3D model description

Here you will find the housing to make your printed portable Power bank for phone which uses two 18650 lithium ion batteries.

  • The 18650 Lithium ion cell is Samsung SDI ICR18650-26F (the cells are collected from laptop battery - HP)
  • The electronic was used this: Micro USB 5V Lithium Li-ion 18650 Battery Charger Module Phone Charge Power Bank (Ebay) Module t6845-c

For now I print the housing in PLA, but you can also print it in PETG.

You will get: Top and bottom housing, extra bottom housing with hole (for clip), the clip, top and bottom cell (18650) holder with different hole dimensions.
Please note that the negative side of the 18650 cells go to the short cell holder and the positive side of the cells go to the large cell holder.

⚠⚠⚠ Two cells are connectrd together in parallel. For making the connection use spot welder with nickel strips. You can also make with soldering (like I do for that project) but then make sure that you will solder fast that you will not overheat the cell ⚠⚠⚠
