A fully charged Lithium is 4.2V. Just power it from 5V USB, with a standard 1n4001 diode in series to drop a volt. You might need an electrolytic capacitor across the battery place e.g. 1000uF to reduce noise and supply peaks. (batteries have a low impedance, and it has only 3" of wire) Brilliant! Why didn't I think about this?
Say half an hour, then 24 V 24+ A supply. Replacing a battery from a battery-operated equipment with a power supply can be tricky. Especially when the equipment uses an electric motor. The problem is that an electric motor can draw very large startup current - it can be as 10-20 times the nominal for a couple of seconds.
First set the voltage and current (i.e. 14.6V 5A) and then press then press the output button. It will charge at 5A (constant current - CC) until it reaches the target voltage, then it will switch to constant voltage (CV). The current will then taper down to nearly zero when fully charged. Sure you can. I have a PS similar to the one on the right.
This is a charging method where batteries are charged with a constant current from beginning to end. A standard switching power supply is a constant voltage power supply, so it monitors fluctuations in output voltages, inputs the results in the control circuit, and executes constant voltage controlling also known as feedback controlling.
The most appropriate method for charging batteries among them is with a power supply that has constant current voltage drooping type characteristics (Far Left) where a constant current range is used for charging batteries with a constant current. The other two characteristics should not be used to charge batteries.
The two main chemistries for conversion are LifePO4 (LFP) and Lithium Nickel Manganese Cobalt (Li-NMC). Lithium-ion batteries have a BMS (Battery Management System) built into them. This means that the battery will automatically prevent itself from becoming over-discharged or overcharged.
