1. James CookAll of this makes my brain hurt. I wanna add 4 more batteries to the circuit of 12v each to increase amperage.

I dont mean to burst your bubble, but youll need more batteries to achieve your system. Assuming theyre both equal voltage and CCA ratings would I want to wire them in series or parallel and could this cause any issues with say blowing light bulbs or starting fires etc with the factory wired components or would I have to put a resistor before the fuse box in order to correct the issue and would that negate the benefit of having 2 batteries? I am off grid for more than 30 years and am I going to replace my bank of T105 (20) for the third time very soon. However I seem to have an extra problem, when left with the main breaker switch off the two connected in series slowly loose their charge.

I am a beginner in this kind of thing, so this might be a really simple question. For further technical assistance for your specific issue, you can email Tech@batterystuff.com. Batteries in series or parallel are only recommend to be the same type, so three 8V batteries are required for 24v system, and if you wanted a series parallel setup for higher capacity you could get another 3 to put in parallel. My old batteries were showing 12.7 after charging. MusthafaIf i connected 12v/50a battery with 3v/800ma, what is the output voltage and current?

Xlr8I have a sailboat and want to put in a 600amp battery bank for domestic use. What will that mean for the battery? Thanks so much. We only recommend connecting batteries that are all the same age, type, capacity, and put together to begin with.

Will be running rv fridge on 110 and a few cfl lights, laptop, led tv, dvd player. You should be reducing overall amp load running through cables and gaining cable life by doing so. They are hooked parallel. Some lithium batteries have built in restrictions which differ from manufacturer to manufacturer. With that in mind, if you are considering replacing the whole pack and going to a larger pack with more capacity you want to be sure your charger is about 10% of the amp/hr of your battery back for an effective charger. 2) Batteries joined together of different voltages and/or capacities will attempt to equalize, resulting in one or both batteries being drained and/or the other battery being overcharged. -2 Anderson connector sets for 4/0 wire 40.00 The originals are almost new, too (just spreading out paychecks!). Is this a sufficient charging method given that that 12V banks serve different loads and have different discharge rates?

In the end you may get more cycle out of a lithium battery, but the cost is also far greater than a typical lead acid of the same capacity. BatteryStuff TechIt is not recommended to mix and match battery of different type, age, or capacity. The top of the battery says 232AH.

Thanks for all the info.

David McNamaraI have six deep cycle batteries, a 3,000 watt inverter in my horse trailer. If the two controllers allow direct communication between themselves, use this to ensure they charge correctly in parallel. Mick. This is my second battery that this has happened with. It's alright if a terminal has more than one cable connected to it. We respect your rights to privacy and will not share your email information with anyone ever. When sizing the cable I would recommend following the battery isolator's instructions as they will generally have a chart covering the proper size cable given the distance to the auxiliary battery bank.

I am wondering if I can use a 12 V alternator to charge a 48 V battery bank. As you appear to be from Germany I would suggest contacting a local European supplier for your battery isolator.

Or is that just best practice for a connecting a load. I found your tread very informative. Can I use my existing 12v/60amp/4 bank charger to increase my charging amps to 30amp at 24v? The starting battery should only be used for starting purposes and should always be isolated from the deep cycle bank, otherwise you risk damaging the starting battery as they are not meant for deep cycle purposes. BatteryStuff TechThat would be a series parallel connection, and by doing so with three sets you would be multiplying the AH of the first set by 3. it has 12 individual, + & cables to treat each battery individually in the pack.

JimHello and thank you for the excellent article/site. SnazzyHelp me here. I would recommend using a step down converter to ensure that the batteries are drawn down evenly. What happens if 4 batteries of variable ratings are joined in series parallel? Please email us for such highly technical questions. Does it help if I reconfigure my good packs? Wire 4 x 12v 7.2Ah bats in a join series/parallel set-up to produce 10amp 24v output? but i still have a question. or do i have to charge it to battery #1 too?

