<DocScrutinizer05> 16.8/4 = 4.2
<DocScrutinizer05> highly unlikely
<DocScrutinizer05> I think I elaborated on that several times
<DocScrutinizer05> even under moderate load cell voltage rapidly drops from 4.2V to 4.0V or less
<DocScrutinizer05> 4*4.0 = 16
<DocScrutinizer05> this is a CAR amplifier, it's supposed to survive all sorts of really nasty abuse
<DocScrutinizer05> car power supply is only one thing guaranteed: it's dirty like hell, and you can have voltage spike up to 50V and more
<DocScrutinizer05> "10.8V to 15.1V" is the "recommeded operating conditions", _not_ the ABS MAX ratings
<DocScrutinizer05> bottom line: simply ignore that non-issue
<DocScrutinizer05> rather worry if your battery pack is supposed to survive a 100A load
<DocScrutinizer05> 14.4V seems to be the NOMINAL voltage in a 12V car system
<DocScrutinizer05> so heck yes, it will survive a 16.8V

<arossdotme> DocScrutinizer05, yes ive asked about it before, and took note that 4.2 freshly charged voltage for a cell isnt the reality when theres a load. so i tried my smaller car amp which says its has a max of 16V or as ya put it a "recommend operating voltage" and i found it droped to hmm something like 15.8v. so i was still (perhaps not so logically,) worried with this new car amp that said a slight lower volt. anyway thanks for your reass
<arossdotme> urance. ever appreciated!
<arossdotme> i head over people can connected there car amp to 24v systems and damgaed them/not working anything i think. so i wasnt trusting of there being margin. but 24v is a lot more that 16v :)
<arossdotme> the manauals give the speaker watts ratings at a reference of 14.4V. so lead acid batts are not ideal cus one cant max the amp out
<arossdotme> thanks muchly for the help and context, puts things into perspective when you say spikes upto 50v :)!
<arossdotme> now to get it and try it out :)
<arossdotme> oh dam before i can run it off batt i need to get a higher current rated/limited BMS
<arossdotme> only got a 20A one, that was scary enough! but now its doesnt seam so much...
