This is a great set of replacement lipo batteries for your RC car. they work really good. Hold a decent charge and provide a good fifteen to twenty minutes per battery of play time.

Not a good motor. It didn’t have enough power and didn’t work properly.

I tried using the supplied battery pack with 4 rechargeable AA batteries but it wasn’t enough voltage for a 1:10 scale servo. The servo would intermittently work. But I knew the servo was good.I then connected a 2s 7.4v LiPo with the same red JST end. It worked great. Centered my servo and did a sweep test perfectly.
