Ariya 12v Battery Charging Demystified - AGM Myth Buster?
A couple weeks ago I asked if anyone had tried installing a T.E.T. LFP battery I found on Amazon and since no one responded I decided to try it out myself. It’s actually cheaper than some AGM batteries found locally so I thought I’d give it a shot. So glad I did because its been an amazing eye opener for me mainly because of the intelligent battery monitoring system that’s built into the battery. I had a totally different picture of how I thought the Ariya DC-DC 12v charging system worked. As a mechanic/EE, I now completely understand why a common lead acid battery (AGM or flooded) will prematurely, FAIL in this car. I decided to do a live recording of my commute from work to show you how the Ariya handles the 12v battery. The video has my narration and is boringly informative for only the most techy elite. So far I’m extremely happy with this $209 LFP battery from Amazon.
