I am really sorry for that.I will update here when it will be completed.Yes I will send a mail.Keep in touch.I don't know about $4 kit.But the controller what I know is vary from $ 24 to $ 50.
Glad you like it.Thanks for your valuable words.
I don't know if there is a way to turn any laptop parts to the LCD controller.Thanks for your appreciation.
Thank You.You can download the code from the following link.https://www.instructables.com/id/DIY-Arduino-Batter...The code (.ino file ) is attached at the bootom.
Glad you like it :)
Congrats !Dude your work work is excellent !
Thanks !The charging algorith for lithium battery is different.So my code will not work.You need a 3S balance charge for charging your battery pack.
You can use the same code.It will work
Glad you like it.

HiI am very happy to know that your son is interested on this project.I don't have any eBay account.I will suggest to make the circuit on a perforated board as explained in this Instructable step-9 .During the making, if you face any difficulty, I am ready to help.If you still interested to take the PCB, I can send it through post.But the problem is that it will take lot of time to reach.
No I don't have. I can send the PCB and components excluding the enclosure and battery
Used by the load
You can use this project to monitor the Solar Panel power.Just you have to connect the current sensor and voltage divider towards the solar panel instead of battery.

Congratulation !Thank you so much for sharing your build picture.
It will work.No worry.
I have used for lighting CFL, running TV, Charging my laptop, camera battery.Everything works fine.
Sorry for the late reply.Obviously you idea and planning is nice.But the rating you have selected is quite underrated.The module require 60w power, means if you supply is 5V, the current rating is minimum 12A.So it's better to use a SMPS.I hope it will be helpful for you.
Glad you like my work and voted for me.
Congratulations !Thanks for sharing the picture.
The product seller recommended to use 6.5V for better performance.But I think it will work without the Boost Converter.
I have sealed up completely just light gluing to fill the gap.The gasket option is best but I didn't have with the required size during the building.Thanks
Congrats !!!Nice build.
My speaker working with charm.You can't compare a expensive speaker with a cheap DIY speaker.

You are right.Using a battery holder is easiest way.But the holder was not in my stock during the project building.So I have to managed it by soldering.I will recommend for a holder.Thanks for the suggestion.
Yes, you can use it.I didn't have any stock, so I solder the terminal wires.
Thank you brother.
Glad you like it.The sound quality is really good.You can use a mini bread for wiring the components.
