Battery Safety Precautions
Standard Bearer Machines recommends keeping the following immediately accessible where you charge
your bike
•
Class D Fire Extinguisher: can be used in the event of a lithium fire
•
ABC Fire Extinguisher: If you cannot get a Class D, this will do the job by preventing other
materials around the ruptured battery from catching on fire.
If your charger typically takes 4 hours to charge your battery, but it seems to be taking longer, unplug
the battery and investigate. If you suspect a bad BMS, smell the top of the battery. If there is a burnt
smell, it is a failed BMS and stop charging immediately. If nothing is wrong, it is okay to continue
charging as the battery is simply balancing while it is charging and it may take longer than normal.
If you experience a sudden loss of power while riding your Rungu,
STOP IMMEDIATELY
. Turn off the
Electric Juggernaut and inspect your battery system. Check for a burnt smell and inspect there are no
melted or shorted wires. Shorted wires or a burnt smell indicate a shorted or failed BMS, stop using
Rungu and contact us as soon as possible.
If you notice that your battery is swollen, damaged, or smoking contact Rungu Support immediately so
we can diagnose the problem and talk you through next steps.
Catastrophic Battery Failure
Although extremely rare, all lithium batteries are capable of catastrophic failure if mishandled or
treated. The following are guidelines for a battery pack failure. Great caution needs to be exercised
during a catastrophic battery failure.
WARNING:
AS SOON AS A PROBLEM IS DETECTED (BATTERY IS HISSING, YOU SMELL A BURNING
SMELL, IT IS BILLOWING SMOKE ETC), TAKE BATTERY SYSTEM OR BIKE OUTSIDE IMMEDIATELY, AWAY
FROM ALL STRUCTURES AND PEOPLE, PREFERABLY ON CONCRETE (LIKE A DRIVEWAY).
Observe the battery pack from a safe distance. Monitor the battery pack until the cells drop below
critical temperature and start to cool off.
Contact local authorities if necessary!
