Excellent, concise video, exactly the kind of explanation I was looking for. Suggest to produce a video that explains the difference between Lithium ION and LiFePo4 batteries. In fact people seem to accidentally misnomer Lithium Iron and pronounce it as Lithium Ion (omitting the "R" in Iron) probably because they don't know the significant difference between the two. I have not been able to find someone who will explain the dangers of Li Ion and the advantages of LiFePo4 in a well-produced video. Then again, it seems people could care less, in which case the video wouldn't get any views, possibly a waste of time. Thanks
@Arminius thanks for your feedback. I find what you are pointing out very interesting, and you are definitely right that there seems to be a lot of confusion between the terminologies used and the characteristics of the the different types of Lithium-based batteries. I will let my brain chew on it a bit and come up with a proper video. Thanks!
Thank you. This is helpful. I wish to regulate the charging in a system that drains battery power really fast. What is required to make the charging relatively fast and not overcharge?
It would be interesting to understand what happens with a dead car battery, in my case a lead/acid one. My CTEK charger charged it from "dead" (2 leds out of 8) to full in a few hours, but it lost its charge until morning, and now it's staying at 2 leds for hours, and both the charger and the battery get hot. I can hear bubbling inside the battery. When is it a lost cause, and why ? This was bought new a couple of years ago then kept in storage where it deep discharged
Hi Jessie. Love your shows they are very professional. If I have 60vdc and 10 amps coming from my panels going into a 100v 40a mppt controller to a 12volt 200amp lithium battery at 50% charge(13v), what should the volts/amps going into battery? should I be getting roughly the same watts into batteries as going into controller minus inefficiencies.? thanks Clark
Dear Jesse thank you for sharing your knowledge with us ,wishing you health and prosperity .

Your video is very informative and precise. I want to know about flooded battery installed at home are placed at one place for long time un moved. Does moving/shaking them after regular interval have any affect on their life and efficiency?thx
Good question! Shaking/moving is probably not a good idea, since it could accelerate 'plate shedding' and possible short plates due to plate debris at the bottom moving around. Stratification of the elecrolyte is what one would generally try to avoid/reduce by regularly going through the absorption phase: In the absorption phase the bubbles in the electrolyte would mix the electrolyte and hence reduce stratification.
Please go into detail about charging LAB (flooded, AGM, Gel) arranged in strings of series-parallel. I have large AGM batteries repurposed from a data center that were never cycled I am using them for my off-grid solar at night. My inverter would prefer 36+VDC but will operate on 24+VDC. My batteries are 12V. I want to arrange them 3 in series and then two banks of three in parallel. I get VERY mixed information about how to use my charge controller to charge them during the day. Lots of information saying my middle battery in series will be damaged during load and unequal charging will happen. What is this all about? How do I (schematic??) arrange my batteries so they charge correctly each day. I live in Southern CA and have excellent true south exposure from sunrise to sunset for my panels.
Hi, I have had all my AGM batteries gassing away during absorption and wondering how I can reduce the gassing, the problem is that even though they are fitted with catalyst caps, the recombination is far to be fully effective, its seems that this catalyst is a bit of a gimmick. What to you would be the lowest voltage that is acceptable for absorption and how much can we compress the absorption time down to? It is really hard to find this information online.
Good info, thanks. What I wanna know is if a Lead-Acid Battery degrades after a full year of use and if you should change the float voltage on the solar controller to a lower voltage. If my Battery is working OK but can only charge up to 13.2v isn't it harmful to keep the float-charge-voltage at 13.8-14v?

