Enginer Prius PHEV Conversion Kit Reviews

Positive Reviews


All Good


Pros: relatively easy install. +++75 MPG

Cons: poor documentation. nonexistent instructions

Was a pretty easy install. Have had confusing things happen which are not documented. Also having BMS (Battery Management System) issues, which may now be cleared up. Basicly the documentation is not really great. I had to piece together information from the supplied video, the "install document" and on-line user information. (Prius chat...)   For example, no document mentions anything about the EV mode wire. (and the fact that EV mode is included in the switch - you don't need to buy a separate EV switch) I just think someone needs to take an overall look at the product and write it up properly - in English:) no offense to anyone...    My install still has some...

Pros: ease of use, easy installation

Cons: none

I installed the 4kwh system a few weeks ago.  The installation took a Saturday - about 6 hours.  I can see it taking much less time the second time.  There are a lot of revelations that occur while installing.  It pays to put the batteries in the box after it is in the car- otherwise it is very heavy.   Using it is seamless.  I easily get 70-90mpg in real world driving.  There is a learning curve to driving with it.  Each time I use it the mileage improves.  Jack is great with his customer service.  There is a bit of tinkering, but nothing complicated.    As with any new technology there will be surprises.  So...
