So how do these off-the-shelf expansion batteries work in portable solar generators / power stations?
I mean if they connect directly to the battery of the main unit, the two batteries will most likely have a voltage difference and a large inrush current will flow from one to another.
How do the manufacturers mitigate this issue?
Do they have some sort of current limiting circuit?
Also, which battery is used first ? Or are they truly in parallel?
The reason I'm asking is mainly educational, for planning expansion batteries in my DIY solar generator builds.
