It's not rocket science.If on the other hand, you want rocket science:Use two 18650 rechargeables.
The two 18650's packs quite a punch!
I have 5 of those wired in parallel in a phone charger pack
I feel like this stopped being about my question a long time ago.
Darn I better tear down all those solar powered sites that I have put in the last 20 years as the batteries are all in parallel.
When someone asks for help I assume it is practical help they want, not theoretical help that postulates impossible conditions.

As for paralleled cells, I've seen a lot of battery packs with rechargeable lithium ion or lead acid cells in parallel. But those are rechargeables. Different situation.
Batteries connected in parallel should be at the same state of discharge. If batteries at different states of discharge are installed into a device using a parallel battery configuration, the battery with the higher voltage will charge the battery with lower voltage until voltage equilibrium is reached in the system. This charging could lead to leakage, elevated temperature, or other damage to the lower voltage cell.

Be happy that you got a good answer, then lean back and enjoy, as the thread takes off in whatever direction it chooses.That's just the way it is
