Yeah... Kindly see the attached

This is more than impressive for a LA battery.Its contemporary usually have 700 cycles at 50% DOD

mcTrinity:
Hahaha.... Thanks for the review sir.

I've already gotten the data sheet from the supplier I'm getting the batteries from.

4 years is very okay and I believe it could do more years with proper management

I appreciate your feedback sir. Cheers

Index is a very good brand.Same quality as Fullriver!!!

zeestone99:
Why always Felicity.

Felicity still remains one of the fastest moving affordable and reliable brands.

They have a major dealer in Alaba that every other person buys from except you go to their office in Amuwo so there is actually slim chances of buying fake Felicity. So what the Alaba guys do is to supply lower capacity by tinkering with the packaging as wilmaria did!!

Valto:
@ customer it has already happened. please send the items back and get your refund , though i advise u let go, keep using it, if there is no bad performance issues. am saying this because looking at the price u bought them (90k for both) , brand new 250w panel is not less than 50k, talkless of felicity 60A mppt that is sold for 90 to 100k last price.

@willmaria14, we all know what u did. this is typical alaba style. u fraudulently supplied him, what his money can afford, which is very bad. why didn't u tell him that felicity 60A cc is actually sold for 90,000, and brand new 250w panel for 45 or 50k.
u should desist from this act, tell people the specific market price, who wan buy go still buy, regardless!

Baba,you could not have said it better!Guy should just continue using it as long as the charge controller is original just the lower capacity rating.Like you said,no way 90k could have gotten both.The used 250w Trina is like 25k so if the products are working fine ,just close eye and move on!!

And for wilmaria,I wont say anything more than what you have said.We should just try to be honest and sincere.

Please which delivery company handles items shipped via Singapore Post with RB..... tracking number.

I tracked my item and it says it is with the delivery company

Valto:
works directly from a 12v battery. very reliable and low energy consumption. price 24,000

Can this type also work with AC? I know some models can be used with AC power through and an adaptor

Valto:
there u have it. doesn't add up. i dont believe it is real capacity.

Well,if we agree then that the quoted prices for the affordable Lithium brands is not in tandem with the stated capacity,then I think it would be right to say then that the price gap between Lithium and AGM is still quite far.

Me I have jejely moved to tubular until Lithium becomes truly affordable and I have seen difference already when compared to SMF.At least the tubular will give better performance and longevity than AGM.

Valto:
they are selling 12v 150ah for 200k,which i dont think is achievable factoring in the real cost of grade A 150ah cells, good bms and casing.

Cloud energy's 12v 200ah is N240,500,the 24v 130ah is N332,000,48v150ah is N620k.

I can't really say their real capacity though

dejidotun2000:
Do you have first hand experience on this cloud energy 24V, 130AH.

I also came across Kartel 12V, 200AH.
I wonder if there real capacities are as stated.

I don't oo.Also in the market shopping for affordable Lithium

ojeysky:
Hmm.....more details below Sir



My apologies a good lifepo4 cells and a good lead acid is what I intend, but my own definition of good lifepo4 cells may be different from yours...see further....




You are right the above will be very laughable if that was what I said.




My definition of good lithium battery is on the cells, pylontech is very good but over 80% of that I attribute it that to packaging and the BMS. If I get similar packaging and BMS then apply precautions applied by pylontech on their BMS on my Eve cells I will get close to similar performance as pylontech.....so for me it's the content that matter most, get a good lithium cell and manage it as you wish.



If the capacity and quality is questionable then why use that as your measuring yardstick Sir? Brief maths, I just saw Valto post 8s/24v 280ah for 680k add another 100k for BMS and any other miscellaneous....780k. Note that those cells are good grade A cells....I hear there is Grade A+ but grade A is fine for my level

Lead acid capacity safe equivalent will be 500AH 24V
That is approximately 6 units of 160AH 12v batteries. A good lead acid should sell for 120k in naija of today. That is 720k. Yet you may still be running your lifepo4 after those lead acid might have packed up. Let's not include other advantages over LA such as weight and space consumption and high C rates



Felicity is not bad, what is bad in Felicity is that they are not being truthful with providing actual capacity of their cells.... otherwise the cells themselves are not bad.

