Just lithium. For you Earthx battery people mounting the battery(s) anywhere aft of the firewall this would be the something like the EXT-900-VNT (VNT for vent).
Nothing to stop you from using a non-vented EarthX - but watching the EarthX videos it seems they recommend it. If I ever was to use an EarthX and mounted it aft of the firewall I would only use the vented version.
For my RV-8 I mount one PC-625 battery in the the forward baggage well, the second in the normal aft location. Both are mounted using modified stock Vanís RV-8 battery trays. I did this as my W&B calculations (IO-360-M1B, Hartzell BA prop, Grove gear) worked out best this way. 370 hours on the plane and Iím very happy with the W&B.
