Rustler VXL at minimum I get 45 minutes of runtime and the most I've gotten was a little over 1 hour. What I was most impressed about was the new top speed of 64mph. 
slash 4x4 with castle Sct combo I get about 17 hard track nonstop minutes. Bashing I get about 25 to 30.
2wd Slash Raptor, about 40-45 minutes of run time in my stock 2wd Slash Raptor (Titan 12T xl-5 system).
4wd sort course truck at the track nonstop. Most will get 30 minutes out of this battery for typical use. And this battery outperforms the 5000mah Venom in both punch and duration.
ECX Torments ran for 35 mons and it was strong the whole time.
Axial SCX 10 Like 3 plus hours.
Traxxas Bigfoot
Redcat Blackout Pro Get 35+ minutes with lots of high-speed bashing.

HPI bullet st flux, they perform awesome in my hpi bullet st flux. Lots of power and decent run time.
Losi SCTE 2.0, Super low internal resistance and matched perfectly.

They fit my Stampedes and last a good while. Maybe 45 minutes to an hour.

    for about 40-45 minutes of run time in my stock 2wd Slash Raptor

    Posted by Timmy on Aug 20th 2018

    I purchased two of these and put them to use a few days later because I had to wait for the Deans to Traxxas conversion cables... The battery provides a surprising punch and consistent power for about 40-45 minutes of run time in my stock 2wd Slash Raptor (Titan 12T xl-5 system).

    awsome product at an unbelievable price

    Posted by Fabian on Nov 13th 2017

    i recently picked up a pair of these, and i was amazed at how great they were for the price. i have used them in 2 vehicles so far one brushed (crawler) and one brushless older FTTC4. and the power and runtime i got from both was amazing. i was outside with my crawler and next thing i know the room mate is coming out yelling stating i had been outside over an hour ??????? and and i only took one pack outside with me LOL. then onto my FTTC4, i took it down to the local smooth parking lot to run a bit and with my setup which i setup up more conservative when the kit was discontinued by associated and i managed a good 30 to 45 minutes out of a pack. really do yourselves a favor buy one of these packs you wont regret it, has the will and the way to put a smile on your face, it did mine :D

    Perfect for Upgrading Slash 4x4

    Posted by Kyle Smith on Aug 8th 2017

    I just got this battery to use in my traxxass slash 4x4. I was replacing the NIHM that came with it. The NIHM battery only lasted about 12 minutes at full speed on my 4x4. Now with the new battery I am able to get over 25 minutes of run time on the car!! Not to mention charge the battery in 2 hours compared to 8 entire hours for the NIHM Battery (Geez who has time to wait for this thing to charge?). Overall it is a much better experience driving my car around in the mud! The battery mechanically fits perfectly in the slash with no modifications! Overall I am pretty impressed with the build quality of the battery. It is pretty nifty that the cables are not permanently attached. I wish however the seller sold it with different connector options like XT-60. So I did have to replace the deans connector with an XT60. The only thing I am concerned about is the charge leads becoming loose over time. I will update my review if this happens. The battery seemed to have shipped in a fully charged state instead of storage charge which is cool because you can use it right away. I did fully charge then discharge it on my accucell 6 charger and the 5000mAh was in the range of error on the accucell charger. So they do not lie about the capacity on this product. As for charge cycles I am only at 5 cycles and no depletion in capacity. Buy now think later! This will upgrade your slash beyond belief. Make sure you change the program on your Speed Controller before using a lipo!

    Great work Gens Ace on a amazing product

    Posted by KYLE on Oct 25th 2016

    I have used many lipo batteries in the past, but I have to say these are by far the best I have used for my 2s applications. Quality is top notch and they have way more punch than the other brands I have used. Have tested other batteries of equal ratings and the Gens Ace brand out lasts and out performs them all... Great work Gens Ace on a amazing product. 50 cycles in on my last order of these packs and still no puff or sign of decreased power!!!
