A 3.7 volt battery charges up to 4.2volts. 20 would be 84 volts fully charged.
3 to 2.5 volts x 20 is 60 to 50 on low endso depends on what range you want and
the max your system will allow.
An A123 is LiFePO4 and they charge to 3.4 volts. 20 is 68 Volts.

I am having trouble deciding weather 20, 21, or 22 batteries are the right
series string for a 72vdc battery. for a 3.7 volt battery 20 seems to be
right. However I have A123 batteries and nominal is 3.3vdc. Videos on YouTube
are inconclusive. Sellers details not complete. Any advice appreciated. I'd
like to run 1 or two strings for a small ebike battery. The controller only
draws 40amps. Lawrence Rhodes
