Learn Moreedit: I will add that if the batteries were placed in parallel, maybe with a 2-series-2-parallel style set up, the current draw would be shared between them better and I most likely would not have experienced these issues. This would have better matched my voltage needs, and provided better current ouput without tripping the protection circuits.
Learn MoreI think in fact it should be possible to use a current limited power supply with a voltage higher than the series voltage. The voltage per cell then is determined by the charge state, as soon as 1 of the cells reach the protection voltage the whole series is disconnected... so it should work like a li-ion charger, first the cells are charged with cc …

Learn MoreYou do not need a full-blown BMS. Your stated charge/discharge currents are way below 18650 ratings (so you can get away without thermal sensor) and parallel …
Learn MoreYes, you can charge 2 lithium batteries in series. This is because when you connect two batteries in series, the battery voltage of each is added together. So, if you have two 3-volt lithium batteries, when you connect them in series the total voltage would be 6 volts where a 3.7 V lithium battery lasts longer.
