Instructions for Making DIY RV Battery Lock

We will provide you with step-by-step instructions for making your own battery lock below.

Step 01: Gather the Tools and Materials

To make your own battery lock, you will need a few simple materials and tools. The materials you will need include a padlock, some pieces of L-shaped angle and flat metal bar, a table circular saw, a grinder machine, a hinge, a marker, a tape measure, a welding machine, a drill, and some screws.

You may also want to collect spray paint to give your battery lock a more finished appearance.

Step 02: Cut the Metal Bars

After gathering all of your materials, you will need to start cutting the metal bars. To begin, you need to measure the circumference of the battery.

Additionally, you should mark the L-shaped angle metal bar at the same circumference. In order to cut the metal bar at the marked circumference, you will need to use a table circular saw.

You must cut four pieces of L-shaped angle metal that measure the circumference of the battery to make the base of the battery lock. Next, you will need to cut two pieces of the flat metal bar according to the height of the battery.

Cut the Metal Bars

Furthermore, you will need to cut four pieces of short flat metal bar to join the battery lock from your RV.

Finally, you should cut a single piece of flat metal according to the length of your battery. You should bend this metal piece into a U shape.

Step 03: Weld the Metal Bars

The next step is to weld the metal bars together. To do this, you will need to use the welding machine.

Start by welding the four pieces of the L-shaped angle metal together to form a base for your battery lock.

After that, weld the two pieces of flat metal bar to the side of the base. Next, weld the short pieces of flat metal bar to the bottom of the battery lock. It is also necessary to weld a short U-shaped piece of flat metal to the bottom of the battery.

Step 04: Drill the Short Metal Bars

Now, you need to drill the short metal bars in order to attach them to your RV. To do this, you will need to use the drill. Drill holes into each of the short metal bars. The holes should be big enough for the screws to fit through.

Step 05: Weld the Hinge

After drilling the holes in the short metal bars, the base of the battery lock is now complete. The next step is to weld the hinge to the top of the battery lock.

The hinge will allow you to open and close the battery lock. First, cut the hinge according to the size of the side flat metal bar.

Weld the hinge to one side of the battery lock. Then, take the flat metal bar and weld it to the other side of the hinge.

Step 06: Smooth the Edges

Now, you need to smooth the edges of your battery lock. To do this, you can use the grinder machine. Grind down all of the rough edges until they are smooth. Be sure to take your time and be careful while grinding the metal.

Step 07: Paint the Battery Lock

After finishing all of the welding’s and grinding, you can now paint the battery lock. Use good quality spray paint to cover the entire battery lock. This will give your battery lock a more polished appearance.

Step 08: Install the Battery Lock

The final step is to install the battery lock on your RV. First, make sure that the surface you are attaching it to is clean. Then, use the drill to make holes in the surface. Screw the battery lock in place using the screws that you have collected.
