HOOVO 7.4V 70C 6200mAh 2S Lipo Battery Hard Case with Tracxas Plug for RC Car RC Helicopter RC Truck RC Truggy Airplane Quadcopter UAV Drone FPV (2 Packs

Work great. Use them constantly as a single 2s pack for a 1/10 Slash or 4Tec. Once a month both packs will get tossed in series for 4s on a 1/10 ERevo brushless to do some mild bashing and full throttle fun.Both packs on delivery were ~40% & ~50% capacity as I recall. One pack was perfectly balanced while the other was off by a decimal point.These have been nothing but reliable with runtimes going 20+ minutes. i run them 20 minutes each pack and never got a battery below 30% (maybe I'm just not hard enough on them?)100% recommend.

Great alternative lipo batteries for traxxas stampede. Doesn’t swell up like the actual name brand traxxas ones did. Very satisfied with this brand. Would definitely buy again!

Works great on both of my Traxxas/2 wheel and four-wheel-drive

Pretty new to the hobby, I was going to return these as like with most people who have because they are not compatible with the Traxxas charger until I was shown how to actually charge it on a Traxxas charger. You need to remove the little plastic cover on the left of the main charging point and connect your balance line there, then plug in the main battery line. Then you need to hold down the “charge rate select” button and the “start/stop button at the same time. What this does is allow you to select the type of battery (lipo/nimh) and the type of charge you want (fast, balance, store) and also the charge rate select (1A,2A,3A,4A) once you have selected those you hold the start button and you should be good to go. Hope this helps.

Just as good as the name brand

I own multiple rc cars it's my hobby. Therefore I also own lots of batteries for those cars. These ones are as good as any that I've ever used and a great value for what you get

First impression is they're great batteries connection is fine pretty tight, runs long, works how it should.

When I saw the picture I thought the Rex connector would be too short but it was the proper size. High quality Excellent product
