which website do i use to check the status of an iphone?

casspersteve:
boss did u go to college?

Yes. My parents sent me to school.

But at final year of chem Engr. I left school because I knew the degree is not in line with what I stated I above.

Success is relative.
Financially
Business wise.
Family
Health
Life style

For me. One of my top most priority wasn't just money. But I wanted to have a business that worked independent of me. So I never sacrificed this dream even with different opportunities to make money

Cos this would afford me the time I needed to take care of health. Family and enjoy the sort of life style I desired. Even an opportunity to check and run other businesses.

When I was broke the strategy I used to pick ma self up was to look for a product that had a large market base yet little or nothing in cash or regulatory demand entry but then I spent all my time and knowledge to be better than anyone.

We always take health for granted. But I tell you money is zilch if there is no good health to enjoy it. So as a priority I do my checks more often even though I am just 32. Because I have a family history of diabetes and high bp.

Also because of my mode of business. I spend time with my loved ones a lot. My babe get tired of seeing me and my son we spend hours daily together. I see my father and brother daily. This as deeply enriched the quality of my lifestyle. I laugh from morning till night.

The next success I really crave for is to be able to run multiple businesses concurrently. have 2-3 vacations yearly. I pray in Good time it'll come to pass.

If I was to die today. I wouldn't regret my choices cos success to me is a balance of these things.

But chase the money with good strategy. Cos a lot of desires need cash.

Dapsyra is right. They are classified under IATA, DOT and IMO as class 9 Harzardous goods, UN3480 classification. Confirm the shipping mode and cost.

Batteries generally by air yes.. but I will inquire from my FF for sea. if there's any special classification now.

dapsyra:
@Damola1,

LifePO4 batteries are categorised as "Hazmat" for shipping purposes. This impact shipping cost adversely.

Please get a firm quotation for shipping before buying.

I ship by sea. not air.

Oshomo12:
@Demola1, state ur location so that any pro close to u will help u out once u have those batteries in place.

I am ikeja. Off oba akran. Right now. I need to buy or not buy. Should I buy?

Oshomo12:
Do a YouTube search on Lifepo4 BMS, also read about it. This is very important if you intend to use this battery chemistry. It's the best for now and also expensive too. So you cannot afford a mistake on them.

jazzman2:
@Damola1, you need to know exactly what you are doing with LifePO4 cells or like I said b4, they will turn very quickly to expensive bricks. Go through this discussion https://www.solarpaneltalk.com/forum/off-grid-solar/batteries-energy-storage/lithium-ion/2017-lifepo4-the-future-for-off-grid-battery-banks to get an idea what you are dealing with. Regards

I continue to appreciate your kind input.

A few pages of reading and the video:
https://www.youtube.com/watch?v=6i8i6h1LkBw

The charge efficiency of LiFePO4 is very high. Which is really very good for our epileptic power supply in this part of the world

The BMS prevents overcharge and overdischarge - there is some weak balancing in the pack to bring the voltages over time to even values.

A Controller has also a function to disconnect the load in case of battery discharge. Put low voltage sensor just to protect batteries.

Use a standard PWM charge controllers with LFP battery system

For example:

PWM charger adjusted at 14,8V;BMS system and low voltage sensor set to disconnect the inverter at 10V. because The low voltage sensor is VERY important to protect the batteries.. Even one time you go below 2.2v per cell the battery can go DEAD


-----------------------------------------

Point 1. this LiFePO4 is cheaper for me right now than the lead acid. if it's actually at 90% as stated. At 125. about: 65k excluding shipping and duty. so, maybe: 85kplus.
Point 2. I am a small business owner. And in most cases what I need is for an expert to setup the system, and for it to run independently. if there's any issue at any point, contact a pro to look at it... will this change for this system?
Point 3. i don't have a solar system yet. presently, we get at least: 14 hours of electricity at work, and I only need a battery to be there to backup for the remaining 10hours or so.

-------------------------------------

Really, from can't I get a pro to get this running without having to be directly involved in the technical aspect?

Yes. one needs to be careful not just with this but anything new. However, with the right technical expertise to manage it. then is that really a big deal?

DMerciful:
I recommend you go with d LiFeO4 batteries. They are the future with huge advantages. I am using one currently and loving it

-----------------
The seller stated:

These LiFePO4 need to be run with a BMS (Battery management system) . If you haven't worked with lithium cells then it would be better to use Lead Acid Deep Cycle Batteries which are more forgiving to accidental mistakes.

--------------
Me, I don't know anything about BMS. But do I know anything about inverter before? what we need is un interrupted power. so, am sure if need be , one can overcome it, is this something to worry about?

Normally, as long as I put my battery in a ventilated area. and make sure it works fine. Is there any other factor to work on? OR do I need to engage the services of a local professional? in installation and on going usage.

pranil:
Thanks, I checked from web -9 http://www.evlithium.com/CALB_Battery/42.html)
They are multipurpose for EV ( vehicle) and storage with very high rating - Similar Brand new cells on EVpower are 250 USD per piece

so it a good deal DAMOLA has found

But additional BMS is recommended - http://gwl-power.tumblr.com/tagged/SBM

they are rated as

Cycle Life 80DOD% ≥2000 times
Max.Charge Current ≤3CA

Max.Discharge Current Constant Current ≤4CA

Impulse Current ≤12CA

Standard charge/discharge current0.3CA

jazzman2:
To do the test, you basically hook up each cell to precision dc power supply through a coulomb or energy meter like the trimetric or victron energy meters. But before then, you will have to drain each cell to zero SOC state, which is at 2.5v resting voltage after 24hrs. Set the bench supply to constant current mode @ 0.5C rate. Set an over-voltage cutoff at 3.65V and allow it to charge up until the voltage reaches 3.65v and cuts off. The energy meter should be able to read off how much AH put into the cell. As a confirmation, modify the setup and discharge the cell through the energy meter to a load resistor to 2.5v after resetting the energy meter.

