Changing to a DC supply will not make a difference unless the charger has different power rating for AC / DC

If the charger is rated at 50 watts you will get nowhere near 5 amps with a 4s battery pack

Amps = Watts / Volts

Assuming your pack starts at 12v you will see 4.16 amps at the start, and it will get lower as the voltage rises

50 watts divided by 16.8v = 2.97 amps (at the end of the charge when pack is full)

Cheers
