No idea how you are working out your requirements

8.4v (2s lipo fully charged) x 5.2 amps requires 44 watts, allow 20% for inefficiencies makes 53 watts or so

Assuming the charger is capable of producing 53 watts it would require a supply of

53 watts divided by 12v (PS voltage) = 4.4 amps or so


If you wanted to use 2 identical chargers to charge the same size packs you would need at least 8.8 amps

Cheers
Thanks, yes. I messed up and used 3s packs. It is indeed 88 watts. I edited my post to be accurate. (a cheaper ps is great)
