STL file - 3D Printing Batteries for the Philips Portable DCC134, 170 and 175

Hi, thanks for the welcome.
I checked the battery compartment of the DCC130, quite large, just + and - connection. So I think that with help of the parts of a 18650 holder (the spring parts - or maybe the full case) and some electronics:

  • USB to LiPo Loader with protection → TP4056 Micro USB 5V/1A Lithium Batterie Charger Modul
  • LiPo to DCC using a StepUp Buck Converter with MT3608 chip (cheap, adjustable, Vin = 2-24V, Vout = 2 - 28V, maybe that the power is a bit weak, can’t find something about the [email protected] of the DCC130)
    plus design for 3D printer,
    I may do something. I will try. Let’s see. (next step for me ist to find the original ACDC adapter to check whether all this makes sense).
    Maybe that the circuitry was published. I found only the LiPo loader circuitry attached to the Youtube (spec’d as Vin = 5V, Vout = 5V → which is not matching the original 4.8V of the battery - or is the DCC130 tolerant there?).
    Any experience on that? Thankful for an answer… and best wishes
    Thorsten
    P.S If I don’t have success… How to get an battery chassis? (Thabk you)
