BATTERY AND CHARGING
The Dart 500W/350W uses a Lithium-Ion battery which can be
charged on or off the bike. We recommend charging the battery
off the bike indoors, in moderate temperature conditions. To
charge the battery, plug the charger into the charging portand
then connect the charger to a wall outlet (Fig. 3). The LED
indicator light will be red when charging and will turn green
when charging is complete. When finished, unplug the charger
from the battery and from the wall outlet.
Take care of the battery to ensure a long service life:
• Charge and store the battery indoors if possible. The
battery can be removed from the bicycle for this purpose.
• Avoid extreme hot and cold temperatures.
• DO NOT submerge your bike or any of the components in
water. This action will void the warranty.
To optimize the performance of the battery over time, try and use
it (discharging and charging) at least monthly. But if you won’t be
riding your Dart 500W/350W for an extended period of time, it’s
best to store the battery fully charged. EVERY 2 MONTHS: Put
battery on the charger to maintain optimum level.
After many charging and discharge cycles, runtime and range will
be reduced. Replacement batteries are available from Serfas to
extend the life of your ebike. The lifespan of the battery is about
500 charge / discharge cycles for properly maintained batteries.
When you install the battery on the Dart 500W/350W, it locks into
place automatically. To unlock for removal, use the supplied key.
DO NOT ride the bicycle if the battery rattles or moves - it
should be firmly attached.
The Dart 500W/350W battery contains a USB port for transmitting
diagnostic data only, not for charging. It will not charge or power
devices via USB.
