Just finished up with my Kobalt mini power box which uses a 24 volt Kobalt lithium battery pack that is stepped down to 12 volts. The main purpose of this battery box is to power the lights and fish finder on my kayak. Initial testing indicates that one battery should power up my needs for over a 24 hour period but having extra space available in the box allows me to carry a spare battery as well. I opted for this build to be as bare bones as possible with only the essentials which for me are a power switch and an external battery connection.
