Charging current/voltage for lipo batteries
I have a 500mah 1S lipo battery. I wanted to charge it with my lab bench power supply. Easy, I thought: I want to charge at 2C (which is 1A) so I simply set my power supply to 4.20V and 1A limit and To charge any lithium based battery you generally should not be using a bench power supply unless it has a special "Charge lithium based cells" function.
Battery power explained
Power = voltage x current. The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for.
How to Calculate the Battery Charging Time & Battery Charging Current …
So charging current for 120Ah Battery = 120 x (10/100) = 12 Amperes Suppose we took 10 Amp for charging purpose, then charging time for 120Ah battery = 120 / 10 = 12Hrs. but this was an ideal case… Practically, it is noted that 20%-40% of losses (in case of battery charging). we suppose 20% loss
