Second life for PHEV Prius that needs batteries replaced ?

Not enough information about the car

 

Most dealers won’t deal with modifications.
Buy a new battery and replace all the aftermarket stuff.
I seem to recall some Australian conversions, or maybe New Zealand

 

[e, yet the battery is now clearly due for replacement.
I am considering either to sell it as-is - typically for the hobbyist to update -, or to have a dealer convert it back to original with original battery, or to acquire the cells and instructions to update myself.
I am based in Australia, probably this is the very only converted PHEV in the country.

Any advice ?[/QUOTE]

Have you considered replacing with the Nexcell Lithium upgrade on the Project Lithium website.
(I am not allowed to post the link as I am new to this forum and haven’t enough content history).

I am in a similar situation with a 2012 phv here in Australia (Sydney) and considering both what to do with the car and old battery. The Nexcell looks like a viable alternative - around $8000 AUD for a larger battery.

However, I would also like to get some value out of the old battery as a powerwall etc for home load appliances.

Have you done any research into how to repurpose the old battery?
