Well, I am getting closer to my goal of at least 60kWh of usable HV battery in my 2013 PIP.

I think this might be a first actually… these cells will replace the cells in my 2013 Prius Plug-in and fit in the same space as the factory cells just offering me more EV mile range in the end. The 2020 Prius Prime model comes with a 8.8kWh battery and the EV range doubles to ~30 miles compared to the ~15 miles I would get in my 2013 PIP. The 2023 Prime has a 13.6kWh battery and is good for ~44 miles of EV range. For me, I need more capacity to power the massive rear electric motor I am adding!

With the addition of an AWD conversion that will use an electric motor with over 250hp, I still need more battery capacity to provide me with enough “juice” to hopefully disappoint a Tesla Model 3 RWD in a race from a street light.

From here, I have it on good authority I can use the higher capacity Tesla cells in my PHEV Prius, else if they don’t work I will be acquiring a Toyota bz4x battery and using as many cells as I can that will fit in my factory battery cell holder. I read those batteries are ~70kWh and would be all I need and then some to reach the battery capacity I am after. For New Lithium HV Batteries for your Prius, check out ProjectLithium

For those of you that want to say, “Yeah, but how long will it take you to charge?” my response is “In less than 60 minutes using a fast charger conversion kit I have in the works!

These are new cells and not from a Prius Prime. For New Lithium HV Batteries for your Prius, check out ProjectLithium
