Nice

I have a big commute and in the (Canadian) winter my old 750Wh was sometimes not up to the task. So I went wildly over the top and built a huge cap battery. I never need to worry now

I don't plan to bike commute in the winter, it is too dark AM and PM. Have you tested your LiFePO4 batteries in low temperatures?
