Is it possible to connect 2 batteries and use as one?

I've got two original Samsung note 5 batts. They currently have 2300maH and 2800mah capacity left.
I searched online for this, I only found here in xda a threat, someone said that if batts are same model and parameters connecting them might work....
Please comment

Probably not a good idea. If one shorts internally it may get fed by the other. Double trouble.
May screw up the power controller ability to effectively monitor charging and lead to a Li failure.

Right...thanks for this

You should probably pass on that....

You can try it. I'm not real keen on the Frankenphone thing. Using frequent midrange power cycling (40-80%) may be a better plan.

what will happen if I connect battery for another model of samsung, something like 5000maH? (assuming, the batt. has same voltages..and parameters)

It will probably charge normally as I believe the charging is voltage based. Whether the battery thermal sensor will work correctly is another concern. That is important as it helps set charging rate and the under/over temperature behavior of the controller. It may take longer to fast charge as the power controller circuit may not be able to sink that much current.

ok, thanka for the information.I could go deeper to check if a script could make custom-management of th. sensor ,based on diff. parameters of battery, but I even if it can, there would be other problems i guess; lost cause

You're welcome.
People do create Frankenphones using huge batteries but they are awkward and more likely to be damaged in a drop. As glaxys graphically illustrated it's a crap shoot if it will go supernova on you. An optimized Samsung will generally get good SOT with the stock battery.
