Fault Conditions

This table shows the most common fault conditions and possible causes.

LED Light Voltage Possible Cause Recommended Action
Slow Flashing (5s on / 5s off) Less than 12.8V Battery over-discharged (due to faulty charging system) Charge battery. Once charged, the light will stop flashing.
Slow Flashing (5s on / 5s off) Less than 13.2V Weak or failing cell Charge battery. If voltage drops below 13.2V within a few days, discontinue use.
Slow Flashing (5s on / 5s off) (>1 hour time period) 13.2V - 14.6V Weak or failing cell Discontinue use. If in flight, this is not an immediate issue unless it is in conjunction with a charging system failure.
Slow Flashing (5s on / 5s off) Greater than 15.2V Over-charging (due to faulty charging system) If in flight, shutoff charging system immediately. Aircraft over-voltage protection is required if alternator charging system is greater than 20 amps (i.e. over voltage crowbar circuit)
Slow Flashing (5s on / 5s off) 13.2V - 14.6V Cell to cell charge levels are not balanced May come on briefly during periods of high current charging until the cells are automatically balanced. Try charging with a plugin charger, like an Optimate Lithium charger.
Solid Light Any voltage BMS electronic issue Discontinue use. If in flight, this is not an immediate issue unless it is in conjunction with a charging system failure.
Solid Light that turns off after 3 minutes Any voltage Short Circuit protection was activated Nothing neds to be done.
Short Flashing (2s on / 2s off) Any voltage High battery temperature (> 65°C / 150°F) Let battery cool down prior to cranking or charging.
