5000mAh 11.1V 100C 3S Smart G2 Hardcase LiPo Battery Pack with IC5 Plug (SPMX53S100H5)

This 5,000mAh, 11.1V (3S) hardcase LiPo battery with an IC5 plug is built for high‑drain power in RC cars, boats, and other hobby models. It features Spektrum Smart G2 technology and a 100C continuous discharge rating, delivering strong, dependable punch when you need it most. Balancing information travels through the IC5 data wire, so charging is as simple as plugging into a Smart charger with a single connection rather than a separate balance lead.

Inside, a microchip stores essential battery data—brand, chemistry, capacity, cell count, C rating, temperature, and cycle history—and logs health events to help you choose the right pack for each run. The pack uses thicker internal metal side plates to improve heat dissipation and cell protection, and it automatically discharges to a safe storage voltage after 72 hours of inactivity, helping extend life and maintain peak performance. For charging, connect to a Spektrum Smart Charger (or an older Smart Charger with G2 update); the Smart system handles charging parameters automatically, with no extra setup required beyond the single IC5 connection.
