I’ve been looking at these series charger modules which would allow me to charge up to 3 cells in series using an external power adapter. Pairing this with a BMS module to ensure the cells are charged equally without over or under charging any I think may be a good solution. Any thoughts on these components?
In general how reliable are these cheap electronics components? Would you still recommend using protected cells for a setup like this for extra reassurance, or do you think these BMS modules are more reliable than the small protection circuits on 18650s anyway?
This video is close to what I’m aiming to assemble, minus the voltage step up because I plan to use a 15v charger: https://www.youtube.com/watch?v=SyiUzZJHVx8
It would probably save a lot of headache to find a lower voltage driver that can run on 2-3 cells in parallel so I can use the micro USB chargers, but I haven’t been able to find one that can be controlled using a simple potentiometer. I would at least like one that allows for very simple high-medium-low selection separate from the power switch.
