Battery advice for my solar system?

Which 5 volt 30 A connection is this power supply? I tied black with purple cable. 3 cells can be charged.

connecting to the 4 wire molex leads, the black are negative/ground, the Red wire is +5V, and the Yellow wire is +12V. Those are the wires you really should use as they are heavier than the others.

Also, you have to power on the unit by connecting the green wire with black (they are right next to each other) on the ATX connection. You may need to look it up if you don't have a green wire and look at the pin # instead.

thank you. ATX the link to say I did not like. trying to. 15 battery at the same time being charged. an old fan with cool. cells 10 pcs more 0 Volt, and the trash went.

view all charge I will., and one by one number will give. a table and save the discharge capacity that I will. each cell how to, and that the quality of registration will.

Can't understand what you're translating... 
Btw, in the market you can get the TP4056 with the 18650 holder together... meaning you do not need to wired up like what you're doing now... Just connect to USB will do... simple

Everything is alright Smile turkish contains very meaningful words. That's why the cycle is sometimes nonsense. I charge batteries. I will discharge and write the capacities. I did not see the photo on the link. I brought the tp4056 china. I can not find everything in Turkey. I pay a lot of cargo fees to other countries. So I have to make up with that.

The best DIY is to use what you have. No need to buy the chargers and holders combined as together they cost more than buying the 4-cell holder and 4 TP's.
And, reguardless of which setup he is using, he still needs to power the unit. If he uses all the USB connections, that's a lot of cables he either has to cut the ends off of, or buy USB hubs to power everything.
Using a computer PSU you get stable power, full amps available, and recycled from old parts.

Below are 3 images you may need to wire up the PSU. The Green wire I was referring to earlier is Pin 14 (shown in the middle image) You connect that directly to ground (Any of the black wires) and the PSU should power on. "IF" you need to put a load on it so it'll power up, you will need to use the resistor method shown in 1st and 3rd images. You could even use an LED with a resistor as a load and it'll show you when it's powered on.

The 1st & 2nd images also shows the negative rails if you need/want those. Remember, you don't want to plug negative voltage (-12v, -5v, -3.3v) to a normal unit. You could fry the components.

Thank you for the information. I made connections as you say. The TPs are currently working. I charged 45 batteries in 2 days. I need to find the old battery. There are 200 batteries. I need to get 640 pieces.

I bought this device for battery charging and testing.

Liitokala Lii500

It's about $ 15 cheaper than opus. We can call it the half price of the opus device.

I will test the ready batteries. I'm trying to find old batteries.

I bought a battery holder.

FIY. That charger can only test discharge at 0.5A. Thats the big difference compare to the Opus that kind of does 1A.

This is not very decisive for me. I will have a lot of time to do what I want Smile. Thanks for reminding me.
