Good point. I decided to top balanced in parallel but I got a little greedy and set the voltage to 3.7 5A. This turns out to be the 100% setting of my dc variable charger, which increased the voltage as the battery also reached a higher voltage.
tl;dr: stick with 3.6V b/c the charger won't stop increasing the voltage
EDIT: used the UNIROI 5A dc variable charger https://www.amazon.ca/dp/B07D279WR8/ref=emc_b_5_t
Did anyone read the reviews photo on this power supply showing a 1 Volt peak to peak high frequency noise on this sucker!
Just thinking.....what would that mean to your battery charging adventure. They would act like a big capacitor to flatten out the noise...... but ..........
