For a light sport however, that can be a significant savings in weight, if you can make it work out on the w&b.
Wow, that doesn't sound good.Well that's an unpleasant surprise. When my engine reaches summer operating temps (firewall mounted battery) the battery controller fails catastrophically and causes an over-voltage. I'll be calling EarthX this week to return the battery. I'm NOT happy with this failure mode.

Protecting ANY in-cowl battery from heat is the installer’s problem. Skywagons never came with firewall-mounted batteries. Compatibility of multiple STCs is the mechanic’s responsibility.Well that's an unpleasant surprise.

********. Odyssey never had an issue. So either this battery is frail and unrobust or my exact battery has a manufacturing defect.Protecting ANY in-cowl battery from heat is the installer’s problem.
A defective battery is on them. Excessive heat is not. Put a shroud over the battery and add a blast tube from the rear baffle to push cool air through. The ETX has electronic circuitry in it, an Odyssey does not. It reminds me of Emags, which require blast tubes for each mag to keep electronics cool. Or move it to the OEM battery box like the STC intends.********. Odyssey never had an issue. So either this battery is frail and unrobust or my exact battery has a manufacturing defect.
It's not 'excessive' heat if a lead-acid battery has no issues. They've built a system that is not robust enough to handle NORMAL operating temps.A defective battery is on them. Excessive heat is not. Put a shroud over the battery and add a blast tibe from the rear baffle to push cool air through.
Here are two posts from the EarthX FAQ page
Yes, in most cases. But, temperatures in some engine compartment have been reported to exceed the battery operating temperature range. ie a Glasair Sportsman prior to 2017 and some RV7 installations in southern climates. The engine compartment is still a good place, but it takes a little more effort with the battery box and or cooling air. We have a thermally insulated battery box on our website which solves most people’s temperature concerns. But you could additionally use cooling air (thru blast tube) at that location to be sure things stay cool. How do these batteries do in the heat?

The battery is TSO'd dictating that it meets a minimum standard... and clearly it does not. Additionally none of that information is in the TSO, OR STC documentation and a companies website FAQ is not a location someone should be expected to go for this info. In fact on their spec sheet it specifically states: "EarthX’s first FAA TSO certified battery. ETX900-TSO is designed and eligible for engine compartment or in cabin installations"Can the battery be mounted forward of the firewall?

How do these batteries do in the heat?
EarthX batteries are rated up to 60°C or 140°F for normal operation, and for short term operation (30 mins) is 65°C. After shut down with a hot engine compartment (no operation) it is rated for 85°C or 185°F. Higher temperatures mean shortened battery life. The batteries do come with heat monitoring that will illuminate the LED with a 2 second on/off light and you would need to mititage the heat for a longer battery life. EarthX batteries have been installed in engine compartments with no trouble, however if heat is still a concern we do offer thermal battery boxes.
I'm surprised that was permitted. Their STC webpage says they haven't yet gotten authorization to install in front of the firewall.

While their doc organization is interesting, looking in the STC ICA doc it gives "environmental" temp maximums for install location (item g below). Maybe this is being used vs fwd or aft of the firewall?Where in the STC does it say this?
Which company? I would however point out that I am not aware of a battery failure mode that causes an over voltage situation. I suspect you have others issues. Generally over voltage is caused by the voltage regulator with the alternator online.Their customer service was pretty ****ty. They were helpful and responsive up to the point where they wanted more data and I said no, I am not putting their battery back in my plane unless they agree to cover the replacement cost of all of the avionics. They tried to persuade me to get them more data on a battery that failed by telling me my alternator would prevent an overvoltage, and maybe so, but my plane and my life is not their test equipment. Then gave me the run around for about a month on preventing a refund until I got the CC company involved. I would NOT recommend buying from this company.
I'll give you three guesses as to which company it is given the thread title.Which company?

how do you restore a testicle?Bah, Decathlon/Citabria is not on the AML and not on the projected list. My left testicle for saving 25 pounds sounds like a fair trade after gaining 38 pounds during restoration.
