In my endeavor to build the Ultimate Overland Prius, one key peice to this is more battery power. Sounds odd coming from a Toyota Prius owner doesn’t it?
06/03/2021 UPDATE: 135A breakers have replaced the 120A Breakers. I finally found them!!
The toughest part was finding a small enough battery to fit somewhere in the Prius that has a high Ah [Amp Hour] ratings of the battery packs.
Runtime, potential power, voltage delivery, etc are all tied back to or are related to this significant and often overlooked rating. The science behind the Ah is simple; a battery rated at 1Ah should be able to continuously supply a current of 1 amp to a load for exactly 1 hour, or 2 amps for 1/2 hour, or 1/3 amp for 3 hours, etc., before becoming completely discharged.
The first step was to make sure the battery fit, since most 100Ah AGM batteries are too large to fit in this corner of the car, I found a 12V 85Ah Marine AGM SLA Deep Cycle Battery that worked perfectly!
Since I was removing everything for this install I figured I might as well add some sound deadening to the area. After laying the Kilmat 80 mil 36 sqft Car Sound Deadening Mat, one sheet of Noico RED 150 mil 36 sqft Сar Sound Insulation to the area then proceeded to install the battery tie-down.
