I am building a portable monitor. It takes 12V 3A. I found a li ion battery that I like, AFTERTECH PACCO BATTERIA PILA 12V 4200mAh 4,2Ah RICARICABILE AL LITIO 95x60x20mm F2D3 https://amzn.eu/d/33mkhP0
It has the safety BMS but no fuel gauge so I can’t have a battery level indicator.
I looked at how to get one and found this video
Which is good for one cell but doesn’t explain how to incorporate a BMS at the same time.
I looked for a board that would do everything, charging and discharging, BMS and fuel gauge but couldn’t find anything.
Has anyone built a battery powered device with a battery level indicator and how I can wire it up? I want a fuel gauge because all online resources are saying that for LI ion the old voltage tracking methods aren’t reliable.
Any advice would be appreciated
