The SkyRC Ultimate Duo 400 charger is a charger with two independent channels allowing two batteries of different types to be charged at the same time. It allows you to manage the power distribution whether it is supplied with direct or alternating current in order to reduce the charging time as much as possible. It can charge 300W on channel 1 and 100W on channel 2, for a total power of 400W.
Note that the maximum power on channel 2 is 200W and for channel 1 maximum 400W.
In addition, the synchronization mode is available to adjust both channels simultaneously and thus save time when it is necessary to charge identical batteries.
