If you are referring to the main battery cable use 00 guage cable.
can 6 ,12 volt battery be wire to make in to one 24 volt battery for solar use in home
Use 8 gauge wire.
4 gauge wire.
Place a current meter (rated for several hundred amps) in series with the battery. Or Place a large gauge wire of known resistance in series with your battery, use a high precision volt meter to measure the voltage drop across this piece of wire, then divide the measured voltage drop by the resistance of the wire. This will give you the current traveling through it.
No
No, it will overcharge the 6 volt battery.
No it will not work
No, the battery will be overcharged and battery damage will occur if it is done.
No
No.
To use two 12 volt batteries in a 24 volt system they must be wired in series. For this explanation I will refer to them as battery #1 and battery #2. This answer describes the wire connections for a vehicle with a negative ground electrical system. The cable from battery#1 Negative terminal connects to ground (Frame or engine block). The cable from battery#1 Positive terminal connects to Battery #2 Negative terminal. The cable from battery#2 Positive terminal connects to Starter solenoid.
