About this part

Completer Pack Overview:

The 3s LiPo EZ-Peak completer pack is the perfect companion for your Velineon VXL-3s equipped vehicle. The included 5000 mAh 11.1-volt 3-cell LiPo battery provides quick acceleration and ample run time for more fun behind the wheel. The EZ-Peak balance charger is the perfect solution for your charging needs with 5-7 cell NiMH and 2-3 cell LiPo capability. The Traxxas iD system is the easiest and safest way to charge your Traxxas batteries. The charger automatically determines the type of iD-equipped battery being charged and optimizes the charge settings as soon as you plug it in. There’s no guesswork involved, just fast, reliable charging every time!

  • Auto-recognizes Traxxas iD® batteries
  • Optimizes charger settings
  • Charges 5-7 cell NiMH and 2-3 cell LiPo batteries
  • Easy to use interface
  • Advanced Mode for full manual control of charger settings
  • Built-in balance ports for conventional LiPo batteries

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: This battery can only be safely charged with a Traxxas iD Battery Charger. NEVER, UNDER ANY CIRCUMSTANCES, charge this battery using a non Traxxas iD Battery Charger. 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.

  • (1) 3S 25C LiPo Battery (11.1V/5000mAh)

What reviewers say

Three verified-owner reviews of the Traxxas 3S 25C LiPo Completer Pack with EZ-Peak charger. Two reviewers rated it 5/5, describing the combo as working well, with one noting the battery charges quickly, including on the charger's balance setting. The third reviewer rated it 1/5 because the item had not arrived after more than a week, a delivery issue rather than a comment on product performance. The sample is small, so the overall picture is limited.

  • + Works well as a combo
  • + Charges quickly
  • + Balance charge mode performs well
  • − Delivery delay reported by one buyer
