I posted this as a reply within another thread but, considering how many owners are thinking about switching to lithium, thought it worthy of its own in general discussion. The EXT900-VNT is something of a game-changer that stands alone even among the other EarthX batteries designed for experimental aircraft, but several EarthX vendors do not even list it as available.
A little more expensive and a bit heavier than the unvented version, but unique among all lifepo batteries available now in that it features a containment vessel and a pair of vents intended to overboard noxious gasses that would be generated in a thermal runaway scenario. It is really the only lithium battery out there designed to be safely mounted inside the passenger cabin, a far more battery-friendly environment than any firewall-forward location. I hope that other battery manufacturers will come forward with less expensive batteries sporting these features, but as far as I know this is the only one for now.

I have a pair of these around which I’m designing a fully redundant twin battery system with enough ampacity to allow not only dual lightspeeds, but a fully redundant twin-electric fuel pump system that will allow me to completely eliminate the engine driven fuel pump from my Airflow Performance FI system. The two together weigh about 5# less than the single PC680 they will replace.
