4000mah 14.8V 30C 4S Smart LiPo Battery Pack with IC3 Plug (SPMX40004S30)

This 14.8V 4S LiPo pack delivers 4000mAh of capacity with a 30C discharge rating, providing strong, reliable power for high-performance RC models. It integrates Spektrum Smart technology and an IC3 data-enabled connector, so when connected to a compatible Smart charger the battery automatically uploads its unique parameters and health data, letting charging proceed with a simple press of Start.

Inside, a microchip stores essential data such as battery brand, chemistry, capacity, cell count, C rating, per-cell voltages, temperature, and charging cycles, and it keeps a log of events like overheat, over-discharge, and over-charge. A protective outer metal alloy sheet helps dissipate heat, preserve shape, and boost durability, while the IC3/IC5 connector system remains backward compatible with EC3 and EC5 setups for easy integration. When used with a Spektrum Smart charger, this smart pack can automatically discharge to a chosen storage voltage after a rest period (12 to 240 hours), helping extend battery life and preserve performance.
