Note: Not FAA Approved. Intended for use in experimental aircraft only.
The ETX680C lithium battery only weighs 3.9 pounds but delivers 680 cranking amps!
This battery is intended for 400ci engine size or less; 60 amp alternator/generator or less.
The ETX battery series is fully protected by an integrated battery management system (BMS) that protects the cell’s from over discharge, overcharge, short circuit, temperature, plus cell balancing to ensure charge levels are equal. Additionally, the ETX Hundred series aircraft batteries have redundant electronic circuits and battery fault indication. The fault indicator can be connected into your EFIS or wired to a 12volt LED light on your control panel to alert you to the state of charge and state of health of the battery. (Please see manual for details)
Note: The difference between the ETX680 and the ETX680C is the physical size. The “C” is for the compact.

The battery fits perfectly and came quickly--havent had a chance yet to actually power something up with it, but that will come.
Been in plane a few weeks. Power is awesome and it weighs a lot less than the dry cell. Money well spent.
Great battery. Light weight and reliable, itâ€™s worth every penny
Arrived as promised, very happy with the batteries performance.
Only a few days in service but the cold cranking amps really are there. Replaced an Odyssey 680 battery and was able to squeeze into padded holder. Engine turns over significantly better- had become concerned about starting before. We will see about durability but for now, worth it.
Great battery at a quarter of the weight.
Amazed how light it is.
Yes, we can export this item.
These are top post.
At this time, EarthX only makes the ETX-900 in TSO version. See Part# 11-18242.
