3.6V max. Use a lipo balance charger, don’t always use the balance function. It’s an A123 pack that was barely ever cycled. Worst I’ve seen the cells is 14mV when one hit 3.60. The others weren’t too far behind.The point of the BMS is not the pack voltage, it's the cell voltages...
In your 20 amp hour pack, what are the cell voltages when the pack is at 14 volts? Any of the individual cells over 3.6 or 3.7 volts? it's the individual cell safety and health that is the point of using a BMS.
Edit. Oh you were asking at 14V. 3.50V with typically an 8mV deviation
