Ok i would really like an experienced professional to chime into what i am going to ask here.I think i may be over doing it but i have to clarify.
For a period of time i have been researching on lithium batteries for off grid storage and i have came across something repeatedly and that is the capability for lithium to accept very high charge rates (based on c20 /other ) and also discharge ratings e.g c5/c10 etc
Now my question
If lithium are capable of such higher charge and discharge rates as compared to lead chemistry is it possible to run larger constant loads as of those recommended for lead acid batteries? i.e no load beyond 1000w for 12v systems /no load beyond 4000w for 48v systems.
So say can i run like say 6000w loads on 48v system with out hurting the battery assuming i have the wiring and over current devices for such system?
I think you are confounding things a bit. It is not impossible to do BUT.....
For the example of 1000W @ 12V, 1000W is a level at which you begin to have to have such large wire to handle that Amperage load, that the cost of wire to safely handle (1000W/12V=) 83A +- becomes beyond most peoples ability to pay... at 24 Volts, it would drop the load to ~42A... and uses much smaller wire.

yes i understand that West ,That was not what i am trying to get at.i know i am some what vague but ws hoping someone will understand
Hey, Mahendra.
6000watts @ 48v = 125 amperes. If your bank is like my own. 16 cells of 100aH. That is only a C1 discharge rate basically. You wouldn't do much to them. If I recall, these Calbs are fine to do C10 for 10-30 seconds. 1000 amps. 48kilowatts.
All doable. Just not going to be for very long! :)
