4S Lipo Battery 9000mAh 14.8V 100C Soft Case RC Battery EC5 Connector with Metal Plates for RC Car Truck Tank Racing Models (2 Pack)

So far these batteries have been mint. Tons of run time out of them and they fit like a glove on a stock XRT chassis as long as you do your part in routing the cables. I've ran the truck 4 times for 15-20min each time and never recharged. Once they went on the charger they were only at half charge. I'll be buying more of these!

Best Batteries that I have had yet!

Bought for the aRRma Mojave 4s. These things are awesome though they are much bigger and required some mod to the car. Very happy with their performance!

Great set of batteries for my rigs. They do seem to drain quicker than my others, but for the price savings, its tolerable.

If you want a set of lipos that drop right into your XMAXX these are the ones to get. These lipos have great power delivery and plenty of punch. Run time is excellent, I am usually done with my bashing before these lipos are dead. I wouldn't hesitate on ordering more to have as spares.

One battery charges out. The other battery on charger for three hours and no complete charge.

Brand about five cycles through these batteries in my 32 inch impulse speedboat, got to be running close to 70 mph with these batteries and everything is stuck. So far so good I think I’m going to order another set, no matter what battery you get you can control the lifetime by charging your batteries in storage mode when you know you are not using them for more than a day or two. Happy with these batteries so far

one battery is great, the other one failed with only a couple charges. hit or miss on these. the good one still punches hard and lasts a while.
