He did it in ROT to Drexl riders:
"Bane didn't take the time to revel in the fear of his fallen enemies. Before they even hit the ground he'd turned his attention to the third opponent, unleashing a storm of Sith lightning that reduced the riders to ash and the drexl into a hunk of charred and smoking flesh that dropped from the sky."
If thats not enough, from DoE:
"He didn't stay down, however. He sprang back to his feet, simultaneously drawing his lightsaber with his right hand as he sent a blast of lightning out from the fingertips of his left. The violet bolts should have incinerated all four of his targets on the balcony, yet again the strange power interfering with his ability to draw upon the Force hindered his efforts."

"As she gathered herself to charge, Bane fired off another bolt of lightning. She ducked to the side and it whizzed past her ear, striking the wall and sending up a shower of dust and stone flecks.
Despite missing her the first time, Bane followed it up with another blast on the exact same trajectory. Turning her head to follow the course of the misguided bolt, Zannah saw where the first had hit the wall. The stone had been disintegrated in a fist-sized hole, revealing something that looked like bright red plastic beneath it."
Drexl riders are people.
