Hey there , quite new to the subject and had no one to ask .
I am currently building a project that will need portable chargable power supply of 12v and at least 5000 mah.
My questions are :
1.how can i connect 3x 3.7v 14500 batteries so i will be able to charge them throught some kind of port on the mobile device?
2.is there any other way ? It needs to be small enough to fit a tube 16 mm width.
