Battery damage (Sacred 2: Fallen Angel)

Is there a way to tweak something in the config so that the batteries are stronger and you can use the blaster instead of the hand of the temple guard exactly as the main weapon, and not an additional one, without the feeling that you are complicating the gameplay for yourself? And then in comparison with swords and other melee weapons, the damage from shots is somehow weak.
And do not whine like "fuuu casual" and "normal damage there".
