Please o, how do i track my goods in this similar manner, epp me.

You just check any tracking site, I sometimes use https://www.aftership.com/couriers/4px

Anyways got my goods yesterday.

Lavisha:
Hungerbad is dead?

cbngov01:
hungerbad don ?

jidxin:
. Is hungerbad dead

Swagahyk:
I'm socked just knowing now...I still remember that moniker...'HungerBAD'. rest on

QuickStandard:
Is the person with the username: "Hungerbad" dead?

Karmaisme:
Hungerbad don die?

aimuan:
hungerbad rest on?is he dead?

12345baba:
hungerbad done die?

Pacesetter123:
Ohhhh,my heart felt sympathy.No wonder I av not been seeing his post again...ooo!

Well, it appears most missed the thread done in honour of this great nairalander. Here it is for some of those that missed it: https://www.nairaland.com/5204822/popular-nairalander-hungerbad-dies-age

sure but if a Gokada can take me to and fro, why disturb an uber?

Go for it then.

It is not a blood test as many of us may have thought. It is a swab stick that is placed in the person's throat or nostrils.

There are rumours that some of these swab sticks are contaminated with the coronavirus. We do not know whether these allegations are true, but we need to be careful.

The method of using swab sticks from the coronavirus testing kits should be suspended.

We shouldn't be quick to spread conspiracy theories, let's assume the test kits are contaminated. How long do you think it stayed in transit for it to come all the way from China to Nigeria? How long do you think it stayed in Nigeria before use? How long again does the virus stay outside before it dies? Do you think the virus have an infinite life outside of a host body?

BetaTechnicians:
So if the pwm has editable voltage, it'll work, yes?

If your controller's output voltage matches that of your battery's specified charging voltage, then you are good. Irrespective of whether it has the feature where one can change the output voltage or not.
But as you already know you can't beat the efficiency of an MPPT with a PWM of same make.

intergral:
please which tracking website are you using?

I used this one: https://www.aftership.com/couriers/4px

jboixxx:
Tell me more. How long did it take to get the refund for that?

Didn't take long. Just under a month.

jboixxx:
Customs are security agents, so, they're exempted and aside that, they're essential service providers at the port. Without them, nothing enters/passes the port of 9ja.

I hope your package will not come with NCS invoice with this mention of customs on your tracking page!

Not that bothered. If they like let 'em do that. If bill is much I can always abandon goods. Done that before and it worked. They returned it

sawdickwest:
hello my profile please I need help on this matter

am also trying to report a person in GTBank, I invested 100k with him last month and promising a returns of 150k plus interest within 2weeks, but he his telling me that he has a problem that he is unable to pay me my money but keep on posting me, I know him online more than 4 years, although we have transact 20k biz and said it went wrong and refunded me but it takes longer, He said he is into Sport trading and other business but am having second thoughts that he is trying to play funny with me

I have history of our chats on WhatsApp , screenshot of my transfer via mobile app

Truth is, if anyone has a business that can pay back that much, they'll approach a bank and get a loan that won't require 50% interest! You got scammed by a con man. Con is short for confidence. Dude paid back that 20k because he has eye for a bigger pay day. If I'm you I'll just lick my wounds and move on. You can try to block his account. But that's a long process, banks are usually very unwilling to block an account if there is no solid evidence that a fraud has been committed by said account holder with order from a court saying so.

I thought these guys, customs, have closed, who the heck just cleared my goods

hoctre20:
good day people, im About ordering an item on aliexpress, but on the sellers page it's showing only one order with no review, please I hope it not scammer,, as it the cheapest, though it's my first time Using aliexpress.

It's always good to buy from a seller with good reviews, sometimes cheap may not be a good thing.

This is inspirational.....but its gonna cost some good bar, as in damn real good bar.

If I have this, I'll never use public utility ever again.

BetaTechnicians:
ojeysky, ceasar and other lifepo4 users, how would you advise using a pwm cc to charge a lifepo4 battery?

To add to what has been said, you are better off with an MPPT SCC as most of it are customisable. You can change the voltage at which your battery charges, a feature which I doubt you'd get with most PWM.

My only question is....would an 850va luminous hybrid inverter be able to handle its startup surge.

The bot must really not like you. I post links here all the time

ameh99:
DOD simply means depth of discharge


While lifepo4 has around 85 to 100%
Lead acid has just around 50% or even less

Meaning you can drain up 90 to 100% of your lifepo4 batteries without harming them

But but can't drain above 50% in lead acid

Here is a perfect example;


Let's say you have a 100ah lead acid battery which are usually with 50% DOD

Meaning the actual capacity utilize is just
50ah

And if it is lifepo4 with about 90% DOD
Then a 100ah lifepo4 can give you 90ah capacity safely

Sorry I'm still a bit confused here, are the batteries not brand new? Like I said in my previous statement I know what DOD means. What I'm confused is the 91.3% DOD you added in the specs, are these batteries fairly used? I'm just a lil confused on that. Still is.

ceaser:
Please house.

System is 12volt inverter and battery. Charged by 2 pcs SCC units 60amps MPPT (same product) connected in parallel. One is fully maxed out at 6 pcs 150 watts panel connected in 2s3p. The second SCC receives input from a 2 pcs 150 watts panel in 2s config, planned to be maxed out like the counterpart at a later date. Batteries are 2 units 12v 120ah LFP connected in parallel.

