SkyRC e4Q

The SkyRC e4Q is a compact, four-channel LiPo balance charger for preparing drone batteries. It charges 2S, 3S and 4S packs through independent balance-port connections, with selectable 2 A, 3 A or 5 A current. An XT60 DC input, colored status indicators and audible completion alarm support its charging workflow.

Product overview

The SkyRC e4Q, product code SK-100140, supports charging preparation for drone batteries through four independent, identical circuits. Each channel accepts a 2S, 3S or 4S LiPo battery, allowing four batteries to charge simultaneously. Its physical format measures 128 × 128 × 50.5 mm and weighs 280 g net. Batteries connect through their balance plugs to specially designed output interfaces, with direct connection for the supported cell counts and no transfer board required. The hardware is a battery charger, with a DC power input and four charging channels.

Integration requires an 11–26.1 V DC supply connected through the AMASS nylon XT60 input. Charge circuit power is specified as 4 × 50 W ±10%, with button-selectable currents of 2 A, 3 A or 5 A. Balance charging uses a saturation voltage of 4.20 V ±0.02 V per cell and a maximum balance current of 400 mA per cell. Colored LEDs identify current and charging progress, while an audible alarm accompanies completion. Operation is limited to 0–40°C and 0–75% humidity; protection covers short circuits, overcurrent, reverse polarity and DC input voltage.
