Overview
DuoHeat Tech uses 110W of dual heating pads to warm every cell. It switches on automatically at 41°F (5°C) and off at 50°F (10°C), and Renogy says it brings the battery to ready-to-charge from as low as -22°F (-30°C) in about 60 minutes.
Each battery has over 25 safety features and is rated for 5,000+ cycles at 80% depth of discharge, in a package 45% smaller and 11% lighter than standard batteries.
