I have a LiFePO4 battery installed on my 2017 Swift. Different brand from the one in the video. I've been running it since May of 2021 and it is still running strong. Car is my daily driver from Pasig to Laguna and is parked out in the open under the sun at my workplace.

LiFePO4 chemistry is different from the usual Lithium-ion battery. It is not as energy dense but is much safer than standard Lithium-ion. You can spike a LiFePO4 cell with an iron nail and it won't combust.
