7.4V 4000mAh 2S 30C Smart LiPo G2 Hard Case: IC5

Spektrum Smart G2 7.4V 4000mAh 2S 30C LiPo Battery with IC5 Connector is a high-capacity pack designed for Spektrum-enabled RC vehicles. It delivers steady power at 7.4V with a 30C continuous discharge and is equipped with an IC5 data-link connector that communicates with Smart Chargers for safer, automatic charging.

Inside, a microchip stores essential data such as battery brand, chemistry, cell count, capacity, C rating, individual cell voltages, temperature, and charging cycles, and it logs events like overheating or overdischarge. When used with a Spektrum Smart Charger, this information uploads automatically, allowing the charger to apply preferred charge rates and monitor battery health. The Smart Discharge feature automatically brings the pack to a storage voltage after idle periods (12–240 hours), helping extend life, and the memory keeps your last charging rate for quick, consistent setups.
