Wire two of the 12 volt batteries in series and the third battery in parallel with the other two. As the two batteries wired in series will give you 24 volts but the amps of only one of the batteries, unless you need the extra amperage of that third battery I would just go with two batteries wired in series. But if you want to use three batteries then connect the positive from one battery to the negative of the other battery. This will give you 24 volts. Now just connect the negative of the third battery to the negative of the first battery connected in series with the second battery. Now connect the positive to the second battery to the positive of the third battery. You will now still have 24 volts but twice the amperage of one of the batteries.
Connect three 12 volt batteries in series. You will triple the amperage but the volts will remain at 12. Click the link
wire it in series
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.
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.
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.
You can only do that with a transformer. Or you can wire three 9 volt batteries in series to get 27 volts.
To get 24 volts from two 12 volt batteries, hook the positive post from one battery to the negative post of the other.
Take 3 twelve volt batteries Run the + of battery #1 to the - of battery #2. Run the + of battery #2 to the - of battery #3. Use the + of battery #3 for your positive feed, and the - of battery #1 for your ground.
If you have two 6 volt batteries you can take a jumper wire and connect the negative post on one battery to the positive post on the other battery then connect the remaining pos and neg posts to the 12 volt battery charger.
You hook them in parallel pos to pos and neg to neg.
Connect the two batteries for the voltage needed. If they are 12 volt batteries and the lights are 12 volts, connect the batteries in parallel (negative to negative and positive to positive). If they are 12 volt batteries and the lights are 24 volts, connect the batteries in series (negative of one battery to positive of the other). Run a wire from batteries to first switch, then to two of the lights and the other switch (in parallel). From the second switch run a wire to the third light, then connect all three lights back to the battery.
