Zeee (9000mAh) - 11.1V 100C 9000mAh 3S RC Lipo Battery Deans Connector with Metal Plates for RC Car Truck RC Models Traxxas X-Maxx and Arrma Infraction

So far this battery is great. It arrives perfectly balanced and charged right up. The battery is HUGE make sure you measure. I'm running this in a 2wd slash vxl and I did have to make a slight modification to the battery tray for the wires to fit. Also if running a slash you'll need part TRA5827X from traxxas which is for taller batteries. This is my first battery ever so I don't have other to compare it to but it does seem to run forever. I've watched YouTube videos of people only getting 15-20 minutes on Traxxas batteries. This battery last much much longer than that, I'm thinking close to an hour of pretty hard bashing.(No actual time test). This is a soft case battery that does have reinforced sides. The 8000maH version is a hard case and will probably fit without modification as the wires come out of the top.

I believe it's mAh rating is true. Last 3x as long as my 3000mah . Math serves itself there. Id buy again. Also it's way bigger than the picture seems. Not small at all. If fitting on 1)10 scale you will need modification

Powerful, consistent run times, takes a high amp charge well...all in all I'm quite happy for the money. 10 out of 10, would buy again

Best bang for Your buck. Priced reasonably and good quality.

Pretty good value but at less than 20c discharge rate, the 12 gage output leads get pretty hot. I'm changing mine to 10 gage wire. Hopefully that will reduce heat buildup produce more power.
