The total voltage drop across the internal resistance is again given by Ohm''s law: $$ V_s = V_0/R_s $$ The net effect of this is that the total voltage you''ll see across the terminals of the battery will drop as you draw more current from the battery. At some point, the voltage will reach zero -- this is when you short the battery terminals ...

So, before you try what you mention, select the inverter that has a higher voltage than the full charge voltage of your battery. If that is 260V, then go with 260V and not a higher one. Then make sure you have a voltage regulator (PWM or MPPT) with a programable overcharge voltage cut; so when your battery reaches 250V, the charging stops.
1) For example if you have a working circuit with a 10V battery, fixed 5 Ohms resistance and a current of 2A. If you then swap that battery to 20V, would it be the new current of 4A that does the damage or that fact that the voltage is now 20V? Both values are higher than they should be so which factor will do the damage, both?

The battery voltage remains constant, the discharge current decreases, and the power output of the battery decreases. The opposite is true when the temperature rises, that is, the output power of the battery will increase, and the temperature will also affect the transmission speed of the electrolyte. ... High discharge voltage; Low self ...
Before the spark, there is no current at all, only a voltage (potential difference) between two points. Arc discharge happens when the voltage is high enough to overcome the gap, and then continues when conductors are drawn apart until the plasma dissipates. This depends on how large the gap is; you can easily draw visible sparks from a 12V power supply …

Low voltage battery systems (<60V) have to manage more current which requires thicker cabling and more copper to transfer energy back to the system; this increases cost. Efficiency is gained through high-voltage systems because the architecture can support the same amount of power with smaller cabling and less copper.
