Second version allows building of a beamed power that will recharge bots (construction, logistic, military). However, it can only target X number of bots at a time. So in an area you have lots of logistics bots, if you want them to keep moving around and not having to go back to the Roboport to recharge, you'll need several of them at once. And maybe make a specialized beamed power which can recharge the character directly (when in range) which would, effectively, give the character a giant battery in a limited area. Super-fast shield recharge always in that area
