The Cake-1000 is the battery charger that comes with Kalk and Osa.
¶ Usage
The small lights show you if your bike is charging, fully charged or if an error has occurred.
When connecting the charger to your battery, CAKE recommend waiting 30 minutes after riding and then connecting in the following sequence:
- Make sure that the device is switched off and disconnected from the mains
- Make sure that the charger is connected to the battery
- Connect the charger to mains supply
