About this part

Battery Overview:

Traxxas Certified iD-equipped LiPo batteries provide the punch and on-demand power to reach the top speeds that Traxxas models are built to deliver. Traxxas’ exclusive iD battery system is the easier and safer way to charge your Traxxas batteries.

Features:

  • Traxxas Power Cell LiPo batteries are designed to fit Traxxas models so you get the most capacity possible.
  • Traxxas Power Cell LiPo packs use a unique construction method that results in a firm, rugged, and compact pack
  • Constructed from high quality materials Traxxas batteries provide consistent performance you can count on.

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.

Would give it zero if allowed to. Battery took 1 charge and was used once and now gives a flashing red fault light on the Traxxas charger. Zero damage to battery and it won't charge.

Good battery and has good run time. I have a couple of these and they work good.

Works perfectly. I got one with the Traxxas Bl-2s deal. It is the same size as the Traxxas 5000 mAh LiPo battery pack. I would recommend getting the 5000 mAh because it will give you a longer run time. I've charged it on an EZ-Peak Live Dual with no problems. That charger does give me some issues with older batteries though, but not with this battery.

What reviewers say

Reviewers of the Traxxas 2S Power Cell 20C LiPo (7.4V/3000mAh) with iD connector are split. Two reviewers, one of whom owns several, report good run time and reliable operation, including charging on an EZ-Peak Live Dual. One reviewer reports the battery failed after a single charge and use, with the Traxxas charger showing a flashing red fault light and the battery refusing to charge. One reviewer suggests the 5000mAh pack for longer run time, though that is a different product. The sample is small, so the reported failure may be an isolated case.

  • + Good run time
  • + Works reliably
  • + Compatible with EZ-Peak Live Dual charger
  • − Charger fault light and will not charge after one use
  • − Single report of early failure