A video topic I would like to hear your opinion about would be some detailed information on charging a deep cycle battery on a alternator. It seems to be the general consensus that is a bad idea, but I have never read or heard someone explain why, an alternator with single stage charger can't full recharge a deeply discharged battery. You explained how a 3 stage charger works but what does a single stage do? Jason
Hi Jason. As promised, here is my response to your question about charging your deep cycle house battery with your alternator. I hope it will be useful for you. [Time stamped, specific to your question] th-cam.com/video/TAEzCcayI0g/w-d-xo.html [Complete video] th-cam.com/video/TAEzCcayI0g/w-d-xo.html
here's a question: can you use your battery at any different stages of charging or you have to wait until float charging... my controller (solar charger controller) always indicate "MPPT" and I have not seen the "floating" stage yet. So I'm not sure when to safely switch to battery use. Thanks and more power.
Great video, very easy to understand! I’d like to see a video of your opinion on the different types of charge controllers (had a look at your channel but couldn’t find one)
A great suggestion, thank you for your message. There is indeed no video on this topic yet. I will make one and notify you once it is online. Thanks! Happy new year, Jesse.
Thank you for sharing I have a question can you talk about you know measuring yourselves and you know give us specifics like how like I'm not sure how to read the fractal meter so in other words what numbers should I look at how far apart do they need to be for me to equalize
Thanks so much for the video. Very informative. I have a Mastervolt 50A/3-channel charger, connected to 4x 6v lead acid batteries by Interstate, (2 other channels of the charger are for start batteries). Batteries about 3 yrs old, and never been equalized. My bad. The charger appears to be able to do only a poor job of equalization since it only approaches the equalization voltage and stays there for a short time. And Interstate indicates that equalization should be done for 2 hrs at the equalization voltage. Can you advise any special equipment or setup that would allow for proper equalization to be performed on the batteries?
Hello D, thank you for your message. It is good to hear you enjoyed the video. As for your question: Do you know whether you can adjust the settings in your charge controller?
@@SolarSolution You can only adjust the equalization voltage. You cannot adjust the duration of how long the charger stays at the equalization voltage. I am actually considering the purchase of a DC power supply that has voltage and current settings so that I can adjust what is applied to the batteries during equalization. I realize that I will need to ensure that the batteries are isolated from all loads and chargers when I apply the DC power supply output.
Hi Jesse. You mentioned that you can connect a temperature sensing device to your charge controller wirelessly. Can you share an example of a wireless temperature sensing device and how to connect it? And also a hard-wire connection like you also mentioned. Thanks.

Hi Handis, thank you for your message. I will upload a separate video on battery capacities soon, I am sure this will answer your questions. If not, just let me know.
Wow, great explanation! Finally I understand the differences! :) I do have one small question though, if you have time...my solar charge controller is pre-set to go to floating charge at 13.8V and to equalizing charge at 14.6V, however the label on my battery says floating charge should be activated at 13.5V and equalizing at 14.1. Do I have to be concerned about these differences? Unfortunately I can only change the preset by adding a bluetooth controller, which is very difficult to get here in Peru. Please let me know if you think that's really necessary or if I'll be just fine with the preset settings! Thank you! (btw: I'm not sure if it matters but I actually run two of these batteries in series because my system runs at 24V).
Thank you for your message Gerald, I am glad to hear you enjoyed the video. And nice to hear from somebody in Peru!. Unfortunately I cannot provide you with technical advice through the TH-cam comment section. Sticking with the manufacturers recommended voltage settings is often wise. Overcharging a battery can [among other things] lead to accelerated aging, case bulging, and excess loss of electrolyte. This being said, the flooded lead acid battery are less sensitive to overcharging [and other forms of abuse], compared to the AGM and GEL types. I hope this helps, if not you can contact me directly through the main website. Good luck! Jesse
@@SolarSolution Great, thanks for the quick reply! With what you said in mind, I will try to get the bluetooth extension, but at the same time not be worried about my batteries until I get it (probably in a couple of months)...Thanks for the advice! Have a great day!
You are welcome Gerald, glad I could help. I wish your bluetooth extension will arrive soon! Would be nice to hear how it turns out. All the best, Jesse.
Maybe you could also mention that a plastic mixer could be placed in each cell of a large wet lead-acid battery to stir the electrolyte periodically without causing the gassing and shedding, which would slightly simplify charging and extend battery life.
Hi Lars, thanks for your message. It is good to hear you enjoyed this video. You have an excellent question regarding de-sulphation devices: I discuss this in the following video I shared: th-cam.com/video/clVrcG8jV7Y/w-d-xo.html Let me know if you need additional information! All the best, Jesse.
Could you make a video about classified zones of battery rooms because of the hydrogen emission of the batteries. You said in the video that we may install the charge controller in the same room but the classification of the local containing the batteries requires an Ex protection mode that should be considered in the controller.
Hello friend, I'm writing from Portugal, I really liked your video, I wanted to ask a question about what is happening to me in my off grid system, 2 or 3 days ago I put my inverter to equalize to 31.4v, but it just arrives at 30.6v, and it doesn’t go up, which may happen, today I did the same thing and the same thing happens, the voltage doesn’t go up, I have 12 batteries (2v cpzs 930AH) only have 9 months of use ... hope you can help.

