The Camble PCB for the Powerboost should work since it has the enable pin but my board does not have the LBO pin which I think his board needs so might have to go with the bangood one then (not sure it's available anymore).

Yeah...
apparently its not available anymore....

i have both here....
I was hoping it would have been suitable with the power boost one, as that has been sitting here for nearly a year


worst case scenario...
i'm just gonna try to knock up my own (banggood)
the othermods site has a complete guide on how his safe shutdown and low battery is wired (IRF7319 & LM393)
(it might just need some slight adjusting for this)

The MintyPiBattery scripts have a folder with the icons as .png file you can edit WHILE it is not running so edit them as root or before you install the lines in the rc.local file.

Thanks
I'll give that a try....

Hi Helder. First of all Great Work!!. Second, if I want to use 18650 batteries can I connect more than 1? wont be problems on the charge ratings?. Also can I use a portable power bank in the usb input without a battery connected? will it work with a pi 3b+ with mouse, keyboard and LEDs?

most power banks use 18650 batteries in parallel with no balancing. You will be fine as long as the voltage of the batteries are the same when you connect them so that they don't rapidly discharge into each other in an attempt to balance. The charge IC doesn't see how many cells there are... only the overall voltage so it doesn't care.

My wii U and many other projects have been running of parallel 18650s with no issues. (btw many lipos are made will multiple cells in parallel... this is no different)
