 what happen to one battery(12v) that is charged by two batteries(24v)?does it show 12v or 24v when you measured it by a multimeter? it does not make a sense if it is 12v?(but you might right,just wondering.)

He  IS  right.
One of the batteries might explode, if the wires or terminals didn't melt off first.

You need to read and understand some of this stuff before someone gets hurt.  
Or worse.

Start with Ohm's Law. Then Watt's Law. Then Kirchoff's Law.

If this is some kind of a joke, it is not funny.

G-;

I think a lot of folks do not "get" the kind of instantaneous, violence a large [or even small] battery bank can deliver faster than you can even register anything happened.

In my misspent youth I was working on a forklift battery and accidentally shorted the bus bars and had the dubious honor of seeing lead terminals melt and flow away from the connections at light speed amid a thunderstorm of sparks and crackling noise. All took  like a half a microsecond. Luckily I was wearing long sleeves a hat and sunglasses and no battery exploded just the sparks smoke and molten lead spewing around.

Oh, yeah the wrench was pretty much fused to the bus bars. Needless to say it destroyed the battery by melting or mostly melting off the terminals on all of them. Was not my finest moment but I learned to respect batteries from it.

Just something to think about before diving into the handling of batteries.

You Mileage May Vary.
