Reliable Electric

Dubai Miracle Garden with over 50 million flowers wow

I want to vist this place next year

valemtech:
we have a service centre boss at ikeja ,u should have just asked, 14 ladipo kuku Street ikeja off Allen avenue Ikeja Lagos

Not everybody is in Lagos, must of your buyers are still outside Lagos

Reason for the request to put up ur screen replacement on jumia so those of us outside Lagos can buy and look for a phone repairer in our location to fix it

I don't stay or live in Lagos and my device screen is broken

bodeface i likely don't know the technical term to use, you may want to watch this, it will help a bit in clarify that of the premium brand and other brands

I had to check up the 2 battery u listed Battleborn and ruixu omo Lead Acid fall our hand ohhhh

See lithium dey blaze

Lead acid was able to pish to 67Ah why lifepo4 dey do 93Ah and 95Ah

Please RE House,;
Good morning!
I am trying to upgrade my solar installation and I need advise from experienced members, installers and seller in house.
I currently has 4 X 200Ah AGM battery, which have served very well, I am undecided on either going for 8 X 200Ah or I should port to Lithium Battery (LiFePO4)
I know LiFePO4 is better in performance, you can derive more juice from it compare to AGM, I know all that stuff.
But more on value for money,
1. Is these LiFePO4 reliable
2. What's the failure rate like, in AGM battery bank you can replace a failed single unit (though not advised)
3. What's user experience, any user experience?
4. What are good model / manufacturer to consider for value for money
5. What do you advise; buy the AGM or buy the LiFeP04

Thanks

1- very reliable

2- the failure rate is very unlikely, yeah even if any cell pack is bad u can replace it but most times all there need is for u to balance ur battery pack

3- there are user experience here but u can check some of my past posts as at last week to see some YouTube reviews

4- there are premium brands as well as brands that are not too know but stlll value for money

5- Buy lifepo4 , and have rest of mind without babysitting you battery bank, no worries of not having a full charge everyday, have more juices to use.

Go for Lifepo4 please, More value for money

Can you put up your screen replacement up on Jumia, i have a device with a broken screen.

Kindly do that, if we can't get a replacement for your screen then the product is not worth it

Right now the device is just leing in the shelves, because we can't get screen replacement

Please i need help to understand this as a layman.

What make a charge Controller function as a 12V or 24V spec

Is it when you have a battery bank of 12V then it function at that level or 24V and function as same?

Or is it that, same way u connect battery in series to achieve 24V you can also connect panels in Series to make the Charge controller function as a 24V

Max. PV voltage: 50V

But can take 750w for 12V
And 1500w for 24V

This confuses me

Won't the Max PV voltage exceed 50V on 1500w panel arrays

With the 1500w 24V setup panels and charge controller can u connect a single 12v battery without any issue.

Make una help me explain abeg in laymans terms

earthrealm:


ooh, you are team yingli too?, too bad. i got the memo late
yours poly or mono?.

wudda made a lot of noise/advert for them, but they aint paying me a cent for endorement/advert, so amma keep my big mouth shut

Where did u buy from. I need ohhhh

ojeysky:


8.6A will charge an LFP it's just a matter of how long it will take to charge. You should get a more powerful charger, i think @Juo said he has a 40A.
Fyi I have a 50A 24v

Ok just wanted to clear that out. Thanks for the answer

essegis:


Without BMS you will need manual intervention. This becomes tiring over time. Except you size your bank such that charging and discharging always falls within the wanted parameters.

There are a lot of guys that actually don't believe in BMS as its the weakest link in the Lithium chain. Except of course you get money for Batrium and the likes. I wasn't dey there oo.

Yeah the guy on the YouTube link talk about balancing, and he said onece in 4-6 months

But i was thinking if i stay within the allowed charging and discharging capacity will that be fine without BMS?

