Welcome to the CRVL forums Lucas Mill! Tell us a little more about how you're planning on using the batteries. I noticed your other post about the battery that can be operated at -40 degrees C. It's very rare for van dwellers to be anywhere that's so cold.
To help you learn the ins and outs of these forums, this "Tips, Tricks and Rules" post lists some helpful information to get you started.
Most of our rules boil down to two simple over-riding principles: 1) What you post should provide good information (like your introductory post), and 2) Any response to someone else's post should make them feel glad they are part of this forum community.
