[@dejanzdravkovic9010]

Nice idea,👍

[@generalawareness101]

I would be afraid of this because it lacks a real BMS. BMS modules are cheap that can handle up to 4S. TP4056 is for 1S for 2S, 3S, 4S use "4S 30A 14.8V Li-ion Lithium 18650 Battery BMS Packs PCB Protection Board Balance Integrated Circuits".

[@l0k048]

but this is 1S, there's only one group in series and many in parallel

[@mattivirta]

totally not good and safety, one tp4056 and 4 battery no newer do thats. one tp boarrd max one battery uses. you need safety charging board, BMS 4s board add this is want safety and good. and BMS no have regulater output need power step up/down usb board regulate and keep volt level alltime right if batterty go dry.

[@IAmZen_007]

Matti Virta Indeed, you need 1 TP4056 per battery. Don’t do this!

[@TheDIYGuy999]

The batteries are wired in parallel, so they always have the same voltage level. Of course, you can't do this, if your batteries are wired in series.

[@MagicSmoke11]

[@EurofighterTyphoon1976]

this is not a good method, in this way you just have to unbalance a cell and you risk ruining it. There must be 18650 TP4056 for each cell.

[@TheDIYGuy999]

They can't unbalance, because they are wired in parallel

[@DTeK]

That´s some real backup power !

[@TheDIYGuy999]

Yes, it's handy

[@nugienugraha2326]

This is very slow charging. Unless you need to use 4 charging modul

[@SonuSingh-hk4um]

Connect both cells in parallel after balancing them first. Don't connect batteries with more than 0.2V difference in parallel as this can risk fire and explosions

[@SonuSingh-hk4um]

Be sure the cells you are using are of the same make, model, capacity......etc

[@TheDIYGuy999]

Yes, what you said is important. Commercial power banks are doing the same BTW

[@sriganesh7047]

Is that safe to connect 4 lithium battery in one TP4056 module

[@fryatama]

Excuse me, I have a question why in this video use one tp4056 but I saw in another video use four tp4056 for 4 slot 18650 battery. Is there any difference using 1 or 4 tp4056 ? I will have a project with three 18560 batteries, tp4056 and solar panels. so I'm looking for a reference, thanks for video 👍

[@InsanSains]

He use 1 module to feed 4 batteries for fixed use as a solar charger. If you use 1 module for each battery the charge time will be faster, and you dont need worries about balance issue, different brand for each batteries.

[@asadost258]

How much time it will take to charge 4 batteries?

[@koluniok3409]

nice, but you should use one charging module and one output module for each 18650 cell. If not, you can damage the cells

[@cybrhckr]

is this true?

[@koluniok3409]

@@cybrhckr Yes. Think about it- you must control each cell separately. How do you want to achieve this using one simple charging module? The best solution is to use an BMS which controls more than one Li-ion

[@reecehudson5913]

Im really new to electronics but ive read a lot of people on reddit and forums saying its unsafe for a single charging board to be used on paralell 18650 batteries but i can see that you have done it with no issues. They said: ""You shouldn't put batteries in parallel, especially rechargeable batteries. They will never be "exactly equal" and one battery can discharge into the other which is not efficient and could potentially damage the batteries and maybe overheat and start a fire! "" ""You can put batteries in parallel if you add a diode on each battery to prevent reverse current, but you'll get a voltage-drop across the diode (0.7V for a regular silicon diode) and you'd have to bypass the diodes for charging."" Is this something to worry about as i want to do it and it looks like you have done it succesfully but i need it to be safe.

[@TheDIYGuy999]

Most commercial 18650 based power banks do exactly the same.

[@jordruss8621]

Its way more of a risk with different cells, when they are the same it will take alot longer but 1 will eventually drop below the rest and the cell will burn up when charging. Again its usually a case of replacing said cell and its good to go again

[@croydon21H]

The video is done in a near perfect risky model. Rotary tool to cut is totally unsafe.

[@andrepolhaar]

Great video, this will be very helpfull for me. You seem to know what you are doing so I would like to ask for your opinion. I’m thinking to use a setup like this to power portable Arduino projects for longer periods of time but I would prefer to cut off the load at a voltage of about 3V instead of 2.5V as used in the protection board. I’ve wondered why all the protection boards cut off at 2.5V instead of 2.9V like most batteries require but apparently that has to do with the voltage drop during high loads and cutting of at 2.5V makes sure the power doesn’t shut down during those temporary drops under loading. However I will not be using high loads, making the voltage drop under loading smaller and therefor the 2.5V cut off seems too low for my usage. I read that the voltage drop from 3.0V to 2.5V happens relative quickly and that the 18650 cell recovers to 2.8/2.9V almost immediately after the load is cut off at 2.5V but as my projects don’t need much power I am worried that the period in which the cell is between 3.0 and 2.5V will be too long and might damage the batteries. To get the load to cut off already at 3.0V I’m thinking to use the S9V11MACMA step-up/step-down voltage regulator (www.pololu.com/product/2868). It can step up the voltage to the level I need for my projects but, more importantly, it can also cut off the power when the voltage drops below a set level. Output - and cut-off voltage can be adjusted with potentiometers on the board to e.g. 5V and 3V respectively. The board would replace the step-up booster and should cut off the power before the TP4056 would. Do you think that will work as intended or will it introduce complications in combination with the TP4056? Also I wondered if it might be a good idea to add a glass fuse to each cell to isolate it in case of a cell failure for additional safety. Probably a bit of overkill as it is only a small pack, but the costs are minimal and the idea of burning my house down is worrying enough for me to consider putting them in. Obviously I would need to use 4 separate cell holders and parallel connect them after the fuses. Any thoughts on that? Maybe I’m just worrying too much.. :)
