About this part

Charger Note: For proper charging, the included balance lead must be used. Charging without it can result in improper cell balancing.

Redline 2.0 LiHV Battery Overview:

Gens Ace batteries have been proven within the Radio Control community to deliver reliable and consistent performance for all modelers alike. All Gens Ace batteries offer superior cell matching at the factory, and are extremely consistent in selecting matched cells after each and every batch produced. Additionally, low internal resistance (IR), offers modelers stable voltage output through the whole duration of the battery.

Features:

  • Stable automatic stacking technology
  • The most strict single cell capacity, voltage, resistance and discharge curve matching process
  • High-capacity and discharge rate
  • Low-profile and lightweight

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.

Couldn't ask for anything better. They have a great run time! They have amazing punch. 10/10

Tom DunahooVerified owneron Gens Ace Redline 2.0 4S LiHV Battery 140C (15.2V/6300mAh) w/5.0mm bullet

Good batteries that keep the punch all the way through the race. Charge up quickly and best part is they are cheaper than most others.

Steven RamosVerified owneron Gens Ace Redline 2.0 4S LiHV Battery 140C (15.2V/6300mAh) w/5.0mm bullet

Works as advertised, my only grief with this battery is the 1C max charging.

What reviewers say

Reviewers largely praise the Gens Ace Redline 2.0 4S LiHV 140C 6300mAh battery, citing strong punch, good run time, quick charging and value compared with alternatives. One reviewer notes the 1C maximum charge rate as a drawback. A single 1-star review reports a cell puffing and dropping after the first charge and run, and the reviewer questions whether this was an isolated defect or a quality-control issue. Reviews all refer to the same 15.2V/6300mAh 5.0mm bullet variant. Overall sentiment is strongly positive, though the sample is small.

  • + Strong punch and power
  • + Good run time
  • + Charges quickly
  • + Competitive price
  • − Limited to 1C max charging
  • − One report of cell puffing and failure after first use