I have seen some dead battery pb battery recovery with a spot welder- can you please elaborate on this topic- the voltage and current figures on this spot welders are way higher than recommended but I have seen this method work many times. What are the pros and cons to this method ( except the safety aspect of course) And would it suit any type of pb battery or just flooded due to the need for removing the caps for releasing the pressure and topping up water?

As for the second part of your message, could you perhaps clarify your question a bit more: What is it that you want to learn? Thanks. Jesse
HI i want to ask a question because i am confused i have 8 6v 225 amp us lead-acid battery connected for 24v system 2 strings of banks in parallel make it 450 amp. and also a flex max 60 amp charge controller. can you tell me the correct settings for the absorption float and Equalization please and thaks
Yes Sir, I have checked the battery specification they mentioned only bulk and float voltage and did not mention the equalizing voltage and it's period.
Hi I’m not very smart I just purchased a electric motorbike lithium ion battery it says something like “once light turns green and fully charged allow float charging for 1-2 hours does this mean leave it plugged in when it’s full charged for 1-2 hours 😅
Yes, First stage bulk max rated charging up to 20%ah rating. They probably advertise how fast the green light comes on. They say float but I bet you its the absorption stage where the charge controller lowers the current due to the first stage completion re battery voltage and slowly finishes the charge till float (100%) as the video explains. You could test using a dc amp clamp. Or possibly using a regular volt meter set to dc, unplug the charger after the green light comes on and check the bikes battery voltage by touching your leads to the harness connections for your bike. Plug it back in for 2 hours and then check the voltage again. That reading should be close to your float voltage. Find the nominal voltage (lower than the green light value) the factory says the battery is and subtract from your float voltage (highest value). Example: Lets say you get get .5v difference (that's usually what i get from a single cell 18650) from nominal (shipping factory voltage) to float. Divide by 10 would be .05 so if i'm right your green light came on after 80% charge meaning .05 x 8 = .4 volt increase, in this example, from nominal voltage would be 80% and another .1 volt (20%) increase would be the float charge. Also if you know the battery cell make up you can find the battery factory voltage and see how many times they ran it in series to come up with the voltage rating they provide. So if its 18650 cells the voltage is I think 3.7v lets say if your bike says 48v then the batteries ran in series 13 times and the voltage more accurately would be 48.1v. So knowing the cells really helps make this test for more accurate. That .1v could mean 20%. Sounds crazy but if you run it in series 13x's that .5 x 13 = 6.5v divide by 100 = .065 that means .1v may only be about 2% of a higher voltage system. That sounds more like it. I could be wrong but I doubt it.
It is mentioned the charge current is a function of the Ah rating of the battery, but how does the charger know the Ah rating of the battery? How does a battery charger differentiate between 100 Ah battery and a 200 Ah battery?
It doesn't. He said that when it reaches a certain resistance that it triggers something in the circuitry of the charger to start the absorption process. The absorption charge rate could be a preset amperage value in your charger common for your type of battery (doesn't matter the ah). Only after it reaches a certain time or the amperage reaches an almost equilibrium state that threshold is met and you have reached float value. The charger should stop charging after this? But we know my cheap lead acid charger will keep charging at the 2a setting i selected and bubble up excess energy from the battery until you unplug it. Now ah rating is important because you dont want to charge it faster than the 20% ah rating for your battery. If you pick up a 5a output charger and charge a 25ah battery that would be 20% the max charge rate you can safely use. You need to check the absorption rate of the charger for compatibility with your battery. I got a battery cooking now I need to check on. Nothing smart about this one. I was going to add that is why I start my charger on a high setting for a low battery and after it reaches a certain voltage around 80% of float value I turn it down to the lowest setting and this has always gave me a strong car battery. It does give me a green light so maybe it does shut off I dont know. I've had some bad batteries come back to life after a really slow charge for extended periods kinda resets them or something. I think they call it battery conditioning.
what's the story of percentage meter? even when fully charged, my liquid acid new battery is showing about 50%. And also - can my solar charge controller receive also input from a wind turbine on top of the two solar panels it gets and still manage the charging or do I need a separate controller for the wind turbine (assuming both turbine and panels do not exceed the max capacity the controller can handle)
Hi Yoramedia. Thank you for your questions. I have a script ready for a video on State Of Charge indicators like the one you are mentioning, so I am sure this will answer your questions. The video will follow in the coming weeks. It would be a bit challenging to explain the topic in this comment only. As for the the charge controller question, I would definitely recommend to have a separate charge controller for your wind generator. I hope this helps, enjoy!
Why does a battery drops in voltage right after charging for Ex after float 26.6 volts itvdroos down to 23.3 right after charging ? I'll aporeciate if you could Answer myvm questions.thanks already
Hi Ashley, thanks for your message. Imagine that you are inflating the tire of your bicycle: While you are pumping, the pressure in the pump itself is quite high, and forces air into the tire. The pressure of the tire will increase, although the pressure in the pump will still be higher than that of the tire. Similar to inflating your tire, you will need a higher voltage from your charging device, in order to "inflate" your battery. When you will stop charging, you will now see what the actual "pressure" in the battery is. The voltage you are seeing during a charging cycle is the voltage produced by the charging device. I hope this helps! Jesse DISCLAIMER: Don't try to charge your battery with your bicycle pump :)
Hi Ashley, thanks for your question. There can be several reasons behind this effect, I would need additional information in order to answer your question. The settings in the inverter would be the first point of interest. Good luck! Jesse