So, make I buy am ba?

cos, there's no way to test, and i am simply stuck. na 1M I wan throw on top 12 batteries. Make I no go put am on top brick as jazzman2 yarn.

the seller said:

The systems they come from have only done a few cycles, secondly I tests them through a few cycles to make sure there are no under performing cells.

Best regards

sharp guy

how can he repay back. did he work during that time for free? or he didn't eat. drink , go on vacation, family, or other expenses.

the supreme court judgement get k leg

Or

I will probably ask an installer to go check and give an appropriate feedback.

Thank you. will try to speak to the seller to go through this and give you a feedback.

jazzman2:
LifePO4 is the future of energy storage if the price continues to fall. It's advantages far outweigh the aging lead-acid technology. But you need to know what you are doing with them. The seller's claims are generally true for LifePO4.

Is there no way the seller can be asked to do a test and do a youtube upload as proof of efficiency? if so, which test specifically will I ask him to do and on which tool. since he's also an expert in solar business.

What I am going to do with them is basically to power my office as I stated originally. I just want to get 247, no generator dream to work out fine.

jazzman2:
You will have to invest in some specialised dc bench power supplies and coulomb counters to properly test, balance and characterise these cells b4 use. Some people may advocate the use of a battery management system (BMS), but very experienced users bottom-balance only and it's been working for them.

Appreciate you bro.

what you have asked is beyond me. Unless I hire a local to go do a local testing there, and not sure how to even find one.

Quick one: would it be worth it if I have to hire someone to go there and do a test. and what will I be looking for from the specialist actually. if actually it's: 90%. will it really be worth it?

second. what will you recommend overall considering my situation..am I over reacting with these phosphate versions or its the real deal like the guy proclaimed.

jazzman2:
LifePO4 cells are delicate and unless you know what you are doing, they can easily become expensive bricks very quickly. You have to do a very comprehensive capacity test to be sure you are not being sold bricks. Don't take the seller by face value. Can you share with us who your seller is? I am also interested in getting these cells too.

Thank you very much. The seller is UK based.

Actually here is the link:

And no way for me to test as I do not have the resources to. Is there anyway to make the seller verify his claim?

Post on this thread https://www.nairaland.com/390522/solar-energy-complement-fta .it is the number 1 solar thread

Thanks sir. Done.

This was recommended by one of my Ogas.

12MVR200 MONBAT. This is however, brand new. and will set me back: 130k each. But because it's: lead acid. I am tempted towards the used ones above;

Specifications:
• Nominal Voltage: 12V
• Terminal type: Front
• Grid alloy: Lead-Calcium-Tin alloy
• Plates: Flat Pasted
• Separators: AGM
• Active material: Very high purity lead
• Case and cover: FR ABS class V0
• Carrying Handles: Yes
• Terminal torque: 8 Nm

Good people. Great Nation. Good morning to all o. Please. abeg una, help me made decision:

Is this a recommended good buy?

I use a Magnum RD4024E inverter/charger in my office. and I have an offer for the following for: 80k each. 16units. We normally regularly have up to 12-14hours electricity daily. But I have also been advised to make sure the batteries don't get dead as that could make them die faster. so, after this purchase, I will probably be working on a solar panel backup. I run a 247 service. and primarily use the batteries for fans , computers, and nothing more. all acs are never on the inverter.

I am particularly interested in these because they are Lifepo4. and the seller confirmed the are still up to 90% good.

Very few cycles used, has more than 90% life left!

210 Ah Lithium Iron Phosphate Battery

Do you buy on eBay too?

Gucci irrelevant. Boy needs love of mum and dad. nothing less. He'll probably have pee on the gucci all day.

whats all this bullying.

@ op. Don't waste your time with these people. Any one who wants to buy it would have either known it or take their time to know it.

Owodiran1:
Bro English bro. I wrote brand new. I didn't write sealed brand new. Bro common sense. Brand new is different from sealed brand new. And how will i know what's inside if I don't open it. There is only few days to return according to return policy of where i bought it. So bro i have to unseal it to be sure nothing is wrong with. You guys love posting rubbish. But i ignore you guys. Today am ready for you. You wanna post rubbish and spoil person market abi. Bring it on. Am ready for you.

Improve and be educated. Ignorance maybe be bliss, but it is also a good reason to keep ones mouth shut!.. learn. if someone says something.. simple google. don't continue with your life like this... always shouting and arguing, and insulting.

New A brand-new, unused, unopened, undamaged item (including handmade items). See the seller's listing for full details.


Typically, open-box items are goods returned by customers, inspected by the retailer, found to be in working order, and re-sold at a discount, rather than returned to the manufacturer.Oct 1, 2008

http://www.consumerreports.org/cro/news/2008/10/open-box-electronics-items-another-shopping-option-to-consider/index.htm

You do not have to know what's inside if it's sealed. That's the manufacturer's responsibility. as a third party seller, once it's sealed. the end consumer is the only person with the right to open it. even if it's defective. And they cannot hold you liable, because the got it defective.

I bought this about 3 months ago, and this is exactly the same thing another seller posted: https://www.nairaland.com/3756336/original-beats-dre-headphones-sale#55952617

When I eventually bought it in computer village, the seller educated me.

If I want to give this as a gift to someone. It's opened. I know people who will reject it on such grounds.

New will be sealed. This is not. Open box

Na brain work!
