Great for high powered tools.
This battery is amazing. It feels like it lasts forever and is my go to battery for my higher powered tools like the grinder and circular saw. It is heavy and bulky but it's worth it for the high power tools compared to swapping the smaller ones nonstop.

Batteries still leaking
Just recently ordered a battery and it looks like a fresh item straight from Flex but it showed up leaking in the package - Will update review once I hear from Flex but this was supposedly fixed from their Gen1 series - not a good look when these batteries cost more than the competition **EDIT** - Flex fully took care of this and sent a replacement battery quite rapidly - no frustrations - just expect you might get old stock and have to do the same, as such I am changing this to a 4 out of 5 due to their fantastic customer service
