The idea came of an off-grid storage garage box in which I use 3 of these accu's for having lights and 230Vac power outlet.
Since the accu's need to be recharged frequently, carring them around is not always safe and secure, especially if charged.
Via this way I would like to give them a proper modular design to be able to stack them and foresee them of internal electronics for voltage indication wit han extra usb 5V 3A outlet.
- mdf wood, thickness 3mm
- laser cutter for wood
- wood glue
- inkscape software on pc

Step 1: Protecting Your Battery
Measure the dimensions of the battery and calculate the box size approx 10mm wider and higher than the accu itself. make it apporx 4 cm longer for the length of the accu. in the length there will be place in the box for custom electronics.
Step 2: Making Design on Line
Fill in the measurements with the extra space for the protective foam to be wrapped around the accu.
Step 3: Protecting the Accu With Bubble Wrap
wrap the accu in bubblewrap for protecting against shocks, secure it with tape
Step 4: Putting the Box Together
use the laser cutter to cut the 3mm mdf plate en build it together with wood glue. (images to be added)
- first build the base plate with the upstanding walls, using wood glue
- let it dry for +- 1h
- place the accu and put the cables through the front plate
- add extra bubble wrap if needed to fill the empty place
- glue the top cover
Step 5: Completed Assembly
Aafter the wood glue has dried up, the accu box is ready to use.
