Your battery needs to charge at room temperature or a bit cooler (
10°C
–
25°C (50°F
–
77°F)
).
It generates heat while charging, but it’s designed to air
-cool; keep it uncovered and facing
upward on a flat, stable, hard surface.
NOTICE
Charging your battery in excessively hot or cold conditions or interfering with its ability to
air-cool can damage your battery or charger. Always charge your battery in temperatures
between
10° C
–
25° C (50° F
–
77° F
), keep the battery and charger uncovered, make sure
the charger is on a hard, flat, stable surface, and use the charger right-side-up.
BALANCING THE BATTERY
After each of your first three rides, follow the special charging procedure outlined below,
which will ensure the cells that power the battery are balanced. After the third balance
charge and your fourth ride, begin routine charging procedures as described in
“Routine
charging procedure”
below.
NOTICE
Your battery should arrive with between
50%
and
75%
of a charge, so it is ready for a first
ride.
1. Begin this and every charging procedure by following the advice in “Before you charge” on
the previous page.
2. Charge your battery for as close as possible to
12 hours
(but not longer), regardless of how
far you travelled. This might require leaving the charger attached to the battery and outlet
even after one of the charger’s red lights turns green (during routine charging, this green
light will be your indicator that charging is complete
—
see
“Routine charging procedure”
below for more information).
3. Disconnect the charger first from the outlet, and then from the battery. Store the bike
until you’re ready to ride.
4. Ride the bike again as normal, discharging part (or all) of the battery capacity. Repeat
battery balancing steps only after a period of long-term battery storage (see
“Long
-term
battery storage”
on page 18), if experiencing noticeable range decline, if instructed to do so
by Bowhead Customer Support, or up to once per month with frequent use as explained in
“Recommended service intervals”
on page 27. Do not perform battery balancing more than
once per month. For routine charging, follow the steps in
“Routine charging procedure”
below.
ROUTINE CHARGING PROCEDURE
When you first get your bike, follow the special charging instructions in
“Balancing the
battery”
above. For routine charging, mind the advice in
“Before you charge”
on the previous
page and then follow these steps.
1. Ensure your bike is turned off.
