Introduction: How to Make a Battery Adapter for Makita 12V BL1013

About: Let's make something

Among the 12V power tools I have used, It seems the Makita battery BL1013 is a very lightweight one.

I hope it can have more uses, so I made this battery adapter.

Supplies

Material

  • Cardboard
  • MDF
  • Popsicle sticks
  • Balsa wood
  • Copper
  • Acrylic
  • 12V LED

Step 1: The Shell

The shape of BL1013 is similar to a hexagon, so I designed an asymmetric hexagon to fit its shape.

The code is 32+12:

long side = 32mm.

short side = 12mm.

height = 53mm.

First, use thick cardboard to build the model.


There are three layers of shell.

The first layer is MDF. 32*53 (1), 32*42 (2)

Layer 2 is popsicle sticks. 6.5*53 (6)

Layer 3 is also MDF. 32*48 (2) , 32*53 (1)

*(n) is quantity.


The vital function firmly fixes the battery when it inserts into the shell.

I must make a suitable groove to match the latches on the battery.

The groove is inside the 3rd layer of the shell.

I have tried drilling and digging holes, and finally, I think it is the best way to cut it with a saw table, and the depth is about 1.2~1.5mm.


I used some balsa wood for the short side shell.

Step 2: Power Connector

Another vital function of the case is to connect the positive and negative poles of the battery.

Use MDF to make a suitable hexagonal board and dig two small holes.


2 pieces of copper. thickness = 0.5mm, width = 4.5mm, length = 25mm.

Reluctant to throw away the pure copper radiator, I didn't know what to do before, now I know.

Drilling and tapping M3 to lock the screws.

Bend into a Z shape.

Insert the coppers


Make a 24x24 small board to fix the copper sheet.


Use a multimeter or voltmeter to test whether there is power.


When there is no problem, stick them together.

Step 3: Painting

Black and yellow

Step 4: First Use

The simple use is to make LED light up.

12V LED connect the wires to the positive and negative poles and lock.


I make an upper cover with white acrylic.

I will have other uses in the future, so I only use double-sided tape for the time being.


It's showtime.

When the battery clicks into the shell and makes light, I feel full of accomplishment!
