1300mAh 11.1V 30C 3S Smart G2 LiPo Battery Pack with IC3 Plug (SPMX133S30)

Spektrum Smart G2 3S 1300mAh LiPo Battery with IC3 Connector is a compact 11.1V power pack designed for RC cars, boats, and planes. With a 1300mAh capacity and a 30C rating, it delivers dependable bursts of power when you need it. The IC3 data wire carries balancing information to a Spektrum Smart charger, so charging and balancing happen over a single connection—no separate balance lead required.

Inside the soft-case pack sits an integrated microchip that stores key details such as brand, chemistry, capacity, C rating, per-cell voltages, temperature and cycle counts, plus a log of events like overheat or over-discharge. When connected to a Spektrum Smart charger, those parameters upload automatically and the charger applies the optimal charge settings. The design includes thicker internal metal side plates for improved heat dissipation and cell protection, and the battery auto-discharges to a safe storage voltage of 3.90V after 72 hours of inactivity (storage discharge is three times faster than the previous generation). Auto Storage settings can be customized, IC3/IC5 connectors stay compatible with EC connectors, and a Spektrum Smart charger is required for full Smart features.
