No, it just means it can do current constant and voltage constant (almost every power supplies can do this) not a shape CC CV for Li-ion.Gregory wrote:Just looking at the picture it looks like it will do CCCV
What a relief that we finally got someone on this forum who understands Li-ion charging!alexis57 wrote:Another way to explain you, the CC CV shape is : (recommended for li-ion battery in order to get a full recharge)
With your power supply (which isn't a CC CV charger but a simple DC power supply) and you stop at 4.2V (then you do only the phase I), where is the energy of the phase II ? The one you don't provide to the battery ?
Don't they turn off when current reaches some low value? If they turned off on final voltage, you wouldn't have CV phase at all.dnmun wrote:a power supply does not turn off. not sure who started this misinformation but it is totally bogus.
there are some chargers with the label 'smart charger' which have a latching output that does turn off when the charger reaches final voltage. they should not be used with a lifepo4 pack with balancing BMS.

Hmm. Then what, for you, is the distinction between a power supply and a non-smart charger?dnmun wrote:a power supply does not turn off. a charger does not turn off at the end of CV.
How does one know whether one's charger is smart or not? I think for a lot of us, when we hear "charger", the first thing that comes to mind is Kingpan, which isn't particularly smart compared to a Satiator, but it does have a low-current shutoff, right?a charger only turns off it has the latching output as is the case of the chargers called 'smart chargers'.
OK, suppose you're an electronics hobbyist and you dial this supply down to 5 V to power a circuit on your breadboard. Do you think this supply would refuse to provide any power unless your circuit was pulling current at the current limit?alexis57 wrote:doesn't provide any current anymore when the voltage battery reached the power supply voltage
A charger (or smart charger, in dnmun's parlance) will do this automatically. A power supply will do it through the intervention of an attentive operator.A Li-ion charger HAS TO turn off when the current at the end of the CV phase is too low !