On a good day, as much as 50 amps comes from the fully maxed SCC and 18 amps from the second SCC.

Wires leading from SCC common terminals to the battery is 10mm copper, about one yard each.

What I am not comfortable with is that the 10mm wire gets slightly warm when max current (as written above) is flowing from the SCC. And with the plan to still max out the output in the second SCC, to bring the total amp going into the batteries to around 110amps, I am a little bit worried that the wire may get unsafely hotter.

Should I be comfortable with the 10mm handling that anticipated amp or would you suggest something else?

Thanks.

That's why we love lithium, see high amperage dey flow like water. You can upgrade to 16mm² cable to prevent the cable insulation from thermal derating.

Tnycee:
Has anyone ever experience this fault on Fangpusun flexmax 80/150.

The unit goes into sleeping mode and doesn't wake up even after a reset.

Unit is about 4months old, connected to 8unit 300w Canadian solar panels (2×4 configuration)

My friend had this issue, this @ efuro's advice helped him fix the issue

Pasword is set at 141

Go to Advance menu of your flexmax
MPPT Mode to U-pick from Auto Track (if you are using inverter with nepa change nonGT to GT
From experience set Park MPPT to 77%
Mpp Range Limit as 1/2 (half from FULL) and VOC to 99%

That is all, this should resolve your snoozing problem.

ameh99:
Makes are

Eve Billion and CATL respectively

They are one amongst the best lithium iron phosphate battery Maker's in the world

The 105ah comes with a barcode that holds every necessary info

Here are the parameters of cells

105ah, 3.2v nominal per cell

3.6v fully charged

91.3% DOD (depth of discharge)

1C charge current and 3C discharge current

And Above 3,000 cycle charge/discharge

Wow, thanks for the detailed reply. I'm loving the specs. I'm a little confused on the DOD you put there. What does it mean? I know what DOD means, I don't just understand what the 91.3% DOD means here, or is it the DOD where you get the 3000 cycles?

Ok

ojeysky:
I don't think the behaviour should be different even if charged with utility. When a battery is full, such as my Lifepo4 the charge current drops to zero

I wanted to add "if inverter is on load" before the first sentence.

NiyiOmoIyunade:
I am not aware of this phenomenon you have described where current fluctuates between zero and a value o. I guess it depends on the engineering specs of the charger you are using.

The chargers I have access to all output a steady current - even the solar chargers increase/reduce current smoothly and tend to hold steady regardless of the stage of battery charging.

It happens only on solar. Goes to zero or near zero on most inverters and maintains that.

NiyiOmoIyunade:
While on solar, the current passing through the cables may not be zero especially if there are house loads running. Even without loads, whether running Mains passthrough or on solar, a good charger will still put out some very low amps (trickle charge) while the battery is full and in float - this kind of charge helps offset the internal self discharge of the battery.

A sure way to know if your battery is full is coulomb counting such as you do with a battery monitor like Victron or Fangpusun or Bogart - you basically measure the net amps in and/or out and then declare the battery full when sufficient amps have gone into the battery to replace what was used (various parameters need to be met to satisfy the battery full criteria)

A quick and dirty way is to use the battery voltage while charging as an indicator of state of charge - if your battery hits absorb and stays there for a preset time, you can declare the battery full for all practical purposes especially if you see the current drop sharply to a level called 'tail current'.

JaySterling:
How will I know that my battery is fully charged by the Solar panels

True, but they'll moments of zero and then some current, equivalent to the load on the inverter, and zero again. It'll alternate, that just means the battery is full.

ai499226:
Yes. Seconded.

Cool

Interesting, what is the make of this lifepo4? Can one see the spec sheet detailing maximum charge and discharge rate, number of cycles, etc?

mmars:
Guys xup, my 60 days buyer protection is almost over but as a result of this po lock down i am.not sure if i will get it. When the 60day buyer protection is over and post office is still on lock down should i open dispute? if not what else can i do?

You still have 15 days buyer protection on your side at end of 60-day protection. You can use that, or ask seller to extend purchase protection which I'm sure seller will gladly do.

JaySterling:
Hey guys, I’m new to this

How will I know when my inverter battery is full?

I charge with solar panels and Nepa too.

A sure way to know is to either to buy a clamp meter and measure the current flowing into the battery, if the current is zero on the meter, when there is NEPA or solar, the battery is full.

www.nairaland.com/attachments/11278778_images7_jpeg_jpegc250b88d3a108a1e74e6c9bf7bb78252

Or if your inverter has an LCD or LED display that shows the state of charge when the battery is full.

Pls observe covid related safety precautions oh... Use ppe with these foreign items. Bless you sir

He's more at risk from his fellow man than foreign items that had stayed days in transit with coronavirus, if any, long dead.

ojeysky:
I don't think 4x12v 60A will be 240, it will be 120A 24v

Cool. Image was pulled off internet, interested in showing him how to connect in parallel. Didn't even bother to see if the math in image is correct as it is irrelevant to what I'm trying to show him.

JaySterling:
my inverter is a 24V 2.3kva microtek inverter

Recently installed this week with 2 batteries 12V each

But I wanna add 2 more batteries for more backup time.

Can four batteries work on it, because each battery is 12V and times four is 48V

Yes, connect in parallel
