Praised for size, weight, and price point. However, some noted late delivery and lack of supporting documentation on the website.

Great for projects. Xain-USA website doesn't have supporting info for 7.4V

I wanted this battery for a project driving a 12V DC motor, but I didn't want a full 12V power source. This 7.4V battery was a good choice. It works as expected, driving the 12V motor to speeds faster than I actually needed, but can control with a motor controller (see photos and video). Upon receipt, the voltage of the battery measured 7.71V.The reason for a one star deduction is the Xain-USA website does not yet have supporting documentation for any 7.4V batteries (I wasn't allowed to attach a screen shot). On the battery itself, it points you to the website to "Attention: Read manual @ ...". As no paper manual or information is included with the battery, I consider this reason for a deduction. Otherwise, this is a good battery and meets my needs.

No issues here!

Worked perfectly as advertised for my cosplay project. It uses a real JST connector which I was satisfied by, and the capacity and voltage are in the advertised spec. It's gone though several load cycles at this point so I think to say that it's good to go!

7.4v. Two-wires. Fits an SM connector

I got this as the backup power for a digital scale. Fits fine where an SM connector is indicated. Works fine.

Perfect replacement for RC pack

One of my RC vehicles had a battery pack that was draining very quickly, which happens with rechargeable batteries after some time. I came across this battery pack which matched the voltage and Ah I needed at a decent price so decided to give it a try. The battery pack appears well made and the connector securely crimped onto the wires. After installing into the vehicle and charging, it works like new, as it should.
