About this part

The Spektrum RC 3S Smart G2 LiPo 100C Battery Pack with IC5 Connector provides pilots and drivers with an array of Smart benefits; Not only are charging parameters and performance data stored and uploaded automatically to Smart chargers, but no balance lead is needed — just one easy IC connection.

Smart G2 batteries come from the factory programmed to discharge automatically to a safe storage voltage of 3.90V after 72 hours of inactivity. The benefits include longer battery life, better performance over the life of the pack, and the peace of mind that comes from knowing your Smart battery is maintenance-free. You can change the battery's Auto Storage settings based on your own preferences. G2 batteries also offer a storage discharge rate that's three times faster than the previous G1 Smart batteries.

Enjoy the Smart Battery advantage of not having to set your own charging preferences. When a Smart G2 LiPo battery is connected to a Spektrum Smart charger, its unique charging parameters and health information upload to the charger from the battery's integrated memory microchip. Through the charger you can view and set preferences such as charge rates, so all that's required to charge the pack is connecting it to your Smart charger. That's the Smart Battery Advantage!

Note: G2 batteries require the use of a Spektrum™ G2 Smart Charger or earlier Smart Charger with G2 update.

Features:
  • Simpler and safer to use
  • Balance charge through the IC3® or IC5® connector data wire — with only one connection, no balance lead required
  • Faster Auto Discharge at up to 1.5A to safe storage voltage for long battery life and improved performance
  • Thicker internal metal side plates protect cells and improve heat dissipation
  • Integrated microchip stores unique parameters for each battery
  • IC3® and IC5® connectors are also compatible with EC3™ and EC5™ styles

Jonathan HogueVerified owneron Spektrum RC 3S Smart G2 LiPo 100C Battery Pack (11.1V/5000mAh)

As per usual, the other reviewer suffered operator error and blames the brand and product, rather than taking responsibility for F'ing things up. This and other RC related websites are subject to allowing those new to the hobby the chance of leaving reviews when they have no idea what they're doing, hence the previous rating on the product page ? NOT impressed. As for the product, here it is... I've been using these smart tech batteries for quite sometime and have been absolutely happy with them. I've yet to get a bad battery out of the box and they've withstood run after run at the track. The Smart Tech is easy to use. Overall, no complaints and a great place to start for new people looking to break into the hobby and experts alike. These are the first of their kind, so kudos to Horizon Hobbies!

What reviewers say

Reviewers offer mixed views on this 3S 11.1V 5000mAh LiPo pack with IC5 connector. One verified owner reports good experience over repeated track use, out-of-box reliability, and easy operation with the Smart system. Another reports that the pack fits a Traxxas SCX6 well, praising the seller's customer service. A third, rating 1/5, reports that the battery could be bricked by the Smart charger with a single button press, and warns against updating the battery with the charger. One review contains a dispute about another reviewer's operator error that is not relevant to the product. Overall, reviews are few and contradictory on reliability, with a specific charger-related concern raised.

  • + Reliable out of the box
  • + Holds up to repeated track runs
  • + Easy to use with Smart system
  • + Good fit for SCX6
  • − Reported bricking via Smart charger
  • − Warning against charger firmware updates
