Will it damage the battery from over discharge?

What are those metal prongs you use to tap into the battery?

Coming soon, Milwalt or Dewaukee??? you decide

Anyone willing to make these for me to purchase? I need 200 for a project.

!! I'm guessing electric car and surplus power tool batteries equals economical transportation. But how are you going to charge all 200?

Brilliant! Thank you! :)