Hello Anil, thank you for your excellent list of questions. I will create a dedicated video on this, and let you know once it is online. All the best for now, Jesse.
What would happen if you used a dc to dc converter instead of a normal controller for solar? They can accept variable input and the output can be set to a specific voltage. Why not set it at the float voltage and save the money for a controller?
I did find this: Recharging deep-cycle batteries with a charger using a constant voltage or a fixed charge algorithm can, over time, lead to a condition called stratification. Stratification occurs when the acid in the electrolyte separates from the water and settles to the bottom of the battery causing damage

Hello Robbert, thanks for your message. It is good to hear you enjoyed the content. For personal advice you can contact me through www.solarsolution.co/contact
thats simple straight forward absorbed to my mind .. great explained
much thanks
'Absorbed to my mind', nice one! Thanks for your message, it is good to hear the video was useful for you.
Thank you that was very clear and I learned a lot about the stages of charge 👍
A video topic I would like to hear your opinion about would be some detailed information on charging a deep cycle battery on a alternator. It seems to be the general consensus that is a bad idea, but I have never read or heard someone explain why, an alternator with single stage charger can't full recharge a deeply discharged battery. You explained how a 3 stage charger works but what does a single stage do?
Jason
Hi Jason, thanks for your feedback. An excellent and valid question, I will share a video on this shortly!
@@SolarSolution I will be looking forward to it thank you 👍
Hi Jason. As promised, here is my response to your question about charging your deep cycle house battery with your alternator. I hope it will be useful for you.

