7 yrs later and still teaching.... Thanks for this video, very simple clear n useful... Question... Can I do this connection in parallel-series configuration, as here you guys did a series-parallel... Thanks!
If I make 2 packs of this parallel-series, will I get a 48v 400amp system, if so, I will I connect them? Pls your swift response is highly needed. Thanx! Your humble subscriber.
In series/parallel wiring , for figuring charging voltage. How many cells do I use in the multiplier 8cell x 3.4v. Or 16cell x 3.4v.? I have. 4. , 12.8v batteries .
This was the clearest out there I've come across, ty ♡ I have a question, I run a 12 volt system and am thinking of running it 24 volt ... four 12 volt 125amph agm batteries at the moment.... so right now my amp hours are 500 if I'm correct? But if I do a 24 volt they will be at 250? Which is better? The volts? Or the amp hours? Offgrid, northern mn
jo lee If your batteries are connected in parallel, you connect to the negative terminal on one end of the battery bank and the positive off the other end of the battery bank, never connect the pos and neg off the same battery in a parallel bank. Hope that helps. ✌🏼🇨🇦
@@CanadianEnergy Hi there. I have 3 , 12 volt 185 ah and one 165 ah 12 volt battery. want to increase capacity of my battery bank. how I have to do my battery connections? have a 2.2 kw solar system
to create a 12 volt 4 batt bank of old 12 volt batteries to run a power inverter pos to pos neg to neg down the line, where do the solar or batt charger clamps go? same as how u tested with the meter first and last battery?
Question: If you have a 7amp hr battery and connect it to a 48 hr amp battery (Both 12 volts) do you risk blowing the lower amp battery with to many amps going to it?...Also, if I get a 7 amp rechargeable battery and hook it to a stereo and plug it into your car cigarrette lighter (power supply) would it blow the battery?....Thanks
loser 3009 Usually series parallel sets are all connected to charge and discharge together, it depends what your voltage and configuration is. Hope that helps. ✌🏼🇨🇦
i have, 12 and 12 in parallel ,in series with another 12 and 12 in parallel to get my 24 volts. but can't monitor /balance, each of the 4 12 volt batteries. in your last configuration, you have ,12 and 12 in series ,in parallel with another 12 and 12 in series to get my 24 volts. will i be able to monitor /balance/ charge, each of the 4, 12 volt batteries in your last configuration?
immrnoidall we don’t think you will be able to do that, you can probably charge and monitor the 2 x 24V banks. If balancing and monitoring is a concern, due to multiple heavy cycles, our recommendation is to use larger capacity 6 volt batteries that are all connected in series, this eliminates the battery imbalance and multiple parallel string issues.
@@CanadianEnergy i am trying to prevent a single 12 battery ,from getting too low. when using your last configuration of ,[ 12 and 12 in series ,in parallel with another 12 and 12 in series to get my 24 volts ] would i see a single battery voltage across its +/- terminals?
hello sir. im in big trouble. i have connected 7 battery in parallel. its lifepo4 with each battery 6000mah. but im still getting the final mah as 6000. though by theory, i should get around 6×7 = 42000mah. can u explain why ? Although the voltage increased correctly when connected in series. So no problem there. Kindly explain.
What porpose is it to combine both series and parallel? Seems to me that you want 12V with 460AH in Parallel that gives you longer lasting power. Simple demonstration of different hook ups but No demonstration on why you want one or the other which is really what most are wanting the answer too...Right?🙄
Hi Let me make this clear and I hope you respond I have just bought 2 x 2000 w KRIEGER INVERTERS Plugged them onto 6 x 1000 ah connected in series at home and one blew up the other does not even work as it should WHY ? What size Inverter should you have if say the Voltage I tested says 64 VOLTS From the Solar to the Battery readings ? get back t o me please ASAP Troy
Without know what inverter or what batteries you are using, we can only hazard a guess that you have 12V inverters and you've put 12V batteries in series to get 64V into them. That would likely be why they don't work. If you put your batteries in parallel, you would be keeping the voltage to 12V. We would need to get far more information than what you've provided to be absolutely sure, but our strong recommendation is that you engage a professional solar installer to help you with your installation. It's far cheaper to hire an expert than to continue to replace expensive power electronics.
if i have 4 batteries and want to do a 24V system, is it better to hook them up into: 2 in series + 2 in series and those in paralel or 2 parallel + 2 parallel and those in series ? as allways there are folks that say the first is better and other say the latter is better ...
