Hello, I'm taking apart a powerIT! Lithium ion battery portable power supply.
The PCB board is labeled: 94V-0 E318500 HK-500W-V30 Fubing 2015
Anyway, I can't identify many of the ciruits, but they seem to have a prefered supplier. I say this because they mostly have GZ in the part numbers.
An example would be: 358 GZ448
I think this one might be an op amp circuit.
Anyway, What company uses GZ in there part numbers? Where can I track these? Maybe the PCB board as a whole has some documentation. Where can I look for that?