You are right.The cost of good LA is almost same as Lithium.The best LA cannot give you more than 700 cycles @50% DOD while the basic Lithium will still give 2000 cycles @ 80% DOD,worst case scenario. Many companies which are traditionally LA manufacturers are gradually producing Lithium as well because they know that is the future.I am aware that even the sole representative of Index batteries in Nigeria is already working on launching its brand of Lithium.I also know a company,Cloud Energy that is already selling its brand of 12v 200ah and 24v130ah Lithium for fairly good price ( although their Lithium is just basic,no meter and no monitoring capacity).

numericalguy:
Thanks so much for your reply.

Please how do I match the float and bulk voltage spec of the batteries. Will I be using a load balancer for that?

Also, when I go lithium (I'm seriously considering that) will I need to change my inverter too? Someone once told me that lithium battery inverters are different from lead acid AGM inverters. I currently use Luminous 24v/1.5kva Inverter.

Thanks

Best you change the inverter.This inverter charges AGM to float at 13.6v while LIFEPO4 charges fully at 14.6v. By the way, how come this inverter has not collapsed with the capacity of batteries you are using.It means the inverter will be working almost 24hoyrs to charge 12 of those 2v batteries!!!

Thank you @Omotoda

I previously included pictures with posts I made. Its okay if I add pictures on every ad post?

Nicely built!! Keep it up!!!

I think the appropriate thing to do as others in this line of business have done is to post your price for different capacities as well as pictures.

You will create more interest and I stand to be corrected,but I think it was agreed on this platform some pages back that sellers MUST post pics of their items as well as price or at the least provide detailed information on item on sale e.g

"I could post that I have 24 units of fairly used Monbat 12v 200ah batteries for sale at N50k each.Batteries are used off grid but are connected to solar ".

I have not posted pictures but I've given a fair and concise information on item on sale.

en0uwem:
Yes, I'm very close to Oba Palace. I'll send you a message in the morning.

I don't really know if the installer is competent with setting up lithium battery installations cus I'm beginning to doubt it. I think the installer is only good with lead acid battery installations.

My brother,just let another competent person have a look and do a proper,tidy and neat connection. No professional installer will do this kind of job.He even joined a live wire with black tape mid way.How nah !

You have spent good money in this Buhari economy to have this kind of annoying set up!!!

omotoda:
To start with,we need to know the arrangement of the solar panels.From the schematic layout, your charge controller is 70 amp with max VOC 150v.I am quite certain that us grossly inadequate to cater for the input from you panels so some energy us going to be wasted.I don't what the Voc of each 350 watts panel.is but my guess is it will be close to 48v.

Which means you cannot have more than 4 connected in series.

My advice is this.Get a qualified solar engineer to look at the PV arrangement. I would advice you get another charge controller and separate the panels cos you are charging two batteries connected in parallel.

The arrangement should be 3s2p for each set up going into into each of the charge controllers and ultimately to the batteries.

If you had sought advice earlier, for this huge set up it is better you buy an hybrid inverter capable of taking up to VOC of 500v

You should subsequently see an improvement but ultimately you need to still increase your panel size.Total of 4200 watts is not sufficient to charge 2 of those 48v batteries when you consider losses as well.

As usual,the experts will still give their take!!!

And may I add,please change your installer.For this investment you.put up,the installation is untidy and doesn't show someone who knows his onions.He can't trunk cables,wires flying up and down.

en0uwem:
Good day everyone.
This is the solar system that was setup for my store. It's been about a month now since it was setup.
The problem with this system is that harvesting and charging is very poor. It barely charges well. And I am using it off grid - I only charge with the solar panels.

The charging is slow and if it continues this way, I fear the battery won't last as I hardly get a full charge. It's always one or two bars charging on very sunny days.

Please what should I do?

Hello bros.Any report from.your test so far? Let us know if Full river is still 'Fillriver'

eleojo23:
Hello everyone. Been a while.

Please how does one achieve low voltage disconnect (50% DOD) with an inverter that doesnt have it built-in? Is there any good external device for that? I saw something like that on AliExpress but the circuits are so small I wonder if they are practical.

From.my amateur knowledge,look for a charge controller,the typical PMW should do.Connect it to the battery and set the charge controller LVD to the desired voltage equivalent to 50% DOD.I think that should work.The charge controller will cut off load supply at the set voltage.The experts are here to advise professionally

Hi guys,

Some Canada made and used 220w panels available for a steal price of #40k / unit price.

