OVONIC X4 500W 4-Channel AC Smart Charger

The OVONIC X4 is a four-channel AC balance charger with 500 W total output, for pilots who charge several 1–6S packs at once: FPV quads, RC cars, planes and boats. Power is shared dynamically, giving up to 250 W per channel with one or two channels in use, 167 W across three and 125 W across four.

Key features

• Charges LiPo, LiHV, LiFe and Li-ion from 1S to 6S, plus 3–18S NiMH and NiCd
• Up to 15 A charge current per channel and 1.2 A balance current per cell
• Synchronous rectification for up to 98% conversion efficiency and less heat
• 3.5-inch IPS colour screen shows voltage, current, internal resistance and capacity for each channel
• Protection against over-voltage, reverse polarity, short circuit, over-current, overheating and cell mismatch
• XT60 outputs with an adapter kit to EC5, XT30 and T-plug included; physical buttons work with gloves on
