FYI: These fans make a lot of power but, most motors can not handle the same cell count that they were designed for because 10 blades draws more amps than a normal 5 or 6 bladed fan. Its best to use a watt meter to see what the your combo draws. This is the only way to know that you will not damage your motor...

Example:
If your motor was designed 6s and you pair it with CS 10 bladed fan you probably going to have to run it on 4s to keep the amp draw manageable.
