Great battery for a few months. I will update on the longevity.

4/5 because my with first order, one was defective out of the box. These two seem fine so far, but just charging now. Will update once tested.Update: just a fluke!

Perfect for my rc boat

Make sure your charger is the right one for this type of battery. These batteries charged well and had the capacity as labeled. Will see how long they last with usage.

Great power output lasted about 45 mins of bashing my slash 4x4 .

The packaging came really nice and neat. I charged them up the day they were delivered and they took a full charge without issues. On first use I got the expected runtime and performance I thought I would based on the mAh. The batteries went on for the entirety of the use until it was completely discharged. For reference on a Traxxas Raptor R I got appriximately 30 minutes of runtime on moderate use. The plugs are very snug and tight. Very satisfied with the batteries.

Compared to my other batteries with the same capacity these definitely don’t last as long.

These are great batteries. I've been using them in my traxxas bashers for a few months now and they are holding up great.
