I am charging 2s and 1s batteries most I ever charge at it 2c! I run 7800mah 1s, 6400mah 2s.

I have 2 chargers set up for 2s and 2 for 1s I only ever charge 1 battery per charger at the track...

Thoughts on the two options?

The Fantom should be just about right for what you are asking of it. Assuming a mildly conservative 80% charger efficiency around 36 amps is needed from a 12V supply with all 4 chargers going as described. Leaving a little more than 20% of power supply headroom.

If you do consider the Chargery unit in case of future needs etc, be sure to not turn it up past 18 volts with those chargers.
