    These are great lithium batteries, brand new, and an excellent price. They appear to be exactly as displayed in the picture. But that’s not the best parts of this purchase. They were packed and shipped brilliantly! These people are smart and I mean really smart. They pre-charge the batteries for you and they put a little sticker around The battery button so that during shipping it doesn’t get continually pressed then drain the battery. I’d give you guys 10 stars if I could!

    Very happy with it.

    I consider this a great product. The thermister, which keeps track of battery temperature is better placed than with Dremel. It is in the middle of the batteries to get an instant response where with Dremel it is away from the batteries. I charged and tested the battery and it worked great, but then I disconnected the negative wire from the batteries and added wires to the circuit board which I brought out the bottom of the case. I turned this one battery into a battery eliminator to allow me to use my dremel on any 12 volt battery. In my case, I want to run it off a regular car battery. If others do this, I suggest putting a 10 amp diode in the external power line to prevent accidental reverse hook up which might damage the tool. If I need another Dremel style battery, I will get ...
