How should I charge my 4 18650 cells

[bayjose]

Hello, I have an internal 4 cell 18650 battery pack in my portable, I was wondering the best way to unify them so that they are all charged and regulated from one charge input, and then have a cumulative battery output voltage. I was looking at this board here but I am unsure which points to charge it from. Any suggestions would be appriciated: https://www.amazon.com/15A-Lithium-...227&sr=8-18&keywords=18650+battery+pack+board

thanks,

The pictures show where to connect the batteries.

The charger would be connected to the P+ and P- on the board.

Thanks, thenI should just have my PTH08080 regulators on the B+ and B- terminals yeah?

PTH08080 regulators on the B+ and B- terminals yeah?

Nope, they also connect to P+ and P-. Only the batteries should connect to B+ and B-.

Here is a sample charge or play circuit. This is what you want to model.

This charge and play circuit is probably superior for most purposes.

I just prefer the charge or play circuit. It is really personal preference. I just like one port instead of two ports. It is just a cleaner look.
