Battery Question

[Mawile]

Hi,
What voltage would I charge these at?

Also would this PCB protection board work for the above batteries? Can I input a slightly higher current than 300ma to charge these batteries?

They have a pcb already inside each one.

Each one has to be charged at 3.7v.

I have no idea if you could wire these together at 7.4v and use a 7.4v pcb and charger with the pcb's inside them. I wouldn't do it.

There are other 3000 mAh lithium ions without pcb's out there.

do you know if these batteries have a built in PCB?

EDIT: never mind messaged seller.

Most of the 18650's off ebay are rubbish.

If you need only 7.4v and it's for a portable, I would definitely suggest different batteries...

An example of the type

but being from ebay, might be rubbish too