Great video!! It'll help program my new voltage regulator for my rv!! Thanks again!
Great to hear!
here's a question: can you use your battery at any different stages of charging or you have to wait until float charging... my controller (solar charger controller) always indicate "MPPT" and I have not seen the "floating" stage yet. So I'm not sure when to safely switch to battery use. Thanks and more power.
Great video, very easy to understand! I’d like to see a video of your opinion on the different types of charge controllers (had a look at your channel but couldn’t find one)
A great suggestion, thank you for your message. There is indeed no video on this topic yet. I will make one and notify you once it is online. Thanks! Happy new year, Jesse.
Thanks Jesse. Great video! Can't wait for the Lithium battery version! ;)

Glad it was helpful!
Thank you sir.we learn so much all in your video
Hello Wilfredo, thank you for your message. I am glad to hear you appreciate the videos. Keep on learning! All the best, Jesse.
Thank you for sharing I have a question can you talk about you know measuring yourselves and you know give us specifics like how like I'm not sure how to read the fractal meter so in other words what numbers should I look at how far apart do they need to be for me to equalize
An excellent question, thanks! I will share a seperate video on this.

Thanks so much for the video. Very informative. I have a Mastervolt 50A/3-channel charger, connected to 4x 6v lead acid batteries by Interstate, (2 other channels of the charger are for start batteries). Batteries about 3 yrs old, and never been equalized. My bad. The charger appears to be able to do only a poor job of equalization since it only approaches the equalization voltage and stays there for a short time. And Interstate indicates that equalization should be done for 2 hrs at the equalization voltage. Can you advise any special equipment or setup that would allow for proper equalization to be performed on the batteries?
Hello D, thank you for your message. It is good to hear you enjoyed the video. As for your question: Do you know whether you can adjust the settings in your charge controller?
@@SolarSolution You can only adjust the equalization voltage. You cannot adjust the duration of how long the charger stays at the equalization voltage. I am actually considering the purchase of a DC power supply that has voltage and current settings so that I can adjust what is applied to the batteries during equalization. I realize that I will need to ensure that the batteries are isolated from all loads and chargers when I apply the DC power supply output.
Hi Jesse. You mentioned that you can connect a temperature sensing device to your charge controller wirelessly. Can you share an example of a wireless temperature sensing device and how to connect it? And also a hard-wire connection like you also mentioned. Thanks.
Finding the settings for a 48 volt 540 amp hr lead acid forklift battery for charge controller settings. 25,920 watts what's the best amps to recharge.
Thanks for a good video. I would like you to explain if is possible to do equalisation using solar pv
Great suggestion!
thanks for useful information. by the way, does the battery have high AH means last longer than low AH, including discharging time and lifetime?
Hi Handis, thank you for your message. I will upload a separate video on battery capacities soon, I am sure this will answer your questions. If not, just let me know.
very good simple explanation
Glad you think so Michael! Thanks, Jesse
Hi, why does AGM & GEL batteries do not support equalization
These batteries have different physical and chemical structure than lead acid type
For a CTL70- 12V what is the battery charging voltage ?
Do we have to remove the caps while equalizing
Great video can't wait to see more 👍
Thanks Chris, it is nice hear you enjoyed the video. One new topic every week, I will upload the next video in a few hours.
Wow, great explanation! Finally I understand the differences! :) I do have one small question though, if you have time...my solar charge controller is pre-set to go to floating charge at 13.8V and to equalizing charge at 14.6V, however the label on my battery says floating charge should be activated at 13.5V and equalizing at 14.1. Do I have to be concerned about these differences? Unfortunately I can only change the preset by adding a bluetooth controller, which is very difficult to get here in Peru. Please let me know if you think that's really necessary or if I'll be just fine with the preset settings! Thank you! (btw: I'm not sure if it matters but I actually run two of these batteries in series because my system runs at 24V).
Thank you for your message Gerald, I am glad to hear you enjoyed the video. And nice to hear from somebody in Peru!.
Unfortunately I cannot provide you with technical advice through the TH-cam comment section. Sticking with the manufacturers recommended voltage settings is often wise. Overcharging a battery can [among other things] lead to accelerated aging, case bulging, and excess loss of electrolyte. This being said, the flooded lead acid battery are less sensitive to overcharging [and other forms of abuse], compared to the AGM and GEL types.
I hope this helps, if not you can contact me directly through the main website.
Good luck! Jesse
@@SolarSolution Great, thanks for the quick reply! With what you said in mind, I will try to get the bluetooth extension, but at the same time not be worried about my batteries until I get it (probably in a couple of months)...Thanks for the advice! Have a great day!
You are welcome Gerald, glad I could help. I wish your bluetooth extension will arrive soon! Would be nice to hear how it turns out. All the best, Jesse.
Maybe you could also mention that a plastic mixer could be placed in each cell of a large wet lead-acid battery to stir the electrolyte periodically without causing the gassing and shedding, which would slightly simplify charging and extend battery life.
I want more information about charging
Hi Abiezer. Can you provide more details about what kind of charging topic you are interested in.
What should be the equalisation voltage of floaded battery. For 48v system
I recommend following the manufacturers guidelines. Thanks!
Thank you for all that helpful information! It would also be interesting if you said something about desulphation devices like "megapulse".
Hi Lars, thanks for your message. It is good to hear you enjoyed this video. You have an excellent question regarding de-sulphation devices: I discuss this in the following video I shared:
th-cam.com/video/clVrcG8jV7Y/w-d-xo.html
Let me know if you need additional information! All the best, Jesse.
Could you make a video about classified zones of battery rooms because of the hydrogen emission of the batteries. You said in the video that we may install the charge controller in the same room but the classification of the local containing the batteries requires an Ex protection mode that should be considered in the controller.
Hello Walid, thanks for your suggestion. I will add it to the list! Jesse
Hello friend, I'm writing from Portugal, I really liked your video, I wanted to ask a question about what is happening to me in my off grid system, 2 or 3 days ago I put my inverter to equalize to 31.4v, but it just arrives at 30.6v, and it doesn’t go up, which may happen, today I did the same thing and the same thing happens, the voltage doesn’t go up, I have 12 batteries (2v cpzs 930AH) only have 9 months of use ... hope you can help.

