Insulated Battery Box
Keeping batteries under optimal temperature conditions increases their lifespan and power output. For a couple of dollars I made an insulated battery box to support the solar battery system and prevent freezing and overheating.
Parts
Battery, foam cooler, duct tape
Flip and Cut the Foam Box
Place the battery in the lid of the box and cover the battery with the bottom of the box. Take a utility knife and cut around the outside of the box around the top of the battery. I measured then drew a line around the box to get a straight edge.
Duct Tape Time
Wrap the edges with duct tape to prevent more foam from breaking apart. I also added additional cuts for the wires.
Connect and Finish
Connect the power supply for charging and juice. You are complete. You can leave the box on a piece of wood or directly on concrete without excessive drainage.
