Alt Circuit Breaker Popped Twice Yesterday

I would have expected EarthX to ship you a new battery.

Agree, was a little strange that they want to “repair” it. So long as they do it quickly, I’m OK with that.

I would demand a new battery as well. There is a problem going on with Battleborn batteries along this same line and I'm shocked to learn EarthX may have the same problem. I'll now be taking a closer look at mine annually.

Personally I would not fly the plane with that battery. Have them send you a replacement and a return label to ship this back.

Hard to find good internal photos for the EarthX batteries. The ones I have seen seem to show the terminal post is hard bolted to the BMS board but flex wired to the cells.

I would not fly with this battery.

Agree, plane will not fly until battery is repaired or swapped out. I’m going to email EarthX and request a new battery.

If your plane was built with the EarthX and you're inside of one year of your delivery date, you can and probably should go through CubCrafters for a warranty replacement. Otherwise yeah, do the best you can with EarthX.

Good job finding this!

When reinstalling the battery pay attention to EarthX's torque specs (6mm bolts: 35 in-lbs, 8mm bolts: 45 in-lbs). I'm not sure if someone over tightened a connection and if this could have been a cause for what you're seeing.

Excellent call-out. Not sure I would have looked for torque specs for battery terminals. Will update everyone.
