What am I missing here how does the positive connect in aa mode

1yr later and theyre sold on amazon like hotcakes because people HATE buying batteries. 4 for 10$? No 3 dollar usb-attery lol

I have done the same for 240W but it's not working. It's giving only 2v after connecting with power supply

Uff itni mehnat .....

It works been using it past year lmaoo

Just ignore the explosion and chimical burn

U can buy these

Capacitor. With faith in the word warnings of God our Father we can move mountains to block divert Noah's SE to NW tidal Tsunamis to come.

Nice

Blud almost made himself go kaboom💀💀💀💀

They actually sell batteries like this, but if you so need to do this than carry on.

How much cost for repair this only

Or I could just get a USB charger.

WOWWWW

I have a pair of AA rechargeable that are 10 years old and last for months.

Who is actually gonna make this?

How to make something incredibly hard look easy😊

Very beautiful

People really tryna dropship these nowadays 💀

how much is the super capasitor price there?

Don't think of lithium batteries as a joke its verry dangerous to plug and play plus unwilling without proper equipment and a safety model.. Better be aware using proper lithium ion batteries with BMS

Instead of it coming at the same amount, electronic lovers can try with safety equipment and proper knowledge of what are you trying to make sure that.

This is like those other videos where they ruin a wrench, wood saw and a grinder just to make something that scribes circles yet you see a speed square in their tool pouch!

Capacitor + - 극성 없나요? 그리고 Capacitor 는 어떤 역할 하나요?

The problem with this type of spot welder, you can very easily blow a hole thru the case of the battery (neg. side) and cause a leak. I did and had to take the cell to Hazardous Waste for disposal.

Yea. But I don't have these equipments 😂😂

I'd rather just buy a new pack of 20 for 4.99 thank you

Just no, you shouldn't do this period, I have a B.S. in electronic engineering I know batteries very well and I wouldn't do this.

hi, if I make a dc power supply directly taken from the 220vac power outlet (using a bridge diode and a capacitor and supposed to become about 300 vdc), what needs to be modified? the size of copper and the numbers of the copper wires turning? and what else? please advise me, thanks.

Thanks for helping me in my physics project

This is not an idea this is an art

Is good, I only lost two of my fingers, but it worked.

Instructions unclear! I rode my bike in my fishtank and put wings on the bathtub, but couldnt reproduce the result! Please clarify!

Aku kira dia meminumnya sampai habis

make a battery got cancer in the process

Until the battery is out of power. Then you start all over again.

Bruh... if i could do this i wouldn't be worried about buying batteries... id just sit around watching tv making weird usb devices all day and selling them online.

Não era mais fácil comprar não

Hello, I want to make this montage myself. Please give me the diagram too

Can I use irfp250n or not?

1200 watts... no creo. La fuente y el dimensionado de los componentes no da para esa potencia. Es triste ver cómo manipulan la información.

Wasted time reachable brother
