650mAh 7.4V 30C 2S Smart G2 Hardcase LiPo Battery Pack with EC2 Plug (SPMX652SH2)

This Spektrum Smart G2 2S LiPo hardcase battery pack delivers 7.4V, 650mAh with a 30C rating, providing compact, reliable power for RC models. The rugged hard case protects the cells during use and transport, and the pack is available with EC2 plugs or an IC2-enabled variant to fit common charging setups. Smart G2 technology uses the IC2 data wire to pass balancing information to a Spektrum Smart Charger, enabling safe, streamlined charging with a single connection when appropriate.

Inside, an integrated microchip stores essential battery data—brand, chemistry, capacity, cell count, C rating, individual cell voltages, temperature, charge/discharge cycles, and logs of safety events—so the pack helps you pick the right battery and monitor health. The G2 design also pre-programs an automatic storage discharge to a safe 3.90V after 72 hours of inactivity, helping extend life and maintain performance. When connected to a Spektrum Smart Charger, the charger reads the battery’s parameters and health data, so charging preferences can be set automatically, while the hard case protects the pack in storage and travel.
