please I need a solution in designing circuit that use two power sources??

the first source is the external source from ground, this source should feed the power board without going into thermal battery,

then we the body is unattached from the ground, the thermal battery which is internal source should feed the power board with same current and voltage which is 24v

There are ways to avoid the voltage drop in the diode but they are more complicated than this simple solution.
