Overview

Spektrum Smart G2 50C LiPo batteries offer drivers and pilots enhanced advantages through their Generation 2 features, simplifying and improving safety when used with Smart chargers.

The unique IC connector in the G2 batteries allows for effortless balancing, eliminating the need for a separate balance lead. These batteries also automatically discharge to a safe storage voltage after 72 hours of inactivity, extending battery life and ensuring maintenance-free use.

When connected to a Spektrum Smart charger, Smart G2 LiPo batteries share their charging parameters and health data, enabling convenient customisation of charge rates. This eliminates the need for manual configuration, making charging a hassle-free process.

Smart Battery Technology — One Smart Connection
When linked to a Spektrum Smart charger, a Smart G2 battery's distinct settings, condition status, and balance data seamlessly transfer from its internal memory microchip via the data wire in the IC5 connector. To initiate charging and balancing for the battery pack, you merely connect it to your Smart charger. The safe charging process commences automatically, eliminating the necessity for a separate balance lead.

Data Rich
An integrated microchip allows each Smart G2 battery to save vital information such as battery brand, chemistry, cell count, capacity, number of charging cycles, number of discharges, C rating, battery temperature, and internal resistance. Additionally, each battery will save a log of unhealthy events such as over-charge, over-discharge, and over-temperature. This allows you to make the most informed decision about each battery when you are getting your gear ready to go out and have fun.

Smart Auto Discharge
Spektrum Smart G2 batteries are virtually self-managing. These G2 batteries are factory-configured to autonomously discharge to a secure storage voltage of 3.90V after 72 hours of idleness. The benefits include extended battery longevity, improved performance throughout the battery's lifespan, and the assurance of a maintenance-free Smart battery. Users have the flexibility to customise the Auto Storage settings according to their preferences.

Simple and Quick Charging
The Spektrum Smart G2 battery seamlessly communicates preset charging, discharging, and storage parameters to your Smart charger, simplifying the charging process. You can also tailor the charge rate to suit your needs, optimising the use of batteries with higher charge capabilities. Plus, the battery's integrated microchip remembers your previous charging rate, ensuring it's automatically applied the next time you connect it to the charger.

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.
