Because of battery tech changes
Historically, the popular battery that owned the market was the "carbon-zinc" cell... in size AAA, AA, C, or D. Think garden variety Ray-O-Vac. These are 1.5V - that's decided by the chemicals in the battery, chosen for safety and low cost.
Appliances typically use them in series strings of 2, 3, 4, 6 or 8 cells - ...
This won't work. You're asking a source of power (battery) that's designed to maybe supply 60 mW to supply 1 W.
End of story – you need a different power source, no circuit is able to create power (physics wouldn't allow that).
When you split a certain capacity battery into two separate (half size, half capacity) batteries, you might be able to have better thermal performance.
That means, it gives you more flexibility in where the batteries are located and that could potentially help in keeping the batteries cool(er) during charging.
During very fast charging (maximum current you ...
The answer to this question is just to look in the datasheet. You'll see that this cell is hopelessly wrong for what you want to do.
The Panasonic CR2032 states 225 mAh capacity and typical max. load current of 200 uA.
So it can't remotely supply the load current. Even if it could, it would be flat in 40 mins.
You must search for parts (battery) by their ...
I was wondering, would it be possible to stabilize the line and
provide the additional peak power say, by placing an accumulator
(battery + electronics) in the middle/in parallel?
In the end, the only practical and viable solution is to rewire the the AC feed cable to where you are operating the welder. Trying to interface a DC battery with a 220 volt AC ...
For the sake of estimate, let's assume the following:
Battery charge current = 0.1C = 0.1*60A = 6A max
Starter current is 200A x 3 seconds
When you start the car, you consume:
200A * 3s / 3600s = 0.17 Ah per start
Your estimated laptop charge is 120 Wh, or conservatively about 10 Ah per complete charge from the car battery.
So the total consumption to ...
Do not use LiFePo4 as a car battery, at or around freezing you will start doing permanent damage as the alternator tries to charge it. The solution is Lithium Titanate. you can purchase them from AliExpress (Alibaba is for businesses, they will sell it to you but use AliExpress first). Titanate can handle the extreme temperatures and has an insane charging/ ...
