Overview

The Spektrum Smart 2S 30C LiPo packs 7.4V and 1400mAh of pure adrenaline, optimized for lightning-fast bursts and sustained performance. Smart technology lets you charge with confidence, automatically balancing cells and monitoring every vital sign. Built-in health tracking and error logging keep you in the know, while the IC2 connector delivers seamless, high-current connections. No more guesswork, just pure, worry-free power to push your RC beast to the edge.

Smart Technology

Ditch the charging complexities and unleash your inner champion with the in built Smart technology. No more endless settings, connect to a Spektrum charger, and the built-in smarts take over. Your battery's unique data communicates through the IC connector, optimising every charge for maximum punch and worry-free life.

Data Driven

Forget guesswork, embrace data-driven power. Spektrum batteries house an intelligent microchip, indicating vital details like brand, chemistry, health, and history. From cell count and C rating to temperature and past incidents like over-charges, this hidden brain lets you make informed decisions on the fly. Gear up for victory with Spektrum Smart technology - where knowledge meets power, one charge at a time.

Auto Discharge

Spektrum Smart LiPos are self-preserving powerhouses. Simply program your desired storage voltage with a Spektrum Smart Charger, and these intelligent batteries automatically discharge down to that level when left idle (between 12 and 240 hours). This clever trick prevents the damaging stress of sitting fully charged, extending your battery's life and boosting its performance for years to come. Think of it as a built-in personal trainer for your power cells, ensuring they're always ready to unleash their full potential.

LiPo Charging: Always use a LiPo compatible charger when charging your Lithium Polymer (LiPo) batteries. Be sure to select the correct chemistry/setting for the LiPo battery you are charging, as charging on the wrong setting can cause violent fires if left unattended. Please use extreme caution and never charge LiPo batteries unattended. We also recommend using a LiPo Safe/Protection Bag while charging your LiPo batteries.
