Spektrum Smart G2 Trail Pro 11.1V 3400mAh 3S 50C LiPo Battery (SPMX-1047)

Spektrum Smart G2 Trail Pro LiPo Battery is a high-capacity 11.1V (3S) 3400mAh pack designed for RC crawlers and scalers that demand steady, long-lasting power. Built with Spektrum Smart technology, it maintains strong voltage through heavy loads and communicates with a compatible Smart charger to simplify charging and provide battery-health data, helping ensure consistent performance over the life of the pack.

The semi-hardcase is thinner, allowing more capacity to be packed into a crawler-ready footprint while still protecting the cells in rough terrain. With a 50C continuous discharge rating and a 3C maximum charge rate, it delivers responsive power and faster charging when used with a Smart charger. The battery stores extensive data—capacity, C rating, individual cell voltages, temperature, and charging cycles—and logs events like overheating or over-discharge, helping manage packs with confidence. It also features Smart Auto Storage, automatically discharging to a safe 3.90V per cell after 72 hours of inactivity, for longer life and reliability. The integrated microchip communicates with the charger to apply preset charging and storage parameters automatically, making setup quick and safe.
