What puzzled me that 2 batterys have same movement inside sounds like 1/4 inch. Just wanted to know if others have similar moving/shifting
I was contacted by manufacturer and it sounds like bad bach of batterys
I will post an update later after talking to them

EarthX now approved by Kaolin Aviation, the USA distributor of the UL Power Engines
Koalin Aviation is the North American Service Center for UL Power engines and a full service aviation maintenance company which offers builder assistance services located in Sandersville, Georgia. Koalin Aviation is also the designer and developer for Fire Wall Forward (FWF) Kits for installing UL Power engines into various kit airplanes.
UL Power light aircraft engines are truly modern engines featuring FADEC (full authority digital engine control) with multi-point electronic fuel injection, and dual electronic ignition (with variable timing), excellent power-to-weight ratio, and high fuel efficiency in a conventional configuration: Air-cooled, direct drive, horizontally opposed four-cylinder. UL Power Engines have been developed specifically for use in light aircraft and are manufactured to the highest standards which is why they recommend the EarthX brand of lithium batteries in conjunction with their engines for a light but powerful experience.

Hope everyone who went to Sun N Fun had a great time! Sorry we could not be there this year but we are in Hangar C at Oshkosh and we will be in Anchorage at the end of this month for the Great Alaska Aviation Gathering.
Couple of announcements, we have added Continental Motors to the list of aircraft engine manufacturers who is endorsing the EarthX aircraft batteries for use with their experimental engine line!
We are also proud to announce that Mosquito Helicopter (parent company is named Innovator Technologies) as an OEM using the EarthX line of batteries to power their amazing helicopters! In fact, they sent out a bulletin to all of their current customers recommending switching out their current battery for the EarthX battery based on their engineering data of improvements to the power and weight of their helicopters when using the EarthX battery.
More exciting announcements coming!!!
Fly Lightly,
Kathy

Battery Advice
Hi Vans forum readers! I thought I would post a simple, tried and true, piece of battery advice whether it is for a lead acid or lithium battery as many of you are getting your aircrafts out of storage and ready to fly!
A very simple suggestion for you to get the most longevity out of your battery is to: 1. Measure the voltage of the battery with a voltmeter. If it is a lead acid battery, the voltage should be 12.6V-12.8V at a minimum before you attempt to start your aircraft. If it is a lithium battery, the voltage should be no less than 13.28V. 2. If the voltage is less than the above measurements, charge the battery prior to starting your aircraft. This will make your plane and your battery happy!
Fly Lightly,
Kathy

New gadget at EarthX!
Hi Vans forum readers! Just wanted to let you all know that we really do listen to you when you send us emails or stop by and chat with us at a tradeshow!
Based on that, many of you requested/suggested a LONGER quick connect cables for either charging or jumping your battery if needed that could be long enough to actually put through the control panel (many different ways you can do that) so you can do this right from the cockpit and we have it! This cable is 48" long at the cost is $29.99.

Presenter at the Oshkosh Air show
We just found out that we are chosen to be presenters at a forum at EAA Air Venture in Oshkosh. (  ) We are very excited about this and as you all have been an excellent source of "inside" information on what pilots really want, I wanted to ask for your thoughts on the subject.
We do NOT want the presentation to be a sells pitch for EarthX! We do want it to be an informative session about questions you really want to know about lithium batteries. So that being said, what questions would you like to see addressed?
Fly Lightly,
Kathy

Potential failure modes of common BMS's built in to some of the popular LiFePo batteries, effects on the battery when the BMS failure results in the battery remaining online during overvoltage or some other event, and how to mitigate/eliminate those BMS failure modes.
The thing keeping many from embracing Lithium chemistry batteries in our aircraft is the (lack of) understanding of the above.
edit: Also a few demonstrations would be great. Hook your 12V battery to a 24V charger and show us that the BMS takes the battery offline and nothing happens. Granted, that's more of an advertisement, but something that's been asked here before.

Thanks and great question and demo idea. Quick question, you say "Potential failure modes of common BMS's built in to some of the popular LiFePo batteries".....I do not know of any other LifePo battery in this market that has a BMS at all, let alone potential failure modes the BMS could have, can you enlighten me on the brand so we can research this?

First thing I'd like to see is a presentation that shows the different types of Lithium batteries, and which ones have shown tendencies toward thermal runaways, and which ones can't. Too many people say "Lithium batteries are dangerous!!" Without knowing that there are different types.
Talk about the chemistries, and why some are safer than others.

Thanks Paul. For starter type batteries, Lithium Iron Phosphate is always used (LiFePo4) as the voltage of these cells are compatible with the charging system of the vehicle it is being used to start which is 13.3V-14.6V. They are also the most robust and stable of all the chemistries.
A common lithium battery is the type that uses lithium cobalt cells. They are very common in jump packs (not EarthX's but others), cell phones, hoover boards etc. and their voltage is 11.1V-11.8V and not used in this starter battery type of application because they are not compatible with the charging system of a vehicle. Many people lump them all in the same "boat"...."plane"....and we will make sure to touch on the differences.
