The Hyperion EOS0730iNET3 is the ideal charger for those charging battery packs up to 7S.
With an astonishing charge capability of 30Amps / 550W output it is possible to speed charge even larger lipos packs at 5C - a great example would be a 5000mAh 6S pack which could be refuelled in under 20 minutes.
The EOS0730iNET3 requires a 24V-29V power supply to make full use of the potential. At this input voltage the charger performs at a higher efficiency which allows for these performance levels. Of course you can still use any power supply form 10.5V. The performance is around 300W at 13.6V.
