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.

Why Choose EarthX
- You will instantly remove 11+ pounds compared to the lead acid battery in your experimental aircraft! Now that is a huge weight saving.
- 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!
In The Box
- 1 x ETX680
- 2 x 6mm screws
- Foam for proper fitment

Reviews
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.

Installed a EarthX battery in my Challenger 2 ultralight. What a difference, weight and performance.
Were I was placing the batt. In the plane I got to thinking about safety

Installed in my RV6A.. Works great!! Talk about some cranking power, well worth the money.
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, it’s worth every penny

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.
The Earth X Lithium Batteries are not TSO'd and are not designed for certified aircraft.
Per the supplier: These batteries do not have any limitations. You are able to mount these in any direction you would like including upside down.
Per vendor, these batteries can be charged with any charger other than a desulfating charger.
Per Earth X: We recommend either the ETX680 or the ETX900 for the Rotax 912 without external alternator. The ETX 900 is the upgraded version of the 680 but both would work.
Yes, you can connect up to two batteries in series, however they would only be 24 volts, not 28 volts, as each battery is 12 volts.
We believe the "C" stands for Compact. The ETX680C is a smaller battery than the ETX680, but has the same voltage and cranking amps. The case dimensions are listed on the web page.
Per Earth X: Yes, you can connect two Earth X batteries in parallel.
No. The voltages are not the same and you will over charge the lead acid battery and drain the lithium.
ETX680 for normal climate or the ETX900 if they are in a colder climate or just want extra cold cranking amps.
Yes, we can export this item.
