that R4 is used in the SOC feedback loop that varies the charging terminal voltage in accordance with the battery’s present state. Lowering the value of R4 to 15K or less will have the effect of increasing the mode differential voltage. Initially the battery will be charged at high current levels and the terminal voltage of the charger will be pulled low by design. When the battery begins to draw less current, the terminal voltage will gradually increase to the maximum determined by the value of R4. Using a higher ‘Charge’ voltage will decrease your charging time but you must keep in mind that cell gassing normally begins at 14.4V and higher at 25°C, so doing this is risky. Great care should be taken to avoid possible gas
3)Another point to cover is the type of
