Had an interesting conversation on another forum about charging the lifeblue batteries and their built-in SOC monitoring.
Apparently you can get them upto 100% SOC according to their interior monitor, but still not be anywhere near the "absorption" V of 14.4-14.6V. In his case, the 300Ah battery bank kept sucking up 20A even at a nominal 100% SOC and V in the mid-high 13Vs. So now he manually terminates the charge when SOC reaches 100%.
Looks like flawed BMS or flawed monitoring chip. Shouldn't draw THAT much when voltage drops to 13x.
Shouldn't be kept in Absorb, either. I remember flat V-graph in some LiFe at ~90%, - I think this is when charge should be terminated.
With a monitor he at least could watch and terminate when it reaches nominal 90%, or 100% if he wishes so.
