Frankly, rubberlele, how experienced are you in electronics?
Something makes me think that you are not very.
It may even happen that you make some fault that is so basic that we never think of.
For example, what do you mean by "what voltage and current will come out" (referring to your starting post on this topic).
The battery is a voltage generator, so you should not measure directly what current will come out of it. Measuring current is quivalent to short circuit. I can tell you: WAY TOO MUCH current will come out, if you just connect an amp meter directly across the output. If you are lucky it will just blow the fuse in your multimeter. The amp meter should always be connected in series with the load, and it must never be connected across a voltage generator (like batteries, power supplies, etc.).
The same thing: have you ever tried to measure what current will come out of the wall sockets in your home? Do not try it for Gods sake!!!
So when you measure the voltage on the output of a battery (or the wall socket), no problem.
But the current depends on the load resistance I=U/R. If the output is short circuited either by wire or by an amp meter or any low resistance it can produce so high current which can even blow up the battery in some time because of overheating.
I think some learning and some smaller projects could come first before making the bigger shots like this one.
