From 9:28 - 10:00 in this video, Will explains that for systems using a custom LiFePO4 prismatic cell battery, a programmable MPPT controller is required, because you will need to set a custom upper voltage limit instead of using 14.4V which the “out of the box” lithium compatible controllers will offer.
I don’t understand why this is the case, can anyone explain please? Surely the BMS will adequately protect a battery built with 4S prismatic cells and so why would you need to program your charge controller for any top voltage other than 14.4V / 3.6V per cell?
