- Add a battery and keep the same voltage. You can use a parallel connection to add as many batteries as you want and keep the voltage the same. I will demonstrate how in this video. Enjoy.
Check out one of my favorite Lithium LifePO4 batteries used in the video..

Your explanation of why its better to connect the pos and neg on different batteries when you have a parallel connection is exactly what i was looking for. Thank you.
Same here some you se then neg and poss in a line then some use the same side poss and neg but some use the oppasite side and its been a week working out why cos how do u ask google that lol
Thank you so much for explaining the cross connection of the RV load from positive of battery one to negative of battery two! I was searching all over TH-cam for someone to explain this.
Yep, this is how I thought it should work but when working with electricity and high dollar gear I always want to confirm with a pro.
Same. Was searching for the same answer 👌🏼
Great tip on crossing one batt to the other. This really helped me understand battery charge life
When I was in the army, my tank used a 24v system at 100 amps. 4 x 12v batteries connected in series-parallel. Often had a fireworks display when terminals were touched or the spanner hit the hull. Great video. Many thanks
Thanks for the tank battery info. That's pretty cool.
@@fullmoonadventureclub no worries. It was a Cheiftain AVRE (Armoured Vehicle Royal Engineers) a variant of the gun tank.
quick answer for all the people asking questions in the comments:
2 x 12v 5ah battery joined in PARALLEL = 12v10ah (double the CAPACITY)
2 x 12v 5ah battery connected in SERIES =
24v5ah (double the VOLTAGE)
Great explanation! Thank you
Thank you, just the information I was looking for because while I knew how to connect the batteries in parallel, I wasn't sure about how to connect to them. I kind of suspected that it would be better to do it like that and now I know it is and why. Great video. 👍
Nice video. Easily understood.
Good job Jim! This is what I needed.
Most Excellent! Thank You
Thanks for your great information ❤
Bro thank you very much for your wise advice this is what I will do for my yacht
Thank you very much for that video sir
Thank you👍👍👍
Great information, and thank you for the safety tip. Always wear eye protection, I had a car battery blow up in my face once,
Thanks!
i have two power queens and will do parallel.
do you have video on connecting two batteries with solar charge controller and inverter?
Question do i have to use the neg pole on the battery or i can use the truck body as the grounds for my inverter?
I have a question I have a Freightliner fl60 medium duty truck and it has four battery setup I want to wire up a accessories I added like a power inverter, stereo amplifier and train horn what battery should I wire them too
Thanks your good .👍
Any issue with connecting (2) (12)v batteries in parallel that are 122Ah and 114Ah? Both are same brand and type 29 but one has a 1 year warranty and the other a 2 year warranty. These are Walmart 29DC and 29DC Maxx.
Can you get the same parallel effect if you connect 2 - 12v batteries to a multi terminal block ?
can you add a 3rd battery on a motorhome? with parallel connection?
Does the 12v alternator charge both batteries ok? Thanks
Is it ok if the batteries are different capacities? I imagine it will "work" but will it have any negative consequences?
simple question for the people with knowledge about the subject:
i got 6 batteries, 12 volt and i dunno howmany amphours. In series. So roughly 72 to 80 volt or so....Gel batteries to power a scootmobiel.
I also got 2 gel batteries in my shed, came out an older type scootmobiel.
Is there a way to hook em up to the 6 batteries so to increase the amphours, if only for just a tiny bit?
The electric system of this scootmobiel can not handle more than what the 6 batteries put out (in series).
So, do i need to have 6 batteries parallel to the 6 that are already there, or can i get a bit more amphours by hooking up just 2 to the 6 that are already there?
Muchos Graçias for the reply, if any.
my plow truck uses 2, 12 volt battetys hooked in parallel and the truck electrical system is only hooked to one battety. the other battery has the plow electrical system attached. been running it 10 yrs like that and still have the same 2 batteys.
Can charge them without disconnecting the whole setup?
How do you take the power from this way . .as its registering the same on the multi meter. So i believe the idea is to double amp hours ? So how do i get double the amp hours Shown up , as my thinking on this if i watch TV FOR 1 hour on 1 battery ,, i should watch TV For 2 hours on joined batteries ? But i can not see how its monitored as it just shows 1one 12volt reading still ? Please can anyone explain ..
Would you mind answering if I have Two lead acid batteries, one at 12.5 and the other at 12.7 would it be ok to put them in parallel or should I up the 12.5 first(I don’t know how)
You're totally fine to hook those up in parallel with that difference in voltage. However, it is recommended that you use two batteries that are near the same age and have the same amp hour capacity. Not all batteries are the same.
Does it last twice as long?
