Last time I did it in well into Float with an external charger. Got a "vibe" that my timing was off.

Isn't it best to Equalize some time in Absorb? Photowit does this procedure every month - hope he is around.

    IMO, when to equalize is best determined by measuring how unequal it is.

    I am available for custom hardware/firmware development

    Would suggest EQing FLA batteries  at the very end of Absorb,  or just after Float begins,   as recommended by a number of FLA manufacturers.
