Has anyone tried the EARTH X ETX680 battery in their T-18 ? Next question...will the EARTH X ETX680 fit in a PC680 battery box ? ???

I did:
viewtopic.php?f=16&t=8143
A picture is in my post, about half way down the page. I've charged it and turned on the master switch to test it and various electric mods/repairs.
I'm sorry I can't say more...

Thanks Scott : If my PC680 battery box won't work pretty sure Earth X has a bolt in replacement to replace the PC680 box . According to them it uses the existing bolt holes ? :P

The Earth batteries are pretty amazing. the weigh almost nothing but are very powerful. A friend of mine named Larry (past T-18 builder in Oklahoma) built a Lancair Legacy with a high compression IO550 Continental on it. He used two batteries to be sure he would have enough cranking power, and because he had electronic ignition. It would start just fine hot or cold on one of them. They are pretty pricey, though.

here is a cut-sheet and video: The dimensions are near the bottom of the page.
https://earthxbatteries.com/shop/etx680c
and:
https://shop.odysseybattery.com/p/pc680.
They are not the same size. Close, I built the box on 'Feisty' to accommodate either. A bit of battery box foam helps here.
EarthX 150mm L x 86mm W x 115mm H
Odyssey 181.5mm L x 76.3mm W x 167.8mm H

I've got one in my aerobatic plane. Amazing battery. Spins my IO-360 twice as fast as the odyssey it replaced. I will definitely be installing one in my T-18.
