Features of light catching

Yeah... What they won't write...
Despite the fact that both the choke and the tungsten / nichrome coil, when turned on in series with a mercury lamp, perform the function of a current limiter, these are different things. A choke is an inductor. And nichrome and tungsten coils of inductance actually do not have, these are resistors.

I will continue the thought: which is similar to running DRL through an electric tile (sometimes so drl is started for lack of a throttle)........
Another thing: has anyone tried to prick the DRV? I understand that in the outer cylinder is a tungsten spiral, which in direct contact with the atmosphere will burn out instantly.

About the price: "Quality costs money." Or another proverb on the subject: "A miser pays twice."
About the greatness of the chance to run into trouble: I think a well-established brand in the market simply tries not to get involved with dishonest suppliers of components for its products, so as not to hit the dirt with its face.

Fake brands!! This is the problem with lithium batteries!
Today I tried the battery from the makita 2ACH screwdriver. Pulled 1A approximately 1h40min.

Purely theoretically. Carefully split the bulb, find the spiral, break it off and solder an ordinary incandescent lamp in its place. Choose the lamp power according to the thickness of the tungsten spiral.

It is possible and so...... And sense where? And what kind of soldering to molybdenum (if of course in the DRV these conductors are made of it like in a classic light bulb)? And the heating? Ordinary solder will not work....... It's easier to take the DRL and run it in the usual way

On dx.com managed to buy it Trustfire 18650 decent quality of about 2Ah in reality at a current of 1A.

Panasonic TrustFire NCR18650 Rechargeable Battery 2900mAh.
Super batteries! Real 3achs! Expensive, but 100% worth it, not fake, most likely really made in Japan.

A battery pack like this arrived today.
http://www.ebay.com/itm/170937990572?ssPag...984.m1439.l2649
And in the description it says 8000 Ah, and on the one that came to me-9800

Check back in a few days in Pattaya

How can I build a 9 Ah dial out of them, at least?

Well, how many real Ac frequencies are there in your set?! I can't wait for my own!!

It is easy to assemble a 9Ah battery pack from such batteries: message 2702. Only here the cost will be high. You can collect anything you want. Just note that for 12V you need to take boxes for 3 batteries and the output will be slightly less (about 12V) .

I can't measure it yet, but I don't expect miracles
In any case, I will go with him and not with a lead-acid battery.

Well, at least I plugged in a light bulb, measured the current and waited a little while until it went out. Don't you really want to know how long you can count on fishing, or even whether you should take up space in your luggage?

Then I somehow remembered one subtlety that killed one expensive diode for me: some kind of microspore got on the surface of its silicone lens. As a result, this speck caused overheating and blackening of part of this silicone lens, so you should be more careful with the use of high-current leds and monitor the exceptional cleanliness of the surface! And it follows that they must be used necessarily covered with something from all sides!

Tomorrow, all tomorrow.

For reference (as I mentioned earlier). Today I opened the battery from an ASUS laptop. See: the 18650 format. Well, the point of contacting this (Samsung banks):

But the cost? what is the cost and number of ahs?
For 1.2 tr, I can buy 3ACH....at first glance, not so bad.

Buying 3Ah for 1200r is too much, one amp-hour goes for 400r in the case of Japanese batteries. I bought on dx 240r/Ah tested batteries (6up 2 batteries, i.e. 3 sets), which I wrote about earlier. I believe that I did not lose.

In total, I have so far purchased a stock of about 5 hours of fishing on lithium batteries, which is already more than excellent. I don't think I'll last much longer!

How much will give and NiMH, but it is not yet clear whether I will take them. If everything comes and works decently, then 2h will give me AA NiMH, about an hour will give makitovsky battery, if I'm still going to break it, pull it out and give a decent shape to the batteries from there.
By the way, can anyone understand such algorithms? There are no bolts, just break the plastic, but I don't want to...

And what is the capacity and price of the laptop battery? How do I charge it?

And what is the capacity and price of the laptop battery? How do I charge it?

Denis, I've only gutted my own so far. The capacity is not indicated on them, but this matter can be corrected in this way-as you can find out from the marking. I think it is sufficient if I have a regular 2.5 a/h smartphone: then the laptop should be more powerful (eats more). I just have the opportunity to get such batteries for free. And you can always come up with a zyaryadnik......
UPD I figured it out with them: I'm sure honest 3.6 v 2200 ma/h (according to the marking, the number 22 means 2200, and the voltage is standard for everyone) the only difference is that they are made "for soldering".
I'll repeat the link for these batteries: http://www.li-ion.ru/

I can only get Makit's PSUs from screwdrivers for free.... and what's good....they're heavy. You have your own specifics, very narrow. It's not cheap to buy one at retail.
In addition, good quality batteries were found for 7.7 ue per pair with free shipping and the same 2Ah. I don't see any point in overpaying.

3. I'll take a Chinese gadget to recharge my phone on the plane, and the rest is a suitcase.

Later, I will make an uninterruptible power supply for the modem from these batteries...

Roma, what's wrong?
These akki from screwdrivers are thrown away, because the screwdriver itself serves less than the battery, from here I can take it for myself. What's wrong/wrong with this? I don't understand...

