What voltage to re-charge stacked 18350's

[Zig Srq]

Does any one know the ideal voltage to remove my stacked 18350 batteries and put them back on the charger? Seperately, fully charged they are about 4.1 volts. Together about 8.2 or 8.3. I guess I want to know "How low can I go"? They are Efest 3.7 800 mAh

There is going to be a whole lot of information thrown at you in a few minutes. If you are not sure of what you are doing with stacked batteries, don't stack them. Now I will get out of the way and let the experts explain why.

It may also help to know on which device you are using the batteries.

I recognize that the batteries can have different voltage in them and understand that 7.2 volts total does not mean each battery has 3.6 volts in it. So should I ask, at what voltage should I recharge the individual battery? I do not use them individually and have been putting them back on the charger when they are at about 3.4 volts each Can I use them longer?

3.45 or 3.5 volts is probably a good point to recharge them.

Ok, Thanks!
