The customer contacted us to repair his old Parkside PAP18-1.5 A1 battery. Battery capacity was low and customer wanted to bring new life to battery.
For replace we chosen VTC4 cells from Sony/Murata, they replaced old low quality parkside cells.

For connections between cells we used few pcs 0.2mm pure nickel strip.
