3 years cell warranty

Cycle count of brand new > 280ah are a minimum of 6000 cycle @25 degree.
100-200ah cells are generally shorter 2000-4000.

Bankyshinani:
How many years warranty and what is the cycle count?

Chiefs,
These are what I have at the moment.

12V 4KWH REPT 100A/200A BMS 460/470

150A BMS
48V 314AH REPT (16KWH) 1.8
150A BMS

bassdow:
Okay
Now kindly contact both mrReed and Valto and ask for their prices for 24v 8kwh and 5kwh batteries. Also ask the prices of those that have communication support and those that doesn't.

That way, we expect you report back with about 4 prices or maybe even 5 or 6 different prices if we're to consider those with wooden body.

Kindly notify us when you done with that EXCEPT you already have a prefered alternate sources. Except I am buying batteries, me no dey too like recommend.

We need know that price first before going any further.

Dami sells the 6kva for circa 550k
I believe you will also get a better price for the protection boxes.
Bread currently sells 590w panel for 116-118k in Lagos.
You have no business with 5kwh batteries

jFrankNorfleet:
I'd run installation for my gamehouse within the next 2-3 weeks

Pls house I need you to tell me what's wrong with this quote given by my prospective installer. Focus less on the price and more on if the setup will be okay for the gamehouse and how to prevent issues with the setup


These are what the gamehouse would comprise


Lg LCD 32 inches TV 140w *2
Samsung 32 inches led 56 watts *3
Samsung 32 inches lcd TV 110 watts *2
Samsung 15 inches lcd TV 40 Watts *3
PS2 fat 80w 3pcs
PS3 super slim -85Watts 2 pcs
PS3 slim-85 watts 5pcs
PS4 slim 100w 2pcs
Ps5 1 pc 200w
Yokaho DC ceiling fan 40w 1pc
1 duravolt 18 inch standing fan 27w 1pc

Note: I'm yet to get ps5 but it's in the pipeline. Also only 7 out of the combination of 10 PS3, ps4 and ps5 can be operational at once due to limited number of 32 inch TVs




This is what he quoted for me for the above setup

Is there something that should be tweaked for more efficiency?

To use this simultaneously, it is better to replace your kitchen socket with a changeover or properly rated breaker. Otherwise, you might be replacing socket occasionally

justasitis:
Next time you can go for double infrared cooker if you have high battery capacity. Something like this

The difference isn't significant

OgogoroFreak:
infrared consumes more energy than induction

Shenzhen Deriy, Shenzhen Starmax, Shenzhen Basen, Shenzhen Rowen (this one sell more used cells than new)
Your main challenge will be getting a shipper because most of them are not reliable.

Pabodo:
Hello House,
Doez one know
1. Any reliable store to buy cells on Alibaba?

2. Shipping cost (Sea) to Nigeria and how to claim it

Will appreciate advice on this as I am planning to get some cells

For the pack to drop that fast, Battery capacity is gone.

Marykhay:
Happy Sunday my people. Thanks for all your inputs on my predicament so far.

Like someone advised that I should charge the battery full today and measure each cells of my system. Here are the results below. It is worth noting that immediately it hit the 14.6V mark on load it went down to 13.9V:

Battery 0 -> Battery 1 = 3.51V

Battery 1 -> Battery 2 = 3.49V

Battery 2 -> Battery 3= 3.49V

Battery 3 -> Battery 4 = 3..49V


The problem, like I mentioned earlier, was that the 768Wh 12.8V capacity does not even get to half of what it should be.

More Context:
I use 3 units of a 180Watts Panels running on a 60Amps PWM controller, and a Sachet inverter.

Further Context
In just about 10mins under a load of about 40Watts it drops down to 13.1V which I always feel is not normal, but hey, that’s why I’m here.

So pls house what could be wrong the system? Thanks in anticipation.

@dollarnaira
@penuelseun
@capnies
@adimx
@Mrreed
@valto
And co

No vex chief, I am not that frequent on the forum.

