hyperion makes the "EOS 0720i NET3 AD" you mentioned above but if you dont mind getting a power supply they also make the EOS 0720i NET3 ....the dc only version. and that one will do 250 watts x1 output that would get you close to 3c charging with a 4s 5000 16.8 volts x 15 amps 252 watts....... that would charge one battery at a time fast, but i would just get the EOS 0615i DUO3 180 watts x 2! that way you can charge 2 battery's at once and still pretty fast and even it its a little slower that the EOS 0720i NET3 dc version at least when its done charging you will have 2 charged battery's not just 1.


most powerful chargers require a power supply...a big one