Connect 2 batteries in parallel. Will one of the 2 batteries explode if one is 13.15v and the other is 12.5v
so(6)6volts batteries connected in parallel, as described, will still produce 12 Volts efficiently?
No. If you connect two 6 volt batteries in parallel your voltage will remain at 6 volts. If you would like to 6 volt batteries to produce 12 volts you need to connect them in series. I have a video on that as well.
how would I attach an inverter 12v to 120ac?
Which place the solar contact??
I’m not sure if you monitor your comments or not but I was wondering I have my two batteries set up the same way and I get about six hours out of them each day is there anyway to set them up to get more time out of them or do I need to upgrade to better batteries
I'm unaware of any different battery configurations that would give you better time. Better batteries is probably your only solution or adding solar.
Do all batteries have to have same amp rating or can you mix say 110 to 85 amp
Preferably, batteries that are going to be connected into one battery Bank need to have the same amp rating, be of the same brand, type, and age if it all possible. Matching the same amp rating is a must.
@@fullmoonadventureclub ok thankyou
What happens if i plug one 120Ah battery to another 165Ah battery in parrallel, does it damage my sinewave ups? I’m looking into doing this in order to maximize runtime
285Ah ?
Make sure both batteries are healthy, and voltage is the same when connecting them. should be no problem
@@yvindbruknapp1733 actually new setup now, one 150ah AGM battery aged 1 month and planning on getting another 150Ah AGM as well to plug it in parallel.
As mentioned, same voltage is the key. Actually I'm not an expert just that I "know" equal V is critical. I too wondered about any disadvantages to parallel connecting two batts of diff ah. Should "work" of course but there must be a reason we never put AA and AAA in the same device despite having the same 1.5V
Can you put a 100ah breaker switch in beetween the cables so if you want you can disconect one battery both my batteries are 100ah each leshure batteries wired the same as yours i just want to add a breaker switch bear in mind the breaker switch is 100ah and the combined batteries would be 200ah hoping someone can advise me .
They 100-amp breaker is fine as long as you only plan on pulling less than 100 amps of power. The main thing is you should match your breaker to the maximum amount of current that your wiring can handle. If your breaker is bigger than your wiring capacity and there is a short it could cause a fire.
Which Sid the solar contact
But what is the voltage of both batteries when the car is running..
Can I collect a 12v mopped battery with a 12v car battery
you should explain the battery system a lot better visually by where all the leads go. not using the multimeter at the end, be far easier to understand, other than that you did a great job
Sorry for my late reply back to you, When you put the two multimeter needles one Red and Black at the end of your video, you should have connected a Red and Black cables to where they were supposed to be, So people can see and understand better. If you think I was complaining about you, I was not, Sorry if you understood, Have a nice day, Stay Safe.
Agreed
How to connect it to the device if I am using one , where the wire must be connected ?
Connect the positive wire of the device to the positive terminal of battery number 1 and connect the negative wire of the device to the negative terminal of battery 2.
Is it okey to parallel a car battery by mixxing the old and the new battery?
It will technically work but will probably degrade the new battery prematurely. Both batteries will not equalize or hold the same charge properly unless they are both preferably the same type, brand, voltage, and capacity. It is best to start with two new batteries when dealing with lead acid batteries in parallel.
Thanks for the info sir
Do the batteries have to be the same rating ? Can you add a smaller amp battery with a higher amp ? Both 12 volts .
No you cannot it has to be the same
So we can join 2 2s battery and they still 2s
Is this safe to do without gloves?
This video needs a LOVE button instead of a like button. Guys freakin brilliant.
Why not have each battery stay on its own? don't I still get what I want out of both?
It doubles the run time of the batteries. Voltage stays the same buy capacity is doubled so you can say run trolling motor twice as long as with 1 battery
Do you recommend using 2 gauge wires and nothing else?
No you need to match the gauge of wire to whatever amount of power you're going to be moving from batteries to inverter and so on. 2 gauge wire can handle around 1000 to 1500 watts depending on the quality of The Wire and distance it will be run.
Why do my batt keep going dead
Can we joint 12v, 35 A and 90A batteries together ?
No. They have to be the same type battery with the same capacity
Can you contact me? Thanks!
What can I do for you?
@@fullmoonadventureclub Hey, thanks for responding. In lining up multiple batteries in parallel - like three or four - which batteries is it best to then attach your load and return wires to? Thanks again!… I think that was my question. Haha.. Good content! Like the channel.
@@justifiedesign attach your positive wire to the positive lead of battery number one and your negative lead to the negative terminal of your last battery.
@@fullmoonadventureclub Sounds good.
How do you charge the two batteries while in parallel connection
Same way he described to discharge them. Across the entire circuit by Pos on one batt and neg on the other batt.
