Description
Overview
The Renogy Core Mini 300Ah packs a lot of capacity into a light, compact case: at 55.1 lb (25 kg), one person can carry it. Renogy says it’s 31% smaller than its counterparts and fits common battery boxes, including 8D and 4D sizes.
One 300Ah battery replaces a three-battery setup with two simple cable connections and no cell imbalance between batteries. The built-in BMS cuts off charging automatically in low temperatures.
