Bought a Mojave 4s and this battery. AMain Hobbies was quick delivering my toys! And Easy to track. Will be buying an RC for my wife soon. But this Gens Ace 8000mah 100c battery rips! In the Mojave, get about 30mins of hard runtime.

I’m new to the RC world and I haven’t tried any other lipos, so I can’t make a comparison. Works great in my Outcast 8s EXB. Was able to go about 40 minutes using 2 of these and they never became hot.

Bought 3 of these. One swelled up. Other two work as they should. Good run times

Brian ShaferVerified owneron Gens Ace G-Tech Smart 4S LiPo Battery 100C (14.8V/8000mAh) w/EC5 Connector

Had a dead cell and another battery not charging, Amain hobbies customer support is truly one of a kind. They got my batteries warrantied and shipped me out a replacement set the next day after contacting them. They really are the best company to deal with Richard from customer support always helps me out and gets things done quick with a great attitude. I will always shop from you guys for this reason. These batteries are great and last a long time on my Kraton 8s.

Eric JohnsonVerified owneron Gens Ace G-Tech Smart 4S LiPo Battery 100C (14.8V/8000mAh) w/EC5 Connector

Very good batteries. Truck broke before batteries ran out, that seems to be happening no matter what batteries I use. They had a lot of power. Need to adjust battery tray to fit, but fit perfect in Kraton 8s once the battery tray was adjusted. I just wish I could find an rc truck that will run a few times without breaking. Starting to think it’s the cold weather, the last 2 rc trucks seemed really brittle, Losi super Lasernut was just appalling, like glass, total junk. Kraton seemed better built but plastic swing arm shattered into 6 or 7 pieces after 3 feet of air. 40 degrees both times, maybe these are only good in warm weather, completely stumped at this point.

What reviewers say

Reviewers largely praise the Gens Ace G-Tech Smart 4S 8000mAh 100C pack, citing strong power, good run times (roughly 30 to 40 minutes reported in some setups), and cool operation, with fast charging also mentioned. One reviewer reported a swollen pack out of three purchased, and another reported a dead cell and a non-charging pack that were warrantied. Several reviews praise the retailer's fast shipping and customer support. One reviewer noted the pack needed a battery tray adjustment to fit a Kraton 8S. A single one-star review criticises delivery, where a package was left without the recipient's signature. Several reviews also mention vehicle breakage, which reviewers attribute to the vehicles rather than the battery.

  • + Strong power output
  • + Long run times
  • + Stays cool under use
  • + Fast, responsive retailer support
  • − Occasional swollen or dead cell
  • − Needed battery tray adjustment for a Kraton 8S
  • − Delivery complaint (unsigned drop-off)