It's the same with laptops. In a particular case, the hana of the matrix came and the person decided to throw it out (and quite often such "meat" gets). As a result, 6 units were acquired. batteries. And charging them is not a problem with an adjustable PSU with a comparator, which simply will not give the battery anything extra.

Well, then this is already BOO, with laptops this is understandable, I generally read that in Moscow they throw this out))
But with screwdrivers, I was even more surprised on the contrary - they buy new batteries, and they sell them everywhere, I myself bought that pair of 1.2 V 10Ah batteries on the market from the kit for screwdrivers

Well, then this is already BOO, with laptops this is understandable, I generally read that in Moscow they throw this out))

Well, used, not used, this role usually plays a small one-as the controller is usually covered (the control board that goes separately), and the batteries themselves remain quite functional.
By the way, they go in my opinion without built-in protection, so you need to take this into account when developing charging: advice for those who want to use such akki.

Roman, you should understand that for production it is more profitable and easier to throw out the broken consumable material and buy a new consumable, which is not the battery for the screwdriver, but the screwdriver itself, the charger and a couple of accumulators combined. For personal consumption, this principle is also acceptable, starting from a certain amount of income. And with some income, it is reasonable to buy replacement kits and play with a soldering iron. Don't you realize that time has a maximum price? Personal time and work time have the same high price!
For example, there is a 5tr screwdriver. You have to buy 3-5 pcs per month. PO with taxes of the employee who can perform their repairs, 23tr, deductions from the federal tax service of approx. 35% (and this is not all employee maintenance costs). Well, what is more profitable in your opinion? The problem seems simple....
Everything has its place, time, and application.

It's surreal...

Is the weather bad? What's the secret to your bad mood?

I lit the lamp an hour ago, they write on the Internet that the current in the lamp (Philips TL 8W Actinic BL tube) is 0.145 A. In theory, even if the typesetter that came to me does not fully meet the declared 9800 Ah, it will pull this lamp for a long time.

Well, we are waiting...

So, the lamp lit at 18: 30 began to burn intermittently ("it will go out, it will go out") at 01: 35...
Now let's see how much the standard charger will charge

So, the 8W lamp ate together with the PRA no more than 0.8 A from the battery (did you measure the current yourself?). The result is that the battery capacity is about 5Ah.

No, I didn't measure the current, I forgot to take a multimeter.

Who has dealt with gasoline or diesel power generators? Which brand is optimal for field work? So far, I have found such an option as the optimal combination of compactness, weight and power:

Maybe there is a better solution?

Isn't the power too low?
Although if this is a real 0.7 kW and not Chinese, then it may be very good.

I would not advise you to buy and advise you to buy such things yourself!
Where does it say exactly at what voltage the ampere-hours are indicated?? This is the most important parameter! It is not specified, so this ad is a direct fraud!
In this volume, it is really possible to cram the specified Ah, but only with the calculation of the voltage of 3.7 v! It is not a problem to recalculate all the others. Sunny hangs out there for the sake of beauty. I played a lot with a much better battery.
If something really cool and powerful lithium-ion was put in there, then such a PSU would be 0.5-1 mower of Baku. Lithium amp-hour is very expensive, high-quality and powerful lithium amp-hour is incredibly expensive!
Didn't you see yourself on your light bulb what the Chinese 10ahs are worth?! I've had enough...

Well, 8 hours of lamp burning and 12 hours of charging later with a weight of 400 grams. Basically, I'm fine with.

Tu Bianor, this brand has been sold in the metro for several years, the price for them is low, just buy and do not violate the rules of operation and the unit will last long enough,and just do not let it be used by third parties,the idyll will quickly end with an emergency failure and subsequent restoration of this unit..IMHO.

Well, 8 hours of lamp burning and 12 hours of charging later with a weight of 400 grams. Basically, it suits me.

But this is far from 10a/h. And it is not known how many charge/discharge cycles this case will withstand. I had a flashlight that was equipped with charging with two similar 3800 mAh batteries: six cycles approx. they also worked on Khan. Don't mess with Uncle HU's products at all.

So it can't yet........ And HU will write anything One of these days I will try to drive my laptop with a 5w handset (there is no more powerful PRA yet). I measure everything after the fact and unsubscribe here.

A long charge may not be due to a cool battery, but due to a poor-quality (weak) charger. And I have 3 different chargers for 18650 and each charges different time.
Everyone is faster charged by the Chinese dc-dc converter that I advised here in the topic, which is why I bought the second one. Moreover, I bought another charger for it with a high current (try it). He's really cool. Even the fact that it uses standard batteries, which can be found both better and worse.
In some cases, except for the iteration method, nothing gives a result....

By the way, the amount of ah is still changing (falling) when the current consumption increases...

Uncle Akio Toyoda has mastered everything for a long time, it is we who have not mastered the ways to force our superiors to share with us part of the funds obtained from the sale of minerals belonging to US, just as we have not mastered the methods and methods of obtaining a PO that provides not the limit of survival, but a life worthy of a Person. In the developed world, people can do this, so Uncle Akio works for them.
