Battery Power Supply (18650)

thingiverse

This is my mobile power supply using 18650 batteries and a DPS5005. This is an update from my design https://www.thingiverse.com/thing:2703776 which uses AA batteries. Note that it uses 18650 protected batteries which are slightly longer than the unprotected ones. The switch selects between batteries and the external power connector. Charging is not done in the case. Just use an external charger. In that way you can have and extra set of batteries, swap them and continue the wireless operation. # Extra Components digital power supply: RD DPS5005 https://www.aliexpress.com/item/1000004290003.html magnets dia 4mm, height: 3.5mm screw: M3 x 8 mm (lens head) battery contact: RS Components 324-7303 RS Components 324-7325 banana plug: https://www.aliexpress.com/item/32871905530.html switch: https://www.aliexpress.com/item/32692444364.html power connector: https://www.aliexpress.com/item/32682440489.html # WiFi I used a ESP8266 board to control the DPS5005 via the serial port. If there is demand and I have more time, I will put the PCB design and Arduino code on github. When printing, change line 10 of the OpenSCAD to wifi=true and run the makefile.
