>From what I understand, it was looking at the tech itself - the onboard circuitry. There was also a bit of grandfathering since they'd been used unofficially for a while with no incidents. I see Sean has popped up here so the GFA airworthiness group would be aware of it, probably just a case of sending an email to officially ask for approval to cad or [email protected], then waiting some time for a bit of investigation.

What were the evaluating criteria used to approve Fusion?

The internal circuitry is designed to make the battery "look" like a standard lead acid or gel cell type and the EarthX brand is used in Experimental homebuilts connected to the charging system instead of a lead acid or gel cell. That brand also can be used for engine starting. They are available in Australia. There was a good article in Kitplanes a while ago on the manufacture and testing of those. As the battery "looks" like a standard lead acid no mods to the aircraft charging circuit are necessary and any good lead acid battery charger should work. If you try to use an intelligent LiFePO4 charger you may get a conflict between the battery internal protection and the intelligent charger. See that. It would be nice to know what exactly the approval process for the Fusion brand involved. Mike .
