What has Earthx batteries got to do with this? Read your quoted ATSB report. That battery was a Deltran LiFePo unit.
The Earthx hundred series is specifically designed for aviation use(not TSO’D but accepted by Rotax) with dual battery management systems and a fault indication alarm. It has overcharging protection built in although a crowbar circuit is recommended as well. Unless you are an idiot, wire your aircraft so that charging can be shut down.
As far as I can tell, the Deltran unit involved in the first Jab incident has none of this. Furthermore a straight swap of lead acid for lithium without analysis of the electrical system is not a good idea.
