    I ordered this open box battery with a different connector. It was shipped out quickly and arrived quickly. The battery looked new, no indication of previous use. The XT60 connector was installed properly and looked correct. A check on the battery showed a good storage charge and the cells were balanced. I charged the battery and tried it out.

    The battery performed perfectly. It was a great price, and I received fast, great service from the Dirt Cheap RC.

    I have purchased here before and will continue to. They are a reliable vendor and products are as described. The prices are great too!

    This is a great replacement battery for stock Blade QX3 quad. It’s lighter, shorter, and more powerful than stock. There is no way to beat it. It also has been durable in the last six months that I have used another one.
