In any electrical system
, the sum of the currents flowing into a given point must be equal to the sum of the currents flowing out of that point. Part of Norton's theorem I believe.
So, in the given situation, simplified, let's say we have current
being demanded by the load (let's call it L), and we have the current
supplied by a generator
(G). The current (B) going to the battery
bank will be G - L, so if G and L are about equal, there will be little current going to or coming from the battery
. So, no stress to the battery.
