which budget protected 18650s for upto 7A

Not kept up with which batteries are good buys and I’m struggling to find some protected ones that can do 5-7Amp discharge without issue, any suggestions?

also need some protected high capacity cells that can do 4Amp but are shorter than the panny 3400s.

18650 3500mAh Keeppower 2016 gets up to 10A

The PCB is mainly for low voltage protection

A cell without PCB has still mechanical protection for venting and overcurrent

+1 on the Keeppower 3500mAh. Be aware they are reasonably obese at 18.6mm.
