How to Make a Battery Adapter for Makita 12V BL1013

How to make a battery adapter for Makita 12V BL1013

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

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.

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.

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!