Limited quantity left.

Bulk purchase carries some discount however...

No contact details.

odimbannamdi:
The 200ah costs 150,000, while the 220ah costs 230,000 or so. I asked them why the 220ah is sooo expensive, they said its a "special kind of battery". Make I manage this one jare.

Never knew full river has 220ah.What kind of special battery is that? That is way ridiculous for AGM battery.It's better to add funds and kuku buy lifepo4

Good evening Gurus in the house,

I seriously need your help. I have 12 units of 2V/600AH Shoto battery on a 24V system. Last night the inverter went off shortly after NEPA went of.
So this morning, I recorded the following readings on each of the batteries as shown in the pictures below.

Pls, you guys should have a look at the readings to tell me what to do as the readings on battery number 10 is abnormal

Just go and buy a single 2v battery of similar capacity of same lot.

That is one of the advantages of 2v cells.You can change bad batteries without condemning the whole lot!!

ceaser:
Bàbá, read the messages. Dude dey here already. I've gotten 5 different packs of different capacities from him till date. He even replaced for free one that the battery post terminals got damaged in transit.

One thing though, is that na pay before delivery and you'll most likely be responsible for the payment for shipping. But he will deliver it. Usually within a week of concluding payment, item gets to Ondo/Ekiti, in most of my dealings with him.



If your inverter has so far served you well, is rugged, big, strong and reliable, you might wanna keep it. It is something worth keeping. And it does not prevent you from acquiring LFP to use with it.

The only change you require is to do away with the in-built AC charger of the inverter and use an external Lithium charger hooked to the battery instead. Of course if you also have solar panels and CC, that makes the job of charging easier.

I have solar. 4 units of Felicity 260 watts panel hooked with 60amp PowMr CC

I better start putting up my Luminous inverter for sale.The only reason I haven't gone Lithium is because of my inverters. The price sure makes sense when you compare it with Lead Acid batteries that will give you just 50% DOD.Full river battery as at my last check with the sole importer in Nigeria about 3 weeks ago was #155k for 200ah.So technically ,Lithium is better cost wise in the long run.

I have a 12v 1.5 kva Icellpower inverterwith adjustable settings lying fallow in my store.Does anyone know if this inverter can work with Lithium? If not what affordable and durable options are available?

justcallmenuel:
Nah, it’s the power button sir.

A cleaere picture will be better.You always post more than one pics

edryz:
Sometimes, even national grid used to exceed 50 Hz, say 50.2/50.3.

What if its Frequency is 50Hz n yet does not still charge on generator. What could be the reason sir?

What is the capacity/rating of your inverter and generator?

NiyiOmoIyunade:
I have 12units of 1 year used ET Solar 360w monocrystalline panels for sale at 55k each

Anyone interested in group buy?I am interested in 4 units

edryz:
Hello experts in the house.

Please what could be the problem if an inverter stops charging with generator but charges when connected to national grid

Check the frequency of the generator. Inverters will charge at 50Hz

Thank you

bigbamo:
I need clarity on something please.
I don't mind if you can help me with answers. I have a solar system of Genus 1KvA inverter, 1 230aH/12V Genus Tall Tubular Battery, 4 × 180W Solar Panels and a 60A PWM Solar Charge Controller
The Solar Charge Controller got burnt
That's another story though

Prior to it getting burnt, I inquired from the installer about upgrading the Solar System to accommodate a 1HP Air Condition (Inverter type) and a 250 Litres Deep Freezer

He then told me I would need to buy a 2KVA Inverter, 1 More Battery, 3 More Solar Panels (375W - I suggested that to him though) and I would have to buy another Charge Controller in addition to the one I had (which got burnt presently)

So now that the Charge Controller is burnt, I looked up Luminous Cruze 4KvA Inverter and I think I like it

How many Solar Panels can I use in addition to the ones I have?

Can't I use one charge controllers for everything?

How many batteries will I buy?

Firstly, forget the idea of buying Luminous Cruze 4kva.I am very sure for the price of the Luminous inverter you will get a decent 3.5/5kva Hybrid Inverter that has better charging capability and efficiency. Then ensure you use minimum 4 200ah batteries. If you can afford LiFePo4, better.Solar panels will have to be minimum 10pcs of 280 watts.

I leave the gurus to add and subtract as necessary!
