Do not leave the battery unattended while plugged into the charger. Do not store the batteries
connected to the charger.
Battery Basics & Care:
NOTE: Never charge your battery when it’s temperature or the space it is stored in is below freezing. Failure
to follow this rule could result in serious injury, death, and property damage.
The chargers do stop charging when the battery is fully charged. When charging your battery, do not charge
near any potentially flammable material. Charge in a safe fire-resistant space. If you are storing the e-bike
for more than a day, do not leave it plugged in. It is best to leave it charged to 80% but unplugged. The
button on the top of the battery works as a charge gauge. It is not an on-off button. When riding always plug
the charger port with the rubber cover. If moisture gets in, the battery can be destroyed. Everyone is
encouraged to learn a little bit more about the basics of lithium ion battery care and proper treatment. For
extended life, charge your battery to 80% and use it until it is at 20%. Depending on the charge level when
plugged in, it takes 3-6 hours for the battery to fully charge when using the standard charger supplied with
the bike. Charging for 1-2 hours will keep it near 80% depending on last usage. You can check the charge
percentage on the display. If storing for longer periods, it is a good idea to store your battery with a 40-80%
charge. Check the battery once a month. If the battery drops to 25% or lower, charge it up to 40-80%.
Recommended storage temperatures are 50°-77°F and will provide the best performance out of the battery.
Storage should be done in a dry area.
