Current is NEVER TOO MUCH because the applicance draws what it needs.
It's Voltage that CAN BE TOO MUCH because it flows into the connected device.


in other words, if a phone's charger is rated 5-volts 2A , you would have no issue connecting it to a charger rated 5-volts 400A. BUT no make mistake connect am to charger of much higher Voltage.
wrong in this case.. most lead acid needs a charge current range of not more than 10%. pushing more than that will cause some damage...

All information is wrong..

Battery that does not have BMS cannot limit the charge current..

Also don't attempt to connect a 5V, 400A, 2000 Watts into phone. You will smoke the cable as well as the phone as there is a power limit the board can handle.

Obviously forgot that a hungry battery, would try to draw as much current as it needs.

yes I was correct that "the connected device draws the amount of current it needs", just that in this case, the battery would charge quicker, but it's life span reduced over time.

U could av snapped the inscription. Nonetheless. Reduce ur Ac charger to 20a as it's connected in series. Each battery will b charged at 20a. If all 4 are connected in parallel u wouldn't need to reduce the amp. Ur ac ac charger is a 48v 40a variant and not 12v 40a.
Thanks.

Even if they pull more, it would never be too large to cause a short term damage.
Reason why using a Tablet's charger to charge a small phone would quickly charge the phone within a shorter time, but in the long run, the health of that battery might be IMPACTED if the phone's circuitry isn't built to correct such anomality - say when the PHONE is not ORIGINAL.

Current, no be Voltage.

Take a laptop's charger for example - when the charger in use has current rating lower than recommended, the charger gets warm / hot during use. That's because that charger is struggling to supply the quantity of current the connected device (Laptop) is drawing.
Now if the difference between recommended current vs what the charger can provide is wide, the charger, NOT the LAPTOP would SPOIL.

Now when the Charger has a volatge much much lower thn whats recommened, the laptop won't power at all.

BUT if that same charger has voltage higher than what's recommeded, and the endurance ratio is exceeded, that laptop's circuitry would fry.

Again
Voltage FLOWs IN
CURRENT is DRAWN

Each phone has a sensing circuit to sense how much current the charger can supply but would limit the current it will take to what it can take.

If the current through the sensing circuit is too large it can cause it to blow and in the process take out other circuits around it.

Batteries don't have current limiter. Their internal resistance is too small to effectively limit current.

It's good to be convinced about what you know but when you see differing opinion always go back and revalidate your claim.

The information you passed isn't correct. Someone referencing only that your post would be greatly misled.

This thread is to share/learn experiences and what you say here is very important as it may help someone else positively or otherwise. Please have a open mind to correct what you had thought was the right thing.

1. No lithium cells comes with a BMS
2. A 5v with 400A source connected to a phone will sure blow it up as the current limiting diodes will fail at some point if not immediately
3. A lead acid Max charge current needs to set on the charger to avoid spoiling the battery
4. Lithium has a higher C rates with most of them being able to do 1C hence you have a lot of window to play around with subject to your installed BMS max

Ultimately as we say on stock thread, readers are adviced to apply due diligence on what they read here.

All the best

hmm

you guys still on this.

see I know what we say matters BUT , I'm yet to see where I got it wrong.

I also AGREE No One KNOWs it ALL



I used a phone as example, and we all knows it's difficult seeing a 5-volts, 400A phone charger BUT that was just to back up my talk that Current is drawn, while Voltage flows in.

It was a general talk not focusing on anything in particular, not even focusing on Lead Acid batteries the question was asked under.

So if you want to proove me wrong, please supply evidence (with notable Links), to back it up.

When I see something as RED, and GOD comes calling it WHITE, He has to really PROVE it else I no go gree. Not even because He's a God sef would make me blindly accept.

1. No lithium cells comes with a BMS: I disAgree with you here, both from personal experience, and from asking Aunty Google.com. I have built (not assemble/couple) a lot of things Sir. Also I have torn things apart right from my childHood days. Anyways, see Aunty google's response when asked https://www.google.com/search?q=do+lithium+cells+come+with+bms

2. A 5v with 400A source connected to a phone will sure blow it up as the current limiting diodes will fail at some point if not immediately: Rather than drop my opinion, which you obviously wouldn't accept, let me drop you a link. you're free to search more similar links https://www.physicsforums.com/threads/will-a-high-current-3-1a-destroy-smartphone-battery.789365/

3. A lead acid Max charge current needs to set on the charger to avoid spoiling the battery : Well don't want to say you're entirely RIGHT here. Because I know leadAcidBatteries have 3-stages of charge namely bulk, absorption, and float. and the current ain't constant in all these stages.

In battery charger, Current is being limited, else the Connected battery would try to draw as much current as it needs (Recall I said numerous times already that Current is DRAWN, while VOLTAGE flows in)

why not start your PRICing journey on JiJi . ng , then make a couple of calls. That way, when you're given astronomical PRICEs on nairaland, you would have idea on how to bargain with them.
Most prices I see here often makes me wonder the sort of humans we have become. it's even worse in that funny thread called "Clearance Sales ..."

I have blown up devices based on your assumptions.

I agree with you that there's a limiter capacity that if exceeded, the device might be destroyed.

The question now is what could cause this limiter capacity to be exceeded?

Certainly it can't be current because say a 2A limiter will do all it could to maintain a current 2A.

Could it be voltage? Yes!
Because the excess voltage will result to more power being dissipated by the limiter to maintain 2A current!

What could cause the excess voltage?

Case 1. The power source itself ( your phone charger )
Case 2. The battery being too low ( the limiter will disspate more power to maintain 2A for a battery that's at 3V, than when the battery gets to 4V )

So in assumption that your phone's limiter can handle Case 2 without any issue, and as long as the voltage of you charger never exceeds 5V, even if it's a 1000A source, nothing will happen to your phone.

Remember I said Most phones grin