Hi, im new in this, is SLA battery the same as a AGM battery?
I also seen some video they did revive a SLA battery by putting battery water inside it, does a SLA battery a dry battery, by putting battery water would damage it?
Thanks for your explanation.
What about battery electronic desulfators?
Do they actually work?
Or only the hi end professional ones do?
I have seen some dead battery pb battery recovery with a spot welder- can you please elaborate on this topic- the voltage and current figures on this spot welders are way higher than recommended but I have seen this method work many times.
What are the pros and cons to this method ( except the safety aspect of course)
And would it suit any type of pb battery or just flooded due to the need for removing the caps for releasing the pressure and topping up water?
Thanks in advance for your reply 🙏

Yes Sir, I have checked the battery specification they mentioned only bulk and float voltage and did not mention the equalizing voltage and it's period.
It's 12V Hyundai tall tubular battery 155 AH.
Hello, etai solar battery 200ah 3pcs not equal voltage how does it make?plz answer me.11kw inverter 3pcs connect to battery.
Hi I’m not very smart I just purchased a electric motorbike lithium ion battery it says something like “once light turns green and fully charged allow float charging for 1-2 hours does this mean leave it plugged in when it’s full charged for 1-2 hours 😅
Yes, First stage bulk max rated charging up to 20%ah rating. They probably advertise how fast the green light comes on. They say float but I bet you its the absorption stage where the charge controller lowers the current due to the first stage completion re battery voltage and slowly finishes the charge till float (100%) as the video explains. You could test using a dc amp clamp. Or possibly using a regular volt meter set to dc, unplug the charger after the green light comes on and check the bikes battery voltage by touching your leads to the harness connections for your bike. Plug it back in for 2 hours and then check the voltage again. That reading should be close to your float voltage. Find the nominal voltage (lower than the green light value) the factory says the battery is and subtract from your float voltage (highest value). Example: Lets say you get get .5v difference (that's usually what i get from a single cell 18650) from nominal (shipping factory voltage) to float. Divide by 10 would be .05 so if i'm right your green light came on after 80% charge meaning .05 x 8 = .4 volt increase, in this example, from nominal voltage would be 80% and another .1 volt (20%) increase would be the float charge. Also if you know the battery cell make up you can find the battery factory voltage and see how many times they ran it in series to come up with the voltage rating they provide. So if its 18650 cells the voltage is I think 3.7v lets say if your bike says 48v then the batteries ran in series 13 times and the voltage more accurately would be 48.1v. So knowing the cells really helps make this test for more accurate. That .1v could mean 20%. Sounds crazy but if you run it in series 13x's that .5 x 13 = 6.5v divide by 100 = .065 that means .1v may only be about 2% of a higher voltage system. That sounds more like it. I could be wrong but I doubt it.
It is mentioned the charge current is a function of the Ah rating of the battery, but how does the charger know the Ah rating of the battery? How does a battery charger differentiate between 100 Ah battery and a 200 Ah battery?
