thingiverse
Parts needed for this: 2x 18650 cell 1x TP4065 lithium charging module 1x MT3608 DC-DC step-up module some flexible and solid copper wire I needed a 18650 battery holder for my R/C Boat. This compartment also includes a TP4065 lithium charging module and a MT3608 DC-DC step-up converter. The output voltage can be adjusted from battery power up to 28V/DC. There is a small hole on the side of the model, where the potentiometer can be accessed. There are also some holes, to see the LEDs during charging. A M3 screw will self-thread itself in the corresponding hole. I charged both cells completely, before connecting them in parallel. I will not take any response when cells catch fire, nor any other damages due to this build.
