Yes, if you connect the two batteries in series. You will then have 16 volts, but the current will stay the same as if you only had one battery connected.
That is Impossible. You can however make two 6 volt batteries into a 12 volt system by wiring the two 6 volts batteries in Series. You will then have an output voltage of 12 volts but the amperes will only be what one of the batteries have, In other words the volts will double but the amps will stay the same as if you only had 1 battery connected.
Add two 1 volt batteries in series with it.
Two 24 volt batteries in parallel will give you 24 volts. The only other way is two 12 volt batteries in series.
To get 24 volts from two 12 volt batteries, hook the positive post from one battery to the negative post of the other.
Yes, series the two batteries to produce 12 volts. Tap off of the two end terminals for the 12 volts. Tap off of the series jumper for the 6 volts of one of the batteries. The two 6 volt batteries can not be paralleled in this connection as they will short out.
No. If you connect two 12 volt batteries in series(positive to negative) to make 24 volts, you will have 100 amp hours. If you connect two 12 volt batteries in parallel(pos to pos, neg to neg) you will stay at 12 volts but have 200 amp hours
You can not. Looks like you have the two and eight backwards in the question as you can reconfigure eight 2 volt batteries to produce 12 volts. Think out of the box. Parallel two sets of two batteries in series for a total of four volts. Then add four batteries in series for an additional eight volts. You now have a total of twelve volts.
Depends on the battery size. If your boat is a 12 volt system and you wire two 12 volt batteries in series you then have 24 volts. If the batteries are 6 volt batteries you will be fine. If you have a 12 volt system on your boat and want to use two batteries then wire two 12 volt batteries in parallel. You will still have 12 volts but will have double the amperage available and this will extend the running time of the batteries.
Connect two 12 volt batteries in series and you will have 24 volts.
Paralleling four sets of 6 volt batteries will still give you 6 volts. Two 6 volt batteries in series will give you 12 volts. Parallel these series sets will give you longer endurance at 12 volts. There is no way you will ever get 48 volts out of four 6 volt batteries.
24 Volts.
Two in series, two in parallel The link below has a couple of diagrams.
