Pre-Owned Hyperion EOS 720i Super DUO3 multi-chemistry charger and discharger system. Includes cable to connect to power supply, and one balance/support only, the unit works excellent. Dual independent ports, each capable of 500W power, for a total of 1000W charging capacity. The system includes integrated balancers and supports a wide variety of battery types, including LiPo, LiFe, Li-ion, NiMH, NiCd, and Lead-Acid. It offers a "sync mode" to balance charge between two batteries simultaneously, making it suitable for high-power RC hobby applications. See all photos, text message is better, see my other adds, thank you.