A lot of our customers will utilize the same connection for both charging or discharging. What capacity batteries required for longest life, and how should I arrange them. When these pairs are wired together with ++ and (parallel), they keep the same voltage but now you have more capacity. How would I connect that to the 4 x 12v series/parallel configuration to achieve 35amp charging? Often times a 6v golf cart batteries are a prime example of similar capacities for in RV and some boat applications and will typically equal the same capacity of a 12v battery put in parallel. The camper will be placed off grid in SoCal where the sun is good. If more storage capacity is required, bigger batteries should be used, not more small ones. If the demand on the motor is constant, the lower available voltage will cause the motor to pull more amps in order to run properly. Andy, Shashank Sharmai have one circuit for mobile charger and one dynamo circuit both of them having different jumper wires can i connect them two the same battery of 12v and 7ah using their jumper cables, Mauriceif I have 24 2 volt 540 amp hour batteries in a series does that mean I would get 26 kw of power for my home per hour 48 volts x 540 amps = 25920 watts is that correct, JulesHi, i have four 6v 225ah batteries Im installing in my boat, the usual setup seems to be first to series two 6v batteries to achieve 12v then parallel the two series together however your diagram shows paralleling two batteries first then series to achieve 12v, What are the advantages/disadvantages of doing it the way you show?, Im very keen to set my setup like your diagram given my battery locations thanks. thanks for the response. I have 6 12v deep cycle batteries in parallel and I know I can charge them all with my 2amp and 12 amp chargers, but could I also charge them with something of higher wattage or voltage. I will be using a DC-DC C-tek charger or AC-DC C-tek charger depending on where I am.

One controller to feed one half. AguaniesoIs it required to install a 24V battery system when solar panels have 18V to 22V rating? You should have a 24v battery bank with 675 AH. Thanks. A battery bank is built up by connecting two or more deep cycle batteries together. but my voltage at idle is at 12.90 and when i rev pass 1000rpms it will go up to 14.9 where i set it. Tech and Jeremy Fear have thoroughly answered a lot of great questions. BatteryStuff TechIf done correctly and carefully, you should have a 24v battery system with 275 Amps. Are you ready to share your thoughtsand experience with us and many others. I must have done something wrong because both batteries did not charge each other while powering the computer, and battery charger through the inverter. I would suspect that over a grounding issue as I haven't heard of grounding issues causing such a problem. How long will my batteries support this until they die?

BatteryStuff TechWhile it is commonplace, it is not recommended to do so. Now they are saying it must have been a charging problem (with mixed batt voltages)and say we should replace all of the 6 6v batts with 5 8v batts and still use our 36v charger. And thanks. As with others above, I hate to spend $3,000 on new batteries because one has died. Is it safe to run 12 volt appliances off of one of the batteries. Often time a lithium battery of similar size has a lot of empty space withing the casing. with a 2V, 200 Ah battery for a 24V, 300 Ah capacity battery bank?

NatHoping this is a simple question. Can you suggest me how to isolate the two battery banks during charging. So, if your 6 volt battery is 240 AH, then the entire setup is 12 volts, 480 AH. The controller for the motor also has a current of 38A, so does it mean it's the max it can withstand, or the amount it works at? BatteryStuff TechDavid, so are there 4 batteries then? JBLooking for proof of concept validation before I start cutting and crimping cables: System will consist of 3 banks of: 4, 12v, 40 Ah LifePO4 Lithium batteries in series for a 48v, 40 Ah bank; all banks will then be run in parallel to bring amp-hours up to 120 Ah at 48v. ChrisI am wiring two 12v marine deep cycle batteries in series to provide 24v to some high powered LED lights on a boat.

For high use gates we see people collecting 3-4 days of energy in a single day. BatteryStuff TechIf you have both a series connection and parallel at the same time, you will cause a short to occur.

