A 16,000 mah battery rated at 5C continuous will supply 80a continuous. By spec anyway, no idea if it’s real or not.

Capacity x C rating = Current rating

16Ah x 5C = 80A as Dave said.

I’ve used those Foxtech Dimond batteries a good bit, they have performed well and have unmatched energy density as far as I know. I have only used them at 2 or so C continuously though.

Yes, my friend said the same. In this case I think you do get what you pay for.

Discharge curves given to me by their customer support:

Admirable that they supply comprehensive data.
