Capacity and changing speed are two different things. I know from lipo cells used in Rx models that discharge speed is given in C which is derived from the max charge current per cell IRK. This Indicates that you can charge a battery with two cells faster. Given a good battery management system of course.

Real talk: are you in dialup or something like satellite with really bad rates? Backwoods? Fire watch tower?

Excuse be but are you from the past?
