Hi All,

I've been digging through the forums here for months and the time finally came to get more involved.  I caught "the bug" about half a year ago when I found out that you could salvage 18650s and build your own batteries.  I'm a salvage nut already, but this presented something that I could manage with a limited time budget until the kids are older.  I found this forum shortly after and recently started investing in gear to begin harvesting.

My end goal is to build an EV battery for a conversion project, but going to start smaller first with ideas for some custom power tool battery builds, Powerwheels battery, and flashlight batteries to build skills while I build an inventory of 2000+mAh cells.  I've got a BT-C3100 charger and already modified it as per suggestions here with additional cooling and a PC power supply.  Following Daromer's flow chart with the added step of discharging to 3.7V for long term storage.  I have a source for cells but its more of a trickle as I'm in a small town, so I'm setting up for a marathon build.  At this point I've got about 100 cells for the big build and about 20 for the smaller ones, but I'm a patient guy, and there's lots to learn in the meantime.

There is so much great information on these forms, thank you to everyone that participates.
