- Carefully disassemble the battery
- Separate the battery pack and assemble a new one with only 3 cells in parallel
- Solder two cables to the charging module in the same way as seen in the photo (you can leave them longer and cut them later)
- Solder the cables from the board to the battery packs so that they are on the side and on top
- Then place inside the case and place the lid (preferably glued)
- Put your new power bank to charge! and it's ready to use
