EarthX ETX680 / 680C Lithium Aircraft Battery

Select Model:
ETX680ETX680C

Overview

Note: Not FAA Approved. Intended for use in experimental aircraft only.

This battery is fully protected by an integrated battery management system (BMS) that protects the cell’s from over discharge, over charge, short circuit, temperature, plus cell balancing to ensure charge levels are equal. Additionally, the ETX-Hundred Series 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)

If you are looking for a more compact sized battery, the ETX680C has the same spec’s but in a more compact size. Visit here to see the details of the ETX680C: ETX680C | Lithium Battery for Experimental Aircraft | EarthX (earthxbatteries.com)

  • Significant increase in cranking power. If you have been using the PC680, you will increase your CCA’s from 170 to 320 and the PCA’s from 520 to 680! Now that’s the power to crank your engine!
  • Now you can easily have a backup battery and not worry about the additional weight. In fact, if you switch from a lead acid battery and add a backup battery, so you have a primary and a backup, you still have decreased your overall weight by 50%! Note that only the ETX680C/680/900/1200 have the aircraft specific BMS.
  • Innovative and sophisticated BMS designed and engineered with redundancy for safety, reliability, and performance. These are EXCLUSIVE features!

I use the battery as a portable, no onboard charging. It seems to need charging after a single start cycle. . First couple of charge cycles the battery seemed to topout and/or settle at low voltage. Presently it settles to around 13.55v. I find it cranks far faster than an LA Gill.
