The Ion Battery was a static defense weapon developed, manufactured and sold by the Wandrau Arms Corporation. This common, free-floating solar-powered ion cannon weapon platform was an extremely effective defensive weapon. When placed in strategic positions around a space station or other vulnerable target, the Ion Battery was able to provide independent firepower that significantly increased the target's protection. The solar arrays on either side of the cannons provided all the power the weapons needed, so long as the Ion Battery was located a suitable distance from a primary star.