It doesn't. He said that when it reaches a certain resistance that it triggers something in the circuitry of the charger to start the absorption process. The absorption charge rate could be a preset amperage value in your charger common for your type of battery (doesn't matter the ah). Only after it reaches a certain time or the amperage reaches an almost equilibrium state that threshold is met and you have reached float value. The charger should stop charging after this? But we know my cheap lead acid charger will keep charging at the 2a setting i selected and bubble up excess energy from the battery until you unplug it. Now ah rating is important because you dont want to charge it faster than the 20% ah rating for your battery. If you pick up a 5a output charger and charge a 25ah battery that would be 20% the max charge rate you can safely use. You need to check the absorption rate of the charger for compatibility with your battery. I got a battery cooking now I need to check on. Nothing smart about this one. I was going to add that is why I start my charger on a high setting for a low battery and after it reaches a certain voltage around 80% of float value I turn it down to the lowest setting and this has always gave me a strong car battery. It does give me a green light so maybe it does shut off I dont know. I've had some bad batteries come back to life after a really slow charge for extended periods kinda resets them or something. I think they call it battery conditioning.
what's the story of percentage meter? even when fully charged, my liquid acid new battery is showing about 50%. And also - can my solar charge controller receive also input from a wind turbine on top of the two solar panels it gets and still manage the charging or do I need a separate controller for the wind turbine (assuming both turbine and panels do not exceed the max capacity the controller can handle)
Hi Yoramedia. Thank you for your questions. I have a script ready for a video on State Of Charge indicators like the one you are mentioning, so I am sure this will answer your questions. The video will follow in the coming weeks. It would be a bit challenging to explain the topic in this comment only. As for the the charge controller question, I would definitely recommend to have a separate charge controller for your wind generator. I hope this helps, enjoy!

Good video, dude
Thanks Smokey Joe, it is nice to hear that. All the best, Jesse.
Why does a battery drops in voltage right after charging for Ex after float 26.6 volts itvdroos down to 23.3 right after charging ? I'll aporeciate if you could Answer myvm questions.thanks already
Hi Ashley, thanks for your message.
Imagine that you are inflating the tire of your bicycle: While you are pumping, the pressure in the pump itself is quite high, and forces air into the tire. The pressure of the tire will increase, although the pressure in the pump will still be higher than that of the tire.
Similar to inflating your tire, you will need a higher voltage from your charging device, in order to "inflate" your battery. When you will stop charging, you will now see what the actual "pressure" in the battery is.
The voltage you are seeing during a charging cycle is the voltage produced by the charging device.
I hope this helps! Jesse
DISCLAIMER: Don't try to charge your battery with your bicycle pump :)
Thanks a real illuminating video
Thank you for your message Mujahid, it is good to hear you enjoyed the video. All the best, Jesse
Why does the Inverter goes from bulk charge to float charge without going to Absorption stage ???
Hi Ashley, thanks for your question. There can be several reasons behind this effect, I would need additional information in order to answer your question. The settings in the inverter would be the first point of interest. Good luck! Jesse

What would happen if you used a dc to dc converter instead of a normal controller for solar? They can accept variable input and the output can be set to a specific voltage. Why not set it at the float voltage and save the money for a controller?
I did find this: Recharging deep-cycle batteries with a charger using a constant voltage or a fixed charge algorithm can, over time, lead to a condition called stratification. Stratification occurs when the acid in the electrolyte separates from the water and settles to the bottom of the battery causing damage
