Spektrum 11.1V 4000mAh 3S 30C Smart G2 Hardcase LiPo Battery – IC5 (2S Form Factor)
Get 3S power in a 2S-sized package with the Spektrum 11.1V 4000mAh 3S 30C Smart G2 Hardcase LiPo Battery. Uniquely designed to match the physical dimensions of a standard 2S hardcase pack, this battery is the ideal solution for drivers with 2S battery compartment size limitations who want to step up to 3S performance without chassis modifications. The custom-tailored size, shape, and 30C rating make it a purpose-built solution for compatible vehicles where standard 3S packs simply won't fit.
Smart G2 technology ensures charging is as straightforward as it gets — connect to your Spektrum Smart charger and Auto Charge begins immediately, uploading the battery's unique parameters and health data automatically through the IC5 connector's data transfer wire. Preset charge, discharge, and storage settings load every time the pack is connected, and your last custom charge rate is stored in the integrated microchip so it's applied automatically on the next session. Smart Discharge automatically brings the pack to your preset storage voltage after 12 to 240 hours of rest, protecting cell chemistry and extending overall pack life without any manual intervention. The rigid hardcase construction shields the cells from impact and puncture during hard surface use, and the onboard error log tracks overcharge, over-discharge, and overtemperature events for complete pack health visibility.
