Step 3: Set up the SLA
This basically involves gluing a terminal block to the top of the battery, so the drill can be disconnected if required.
First, get your terminal block. Glue it in the center-top of the battery.
Now, get some cable. hook one end to the terminals of the SLA, and the other to one side of the terminal block. Paint the ends of the terminal block if you want, so you don't get your polarity wrong.
