Hello Guys,
My charger specification 9.5V@600mA and battery is 2000mAh.
I want to charge two Li Ion series battery with 400mA in some case so i want to limit the current using series resistor.
My theoretical calculation is as per below.
I assume battery is closer to empty state:
R = 9.5V/0.4A = 23.75ohm/3.8W
Now i am not sure what happen if battery voltage increases the charging current deceases. I assume charging time will be increases.
Is there any safety concern ?
Opinion will be highly appreciable.
