ALTERNATOR specs

I am studying an upgraded battery setup using Lithium batts which allow much more current storage in the same weight and dimension ..

letting aside just for now the $$ issue ..
another limit could be our alternator's ability and compatibility at charging the increased capacity, would need to know more about specifications of our stock alternator
- brand / part number
- charging current: The peak charging current and normal constant charging current at different rpms ....

not for sure: this is what I m looking into ..
in any case, when I'll have the above looked after values, it will be no problem to make a suitable control system.


Low temperature point - if exceeded, replacement required
.. never happened to me to let my car at below -4 F !

Low voltage point - if exceeded, replacement required
actually the 10Volts lower point cannot ever be reached as our stock management system stops everything at near 11 V

.. you should know we are talking about something different from Li-Ion !Expensive!

ciao !

but also in old style with cobalt (like in you tube video) , hazards could be avoided simply putting a temp sensor cut-off