My diesel motor has a 65amp alternator. or it will make damage the battery. BatteryStuff TechWiring in series batteries of different capacities will cause an uneven discharge of the batteries.

Did I hose the batts in any way by connecting improperly? James Arthur LuggI have 2 six volt AGM batteries in series for the cabin of our Roadtrek that are in the engine compartment and are charged with three solar panels on the 5e roof of our rig. I know it might seem so simple its stupid. All you are doing it postponing the inevitable. Theyre house batteries in my RV and theyre wired in parallel. So what would the charge specs be also. JohnI made a survival power cart this past year, and I am glad I had it for Hurricane Sandy.

Johnnow Ill connect my friend hydraulics. Kudos are not enough. Well, by linking batteries together, you can increase the voltage, or the Capacity (AH / Wh), or both. Gpeg. SajibHello BatteryStuff TechRunning a wire from the middle of the parallel wires will work. BatteryStuff TechYou are correct, as the voltage increases the amperage will decrease in order to maintain the same total power. What about charging? If you are looking to add a deep cycle battery for storage purposes the proper way to add an auxiliary battery is through a battery isolator. Does the 4V, 4Ah one back flow to 1V,1Ah directly or it will go through 3V and 2V ones first? I would not use these panels on those batteries without a controller. The motor will run slower at 60 volts. This low-voltage DC electricity can also be converted to mains AC electricity by an inverter which boosts the voltage to 120 volts or 240 volts, commonly used to power larger electrical devices. If you have two sets of batteries already connected in parallel, you can join them together to form a series to create a series parallel battery bank. If it is 12 VDC, then parallel connections are recommended. BatteryStuff TechTwo of those batteries in series equals 7.4v, so unless your USB device is designed to charge that system voltage I would not recommend it.

(2) If the two batteries are wired in series, is there a way to make a connection to just one of the batteries to supply 12v to a second load? Therefore, you can connect two parallel connections in a series as you would two batteries.

I removed the leads to charge each batt separately with my 12V charger. Usually this is an AH (Amp Hours) rating. It's important to note that because the amperage of the batteries increased, you may need a heavier-duty cable to keep the cables from burning out. Jim MitchellI have just purchase a boat that has 12 6volt batteries for the house. BatteryStuff TechIf you are referring to connecting your batteries in parallel, then your battery system will be 12 volts with 600 AH. Therefore, if you need 230 watts of power, you can take it (through an inverter) from a 48 volt source at 4.8 amps. Would it be dangerous to run a cable in parallel off of the jumper cable connecting the batteries together?

But if your resting voltage reading is 2.8 volts or less, then the battery is discharged and needs to be re-charged. I thought that might be the different amperage is the problem, and after viewing this article my confusion increased. As long as the voltage (the pressure) is within safe range, then I see no danger in your proposed setup. GpegHi, thank you again for all of your helpful information.

And i was just wondering if a stock alternator that is 12 volt would charge them and where would i hook it up.. BatteryStuff TechVoltage and Capacity both increase, yes. It is the same method as you see above in the article negative terminal of the first battery to the positive terminal of the second battery, and then continue with the negative terminal on the second battery to the positive terminal on the third battery, and so on till you complete the string. Watts/volts=amps The freezer draws 4.5 amps at 115 volts. Heres what Im trying to do. i.e. Im sure they have a reason for it and maybe they can explain it to you, and then you can choose to proceed. What I want to achieve is charging from a single source, and an inverter to be able to draw current from all of the banks.

(That goes for both parallel and series connections.). Batteries can be wired or connected together in either series or parallel combinations, or both to increase the voltage or current capacity of the battery bank. Lead acid deep cycle batteries are the most dangerous part of any solar or wind power system. An electrical generator charges the batteries, usually during daylight hours for solar and the batteries supply the power when it is needed, often at night and during cloudy weather, so connecting batteries together to store this free solar energy is and important part of any off-grid renewable system.
