Battery Ah

There is no maximum if the battery set is unlimited.

You will have to consider the Ah ratings of your batteries. The weakest one will cause the limitations.

How high is up?

What temperature is it when it's cold?

What's north of the North Pole?

Yes, you can draw lots.

How big is the wiring? You may find that your wire becomes a fusible link at some Ah discharge rates.

Ask the battery supplier.

This question cannot be answered for numerous obvious reasons.

I have done Industrial, refinery, commercial and residential projects as an electrical design engineer.

You are really starting to scare me with the content and quality of your questions.

Additional training is required or perhaps a new line of work is in order before you kill someone.

_{Jack - I have also done Industrial, refinery, commercial and residential projects as an electrical design engineer.}

I really thought that engineering stuff required some sort of math-y kind of calculus-ating and figgering with equals-ing and more numbers and stuff.

who knew it could be simpler?

Like the PE said to his intern...go figure!

Your batteries should have an AH rating, You can draw this for one hour before exhausting the supply...Say your battery is rated at 10 ah and you have 6 batteries, that would give you 60 ah total...I wouldn't recommend draining a battery bank at max rating though...your load should be well below this for constant draw....

The whole contents of the battery can be drawn, for the AH rating indicates the capacity of the battery set.

The rate at which it can be used will be determined by the smaller of either:

• the sum of the loads, or
• the circuit protective device(s) rating(s).

It depends on what load is applied on your battery set and time duration of load.
