4000mAh 3S 11.1V Smart LiPo Battery 30C w/ IC3

Spektrum Smart 4000mAh 3S LiPo Battery with IC3 Connector is an 11.1V (3S) 30C high‑discharge power pack designed for high‑performance RC models. It uses Smart technology to store unique data for each battery and relay it to a compatible Smart charger, so charging preferences and battery health are automatically managed and easy to monitor.

Built for durability and heat management, it features a protective outer metal alloy sheet and requires no soldering thanks to IC3/IC5 data‑enabled connectors that remain compatible with EC3 and EC5 systems. The onboard microchip records capacity, cell count, temperature, cycles, and fault history, and can automatically discharge to a safe storage voltage when idle to extend life. When paired with a Spektrum Smart charger, charging is as simple as pressing Start, with the last charging rate remembered for repeatable performance across sessions.