I would also like to know the answer to Broxin'e question. I have a 24v setup like his 1st example which is normally charged by a 24v solar array. I was thinking that if I wanted to top off the batteries with my 12v battery chargers (I have 2 of the exact same model), it might be easier to charge them if they were hooked up like example #2. Am I correct in thinking that I could charge both 12v parallel battery banks at the same time using the 2 chargers and maybe not even have to disconnect the parallel connection between the battery banks? Right now when I've topped them off, I break the parallel connection between the battery banks (so as not to create an imbalance), charge both 12v batteries in 1 series bank at the same time, then charge the other series bank then re-establish the parallel connection. Thanks in advance!
Matrix it’s recommended to use identical batteries when operating in series, if they are the same batteries there should be very little difference. For mismatched batteries .25 volts would be a maximum but they should also be the same capacity. Hope that helps. ✌🏼🇨🇦
I B If it was a series parallel connection it might be possible but when connected all in parallel there is going to be a big imbalance due to capacity difference. Hope that helps.
when creating a proper battery bank for power storage in an offgrid situation you want to use a parallel-series connection. so you can balance your batteries properly. 3.2v 200 AH with 3 batteries giving you 3.2 v 600 AH then you connect eight sets of those 3 battereis in parallel only in series giving you 25.6 v x 600AH = 15,260WH of power or just over 15 KWH of power in the battery bank with a proper balanceable battery bank. if you go series parallel you will not be able to balance the batteries properly and that is what most people do. they put together batteries into 24v or 48 volts then put those together to build up your AH totally messing up your ability to balance your battery bank. the reason most people do this is because they have 12 volt batteries available but today we use Lifepo4 batteries which are 3.2 volts and putting those together like I already pointed out in parallel series you will be able to set them up really well with a battery balancing system which will give you a lot of life in your battery bank without you loosing batteries because of one getting out of balance with another one. they will all stay in balance with each other using parallel series. I used 3P8S in my example. use that system and you will have batteries that will stay in balance for a long long time without the chance of going out of balance and blowing up on you or having a run away cell in your battery bank.
the other way around is what i see: Any 12 V li-po is 4x3.2 in series,then parallel the 12 volts bats; you sure par-ser is the best way? i see ser-par all over
Ok so given an qty of batteries hooked to say a solar array system. What is the best way to wire up that bank of batteries. For instance if I had say 12 batteries in a bank. Would it be best to wire the batteries in series in sets of 4 and then wire the 3 banks in parallel. Or would it be best to make it 4 banks of 3 ( wired in parallel ) then connected in series? How does parallel vs series affect the batteries when being discharged or being charged. My question comes from this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Rh9eEw-W3Lc.html Where someone, with supposed experience, says that the banks should be wired into 3 batteries in parallel and 4 banks in series.
How do I connect 10 batteries to 1 charger for Perfect Balanced Charging I am trying to connect 10x 100AH 12v Deep Cycle batteries to a true 10kw inverter. I also have a processor controller constant current 80AMP charger. I am planning to run a mobile office. I need 12v battery bank. All these equipment are brand new and I have them sitting in my garage. Initially I thought I will just connect all batteries in parallel. Connect the charger and load on opposite extreme ends. But after reading this article, www.iotaengineering.com/pplib/balancedcharging.pdf, I came to know that the charging current from charger, or the load current when running inverter is not equally distributed. In above article this method is explained under {Method 1: Balanced Charging}. I want to use Method-2 for perfectly balanced charging. I am not able to figure out so far how to connect 10 batteries using perfectly balanced charging method. So that every battery gets 4AMP when charger is supplying 80AMP current. I asked my nephew, who is fresh graduate electrical engineer worked for NASA, he was unable to answer this question. I asked my uncle, who is PhD Electrical Engineer, he was unable to help me. I find is so strange that all these people with degrees cannot solve this simple problem. I am sure, there is someone out there who is smart enough to figure this out. Please Help.
sam riaz am not certain there is a way to “perfectly balance” charge and load on 10 batteries in parallel and that is why we generally recommend fewer larger batteries to get to the same total amp hours of storage. My preferred way of connecting many parallel string is to make identical parallel cables, they must all be identical even if some seem longer than required. Bring all parallel cables to a busbar, one for positive and one for negative. You will then connect the charge and discharge lines to the busbar and this will help minimize imbalances in the charge and discharge. Periodic equalization charges (if the battery chemistry allows equalization) will help keep the batteries at the same state of charge. The heavier the cable and busbars in a battery bank like this the better. Thank you. ✌🏼🇨🇦
