What happens if a battery reduces OCV and R_Batt?
IMPORTANT: The reduction of OCV and/or the increase of R_batt cause the reduction of the fault current provided by the battery. Example: For the VRLA type battery close to the End of Discharge (EOD) and End of Life (EOL), due the OCV reduction and resistance increase, the short circuit current can be around 60% of the nominal short circuit current.
How do I reduce a battery charge voltage?
Place 4 diodes in series with the 5V output, reducing the charging voltage to 2.4V and add a 2.7V zener diode across the battery pack to prevent the charge voltage increasing above this as the charge current drops towards zero. A series resistor is all you really need, based in what you said.
