What a piece of packaged energy ... beautifully made, four in a box I bought a set of eight with the additional discount. they arrived in one large box somewhere around 35 lb not too heavy to manage. The terminal spacing is perfect when placed side by side with a 2 mm sheet of foam padding between the cells to insulate and allow for expansion when charging. I am fabricating some very rigid 1/8 inch aluminum plates to compress the cells together with threaded rods. this will be one of the most powerful battery packs I have ever constructed. All cell voltages were within 1 millivolts of each other upon receiving. Excellent quality and packaging!

Nice form factor. Good studs. Only negative is cases aren't quite square and bowed.

Had I known these had screw terminals, I would've never bought them. They strip easily and you can't torque them properly. That's the only gripe I have.