Also it seems like Smart Chargers for lead acid battery will also do better in charging of Lifepo4, the highest Volts on my smart charger is 14.8V the amp the highest amp is 8.6A for 12v and about 4A for 24v

Most of the voltage i have seen for lifepo4 is 14.4V my question is will the 8.6A be enough to charge a 12.8v 105Ah bank of Lifepo4

Wow i think i am more comfortable with Lifepo4. Still trying to learn more about putting them together, and appropriate way to charge them and also about the balancing issue

Need to learn more about the balancing, i will like to ask is BMS actually needed on a lifepo4 set up, if you charge and discharge appropriately? I didn't see this guy using any

I don't know if I'll be banned for this link. But it's the link to those screenshots I uploaded above.

This was nicely put together. Wonderful piece, now i have a better understanding of the Lithium family

Lithium is not just the future, lithium is the way to go, glad to see that Lifepo4 LFP is very safe and can withstand some level of abuse

Thanks Ceaser for bringing thins to my reading i am so grateful.

earthrealm:


just checked, batts were bought in mar 2016, 4yrs, not 5yrs

4 years and 3 months. Is like you know how to maintain lead acid

Which brand?

ceaser:


I think you should be careful with getting the inverter via Jumia Global. Someone here has posted before of an inverter he got via Jumia global that was advertised as Pure some wave but turned out to be modified wave.

Some of those Jumia global also source the products on sites like AliExpress, so if not for the Corona problem that has slowed down things, I'll have suggested you place the order directly on AE yourself. I have seen this inverter on AE, I'll see if I can retrieve the link and post it for you.

Majority of Jumia Global sellers are sellers on Banggood, Jumia Global items comes with cheap shipping too, this same inverter is about 8-10k to ship from Aliexpress why jumia is 1200 shipping and 1750 customs

When ever i want to review item i see on Jumia Global i go to Banggood and check buyers reviews

That same inverter that guy bought i never rated because details about the inverter where scares, little or no YouTube reviews

But this inverter i have seen some buyers review on the Banghood and YouTube, and they agreed the sine wave in clean but the ratings of the inverter is not as stated that is a 1000w is probably 300-400w in real terms.

I can do with that but if the product go last na waytin i nor know,.

The rate brands dey cut money for inverter is just too much

This product have been on my radar since March this year, so far the reports are good


I am only buying this for now bcus of budget. Though i have not placed the order

ceaser:


Is that AliExpress page?

Jumia Global item

JUO:
4pcs in series

Ok Boss

JUO:
dc watts meter. Battery was not even fully charged and I stopped at 3.2v

Wow thats nice was it 4 of the battery you connected in series or it was above 4??

JUO:
first test. I think is better to stop at 3.1v. Let me observe the voltage after 3.1v

Wow this thing sweet , 1274Wh is it the juice you have used out of the system? I am in love with this

Please which meter is this that is displaying the battery and usage info

ojeysky:


Nominal voltage is 3.2, resting voltage is the voltage when the battery is not charging and not on load. That can be anything, but the figure when it's full should be around 3.35.

If you are doing 12v, you can get the makesky CC or any other MPPT controller. The inverter you are buying is okay, but if it has inbuilt charger, don't use to charge via utility as it not meant for LFP. I currently only have 24v LFP chargers may have a few more 12v in future but you can check jiji for those (if you are lucky)

Regards

Ok thanks my initial plan was to go 24V but lead acid, since i am going lifepo4 i had to settle for the 12V

The inverter does not have inbuilt charger it is a stand alone inverter

Ok the makeskyblue 40A or 60 which will be better as i don't want to use more than 4 panels 250-360w panel because of space, make landlord nor go vex for the roof mata

I will search for the 12V LFP charger

earthrealm:


The setup is 12v x 4 200ah Fla, 5yrs plus old....48v inverter

Wow that's great 5Years amazing thats 48V 200Ah bank

earthrealm:


ahhh, boss, you never sell that my morning star mppt cc
twas only 15k abi 20k that stood btw us and that deal then..

am still interested if its still available.

ihave observed 1804w from a 1680w (6 x 280w yingli panels) array, about 2wks ago, dropped to 1795w and held steady for over 3minutes.
this was hooked to a 25k 60amps powmr cc

