Not that I know of ,though any of those should be fine I would think. Again. Don't overestimate my knowledge. There are plenty of folks here better qualified than I am.In my single cell, mtl set ups (no ultra amps required), I use vtc6, lghg2, and sammy 30q, because they are all 3000 mah. Does the job, but do they make a true 20 amp more than 3000 mah 18650?
