About this part

Gens Ace G-Tech Smart 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.

  • Automatic identification and recording of all battery parameters
  • Adjusting charging parameters to improve safety
  • Balance plug with built-in chip and exclusive patented design technology
  • Protects and extend the battery life

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.

To previous comment, you can select no signature required during checkout out. So it’s your mistake for not going over the details with your order. Besides this should be product review and not about service that’s Amain’s fault because you did not select signature not required during checkout.

Would not recommend purchasing batteries on here it required a signature upon delivery but nobody is home during the day cause we all work so then I have to go to the post office to pick it up one problem though they are closed before I get to work and when I leave meaning I had to wait a week later and pick it up Saturday I could have just ordered the same battery through my hobby shop and picked it up there after work and give my local hobby shop more business. Amazon has no problem shipping lipos and those are sketchy Chinese ones I had two batteries delivered same size on the same day from Amazon when they tried to deliver it

Best premium batteries you can get with it. These will make your cars run better and cooler. Good size didn't have fitment issues

Great battery, fits in the XRT with a small foam spacer. Excellent.

pascal Burelleon Gens Ace G-Tech 4S Bashing Series Hardcase LiPo Battery 120C (14.8V/6800mAh)

Very disappointed in the quality of these, puffed After two runs, a few cell dead after five runs I do not recommend they changed one under warranty and wont change the other one.

What reviewers say

Reviews are mixed. Several reviewers praise the battery's size and fit, with one noting it fits an XRT with a small foam spacer, and one reports better, cooler running. Another reviewer had not yet used it. Two reviewers report quality problems: one says a battery puffed after two runs and cells died after five, with a warranty replacement for one pack and refusal for the other. A separate review concerns delivery, where a signature was required and the buyer could not receive it at home; another reviewer notes the seller's checkout option to skip signature. Delivery complaints relate to the seller rather than the battery itself. Sample size is small.

  • + Good size
  • + Fits XRT with small foam spacer
  • + Runs cooler and better, per one reviewer
  • + Fast delivery
  • − Battery puffed after two runs
  • − Cells failed after five runs
  • − Warranty replacement only for one pack
  • − Signature required on delivery
