ETX680C

$379.00

The ETX680C lithium battery only weighs 3.9 pounds but delivers 680 cranking amps!

This battery is intended for 400ci engine size or less; 60 amp alternator/generator or less. Can be used in experiemental aircrafts or race cars, just match up the alternator output with the correct battery.

Our ETX battery series 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, our ETX Hundred series aircraft 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 (SOLD SEPARATELY) to alert you to the state of charge and state of health of the battery. (Please see manual for details)

EarthX is proud to be the most trusted brands in the experimental aircraft market.

The difference between the ETX680 and the ETX680C is physical size. The “C” is for compact.

    EarthX Portable Lithium Iron Phosphate (LiFePo4) Jump Pack

    $129.00 $99.00

    SALE HAPPENING NOW WHILE SUPPLIES LAST!

    One of the most amazing gadgets out there! No need to ask anyone for assistance and you can jump your own vehicle in seconds!

    The EarthX Jump Pack is light and compact so you can take it anywhere to start just about anything with 400 burst cranking amps (cars, up to a V8 trucks, boats, motorcycles, ATV/UTV’s , airplane’s and snowmobile’s, riding lawnmower’s, etc.).  The entire kit only weighs 1.4 pounds and comes with the jump pack unit, the plug in the wall charger, alligator jumper cables, and the case! The EarthX Jump Pack is custom designed for rugged off road use featuring dust covers for all power and charge ports, plus an “easy hold” grip with a rubber like finish.

    And like our EarthX batteries, the EarthX Jump Pack uses lithium iron phosphate (LiFePo4) cells, not Lithium Cobalt (LiCoO2)!  This is a big deal! LiFePo4 is the most stable and robust of all the lithium chemistries, has  double the life span compared to lithium cobalt and is the correct voltage range as your vehicle you are jumping!

    The EarthX Jump Pack uses 4 Lithium Iron Phosphate (LiFePo4) cells in series at a voltage range 10V-14.6V vs. a Lithium Cobalt (LiCoO2) jump pack that uses 3 cells at a voltage range of 9V-12.6V.

    Why is this a very important difference? This means the voltage of the EarthX Jump Pack  is 100% compatible with your vehicles charging system and at no risk of over charging as the normal charge range is up to 14.6V, which is what your vehicles will produce once started. The jump pack that uses the Lithium Cobalt cells must use diodes in the jumper cables to protect the cells from the excess voltage and why they say to immediately remove the jump pack after start. If this diode fails, the Lithium Cobalt cells can and will be overcharged causing damage to the cells and even cell rupture/fire.

    Here at EarthX, performance and safety is paramount and it would be much cheaper to use the inferior cells but we want you to have only the best!  If the jump pack you are researching doesn’t tell you it’s a LiFePo4 technology, it not!

  • I can’t believe how many companies today do not answer their phones or have knowledgeable employees. EarthX knows their stuff and answers their phones!

    Will Y.

    5 star customer service!

  • I have been following this company for years now and I am constantly amazed at their ingenuity. I notice that their “competitors” try and copy them which is always a back door compliment.  Kuddos to you EarthX!

    Sam H.

    Innovative

  • I did a lot of research and found “cheaper” batteries out there but none that had the extensive manual or documentation to back up their “marketing” materials. I am very pleased with this product but also the company too as they are professional and seem to really care about their customers which is rare these […]

    Quality is never cheap

  • I finally replaced my chunk of lead years ago with an EarthX battery and the difference is incredible. My bike handles better and I never worry about it starting! I’ve had it 4 years now and couldn’t be happier.

    Tim H.

    JUST WOW!

    Tim H.

    JUST WOW!
  • Dear EarthX, I want to thank you for great service. You warranted my battery, and exchanged it for a new one. I want you to know that I thought I was in for a fight, not used to such good service. Very well appreciated.  Some times doing business online , especially second party , can be […]
    Beyond excellent customer service!

  • I have to admit that your customer service is well above the standard level that I’ve received from other aircraft businesses. I was expecting a “shrug of the shoulders” response regarding the limited two year warranty for a battery I purchased three years ago. What I was surprised to learn is that your company is […]

    Customer service well above standard!

  • When I called a real person picked up the phone when I had an issue with my battery. I then emailed your Warranty folks and everything was taken care of right away. I got a call right back, followed up by an email, with a replacement battery in the mail! That’s Customer Service! I will […]

    Great customer service!

  • Thanks a million for the “care package”.  It showed up this afternoon.  The 36C was exactly what my 1190R needed, starter spins up like it should now – I should have bought this battery 3 years ago when I first got the bike.  I appreciate your interest and help!

    Craig D

    I should have done this 3 years ago!

  • Dear EarthX,

    I have made 10 or 15 engine starts since installing the new EarthX battery last week. It is PHENOMENAL! It spins the engine over much faster and makes the engine starts much better.

    Gary W. (in an airshow performance plane)

    PHENOMENAL!

  • Thank you so much for the quick reply. You folks have the service side of this business down pat. I can’t tell you how much it means to me to have been able to sort this problem out so quickly and painlessly. In my years in business I graded my […]

    Customer for life!
  • My Aprilia Futura 1000cc V-twin doesn’t like batteries recommended by the factory and when using them it struggles to start and usually kills them within 2 years. It also likes to leave me stranded costing $400 for tow trucks and the embarrassment comes free of charge. One of my co-workers is using your batteries […]
    3 years later…..love my EarthX

  • OMG!!!  You sold me a battery for my RV-8A at the Northwest Aviation Conference in Puyallup, WA. I put it in my plane a few weeks ago but the weather did not co-operate until today. What a difference! My starter does not whine anymore and it cranks way faster! Also, I still have not lost […]

    OMG! You were right!
  • Recently purchased and installed an ETX680C for my experimental plane. The 680C replaced a Ballistics Performance EVO2 battery. Your battery is FANTASTIC. There is an amazing difference in cranking performance–I can almost taxi my aircraft when just running the starter!

    Ted W.
    FANTASTIC PRODUCT!

  • Questioned myself for buying such a costly battery, however it has been one of my best decisions. This battery has performed exceptionally well and I will continue to upgrade to these Lithium batteries on all of my sport equipment!

    Buck

  • The weight loss on my bike was felt immediately. Feels like a have a smaller bike now. Still can’t believe how light weight and strong starting ability. I’m thoroughly impressed. Hope it can hold out for the long run. Very happy so far. Install took a little TLC by bending some loop connectors but battery […]

    K1200RS

  • By changing to this battery in my airplane, I shaved 10 lbs off the forward area and gave myself a far better battery. Easy fit too.

    Don

    Great weight saver in my aircraft!

  • Twice the CCA’s at less than 1/3 the weight. Great product and great company!

    Scott

    ETX36C

  • Purchased the ETX900 for my 3300 Jabaru aircraft engine in my Zenith CH750. The new battery spins the engine significantly faster, allowing for starting the engine without preheating every time (anytime it was below 60 degrees F) What a difference it made and saved me just over 10 pounds. It’s worth the price.

    Eric

    Zenith CH750

  • After flying all weekend I must say I am impressed with this battery (ETX 900). My Odyssey PC 925 always worked well until recently with 4 years of use it started turning the prop a bit slower each time during start.

    Your ETX 900 turned my engine and prop (IO-360, C/S) faster than I’ve ever seen […]
