If i were you, i would try to source a connector and 3d print something to make the cells pluggable.

Wish they were in 4S format.


They communicate over I2C (if they are similar to laptop packs).

The chip that manages them was made by Texas Instruments (last time I had a look) and was able to pump out all kinds of usefull data like Wh remaining.

An arduino project would be an interesting endeavor.



OR you could say enough with high tech cr*p!

In that case, I would form the cells as parallel chains that are balanced capacity wise. (There was a website for that that jhurgia recommended).

Find a good connector that connects the strings in series. This connector would also double as your charging port. So depending on what you connect to this connector you can get 4S output or all cells parallel output. Then you can have single power supply charging without the need for balancing.

I Hope I was able to make myself clear.
