For compatible 2S and 3S packs, keep the charging routine simple rather than adding another menu maze to the bench. The SkyRC e3S charges LiPo, LiHV and LiFe batteries through their balance connection, with 20W rated charging power, a single MODE button and colour-coded status LEDs.
Key Highlights
Balance-port charging: Dedicated 2S and 3S connections keep setup straightforward. Connect one battery at a time, never both ports together.
Three lithium chemistries: Select LiPo, LiHV or LiFe to match the battery. Similar-looking packs are not permission to guess the setting.
Fixed current, fewer settings: The e3S uses 2.20A for 2S or 1.60A for 3S, each with 10% tolerance. Check that your pack permits this current before connecting.
LiPo/LiHV storage mode: A separate storage function prepares supported packs for downtime. Its 2W discharge capability is modest, not a fast way to empty a full pack.
Compact mains-powered design: A 92 58 36mm case and approximately 104g charger weight leave room for the rest of the bench clutter.
Why You Want It
If your routine centres on supported 2S or 3S lithium packs and their charge-current limits suit this charger, the e3S gives you a focused charging and storage option without an external DC supply. It is not a universal FPV charger: 1S whoop batteries and 4S6S packs need another solution, and small packs may need a lower, adjustable current.
Specifications
Manufacturer model: SkyRC e3S, SK-100219
Input: AC 100240V, 50/60Hz
Input power: 25W 10%
Supported batteries: LiPo, LiHV and LiFe; 2S or 3S
No. The chemistry, balance connection and battery manufacturer’s permitted charging current must all match. The fixed current cannot be turned down for a small pack.
Can I use both balance ports at once?
No. SkyRC explicitly warns that connecting 2S and 3S batteries simultaneously may damage the charger. Use one pack at a time.
