Brilliant! A proper regulator, modified calculations....A simple if not rudementary guide for energy cells. Good work!
Bros and sis don't make this it could be dangerous because most 18560 batteries are not protected. I made this in a time that I was 12 and didn't understand much about the dangers of li ions. Hope nobody got hurt. Go search for another tutorial, this is no good.
I'll try to do it.
Rechargeable (homemade) Power Bank (super Easy)
And how to find 5 V voltage regulator at home
How to make power bank for 4000 milliampere battery
its not in series bro look at first
I think something's will go wrong, as you are connecting cells in series so its voltage will increase current will be same i.e. capacity is 2200mA but rate of charge flow will be triple. I think you have to connect cells in parallel to improve capacity to 6600 mA and voltage will be acceptable to charge mobiles..
Series ups the voltage, not capacity.Parallel ups the capacity, not voltage.
Can we use a zinner diode to avoid voltage fluctuations?
What is approx charging time of whole setup....and confrm i can recharge it through rca female usb port?
And how to recharge ...and with how much voltahe as the rca is direcltly connected to batteries?
6600mAh? The batteries are connected in series and you get 11.1v the capacity should be 2200mAh... Connect them in parallel and you get your 6600mA but only as 3.7v.You can not have both worlds...
You WILL need a board to handle the power input. In fact, I'm pulling one out of a defunct power bank, removing the need for such things.However, DO NOT TRY THIS. I cannot stress this enough: it can be dangerous, even with the RCA port. If the batteries are not protected, or if the voltage is not properly regulated, bad things happen.
Here. Hopefully, this ought to clarify things at least a little.DC in can also be a solar panel.
The capacity of an individual li-on of this type and size is more or less 2200mAh. In a series of three, the total comes out to around 6600mAh.
More or less 6600mAh.
What its capacity ?
