Step 4: Accesories
Some accessories that you may want to consider are voltage meters to see how much charge your batteries hold. Binding posts on the outside to make hooking up solar panels and other devices that connect with alligator clips easier. A 120v to 12v adaptor so that you can just plug it into a wall outlet to charge, I did not add this in my instructable because the charger that I used can already do this without the need for any additional parts. A low voltage cutoff if you plan on drawing a lot of power, my charger provides this so again I didn’t add it.
