So I have done some more research and this is what I have come to understand: (please correct me if I am wrong)
1. Since all of my cells have their own protection circuit, arranging them to charge in series won't cause a dangerous situation. They will only charge until the weakest link is full, thus cutting the circuit.
2. Similarly, discharging them should be safe too, I would just lose max efficiency since my batteries will discharge until the weakest one reaches its cutoff voltage, thus cutting the circuit.
3. Wiring/charging in parallel seems to be ok, due to the same age/same battery set up I will use. I just need to make sure my batteries are fully charged before wiring them up to avoid any big current shifts (which the protection circuit should catch anyway though, right?) I also understand the C rating for charging, and all of my charging options will be at a 0.6C max, assuming my battery ratings are true.
I have an old laptop and the battery is 14.8v with a balancer circuit built in so I might rig that up for charging. The AC adapter has too high of current though, so I plan to run an 18v 0.8a adapter to the circuit. This should be ok right?
