EcoPower "Trail" 3S LiPo 45C Battery Pack (11.1V/4100mAh)
I bought this to drop right in to the Wraith Spawn. It fits in the stock position or if you move the battery tray under the hood it fits perfect. It’s awesome for what I wanted!

EcoPower "Trail" 3S LiPo 45C Battery Pack (11.1V/4100mAh)
I bought this item 28 days ago and only used it in my brand new traxxas maxx 2.0. I have been very careful about my charging and discharging practices and still it failed on me today. I am not at all happy with this battery. After only 28 days it should still charge without having issues but unfortunately that isn't the case. It will no longer charge