Is your battery bank lithium or lead acid? 12V or 24V

JUO:
after a brief test of these little batteries, I am thinking of not selling anymore. They performed beyond my expectations. Imagine this little thing with some much juice without full charge

U be business man, u go sell na make i put ur money together first

Or na Idaboski go settle our matter

ojeysky:


You are correct except that it's not a full charge voltage but rather a charge voltage (bulk voltage or in lithium terms Constant voltage CV). This is typically charging the cells at voltage higher than the resting voltage in other to get enough amps in as the CC set-up permits. So you can charge a Lifepo4 up to 3.65v but the eventual resting voltage when it's full is about 3.35v..I personally don't charge up to 3.65 as it's not necessary, anything from 3.45 bulk will get your cells charged to at least 90% capacity.
I use the following at the moment for my 24v (due to solar CC float bug issues that puts my system into early float)

Bulk - 28.2
Float - 27.2 (note that you really don't need a float for LFP but I can't disable it unfortunately)
Battery cutoff - 24v

If you are only charging from utility your bulk would be fine at 27.6v.

Note for a 12v system you don't want to discharge to 10v, I suggest you stick with 12v at the minimum. If your system permits, 12.5v low disconnect is better. By the time you are at 3v per cell, you've already taken over 90% out of the battery

Ok so in calculating

Normal voltage 3.2V i.e 3.2x4

Or the

Resting Voltage 3.3V i.e 3.3Vx4

I will work on adding solar to the set up later, how many Watts panel do you think i need to plan for since i am going for the 12V lifepo4 bank

But i think i will start with Nepa changing first, bcus of Budget limitation, so what type of charger will you recommend?

This is the inverter i will be buying the 12V 4000W which is actually 1800-2000W in reality, its budget friendly and the review online seems to show it sine wave is actually clean

ojeysky:


Just imagine the level of inefficiency in lead acid. Apart from the fact that recommended discharge level of lead acid is 50% to get reasonable cycle out of it, you loose additional 10 to 15% due to Peukert effect. So when we say that a 100AH Lifepo4 is equal to or more than a 200AH lead acid[b] in practice[/b] I don't think we will be exaggerating

Now you see why i have been shouting lithium since last night, i was thinking of buying lead acid again ohh, my brother it is pure waste

If i can't get JUO deal on the lifepo4 i pray i do, na to connect with the guy that did you own be that.

I am putting funds together already

Money yab me when that ur deal was up. Lithium here we come

JUO:
bms

Ok so we will deal on the lifepo4 battery

JUO:
I don't have commercial quantity for now

The Battery or the BMS?

ojeysky:


While you can discharge a Lifepo4 to 100% capacity without major issues, it's not applicable to the voltage. If the voltage gets below 2.5v then the battery is toast. It's certainly doesn't look correct to me that you can discharge a Lifepo4 to bear 0 volts but you can discharge to hear zero capacity so long as you are still within the 3.6 to 2.5 band



Lifepo4 is one of the most interesting to put together, just like the lead acid indeed. Just don't mix up the series/parallel arrangement of the cells.

There is also one Specification sheet i saw of Lifepo4

It agrees with you submission

End of discharge voltage 2.5V

The 3.6V you talk about is it the Full charge limit


Am i correct

Lifepo4 for a 12V Bank

Normal Voltage 3.2V x4=12.8V

Full charge voltage 3.6Vx4=14.4V

Discharge limits voltage 2.5vx4=10V

Lifepo4 seems to look easy to put together just like lead acid battery

How true is this claim

LifePo4 battery can deep discharge till 100% DOD. Even the voltage goes down to nearly 0 volt shortly, it can still recharged to rated voltage

JUO:
yes, please note you need bms or you manage the battery through back door

4pcs of the Battery 3.2*4=12.8V

How much for the BMS

JUO:
If you are interested please indicate. Capacity is 105ah/3.2v. Price is 30k for less than 8pcs and 27k for 8pcs and above

If i need 12v will 4pcs be enough
