Overview

This is an EarthX battery accessory. The 12V LED battery accessory has a built in resistor. This makes for an easy installation and compatibility with a 10-15V electrical system. Details installation directions are located in the EarthX manual but it is very simple. To install, connect red wire to a positive bus connection. Then, connect the black wire to fault monitoring wire (also black) that is located on the EarthX battery.

Connect the positive wire (red wire) of the LED to the electrical bus (12volt positive), typically to a fuse/breaker downstream of the master switch. Connect the negative of the LED (black wire) to the fault monitor wire (wire out the side of the battery) of the battery.

Installation

  • The positive wire (red wire) of the LED should be connected to the electrical bus (12volt positive), typically to a fuse/breaker downstream of the master switch. The negative of the LED (black wire) should be connected to the fault monitor wire (wire out the side of the battery) of the battery.

    Steps:
    1: install the 12V LED light thru a hole in your control panel.
    2: cut the black wire to length desired for your installation so the LED’s black wire reaches the battery.
    3: use a wire stripper to remove ¼” of the wire insulation so you can attach the “male” spade connector to the black wire. Crimp the male spade connector to black wire.
    4: plug the male spade connector into the end of the pigtail wire from the battery.
    5: connect the red wire to an electrical bus fuse/breaker (.25-3 AMP). May have to untwist wire and cut to length. Most of the time it is most convenient to connect to a fuse on the back side of the panel. If not, it could also be connected directly to the positive terminal of the battery with a ¼” ring lug connector.

Benefits

  • With EarthX, you gain the quality and performance you want from your lithium batteries. Our experienced team commits to innovation and industry best practices to deliver batteries you can trust. We only source high-quality materials for our batteries, and we support every product with attentive customer service. The aircraft specific batteries are the ETX Hundred series, do not use the power sport batteries as they do not have all the same safety features as the aircraft specific ones.
  • As a veteran-owned, U.S.-based company, we’re proud to provide the batteries you require for your experimental aircraft.

  • Advantages Of Utilizing EarthX Batteries For Experimental Aircraft
  • EarthX lithium batteries offer many benefits for experimental aircraft, including:
  • Lightweight materials: Our lithium batteries use cutting edge technology that lead to a much lighter battery and more powerful batteries as compared to lead acid counterparts. There’s about an 80% weight savings over a comparable lead acid battery for instant weight savings.
    For Example: the PC680 weighs 15 pounds and has 170CCA. The EarthX ETX680 weighs 4 pounds and has 320CCA. Lighter weight makes installation easier and improves the handling of your aircraft.
  • Increased cranking power: EarthX Batteries do not experience the large voltage drops as lead acid batteries experience to provide you a consistent and powerful startup every time you use your aircraft.
  • Safe performance: EarthX Batteries feature a state-of-the-art Battery Management System (BMS) that monitors performance and prevents overcharging and over discharging. The BMS is key to the longevity of our batteries.
  • Long-lasting: With the help of the BMS, our lithium batteries can last up to six years, even with heavy use in your experimental aircraft.

  • Our Commitment To Powering Aviation
  • Innovation drives us, and we continue to develop our batteries for use in the aviation industry. We are the first and only company in the world to have a 12V FAA TSO approved lithium battery for aviation use, and this is only the beginning. Our engineers have more TSO approved models in the works to make a significant impact on this industry. We currently also have a 24V FAA TSO battery offering.
  • Lead acid batteries have been at the forefront of aircraft power for decades, but we want to see change. Our developments in lithium iron phosphate batteries offer greater power, performance and safety for aircraft of all types. Be prepared to see new aircraft on the market that come with EarthX Batteries straight from the manufacturer.
  • We have goals in the aviation industry to make changes for the betterment of all, and we’re offering our support wherever we can with a Veteran owned and operated company in the USA.

Reviews

This works as intended, but the design could be better. If they had put a ballast resistor of appropriate rating for a dead short down stream at the connection end of the red wire instead of at the LED, then a fuse would not be necessary.
