SKU CH-W17A-Q3EV5

Two 3.7 V 250 mAh 30 C Li-Po packs add flight time for Syma S107 and S107G drones

  • Longer flights with 250mAh capacity
  • Fits Syma S107 and S107G models
  • Light 0.25 oz cells keep drones agile
  • Stable 3.7V output for smooth control
  • 30C discharge gives quick power bursts

Syma S107 / S107G Li-Po Battery 2-Pack

This 2-pack of Common Sense RC Lectron Pro lithium-polymer batteries is built for Syma S107 and S107G helicopters. Each cell delivers 3.7V and 250mAh capacity with a 30C discharge rating. The pair suits pilots who want longer sessions and a ready spare without adding weight.

Connector and voltage check

Verify that your helicopter uses a single-cell 3.7V Li-Po pack with the same plug as the original Syma battery. Confirm the charger you own is designed for 1S Li-Po chemistry and can handle a 250mAh cell. The battery weighs 0.25 oz (7g), so ensure the airframe balance remains acceptable.

Replaces stock Syma cells

These units replace the factory Syma S107 or S107G batteries when flight time has dropped or a cell no longer holds charge. The 30C rating supports the burst current those helis draw during aggressive manoeuvres. The upgrade is worth it when you need consistent voltage through the full discharge curve and a second pack for continuous flying.
