About this part

Advanced 2S LiPo Battery with Refined SmartFit Case

The Spektrum™ RC 2S Smart G2 30C SmartFit LiPo Battery Pack provides a reliable power source for Arrma Grom or Losi NASCAR platforms with a 30C continuous discharge rating. It uses Spektrum Smart technology to store battery-specific information and communicate that data to compatible Spektrum Smart chargers through its IC2® connector. The SmartFit case also uses tighter tolerances for a better fit within the Grom series.


About the 2S Smart G2 SmartFit LiPo Battery


Smart Battery Management

An integrated memory microchip stores information such as battery type, capacity, C rating, cell voltage, temperature, charge and discharge cycles, and internal resistance. It also records events such as overcharging, over-discharging, and overheating, giving you a detailed record of the pack's condition. When connected to a Spektrum Smart charger, the battery automatically transfers its charging parameters and health information, while customizable charge rates let you set the charging behavior to your preference. Smart Discharge can also automatically bring the battery to a selected storage voltage after a programmed period of 12 to 240 hours, helping prevent the pack from remaining fully charged during extended periods of storage. The factory-installed IC2 connector includes the data connection required for communication with Smart chargers, so no soldering is required.

Features:

  • Provides 1400mAh capacity for Arrma Grom platforms
  • Delivers a 30C continuous discharge rating
  • Stores battery data with an integrated microchip
  • Transfers battery parameters through an IC2 connector
  • Records charge cycles and battery health data
  • Supports customizable charge rates with Spektrum Smart chargers
  • Automatically discharges to a selected storage voltage

IMPORTANT LITHIUM POLYMER SAFETY INFORMATION

  • DO NOT leave a battery in your model when charging
  • DO NOT leave lithium batteries unattended when charging
  • ALWAYS balance charge lithium battery
  • ALWAYS use a LiPo Safe charging bag/box
  • YOU MUST use a Li-Poly specific charger to charge lithium batteries (NiMH or NiCD only chargers WILL NOT WORK!)
  • YOU MUST not over discharge lithium battery packs
  • READ & UNDERSTAND the instructions carefully before operating this battery

NOTE: When using high energy Li-Polymer Batteries, please do not over-discharge or over-charge batteries as this will result in overheated batteries. Discharging capacity can't exceed 80% of the max capacity of the pack after full charging to ensure a good cycle performance. It is recommended to fully charge a brand new battery before using and only discharge the battery 50% for the first 5 cycles. Always monitor race time and/or set a low voltage warning on ESC (End voltage cannot be lower than 3.2v per cell). Do not use a battery that has too low a voltage. Do not expose batteries to sunshine or store/charge batteries at temperatures above 35°C or in a closed car. The high-temperature environment could cause damage to the pack or make it burst. If the battery becomes hot while fast charging, high current discharging, or racing, do not charge it until it has cooled completely. Wait about 20 mins, then inspect prior to recharging.
