Helios RC: 2S 850mAh 45C LiPo (EC2 Connector)

Power your RC adventures with confidence using the Helios RC 2S 850mAh 45C LiPo, a compact and efficient battery designed for high performance in a small form factor. Engineered with Helios RC’s trusted quality and reliability, this 2-cell (2S) lithium polymer pack delivers the perfect balance of power, weight, and durability for micro-sized RC aircraft, helicopters, cars, and drones.

With a typical capacity of 850mAh and a voltage of 7.4V, this battery is ideal for compact models that demand high energy output without excessive weight. The 45C continuous discharge rate (38.25A) ensures a steady and reliable current delivery, while the 90C burst rate (76.5A) provides quick surges of power when your system needs it most—ideal for quick throttle punches, high-G maneuvers, or steep climbs.

The compact design—just 59mm x 30mm x 15mm and weighing approximately 50g—makes this battery easy to mount in tight battery compartments, especially in lightweight or micro RC setups. The EC2 connector offers a secure and consistent power connection, and is commonly used in Horizon Hobby and E-flite products.
