Hook then up in Series. Positive to negative. You then have 24 volts but the same amperage of one individual battery.that will short out other battery
Separate the 2 12 volt batteries and charge them individually.
You would need to connect the two 12 volt batteries in series. That will give you 24 volts and the amps of one of the batteries. Voltage doubles and amps stay the same.
To get 24 volts from two 12 volt batteries, hook the positive post from one battery to the negative post of the other.
No Yes. hook two in series, two in parallel.
NO. Absolutely not, you must hook them in parallel. Two 12 volt batteries hooked in series will give you 24 volts with the same A/H of one of the batteries. Hook them in parallel and you will still have 12 volts and double the A/H of one of the batteries.
in series
you only need two 12 volt batteries to make 24 volt. connect them in series
use two 12 volt batteries in series.
Two 24 volt batteries in parallel will give you 24 volts. The only other way is two 12 volt batteries in series.
Hook a 12 volt light to a 24 volt system and the light will burn out in seconds. You need a step-down voltage converter to do this.
If you connect them in series the Voltage will double but the Amp Hour Capacity stays the same. Click the link.
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.
