I've tinkered with electronics and components for quite some time now, but I'm kind of a noob when it comes to taking things to "production".
I've this project using an ESP12-E, powered by 2 (or 3) Li-ion cells (3.3 V 18650s) through a TP4506 charging module.
I'm now building a custom PCB for the whole think and my question is, for production purposes, what's the best way to add the batteries?
- Leave the +/- pins in the PCB and solder the cells there directly (and between them)?
- Leave the +/- pins in the PCB and solder a cell holder to them?
- Solder the cell holder directly into the PCB and then just insert the cells?
- Another option :)
I'm asking also about "best practices" for mass assembly (Ideally these will be assembled in China)
