Product overview

The SkyRC e3S, product code SK-100219, is an AC-powered lithium-battery balance charger. It measures 92 x 58 x 36mm and weighs approximately 104 g. Charging starts when the battery connects through its balance port, providing a straightforward connection for supported packs. The charger accepts LiPo, LiHV and LiFe batteries in 2S and 3S configurations and operates from AC100V–240V at 50/60Hz. Charging current depends on cell count: 2.20A ±10% for 2S batteries and 1.60A ±10% for 3S batteries, both non-adjustable.

Charging power is 20W ±2W, while balance current is rated at 300mA maximum. Storage charging supports LiPo and LiHV batteries, with discharge specifications of 150mA maximum and 2W. LED patterns identify standby, charging, charge completion, storage mode and storage completion through alternating red/green flashes, pulsing or steady green, and pulsing or steady yellow. The charger’s operating range is 0°C to 40°C with 5%–75% RH, non-condensing. Its storage temperature range is -10°C to 70°C.
