Battery Safety Precautions
Hi Power Cycles 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, for whatever reason, your bike suddenly has a loss of power and you are not getting the same
performance,
STOP IMMEDIATELY
. Turn the bike off and inspect your battery system. Check for a burnt
smell and inspect there are no melted or shorted wires. This would be indicative of a shorted or failed
BMS which you will need to contact us directly to take care of.
If you notice that your battery system has a puffed, damaged, or leaking cell, contact Rungu Support
immediately and we will walk you through the appropriate steps to take in this instance.
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 to see if it is a pertinent problem that needs to be
addressed immediately. Monitor the battery pack until the cells drop below critical temperature and
start to cool off.
Contact local authorities if necessary!
