Actually, running through an MPPT charge controller can get more watts into the battery than directly connecting the power supply to the battery, because the supply is limited in output amperage, but should be able to up the voltage to 30 or more, and the cc can regulate that down to battery voltage.
In the initial stage of charging when the battery voltage is low, charging is performed at a constant power, and when the battery is close to full charge, operation switches to CV charging to
Constant Current Constant Voltage Battery Charger Home. Forums. Hardware Design. Power Electronics Constant Current Constant Voltage Battery Charger I think a switching power supply would do the job with 1W of power loss. I can''t remember how to add current limiting to this.

It''s worth noting that this behavior is often desired for things such as battery-charging; many lithium battery charge curves refer to "CC-CV" charging, where you charge at a constant current until the voltage reaches a setpoint, and then charge at constant voltage while the current drops due to the cell becoming more and more charged.
Charger is controlled via charger regulator pcb. I can see that battery voltage during charging is 240 volts. 15 volts per each battery. Battery current is 3 amps during charging. It looks like overcharging. Also batteries are swell up. (I use a separate constant voltage power supply set at 13.8V) I suggest to initially charge the batteries

For effective battery charging, especially with lithium-ion and lead-acid batteries, the Constant Voltage/Constant Current (CVCC) method is recommended. This approach allows the power supply to maintain a steady voltage while the current can vary according to the battery''s state of charge.
In this stage, the charger supplies a constant voltage to the battery. The purpose of this stage is to slowly top off the battery so it doesn''t overcharge and become damaged. Once the battery reaches its full capacity, it will stop accepting any more power from the charger and enter standby mode. 4 Stages of Battery Charging .
I''m using this LED Driver (constant current, output range 143-286v) to balance charge a high voltage hybrid vehicle battery at very low current, and it works pretty well. I''ve got a diode on the output to prevent back feed from the battery, a dropping resistor to bring the output close to the battery''s nominal voltage as well as a 100k Ohm

A DC voltage of 2.30 volts per cell (float) or 2.45 volts per cell (fast) is delivered to the terminals of a sealed lead acid battery to charge it. Can I use a 12V power supply to charge a 12V battery? A 12v battery cannot be charged with a 12v power supply because the charging voltage must be higher than the battery voltage. Charging a lead
It will not automatically turn off when charging current has dropped low enough to end the charging cycle. Same applies to the constant current power supply. It will push constant current into battery until battery voltage rises high enough so the supply can''t output constant current any more.
When the battery voltage reaches to 4.0 V then a Constant Voltage equal to the maximum rated voltage of the battery i.e. 4.2 V must be provided to it. The battery charging current then should start decreasing and when it reaches to 0.1 C i.e. 100 mA, then the battery must be considered fully charged.

There are three common methods of charging a battery: constant voltage, constant current and a combination of constant voltage/constant current with or without a smart charging circuit. Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage.
When the discharged battery (at 15V) is connected to the power supply, the battery will start to charge at the pre-set constant current level. The current will remain constant until the voltage rises to 28V. At this point the power supply will transition to constant voltage mode and the current will decay to zero when the battery is fully charged.
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.
Constant current charging is a way to charge common batteries. This is a charging method where batteries are charged with a constant current from beginning to end.
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Charge times are relatively long with the disadvantage that the battery may overheat if it is over-charged, leading to premature battery replacement. This method is suitable for Ni-MH type of batteries.
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Constant current/constant voltage is a combination of the above two methods. The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level.
