    1/5 went bad.

    Posted by Billy Evans on Apr 10th 2020

    I purchased 5 total. Some from amazon. But these week started using one of them and started swelling a little. My first gen ace battery to swell. Not sure if I want to try another one or not.

    Gens Ace batteries

    Posted by Deffino on Aug 20th 2018

    My kid gets about a half hour with his Stampede 4x4 with these batteries, they have great punch and always take 5000+ mah charge. You will not be disappointed with Gens Ace batteries. Hope they stay in stock.

    My new go to batteries!

    Posted by Welsh on Aug 15th 2018

    My new go to batteries! I'm running 2 for 4S and they have KICK and range! Way more than my Turnigy lipos! Packaging was professional, batteries appear to be of a high quality. Wish they made cheaper 3s versions at this price point. Not only are they in a hard case but they have a protective clear shrink wrap around them. The cells are consistent after probably 20 charges and going. Running in an Arrma Kraton 1/8th scale with stock set up.

    Excellent Batteries for an Incredible Price

    Posted by Andrew on Apr 7th 2016

    I purchased 4 of these batteries for my Slash that I use for bashing. My run time extended from 10-15 minutes on the factory NIMH batteries to 25+ minutes, and it's consistently fast throughout that run time. I will continually purchase these batteries as needed, the value and performance can not be beat.
