After gathering this much charge on his batteries, he immediately piloted the drones to come back to him. Although things had gone well these past few minutes, it didn't mean that they weren't going to notice it in the future.
It was best to gather all of his charges first before he continued on.
He took out his own battery and attached it to his chest, which would now serve as his personal bank for Aubility Power.
Once the drones were right in front of him, he took out the batteries underneath their frame and attached it to the battery on his chest.
As soon as they clicked together, the Aubility Power stored in those batteries started to transfer over to his battery. It wasn't long before the two were drained back to zero, while the battery on his chest surpassed half of its peak charge.
He now had 67% battery charge ready to use whenever! This was enough for him to get two 'Quantum Steps' without having to dip into his own Aubility Power.
