Would it be possible to charge a 18650 Li-ion with a Lab (bench-top) power supply? The power supply I have access to is voltage regulated with an adjustable current limit. I was thinking of setting the voltage at 4.2v and current limit at 0.5C (~1A). That way the current limit would hold the charge current at 1A until the current draw decreases. Then the power supply would hold steady at 4.2v for the remainder of the charge. I could then manually cutoff power when charge current drops below 0.1C.
I'm still rather new to Li-ion batteries though, and I'm not sure if this would be a safe way to charge the batteries. Any advice would be appreciated.
