#fedihelp:
Does someone have experience with charging #Einhell and #Ozito 18V batteries (#PowerXChange, #PXC)?
I wanted to charge them with this kind of charger module, marketed as #PD45W: https://www.ebay.co.uk/itm/365962537770

Unfortunately, it doesn't work. While the SOC indication seems correct, neither charging nor discharging works and I wonder why. Discharging with an #SW3518 module works without problems.

I can even charge my notebook with the power tool batteries now 😎 and also my @pine64 #pinecil works via the #SW3518.

Now I just need to find out how to charge the batteries without the clumsy #Einhell chargers... 🤔

Still not there, but at least I learned that there seems to be a MOSFET in the #Einhell batteries that controls charging it.

Now the question is: How can I enable charging? So how do charger and battery communicate? 🤔
