Zeee14.8V 100C 7000mAh 4S RC Lipo Battery Deans Connector with Metal Plates for Traxxas X-Maxx RC Truck Tank RC Car Racing Hobby

Amazing performance, especially considering the price. I had been running my Maxx on 3S and thought it was fine but it's so much more fun on 4S. I do run the wide kit and just installed the metal drive shafts. The stock ones hadn't broken yet but the rears were definitely starting to twist.The battery fits fine and the 7000 mAh capacity provides a satisfyingly long run time. Plenty of power for the Maxx and so far it is charging and balancing just fine. This is my 3rd battery from Zeee and I'm completely satisfied at this point.

When I first got my Maxx I was using the batteries I had been using in my Outcast 4s which are Ovonic 4500mah 4s 50C lipos. I was use to getting about 20 mins in the Outcast 4s, but got about 10-12 in the Maxx before the 50% LVC Low Voltage Cutoff) would kick in. So I began searching for new batteries and found these Zeee 7000mah 100C 4s Lipos. They are a tight fit, but still perfect. And the run time is more than doubled now before the LVC kicks in. I get at least 25 minutes, close to 30 on some occasions. And not only that but they are much more powerful being 100C. Completely changed the way my Maxx drives. And the price was great too considering some 5000mah packs are $100 or more. Very happy with these new batteries. Will update later if there are any issues, or to just update how they are doing. But so far so GOOD!

Thing worked great man , put a XT90Plug ! Charged it put it in my new MAXX and it woke that thing up !!!! I only had 3S till new got here . Day I ordered it . I also got the wide kit and steel axles for it . Had a set of Badlands on hand . So never drove it stock lol

So far the batteries are working pretty good. The batteries came well-balanced and had a good storage charge. I am using them for my 13" beast class drone in a 8S configuration and they do get a little warm after a flight. I am not to confident about the 100c rating, I have two HOOVO 7000 mAh 100c and they do not get warm after a flight. Otherwise, I really like the batteries I think they are good and hopefully they last a while. If something bad happens I will update this review.

This battery is amazing, 2 of them run my X-maxx in the grass 37-40 minutes, running a max-6 ESC on 20/50 gearing with proline badland tires. Only thing that was needed was to change out the deans connectors that they came with to IC5's connectors and they were perfect, dean's are ok if you aren't drawing much current but for large vehicles just do yourself a favor and go ahead and change them to something larger. Batteries balance perfect and the mah rating looks to be right as advertised. All that for half the price of a traxxas id battery.
