When I fully charge my battery, the budget 2amp/54.6v rated charger cuts off at 54.0v and then will cycle on and off briefly for a while... is this typical? I realize that 0.6v on a 13S battery pack comes to 100ths of a volt per cell so its not that I think it is a problem. Especially since my plan is to charge to 80% most of the time anyway.

There is an electron (charged particles) exchange going on between a piece of lithium and a piece of nickel inside the battery. If one side becomes completely depleted of charged particles the element itself begins to lose electrons decaying the element and releasing gasses, this is what you see if you''ve ever seen a battery swell up.
