One note on using the EarthX battery. The EarthX battery typically used for aircraft are capable of up to 680 Amps peak draw while cranking and 320 Amps continuous. Your starter will draw 125 - 150 amps while cranking. If you reference FAA Circular AC 43.13-1B Chapter 11, figure 11-3, Conductors for Intermittent flow, you'll find the minimum acceptable wire size for this battery and starter combination would be 2 gauge. That would be 2 gauge wire from the battery to the master, the master to the starter, and ground back to the battery. Also ensure than any terminals are heavy enough and properly secured. Anything less and you are looking at starter performance issues, wiring overheating, and possibly burned wiring. Additionally, depending on the output of your charging system, you need to ensure your wire sizing is up to snuff to carry the current for charging the battery as well.

My engine does not have a magneto, I depend on two electronic ignition modules which then requires me to have a good electrical source along with my alternator...My previous batteries were lawn and garden 330 CCA type, both failed with 6 months of service. I finally bit the bullet and bought an Earth X LiFoPo battery (a little pricy but...) I installed it today and will test it out tomorrow.Does anyone have experience with the Earth X batteries or did I jump from the frying pan into the fire?Luis
