5.
Plug the battery charger into an AC wall outlet using the provided AC cord. A red light should
appear on the charger.
6.
The small yellow connector mates with the charger plug. The connector is keyed, so there is
only one way that the plug will fit.
NOTE:
You may hear a “pop” sound when you plug in the charger
that comes from a spark
that occurs inside the connectors when the two connectors mate. This occurs if you
haven
’
t plugged the charger into the AC outlet first. The spark results from the potential
difference between the battery and the charger.
WARNING: ONLY USE THIS CONNECTOR TO CHARGE.
EVEN THOUGH THESE BATTERIES
HAVE BUILT-IN BATTERY MANAGEMENT SYSTEMS, A BMS FAULT OR FAILURE MAY
OCCUR. IF YOU EVER NOTICE A BATTERY PUFFING, STOP CHARGING THE BATTERY, PLACE
IT OUTSIDE ON CONCRETE A SAFE DISTANCE AWAY AND MONITOR IT CLOSELY FROM A
SAFE DISTANCE TO MAKE SURE ALL IS O.K. GIVE US A CALL/EMAIL US IMMEDIATELY IF A
BATTERY BEGINS TO PUFF, AND CONTACT RUNGU FOR GUIDANCE ON THE NEXT STEPS.
DO NOT ATTEMPT TO USE A BATTERY AFTER IT HAS SWELLED AND EXPANDED OR
“PUFFED” SIG
NIFICANTLY.
8.
Wait until the light on the charger turns green for a full charge. You should expect a full
charge in fewer than 3 hours. If it fails to charge, please look at the troubleshooting section
for further information.
NOTE: You do not always need to wait for a full charge, you may use your batteries at any
time since the batteries have no memory. For extended use, it will always be better to get
a full charge so that you do not deplete your batteries too far when you ride. It is better in
the long run to use less than 80% capacity of the battery when riding if possible
.
CAUTION: REFER TO THE
SECTION IN THIS DOCUMENT FOR MORE
INSTRUCTIONS ON HOW TO MAXIMIZE THE LIFE OF YOUR BATTERIES.
