I have a 6V battery and I'm wondering if I could charge my mobile phone's 3.7V battery using it. Is it as simple a case as just connecting the + of the 6V to the - of the 3.7V and the same with the other terminals? Or would I need to use resistors?
Also, would it work if I took the charger adaptor and just connected the + and - of that to the 6V battery and then plugged it into the phone?
Or would all this just result in a massive explosion?![Frown :( :(](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
