What kind of capacity from your LFP battery? Is it diy built? I did one in the spring 16S with 25Ah cells and it's been amazing since. Only problem is it's a bit too big to fit anywhere I'd like it to. I have to mount it on a rear rack

I am using 3x 12v 185wh batteries in series. Realistically I can count on around 500wh. They are only 3 lbs each and fit neatly within the frame of the mtb. I don't like having them up on the rear rack, they tend to make the tail of the bike wag a bit compared to low and centered.

I just 3d printed protective covers for them last week when marketing turned their back on the new Bambu printer.

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?
