[RE-wrenches] Midnite Powerflo16 to old OB inverters

[Bill Battagin]

Midnite just changed their absorb voltage to 56.4V.  For what its worth, 
I treat the batteries from manufacturers exactly the way they say, I 
don't want to do anything that may jeopardize the warranty.  Also with 
LFP batteries, its not just a pile of cells, no doubt each manufacturer 
has their own tweaks to their proprietary BMS, some have heat, some 
don't, all absorb set points are not the same, etc.
