RCDrone 1S LiPo Batteries | 3.7V, 25C, 220

Overview

Choose a single-cell replacement battery for a compatible RC helicopter, quadcopter or model airplane. Select the model code and capacity first, then match the connector and wire polarity to the original pack.

Features

The flat lithium-polymer pouch fits compact battery bays. Packs with the same capacity can have different dimensions.
The source rates the series at 25C discharge. A two-wire lead connects the pack to the aircraft or a compatible single-cell charger.
Models from 802030 onward are listed with a protection board for overcharge, overvoltage, overcurrent and short circuits. The individual 702025 and 702030 listings do not confirm a board.
