Need to power a 5th wheeler at night and air compressor for air tools during day and two deep freezers.

## 36 Volt Battery

I have a RV with two 12v amp batteries, giving me only amp hours to run the RV. Either that or they are on their way out. System powers a 3. When selecting one you just want to make sure that it exceeds the amp rating that is charging the batteries.

You question goes beyond our expertise here, I would suggest talking with a local mechanic for suggestions. I have a floor machine with four 6 volt batteries wired in series to provide 24 volts.

Connecting the 3 in series will add the voltage to 36, connecting the two sets will keep the voltage the same but increase the capacity. If I connect a charger to the grid and then to the batteries, would the charger have to be disconnected when the batteries were being used?

That would still be 12 volts.

Both batteries are approx. When you mix and match batteries outside of this recommendation there is a risk of damaging a battery pack. That ganesh idol makers in bangalore dating how most hook up their systems, but there are more complex system out there that can run the solar through an inverter chargers so solar power is primary over battery power.

Thank you for this very valuable service. Is it okay to connect 2 of these in parallel to increase the current? The proper way to charge an additional battery pack off an alternator would be to use a Battery Isolator, such as our Quick Power Amp Battery Isolator Bi In the automotive context, a voltmeter gauge displays the number of volts stored by the vehicle's battery.

I would would recommend contacting our Tech Department for suggestions. One bank is 4 12v batteries, the other is 3 12v: Can you hook up a 12 volt light to a 33cc scooter?

Has any one tried this? This will cause the new battery to fail over time, and could eventually bring down the whole battery pack. Linear Voltage Regulator A linear voltage regulator is a circuit that acts like a voltage divider, but automatically changes resistance to maintain a constant output voltage regardless of change in the current drawn from its output, or variations in the input voltage.

## Understanding Battery Configurations | Battery Stuff

How to hook up 36 volt battery meter, substitute the device as one of the resistors. How do you hook up two 6 volt batteries to get 12 volts? Why will a car crank over but not start with 12 volts of power until its hooked up to a jumper and it gets 14 volts or over then it starts right away?

I wanted to know how much voltage the amp is getting Danny Wean: If you plug a 2 pole breaker into two slots then you get outputs because L1 and L2 are adjacent to one another.

Thank you in advance. In regards to why the polarity has reversed it is often caused when the battery is fully discharged, and then charged back up in reverse.

Do you see a problem here? Question; will the increased amperage hurt any of the components in my truck, or is the extra amperage just being stored for easier engine starts and longer running components like fridge, microwave laptop,… without idling the engine?

Is this because the second batt is failing, is it normal to have a reverse polarity memory on the batt with positive to the neg post? In regards to Solar make sure you get a solar charge controller that is designed for Lithium, and then your solar panels go to the batteries through the solar charge controller.

Turn the batteries so that the positive and negative terminals are on the same side and next to each other. Can I charge each battery with my 12V alternator if I wire them on there own circuit without doing any damage to my truck? Where should I add the fuse s at the end of each bank AMP?

Thanks for the info Melvin: Is there a way to hook all 6 12 volt battery up to get 36 volt or can it only be done with 3? Many vehicles, particularly older cars, are equipped with only a dashboard light that illuminates when the battery voltage falls below a normal level.

Can I run a generator the same as I would a regular 12v system?

When first testing each one with a volt meter one had a normal polarity and 12V, the second batt had 10V and reversed polarity coming from the posts. Your videos are always very informative and clear, you are good at explaining things.

Another words if you accidental hooked the positive to the negative, and the negative to the positive, you can end up reversing the polarity if the battery was completely discharged. What is the best I can do? Get this charger, its 15 amps, it'll charge your battery up.

## Battery Bank Tutorial: Joining Batteries Via Series or Parallel for Increased Power

The two battery packs you have are of different capacity, so you are creating a situation where batteries are going to get overcharged.

I would suggest reading our article Solar Systems the Right Way. This all works fine. Any good solar setup will at minimum put double the daily amp draw back to the battery pack, and most will store up a extra day at minimum of energy.

Ta- da, instant electromagnet!!! Locate a bolt tightened into a panel. For example; connect the two wires onto two pieces of mteal or copper and put them in a glass of salt water, facing apart- not touching!

Thinking of adding a 3rd due to them draining quickly from the refrigerator turning on and off all day. CampRicco I have two battery banks. Single pole breakers in the panel board starting at the top, alternate between L1 and L2 all the way down to the bottom. In regards to adding another battery into an older bank… It is not advised.

Because if I connect the voltmeter directly to the positive and negative inputs of the amp, the voltmeter will be on at all times. How low can your volts go down before it gets dangerous for your electrical? Plug into here your phone car DC charger, or into the inverter your phone AC charger.

Please show me how i can calculate the duration it would last if i have an average load of W. I have disconnected the interconnect cables from the old batteries, but I am now getting an arc when I attempt to make the final connection between the batteries.

How many volts can you hook up to amp? Its not an AGM battery, but its a good flooded lead acid battery and will do the job.

We do sell inverter installation kits and depending on the one chosen it will come with a A or a A fuse based on the size of the inverter.

Or if both batts are perfect should the second batts have normal polarity on the charge?
