your vehicle based on the information provided. We may also contact you for further information.

You can manually enter/select the necessary parameters in the LiON app to configure the LiON. The parameters include the battery voltage (this model of the LiON only supports 36V), the battery capacity (in Ah or Wh) and the maximum allowed charging current (please refer to the battery label or the specification in the vehicle’s user manual). The LiON will then charge according to the information given.

The highest charge current of the original charger supplied with your vehicle is not necessarily the highest charge current your battery can handle. In general, batteries of 300Wh or 8Ah or more should have no problem being charged at 4A.

Contact us if you need assistance.

We offer you a choice of different connector plugs. However, we are aware that not all vehicle models use the most common connector plugs; and if they do not, the LiON may not suit you at this time! However, we will continue to add cables with different connector plugs to welcome more vehicles to our range. And for some special connectors, you could choose the XLR-4 connector from us and then buy an adapter on the market. Contact us at if you need help.

Nothing found, then ask us directly!

In use

You could use an additional output cable from us with different connection plugs for two vehicles.

Yes, it is mandatory to create the battery profile so that the LiON can properly record the battery statistics, which is a very useful tool for monitoring the battery status. Don’t worry, creating the battery profile only takes a few steps. Just do it!

The charging statistics report displays statistics such as the accumulated charged energy, the record of the last full charge, the health status of the battery and the previous charging logs.

After each charging process, the LiON saves the charging log, which records the most important statistics of the process. This charging log is stored in the charger and automatically uploaded to the LiON app with the corresponding profile during the next NFC communication.

If the charging process was interrupted, e.g. when the mains plug was changed or a new command was given to change the charging parameters, the LiON would consider this as a new charging event after the interruption. Two separate charging logs would be created in such circumstances.

The charging process would start automatically each time it is plugged into the vehicle, according to the last setting. The LiON cannot recognise which vehicle/battery it has been plugged into due to the limitation of the batteries. Therefore, in order not to charge the vehicle/battery with wrong parameters or mix up the charging protocol of different vehicles, it is strongly recommended that users should communicate with the LiON before plugging it in to start charging.

The owner of the LiON should follow the steps below:

  • Download the LiON app from either the Apple App Store or the Google Play Store.
  • Create/configure the battery profile in the LiON APP.
  • Select the desired charging current and maximum charging percentage in the LiON app.
  • Place the mobile device on the LiON for NFC communication.
  • Connect the LiON to the vehicle.
  • The charging process begins.

It depends on two factors to determine the charging parameters:

1. the time you have before using the vehicle.
2. the expected mileage before the next possible charge.
3. not charging the battery unnecessarily full and using a lower charge current when time permits are two good ways to protect your battery and extend its life.

LiON App

Yes. Each LiON app can create profiles for up to 10 batteries. Individual charging statistics could be displayed.

The LiON app would communicate with the LiON via NFC. Therefore, it is necessary that the LiON app is installed on mobile devices with NFC communication function.

Yes. In order to display the correct charging statistics for the individual batteries, it is necessary to create a separate profile for each individual battery. But don’t worry, creating a battery profile only takes a few steps. However, you should label the batteries correctly and select the correct battery profile before you start charging so that the statistics count correctly.

Yes. Users can manually enter the parameters for configuring vehicles. The parameters include the maximum charging current of the battery, as well as the battery capacity. Some vehicle models are listed in the compatibility list where the configuration information would be filled in automatically. Manual entry of the parameters would be necessary if the vehicle model is not yet included in the compatibility list.

The charging statistics report displays statistics such as the accumulated charged energy, the last complete charging record, the battery status and the last 3 charging logs.

Users could set the charging current (1/2/3/4A) and the maximum charging percentage of the battery. Users could also set a reminder alarm after time estimation from LiON.

The LiON app can be downloaded from both the Apple App Store and the Google Play Store.
