Little question, How do we call that?

I am not sure I understood how to do this.

Use a battery monitor which measures the charge in and out of the battery. Okay thanks Let's admit I use this: Would it work? How would I connect it with the battery? Do I first have to connect it with charge controller? And where on it?

Okay, thank you very much!

Hello,So if I have a lead acid battery 12v and 60Ah, how can I know when it is 50% full? Which would mean I have to stop using it and let it charge again. On the charge controller you can see the volts but not the %, is it a device I can use to see in %, if yes, how does it work, how can I fix it to the battery? If not, how can I know using the volts?

Ohh okay thank you! And so for devices which tell you in% which are not expensive, you don't know? Last question: How does this work? Like how could I fix it to my 60ah battery? Really sorry for all these questions, I am just very curious😅

Okay thanks. How can I calculate it? Is it like you explained before?

Okay thanks, but it shows you the % or you have to figure out alone? Like with ...volts would I be at 50%? And so I can put this charger directly in my laptop, like I don't need anymore the charger I am using now or I still need it?

So I guess it is better to have 6v but 20Ah right? Because I can store more energy? So thanks to this device I can know how much "full" in % my battery is? Thanks again for your very well explained answers!

Okay, thank you very much for your reply! But I am not sure I understood everything about the car phone charger? How do I know which one I need? And how does it work? How do you know that it will take 10h to charge? Which calculation do you do? So I have better to use this kind of battery? It has 60Ah. And so which device do I have to use to know how much energy my battery has and when I am bellow 50%?

Sorry I wrote 2 times this topic, please respond to the other one.

Hello guys, I am a Swiss highschool student and I would like to buy a solar panel 100W, 12v. I am very curious about this field and I really would like to use in the future 100% renewable energy.😊So I need to go step by step and my first step is to buy a 100W/ 12v solar panel to can charge my laptop and my phone.So this solar panel is enough to charge a laptop right? Here are my other questions: For a 100W, 12V solar panel, do we need a charge regulator, a 12V battery, as well as a 300W voltage converter, from 12V to 230V (for example), to be able to charge a laptop ? If the solar panel produces less than 12V due to little sunlight, does the battery not store anything anymore because it is a 12V battery or can it still store? If it does not store, that would mean in this case, that I should take a battery with a lower voltage such as 6V for example? Can it then store enough energy or is it “full” very quickly? In this case, would that mean that the charge regulator and the voltage converter must also be able to accept 6V? How can I mesure the voltage of a battery? How long does it take ~ for a 12v battery to be fully full without using it at all? Also, I am not sure I understood everything about the inverter, which kind of inverter should I use for a 100W/ 12v solar panel? (I prefer the inverter than the DC power supply because it seems easier). Can it be like that if I want to charge my laptop? (Sorry it is written in french...)Also, so for the battery I have better to choose a 6v battery for my solar panel like this one?Or it isn't a good idea?( I would like an inverter and a battery cheap but which work quite well even if they are not expensive, if it is possible) Last question: How do you link several batteries together? These are my main questions and I apologize for bothering you with them. Have a nice day!🙂
