The large size LiIon battery with more capacity than rated.
The two batteries tracks fairly well, but the over current protection is a bit low, it trips the 5A trace.
The cells used looks good, but the protection current limit is on the low side, and the battery does not have that great performance at a couple of ampere, compared to other 26650 batteries.
