Overview
The SkyRC D400 is a twin-channel balance charger/discharger and power supply with two independent circuits, capable of charging two different battery types simultaneously. It supports power distribution in both AC and DC modes to maximise charging power and shorten charging time. A synchronisation mode allows both channels to use the settings from channel 1 for time-saving convenience.
The D400 also functions as a DC power supply, delivering up to 150W on channel 2 to power DC devices, converting 100–240V AC mains to 6–15V DC output. The Charge Master PC software enables real-time monitoring of current, voltage, capacity and individual cell voltage, and supports firmware upgrades.
Note
Connectors with Bare Wires are what we solder onto if you select a different battery connector when adding to cart.
