nice increase in skills man. I watched this right after watching ur older foldable solar charger and was like man he should of done parallel and used a clear case to store everything. And use ampere to get an accurate charge reading. Holy hell if u didnt do all 3, lmao good job sir.
Very good!!! You make high quality videos!! I'm your age and I would love to learn more from you. Keep going as you go !! A big hug from a Portuguese from Portugal. Obrigado
By the way, if you are reading this comment, I would like to say that I also have a CZcams channel and I would like your mega support in the comments box. Channel link: czcams.com/channels/gs6JV2sIaWd3ClaHKfMaqw.html
Nice work, and tank you for sharing this project. Caution!!! be-careful when using this types of batteries to an outside temperature exceeding 60 degrees Celsius, it may result to fire or explosion. Better keep the box with a battery or electronics under a shaded environment or indoors, chemical reaction can put your safety in danger from both batteries and the electronic components.
Thanks for your safety advice, I'll consider that! Yes, it's best to keep batteries out of reach from direct sunlight, I usually place a cloth over the power bank while the panel charges it. Thanks for watching!
Hey, its me again, I've gotten up to the part where you connect the arduino up. (the solar panel, battery, and sunflower is connected up) and to test if it is working I plugged the charging thing into the sunflower and tried it out, but I am getting no signs of charge??? Wondering if I need to connect the arduino for it to work or its just a technical issue on my end. Thx
Hi there. You don't need an Arduino like I used in my project to get your power bank to charge. The Arduino and display were used just for displaying the battery level. Try measuring your circuit with a multimeter to detect a rise in voltage in the battery. Also, what "sunflower" are you using? If you could somehow show me your circuit, this would help me to be able to help you. Thanks.
That's not true, as long as you wire them parallel, matching only has to be done with serial wiring. You could wire 3 different panels in parallel, then wire those in series with a matched trio.
@@DoctorMangler how do you match them when the panels are not of the same rating there will be slight changes in Voltage or Current with panels of different ratings connected together your output efficiency even if you wire them in parallel would slightly be affected.
@@giovanninongbri2250 Changes in voltage are already accounted for, his panels are all 6v. The amps add up. So he's got a 250ma panel, and a 60ma panel. Being they are all 6v, he now has 310ma. Amps do not have to be matched, volts do, in this application at this scale.
@@giovanninongbri2250 Aren't we talking about this guys 6v project? Number of cells don't matter, 36 cells no problem. His panels, as he stated were all 6v. So the amps add when wired parallel.
Hi. Thanks for your comment! I did that implication because 3.7V is the voltage of one battery that the board only accepts. Also that the connection between two batteries had to be parallel to double the capacity (mA) and keep it voltage the same (3.7V). Yes, I used thick copper wire to join the remaining two terminals. Cheers, Max
Hey!, doing this for my school project, got some questions to ask. Does the output voltage of the solar panels matter? like does the sunflower sort that problem out? also is 900amps recommended or needed. Thank you.
HI there. Yes, the output voltage of the solar panels must be 5 or 6V and no higher or lower. the 900 milliamps (or 0.9 amp) is the minimum required current to charge up the batteries through the solar charge controller board. Cheers.
sorry for instance can i find a cable that instead of a usb a output its perhaps a usb c line that only connects power? im trying to avoid a second cable and just be able to plug the cable from the panel directly to a portable battery to start charging it@@MaxImagination
Hi there. I typically use 24AWG wire, works fine for making most of these gadgets. No diodes needed for the parallel panel configuration, as the mppt board already has them. Cheers, Max
Hi there max and the comments section I was wondering could you add one more battery and make it 6000mh and could you give me tips on how to build one just without the display and lights
Hi there. Sure, just add another cell (battery of the same voltage) in parallel with the rest of the pack to increase capacity. If you want to build one without the display and lights, simply don't include them in your circuit. Cheers.
Hi Alex, thanks for your comment. Yes it is possible. I only did the programming with my kind of parts since I didn't have one of these battery level indicators which is better: amzn.to/3lefXGs
@@MaxImagination thank you for the reply, i also want to ask ,if i can't do the programming parts what features (just like in the video) can i not include ? because me and my groupmates plan to make a solar powered bank but that's our only goal and we want to lessen our expenses... thank youu
You're welcome. Yes, there's a way. You may remove the need of the microcontroller board (Beetle) as well as the battery indicator module. These you won't need to make this a minimal functioning solar power bank. Hope this helps, cheers. If you appreciate what I do and would like to show some support, I'd be grateful if you contribute to my work with a coffee - www.buymeacoffee.com/MaxImagination
Purchasing every single part linked in the description, all up it would cost you $45 US including DFRobot part links. Not purchasing through DFRobot links, materials may cost you around $20. Cheers, Max
Hello Max, just curious, what are your plans for the future? What do you plan tu study. If you don't feel like answer my question, don't do it. Great project.
Hi Regina, interesting you ask :) I do have some plans in the future, 1st, staying self-employed, studying electronics and mechanical engineering, I'll probably have this channel and keep posting videos as long as CZcams still exists and keeps their platform running. Thanks for you comment! :)
Awesome Job lots of thinking on how to fit all the components in a small sealed box 🙌🏻🔋
Thanks a lot! Yup 😅😃

Bro can we add more batteries???
Btw very nice portable life saving project👌
Yes you can - in parallel. Thanks for your comment!
Amazing idea max

would you happen to know how to wire it to a usb output so i can plug the panels into a battery bank?
It already has a USB output (1A) that can have a USB cable plug from into an external power battery bank.

Excuse me Mr ,Does the solar get the thunderstorm or not …
Hi there, the solar panels should not be kept outside if you start to see dark clouds with rain. It shouldn't be exposed to thunderstorms, no.
