Battery Meter
The battery meter on the digital display is set to measure capacity of a Lead-acid battery by default. To enable accurate
measurement of Lithium battery capacity, please follow the procedure below:
1. Hold down the ‘Scroll’ button while plugging in the battery and release the button once the screen illuminates
2. If you have already set a pin code, you will need to enter this now in the top left hand side of the screen (where the time is
usually displayed). If no pin code has been set then proceed to step 3
3. Press the ‘Scroll’ button to toggle between ‘S’ (Lead-acid battery) and ‘L’ (Lithium battery)
4. Unplug the battery and leave for five seconds before reconnecting ready for use
NB : Please note that during this process the pin code may also be set. If you do not wish to set a pin code please only use
the Scroll button (‘Set’ button is used to set the pin code).
The trolley is designed to protect your battery from being fully discharged. If the battery capacity drops too low, the trolley will
cut power to the motor and the battery meter will start flashing.
