6.4 Battery charging
The charge status is shown on the display. To check the charge status, briefly press the button on top of
the battery. Up to four LEDs will light up for a few seconds to indicate the charge status.
•
Make sure that the switch on the side of battery control unit is set to OFF.
•
Plug the mains adapter into the mains socket outlet and switch on.
•
Gain access to the charging socket on the battery box by lifting the protective cover.
•
Connect the plug on the lead of the battery charger to the socket on the battery.
•
The Red light on the charger will show red when charging and will turn Green when fully charged.
You may charge your batteries after every use, whether fully depleted or not (lithium ion batteries do not
suffer from so-called “memory effects” if they are charged when not fully depleted; similarly, partially
charging a lithium ion battery has no detrimental effects). Allow the battery to come to room temperature
before charging (do not charge the battery when it is below 0°C/32°F or above 50°C/122°F). During
charging, an LED light on top of the charger will change from red (indicating the battery is actively being
charged) to green (indicating the battery is fully charged). The charger and/or battery may get warm to
the touch during charging. Unplug the charger from the wall following charging. A full charge when the
battery is fully depleted should take about five (5) hours.
When your batteries are not in use (for instance, during winter), make sure to fully charge them at least
once every three months. Store your batteries when not in use in a cool, dry environment. Never leave
your batteries in a hot environment, such as in a closed vehicle exposed to the sun.
Your battery capacity will decrease over time, depending on how many full cycles it has experienced (e.g.,
how many times it has been fully recharged). You should expect to get at least 500 or more full cycles
from each new battery.
Your batteries are sealed and do not require any internal maintenance. Do not attempt to open them or
modify them in any way; doing so may result in fire, injury or damage to the batteries.
Although protected by the BMS (Battery Management System) the danger of lithium battery fires has been
widely reported. An electric bike sized lithium battery pack contains sufficient stored energy and volatile
material that significant heat release and damage occurs if something goes wrong.
Always assume the worst could happen and only charge the battery when you are around, or at the very
least where any incident would be contained such as in a garage.
