I've got over 600 miles my on my Mantis King GT it's been friggin great so far. Excellent suspension, Brakes can't be better. Unfortunately my battery died and I thought it was the fault of the battery itself. But I learned that I've been charging using both ports. You can't do this, this is designed for seldom quick charges. You need to charge by single port ONLY otherwise you will damage the cells which I have done. I've ordered a new battery. Unfortunately they sent me the wrong one for the Mantis not the Mantis King GT.
But I have to say (Juan) they were very quick to admit and apologize for the mistake.They sent me a return label and an expedited new battery which I'm very grateful for. So far the Mantis King GT has been awesome and so is the support. Thank you Voro Motors.
