Paslode 18650 battery upgrade

*** Caution *** This battery upgrade does not have a BMS (Battery Management System) as part of the build (which could cause battery danger including fire). A BMS could easily be added with modification but was not necessary in my application. Also, this battery design is capable of 8.5v DC which is above the rating of the manufacturers Ni-MH battery of 6v nominal with a full charge voltage of 7v. It works fine in my Paslode nailer but that doesn't mean it could not cause harm to your nailer. Lastly, this battery cannot be charged in the existing charger. Without the BMS each of the 18650 cells need to be removed and charged in a separate 18650 charger. I created this project as a solution to my problem, and made it available to anyone else to use as they see fit.

I have an old Paslode nailer with batteries that would not hold a charge (even brand new off the shelf of the big box stores). I was charging the battery a few hours before I needed it, and it would be dead a few hou
