5000mAh 11.1V 30C 3S Smart G2 Hardcase LiPo Battery Pack with IC5 Plug (SPMX53S30H5)

Spektrum Smart G2 11.1V 3S 5000mAh 30C hard-case LiPo battery is built to power RC cars, planes, boats, and other models with reliable, high‑current performance. It uses Spektrum Smart G2 technology to simplify charging, communicating balancing information through the IC3 or IC5 data wire so charging can be done with a single connection and no separate balance lead is required.

Inside, an integrated microchip stores battery‑specific data such as capacity, C rating, per‑cell voltages and temperature, plus a log of events like overheating or over‑discharge. Thicker internal side plates improve heat dissipation and cell protection, while automatic storage discharge helps extend life by reducing voltage after periods of inactivity. The Smart G2 system can recall the last charging rate and supports discharge up to 1.5A for safe storage; a Spektrum Smart Charger is required to access these features, with IC3/IC5 connectors compatible with EC connectors for broad compatibility.
