power supply for charger

[Cuong44]

i am P3A user.
The charging and balancing circuitry is built into the battery itself. All we need to charge the battery is that provide power to the battery ( pure sine waves ).
the original charger is 57W, it takes so long to get battery fully charged (+80minutes), and one a at time.
i am going to charge 2 or 3 batteries at once.
i intend using this combo : Power supply 24V 50A, cellpro powerlab 8, DC-DC step down converter ( 24V to 17.4V).
using PL8, i can adjust current (up to 30A) to get current output, then it goes through step-down converter, then i have 17.4V and current that provided by PL8 (higher 24/17.4 times actually).
Then i use this current, 17.4V x.A as original P3A's charger to charge the battery.
Will this combo work without any damages for the battery or fire something.

Hi Cuong44

You said "The charging and balancing circuitry is built into the battery itself. All we to charge the battery is that provide power to the battery ( pure sine waves )." you probably just made a typing error, The DJI charger requires a sine wave input, the battery itself requires a DC input .

The current output from step-down converter is DC. It is 17.4V

I'm curious about this also, I have a Celpro powerlab 6.
