Cell voltage never over 3.8V? Bad idea or ok?
Yes, I just tested a 100p cell from 3.8V to 4.0V. In this voltage area I have around 50Ah what is equal to 1/4 of the capacity from 3.3V to 4.0. But if it would still make my cells live longer it''ll be fine. 3.3V to 4.2 Volts is also much more capacity.

Lead Acid Battery Voltage Charts
Apply a charging voltage of 2.30V to 2.45V per cell, depending on the battery type. Gel and AGM batteries need voltages at the higher end. Reduce the voltage by 3mV per cell for every 1°C above 25°C. Increase by 3mV per cell for every 1°C below 25°C. Finish the charge with a lower float voltage around 2.25V to 2.30V per cell.
