So… I often share with people that I consistently radiate positive energy. Those who meet me in person naturally gravitate towards the brightness that emanates from within me. It’s interesting how, despite the occasional odd or peculiar occurrences, today, the individual saved in my phone as Prius Yoda reached out to me.
Keep in mind, I’ve been on reddit discussing the use of a tractor or aka lawn mower battery as the main 12V in a Prius for the last few days… here is the link
In his message, he shared a photo of a reasonably priced 2000W inverter connected to a 12V battery in the spare tire well of a Prius. Accompanying that was an image of the main 12V battery, with a note about the car not starting and a hope that I might have a solution. The “1R” on the Duracell caught my attention, followed by the 500CCA. As I noted the price just above $200, it dawned on me that it was a starter battery, not a tractor battery for less than $40. The realization hit me like a revelation.
Reflecting on my experiences, I’ve lost track of the times I’ve tried to convey to people that there are aspects of the Prius that remain mysterious to us. Despite sounding peculiar, normal logic doesn’t always apply to a Prius. I can attest to this, having gone through three different battery isolators, none of which worked flawlessly due to peculiar quirks. If I were to mention that it seemed like the Prius was influencing my smart isolator, some might dismiss it outright. It wasn’t until I employed a battery combiner that everything finally functioned as expected. Interestingly, I’ve used isolators many times in other non-hybrid vehicles without encountering such issues.
I upgraded to a Victron Cyrix-CT 12/24V-120A to use alongside my battery monitor smart shunt. Another example is when I added cross-drilled and slotted rotors to my Plugin and drove down a steep road I’ve known since getting my license. Before the brake upgrade, I had a specific amount of EV miles generated between point A and B on this road, having tested it multiple times. Post-upgrade, I observed a notable increase, but skeptics who don’t own a Plugin would cite diagrams and Ohm’s law, insisting it couldn’t happen in a Prius. Yet, it did!
All this to emphasize that using a starter battery as the main 12V in a Prius is not advisable. The Prius is sensitive, and while some may have been fortunate, there’s something crucial about the Amp Hour. I haven’t figured out why yet, but I can confidently say that if it lacks an Amp Hour, it’s best not to use it. However, considering your experience with non-PHEV and primarily Gen 3 Prius models, and assuming you don’t have an added-on inverter or a second 12V battery, what are your thoughts?
Also… DO NOT MAKE THE SAME MISTAKE AS THE PICTURES YOU SEE HERE… THE CABLES FROM THE BATTERY TO THE INVERTER AND ALL THAT ARE TOO THIN!!! USING A 1700w AIR FRYER, I KNOW FROM EXPERIENCE, THE WIRES WILL MELT! A FIRE CAN HAPPEN ESPECIALLY IF YOU ARE SOMEONE WHO SETS SAY… CLOTHES OR LUGGAGE ON TOP OF THE INVERTER AND SECOND BATTERY!!! PRIUS 12V POWER INVERTER WIRING KIT WILL BE POSTED HERE IN THE NEXT WEEK, NOT ONLY HAVE I BEEN USING THESE IN MY OWN SYSTEM BUT TESTING THESE PREMADE TO LENGHT CABLES FOR THE PRIUS AND THERE IS AN OPTION TO HAVE THE WIRES FOR THE 2ND BATTERY ADD ON!
