This info if used will put an end to lfp much sooner. Never subject the cell to hit 4.2 volts.
Yes, I'm not recommending charging to 4.2V per cell. That's just what that graph used for the constant voltage phase for some reason.
A 3.65V per cell (or 14.6V for 4 cells) constant voltage phase as recommended by BattleBorn will get you you to ~95% SOC soon enough and allow cell-to-cell balancing. And just about any 1 or 2 stage charger with an AGM setting, or even an adjustable V Meanwell cc/cv power supply should be able to do that.
2Oldman had a couple of Schumacher chargers modified for his 48V LiFePO4 battery bank. Is that 16 cells in series or ?
Curious what V they get up to: 3.65x16=58.4V ?
