A 20650 battery with not that much capacity for the size, how much current can it deliver?
These discharge curves do not look very good, the batteries are a bit mismatched and they can barely deliver 7A.
At least they stay fairly cool.
When batteries get larger I generally expect more capacity or more current, or even both, but this battery has less of both. A good 18650 has the same capacity and can deliver more current