Marykhay:
Good morning Chiefs,

I’m having a head start with my issue.

With regards to this system I posted earlier, these are the readings I got from the 4S configuration using the BMS connection the builder did:

Battery 0 -> Battery 1 = 3.18V

Battery 1 -> Battery 2 = 3.18V

Battery 2 -> Battery 3= 3.18V

Battery 3 -> Battery 4 = 3.2V

The problem, like I mentioned earlier, was that the 768Wh 12.8V capacity does not even get to half of what it should be. I guess this result is giving me a conclusion already.

But I need to hear from experienced builders:
@dollarnaira
@Mrreed (you no even dey reason my matter 😭)
@Valto (Senior man, at least say anything)
@capnies

Please what do you think is wrong with this system?
A. Weak or refurbished cells?
B. Unbalanced cells (I don’t know if the imbalance in the reading is negligible) causing the system to not reach its complete capacity?

Aameen, thanks Chief.
Yes I still have

capnies:
GOD BLESS YOU BROTHER AND MAY YOUR DAYS BE LONG .
I've suspected that, but I wanted to hear
from him.

I talk less and observe more, I am so happy for you, good legacy you'll leave behind and it will endure. into the new earth.

Do you still have the 314ah cells

Chief, let me help. Pack builders build with what is available. You will most likely buy from what your supplier have in abundance and can guarantee it's durability. See Deriy for instance, they have used hithium, Eve, CALB, Rjtech, Tianeng and many more.
As for Gotion, there are reports that the battery bulges quickly and data from the report also suggested that they are not closely matched. This is similar for Gangfeng too.

capnies:
@VALTO
WHY DON'T YOU USE GOTION CELLS FOR TOU DIY PACKS

8cells,yes

capnies:
How many cells can this you casing handle.
The terminal is it upto 200A capacity

Yes sir, 314ah Lishen 82k, case 60k, terminal 8k

Tdoctor:
Oga Reed, can you sell battery and casing with cable connector i.e. everything, but without BMS? Because I need the comm ports and don't mind buying batteries and casing and everything else, but get BMS by myself?

Here you go

adibo:
Good morning all. I am thinking of switching to a 8kwh lithium battery. From what I have seen, the major options are valto, mrreed, haisic, cworth. Are there other good options? For those who are more experienced, which would be the better option for me?

Also, I have noticed that 5kwh battery from valto is almost same price with 8kwh by Mr Reed. I will appreciate if those who are experienced can explain the extra benefits of valto's battery.

Lastly, please, can I see your 8kwh battery @mrreed

Pleae, I will appreciate responses.

Have you checked all your battery terminals?
If any of the cells have slightly loose terminals, this can also happen.

oluchibabe:
Thank you for your response.

Yes, it works well on very low load, like a few LED Bulbs and Phone chargers and Router and fans even if l shut down everything and put on say a Cooker or Freezer or anything above 1Kw, it simple trips off and display fault error.

870k

shoesaffairs:
@valto @ Mrreed how much is 8kwh 24v battery?

08131199386

johnchins:
Can I have mrreed contact details please?

Metal

ajabani4allah:
Is this with wood case or metal?

870k for 24v 8kwh now

cutefy:
Bia, Married, is the price above for real?

Wood is easier to use and I havnt experienced any safety issue with it.
If you will be using metal case, take insulation very serious. Test verywell and ensure that your case is not conducting.

Tdoctor:
Please house, I need a fast answer on this. Is wood safe for a 48v 15kwh lithium battery enclosure? I'm planning to use HDF wood. Any one with experience? MrReed, Valto, Dam5reey, Bassdow, Everyone?

Yes sir

favouredbymercy:
Can you share a pics of the one you have chairman?

