It's been a little while since I've had a shiny new tool battery to tear down! This one showed up in the mail for some analysis and evaluation - so analyze and evaluate it I shall!
As of the time of posting, you can get 2 for $150 (shipped) on eBay - which almost certainly beats your local hardware store by a lot. But, only if they're good.
This is a notable pack in that it's (supposedly) using 20700 format cells - the first non-18650 based tool pack I've had the opportunity to rip into.
What's inside? Is it any good? Read on to find out!
