@ dollarnaira please what's the usefulness of the shunt?
I plan on getting without a shunt.

Without a shunt you can only measure voltage but not amperage. So if u're using for just voltage display then it's fine but if u need to measure capacity then you need a shunt.

Note that based on the amount of current u'll be passing through the meter, you should endeavor to get an adequately spec'ed one for the purpose. Cheers

@ceejay80s where are you brother? It's been awhile, hope you and yours are doing okay? Kind Regards

Ahyjo:
Please how genuine is this Valto guy ?

Very genuine, you can read up testimonies on this thread

HeavenlyBang:
Spotted on AliExpress.

260k for 4kwh, I think Will Prowse tested these cells a few years ago and while they're grade B you can pull about 95% rated capacity.

Just depends on if they're properly matched + BMS quality. Also if you even get your order

Please share your link, no one ships batteries for free on AE

BigDickProblems:
Bro, I don’t agree. Lai Lai.
15V to 16V is no longer a 12V system.

You can tell me that you will use a bulk converter and set it to maybe 12.6V or 12.8V depending on the battery type. But telling me that a 16V or 15V is a 12V system is false.

Bros calm down, most 12v inverter systems safely run BTW 10.5v - 15v, the sachet inverters do BTW 9.5v - 15v, while victron does BTW 9v - 17v and they're all 12v systems.

A quick question though,if you don't put them under 12v where would you fit it?

Jabez55:
What could cause a 12v 4s 70ah lithium battery pack not to charge to full capacity. The charging cut off at 15.8v

Which of the lithium chemistry, lithium ion or lithium iron phosphate

50p 3s in progress.

Looking good

You need understand rarely do I consult google and the likes to make a response.

Also i think the degrading is about 10 to over 50% based on temperature, among other things. In fact if the battery is fully charged sef, na another issue because it hates it

This guy calm down small, "you rarely consult google" and I remember a response to my post that you said I don't use the internet intelligently and now you claim not to use Google . Like I stated before u're a funny guy, smart but funny, unfortunately there are times us "intelligent" people need to chill.

I write most times not from google but from experience.

I for like see electric car wey de run on 75kwh of tubular battery storage

Abi oh, some arguments are just not worth the time to type it. The weight, the space, the maintenance period and the danger of spilling acid everywhere, yet some people hold on to an argument cos it's their forte.

Has anyone asked why the sudden resurgence of solar in Nigeria? Trust me it's not cos of Band A, it's because of the stability Lithium batteries has brought to installations. The fail rates for installations has drastically reduced, that's why anyone can claim to be an installer and can pass cos Lithium just works.

Installers know the shege pro max they suffered in the hands of lead acid batteries, some still dey igbobi after suffering from broken backs. Lolz

bassdow:
is that what you think ? That I am selective ?

Well me no get strength everytime to respond to some kind comments. You want me to give MATHs ba. Me dey speak mostly from experience, and Knowledge.

You need maths to tell you the viability of a Lithium battery decreases as it ages even while still on shelves. Keep waiting

Do grace me with a response on the shelf life of lithium battery is lead acid batteries. (Lithium when stored at BTW 50 -70% SOC or even while used will degrade to 80% in 10yrs) meaning you only lose 20% capacity in 10yrs, while lead acid will sulphate even while sitting on the shelf for only a year and if not attended to, will permanently damage in 2yrs if not desulphated.

bassdow:
Not everyOne got such time. Even me mostly come in here when bored. IT work no easy so when in a certain condition, and need clear my head, I find things to distract me and boom, I come to Nairaland looking for Arguments

Lolz, u're a funny guy. U definitely come looking for arguments, but only those you feel you can win, that's why you only answer based on sentiments and not on scientifically proven principles or deductions.

I asked for you to give ur maths on your comments on my earlier post am still waiting for your response.

Bruteality1:
Lol. Lithium maybe better but Tubular still serves

Let's get it straight, no one is disputing this fact that it won't serve, the fact all boils down to value for money even if it's small money.

Whether you use Keke,kurupe, bus, taxi, Uber, corolla or Gwagon, you must reach ur destination. Sha choose wisely. Cheers

bassdow:
...but there are MaintainNance Free Deep Cycle batteries na.

As for the so called war, I tell you say na person without personal experience go bother. Those wey Tubular or GEL / SLA / VRLA / AGM battery don serve, go hear all the praises rained on Lithium batteries, rush go buy am; hopefully they don't get disAppointed if they're Lucky or their useCase fits in.

Another set are FRESHERs (new Comers) to Solar world.

For the likes of Us wey don dey play with chemicals, from small, come still dey extract batteries from laptop batteries at less than age 18-years old dey build mini backUps, I wonder wetin those wey only got to know solar when it became popular thanks to APC regime wan tell us.

