The lifepo4 battery ontario question that most property owners get wrong is whether the $280 price difference between a Chins 100Ah and a Battle Born 100Ah heated LFP represents a real specification difference or just brand premium, because a cottage owner in Northumberland County installed a Chins 100Ah to save that $280, confirmed via SmartShunt
