We choose the most safe LiFePO4 battery type for our expandable battery modules, the materials used inside battery cell will not cause any fire or explosion. The quality of cell is very consistent and can last more than 2000 charging cycles. Its C-rating is 3 times, that means a single 48V50AH module can output 150A continuosly. That's why you can buy just one or two battery modules first, to test the outboard motor performance and get amperage to calculate before you know the exact battery capacity you need.
