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.
You do not need three 12 volt batteries to get 24 volts, all you need is two batteries. So I assume by using three batteries you want to increase the amperage. Wire two of the batteries in series and then wire the third battery to the second battery in parallel and you will have 24 bolts. Or you can just wire two 12 V batteries in series to get 24 V.
Yes, you can wire two 6 volt batteries in series to create a 12 volt output. To achieve this, connect the positive terminal of one battery to the negative terminal of the other battery. Then, you can tap into the connection point between the two batteries to create a separate 12 volt output plug while still maintaining 6 volts across each individual battery.
To get 24 volts from two 12 volt batteries, hook the positive post from one battery to the negative post of the other.
Yes, if you wire them as two pairs in series to each other. Two batteries in series will give you 24 volts, and another two in series will give you also 24 volts. put the two 24v groups in parallel and you have 24 volts.
Two 24 volt batteries in parallel will give you 24 volts. The only other way is two 12 volt batteries in series.
You hook them in parallel pos to pos and neg to neg.
Two in series, two in parallel The link below has a couple of diagrams.
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.
Wire minus - to positive +. Know that this will increase the voltage but the amps will stay the same. Wire two 12 volt batteries together in series and you have 24 volts. Click the link.
Yes, but know that when connected in series you will increase the voltage but the amps will stay the same as one battery. If you wire them in parallel you increase the amps but the voltage stays the same. Example: Connect two 12 volt batteries in series and you then have 24 volts with the same amperage as one battery. Connect two 12 volt batteries in parallel and you will have 12 volts but the amperage will double.
Connect two 12 volt batteries in series and you will have 24 volts.
