Trail Pro 14.8V 1280mAh 4S 50C LiPo Smart G2 Battery Pack with IC3 Plug (SPMX-1048)

Spektrum Smart G2 Trail Pro LiPo Battery is a 14.8V (4S) 1280mAh high-capacity LiPo pack designed for RC crawlers and scalers. It maintains high voltage through heavy loads for longer runtimes and strong, consistent power on tough climbs, with a 50C discharge rating for reliable bursts. The Pro Series uses a thinner semi-hard case that’s lighter and more compact yet rigid and impact-resistant, letting more capacity fit into tight crawler chassis. When paired with a Spektrum Smart charger, a data connection lets the charger read the battery’s health and settings for a maintenance-free charging experience.

Smart Trail Pro batteries feature automatic storage discharge to 3.9V after 72 hours of inactivity, helping extend pack life and preserve performance. The integrated microchip stores essential information such as brand, chemistry, cell count, capacity, C rating, per-cell voltage, temperature, and charge/discharge cycles, plus a log of events like overheating or over-discharge. Connected to a Spektrum Smart charger, these details upload to automatically apply charge, balance, and storage presets, delivering safer, faster charging and longer-lasting power for trail runs.
