Quattro and battery safe mode

I am using a quattro to charge my 64v lithium battery (chevy volt 16s), and I am seeing strange behavior after a firmware update. I think the culprit is the "BatterySafe" setting which is set to on. Does anyone know which firmware introduced this setting? The manual says that with an Adaptive charge curve and BatterySafe enabled, that absorption with start at 14.4 v for a 12v battery, regardless of the Absorption voltage (63.8v in my case). I assume for my battery this will force the absorption to start at 14.4v x 4 = 57.6 v? Any help is appreciated.

Given that the algorithm is mostly for lead-acid and maybe LFP, I would override to the desired absorption/float voltage and use a fixed absorption time. Disable adaptive and batterysafe.