From alibaba or find those that build electrical panels in your neighbourhood

capnies:
Please our lifepo4 battery builders where do you buy casing for your projects

Only that they are slower. If you have used the infrared or induction cooker, you will agree.

justasitis:
From experience those hot plates attached to cooking gases are also energy efficient as they can be regulated to reduce power consumptions. The hot plate on my gas’s cooker consumes 1kw at maximum and 200w at lowest. Induction cooker also has regulators to control power consumptions but may require special cooking pot to achieve optimum temperature.

I use one and also have a few for sale. It doesn't surge and you can always regulate the consumption.
Single phase, 28k

dollarnaira:
Thanks but the problem with them is the "surge". Do you use it personally? Further input will be much appreciated.

Freetech:
How far? Is this available now 24v 314ah cells?

If yes, what type of cell you have m rept, hithium or eve?

Already arrived and sold out.
Send me a message on WhatsApp so I can follow up with you

A rabbit hole it is and I am sure he has learnt a few things from it.
Sellers with no reputation can do this if they sense naivety.
There is also possibility of honest mistake too. Most of those sellers with Shenzhen addresses share warehouse with other sellers in Dongguan.
Many of them will probably forward your shipping Mark to actual stock owners to ship on their behalf .

If after random test, the cells manage to pull full capacity, alhamdulillah.

mctfopt:
Chinese lithium battery market is crazy.

Loads of shady deals going on there.

If you have a good supplier hold am tight.

The rabbit hole is sure very deep.

My guy bought 250 pieces of 100AH supposedly new cells. Cells arrive and it's used cells with a new cell wrap. Supplier is saying they are not aware. Case still ongoing.

DIY is still king. Can't have it any other way.

Not at the moment chief.
May be in about 2 weeks time

Freetech:
Hello @ mrreed, do you have DIY 25.6 300ah battery? Ho much and timeline for delivery after payment?

It's also important to note that nominal voltage differs based on battery chemistry. Your calculation is only correct for lead acid. For LFP for instance, 12 8v will be 12v, 25.6v for 24 and 51.2v for 48v batteries.

BigDickProblems:
Always multiply the AH with the voltage off the battery to know the Power/Capacity of the battery.

For example, there are 2 batteries:
(a). 300Ah, 24V
(b). 200Ah, 48V

Their total power capacity is as follow:

(a). 300Ah, 24V becomes = 300Ah × 24V = 7,200Watthour which is the same as 7.2Kwh

(b). 200Ah, 48V becalmed = 200ah × 48V = 9600Watthour which is the same as 9.6Kwh

Bottom line here is that if you are getting a battery (which I’m assuming you are trying to get), check the Ah and Voltage and multiply both to get the Capacity of the battery. With this knowledge, you can now go back to your first question and figure out the answer and also how confusing it is too 😂.

That was me assuming you already overstated the load. Even those white double opening freezer with old compressor don't draw 400w continuously.

ask4bk:
Thanks bro..
With full capacity load of 5000w, you still advice for a 6kva inverter?

6kva inverter is fine
The 30kwh battery is fine too.
Based on your explanation, 5-6kwpanel should suffice

ask4bk:
Nna eh.
I ask WAEC question, you change am to JAMB question 😁😁🤣.

It'll only replace gen, meaning it's purpose is only to take up those hours when there's no nepa (let's say max 5 hours no nepa - but you can't trust nepa sha). They still intend to use nepa.
Forget the fridge watts, u can clearly see it's a mistake.
Assume that they'll be powered at same time.
Any where could be upgraded any time.

dollarnaira

I was thinking at least 30kwh battery.
Its inverter to use that's cracking me head.

Press and hold the function button, you should be able to adjust your charging voltage and cutoff from there.

Royle2014:
Unfortunately this one doesn't. Had to connect to battery terminal and turn it on just to show u.

I have checked d manual both online and offline but no secret menu

Is there a way you can check the individual voltage of the cells without voiding your warranty.

Monsieuryankee:
The panels are producing 2200w in bright sunlight and about 800w in dull sunlight.
