The EarthX Lithium batteries (LiFePO4) are designed to be a light-weight, maintenance free replacement of your standard lead-acid battery.
These batteries will work with any vehicle charging system and "modern" lead-acid battery chargers, thanks to the exclusive built-in electronics (Battery Management System, BMS).
No other motorsport lithium battery manufacturer offers a battery with built-in electronics to protect it from over-discharging, over-charging, plus keep the cell's charge level balanced.

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.|
Purchased this after to go in experimental aircraft. It starts better than it ever has in 10 years of flying. Highly recommend it.