Personally, I decide when to go Tubular, and when to go SLA / GEL. Lithium has got it's place especially if size (Portability) & weight is a consideration - the more reason it's used in electric Cars / Bikes (weight factor) , Gadgets e.g Phones, PCs, etc (portability).

Mind you, Lead Acid batteries are much cheaper upfront than lithium based batteries. Similar reason a lot of people prefer buying Generator, than going Solar.
Lithium batteries can cost as much as 2 to 3 times more upFront.

What about Simplicity, and the fact it's been battle tested and rugged.


What about in places with much Heat ?

Abeg make I go chop. been battling with database data recovery for a new client since Sunday. To get client sweet, to collect Money sweet, but the work na die.

What's the price of an AGM/GEL from a reputable brand? Pls state and run a price comparism for us as against the above stated argument.

Secondly, a greater percentage of people SUGGESTING lithium are all coming from a lead acid background, some for more than 15 to 20yrs, built my first inverter setup In 2008/9.

As per ur the DIY route for lithium based batteries, I believe I have built more DIY packs to give me enough first hand experience and technical know how to advise any newbie on the right path to take.

When you chop finish we await ur writeup. Cheers

Tubular is between 250-270k for 220ah. It is not 100ah DOD but 176ah or roughly 2.1kwh

24v 2.5kwh lifepo4 is 600k.

So how's this math correct? Have u forgotten it takes 2pc of the 220ah to get 24v? Which in turn means that u're getting 2.1kwh (according) to ur maths at 540k (bear in mind that tubularor gel or any other lead acid offeringat this price point is substandard), while still according to ur maths, u're getting 2.5kwh for 600k, mind you this includes a smaller size, faster charging, longer battery life and of course no maintenance.

Bros no vex but try calm down small, let's not overflog this issue, the lithium vs lead acid battery comparison war ended almost 2yrs ago.

Let him that has teeth chew kolanut...... Cheers

dollarnaira:
My oga!
I hail oo.

Boss I greet you sir

Una well done oh, I originally didn't wat to comment but let me just drop this here. NOTE: This is purely my opinion.

The use or not of a BMS has been a long standing debate, however, let's state it that STANDARD PRACTICE recommends that one uses a BMS, over time the standard BMS has evolved and is no longer just an over/under voltage protection to an all-in-one monitoring system, nonetheless for individuals who have the technical and practical knowhow, they can do just fine without one especially in a small to medium size home use scenario; However for most medium to large scale installs, a BMS is a must, Also for beginners the addition of a BMS in your install is highly advised and almost non-negotiable.

In every situation sha we have exceptions and true live experiences have shown us that they work and work well for that matter, @Dollarnaira's case has been seen to work and i actually copied him on one of my builds, and truth be told it has worked flawlessly even though the bank is only used sparingly, but the fact remains that it works.

So like our elders say, he that has teeth let him eat kolanut

Congratulations Liverpool, they should great character this session. I'm truly happy for MO Salah it's been long overdue.

bassdow:
You mistaken. If only you could calm down and use the internet intelligently, you would confirm what I say.

Anyway sha, I am neither here to show Off, or act ITK.

The thread is mostly for adverts, sprinkled with a few DIY like talks hence no need me stressing ma sef.

Something wey even technician fit help you convert / add sef.

Me don close mouth for this topic abeg

Seems like having a civil interaction or reading through comments without bais is a hard call for your person but I won't stoop to your level. U provided links which didn't justify ur arguments, Thankfully @androblaze has done the honors, kudos also to @mrreed for doing the needful. You guys are much appreciated. Cheers

Mrreed:
There are inverters with dual voltages but the tech is still not mainstream.

Link to this please

bassdow:
As for examples, abeg try use Google.

either way, here's one https://me3energy.ng/victron-multiplus-inverter-12v-24v-48v-800w

Let me use google and find some more. But if you waka well for market, e dey or use Alibaba dem

Funny enough, a lot of so called SELLERs would tell you inverters don't work that way. Probably because their knowledge is limited

Please don't do this, you're confusing a lot of people with this narrative, most manufacturers include all voltage ranges in ads cos apart from the voltage and capacity differential every other component is the same, so they use the 12v/ 24v/ 36v/ 48v narrative at a stretch to explain the specs of the inverters, most of the top brands like victron have a wider voltage range but it's still an either/or.
Except you can show me a new tech that can do this (apart from solar charge controllers), I'll be inclined to disagree with your narrative. Cheers

Great development, nice one.....

lebete3000:
Hello bro how's your inverter fairing so far? Hope the batteries haven't gone pregnant?

Stanley08 now runs a mini grid system, so old things have passed away. But na wa for you oh, post since 2018 na him u still dey quote

Does the airtel unlimited per month still work? Is it still 20k even with the price increase happening with data currently? I'm thinking of switching cus right now I'm spending almost 20k a month and the data don't even last

Still available but it's now 30k...

Available....

Available....

How are they going for

220k

On ground and ready for pickup. Price slightly negotiable
