AndroBlaze:
Another thing you might not realise is that if he switches off the charging profile of that inverter, it kills the ability of that inverter to act as an automatic UPS, which I can tell you from personal experience is quite stressful for him to changeover every time NEPA takes light.

At least, lets first let him worry about obtaining the battery. On the first day he can charge it up for a while and observe it directly if he has a multimeter (which everyone in this forum should at least have by now).

AndroBlaze:
Have you used a dumb indian inverter with a lifepo battery or is this another theory vs experience argument?

AndroBlaze:
Omotoda's advice was given based on the experience of using a similar inverter. So is mine.

He doesn't need to worry about another charger as these inverters don't even have equalisation modes if I remember correctly.

AndroBlaze:
The advice Omotoda gave him was sound. That inverter will work fine with lifepo batteries and won't overcharge it as the charging profile is on average lower than what is needed to fill lifepo batteries. Also those buttons have nothing to do with charging but control how fast the UPS kicks in.

It's still good for him though to get an external charger so that he can ensure he fully charges the battery once in a while.

Obnoxious2001:
It's not for the charging.

I think this is for the input from mains.

It's good someone has actually experimented the lithium battery with Indian inverters.

@brightk Hi, can I get my mini kit activated for service in naija?

odimbannamdi:
After changing the name of my Starlink device and setting up a password, it resets after a while and returns to "Starlink" as the name, without any password.

This makes people to crowd in front of my house, tapping into my network. I am worried about the security challenge it poses.

Is anyone facing this? How can I resolve it

GloryJoyeux:
Hi, you are connecting the panels in series, so it’s the voltage of the panels that is going higher not the current.

So no need for thicker cables to level you are insinuating for the dc pv input.

The best pv charger controllers have Isc of 47amps and Imp of 17amps. So its not the kind of high current your are imagining.

Battery life goes beyond capacity testing...

Battery continuous performance goes beyond capacity testing...

clevermugu:
lolz. so people pay 2.350m for thier Eve pack and wait for 3months , when it can be gotten 2.2m from Valto here

pazone:
Except they're not all brand new, at least from the one I tested.

The problem with Deriy 14.3Kwh Hithium White Battery with MCCB is the cells are not brand new. See the attached image of the QR code. How can you say cells manufactured in 2021 are brand new?! Or are these fake QR codes? Whichever it is, it's still false marketing.
The BMS (image attached) was programmed to charge at 40amps, new cells are supposed to support charging at 1c. Or are the Hithium cells in Deriy different?
In Southern Nigeria lifepo4 needs to be charged as fast as possible because of the weather, the sky is not always clear like in the north. So anyone with high PV output should be able to charge at 1c or 0.5?

One more thing is the Deriy 14.3Kwh Hithium White Battery with MCCB is not DIY friendly because the cells are welded (image attached)
It won't be easy to replace a cell if something goes wrong in the future. DIYers should have this in mind before buying Deriy battery pack. You get what you pay for but KaylaDeriy shouldn't be marketing these as brand new, they're definitely not.

Nice community you guys have here, researching this battery to get more info & Google landed me on this thread. Capacity test to follow soon, these are first observations.

jmaine:
So you are basically saying paying 300 - 400K for an express service is better... No sir... That's too high to be considered any advantage...

At the end of the day... Preference is all that matters for folks...

turok:
Can I register my starlink account in Asaba and use the device in Warri? Warri is already sold out but Asaba is available

Peterlove11:
I bought 16kwh from him recently. He delivered directly at my doorstep in less than 24hrs.
I did capacity testing on it, was able to pull beyond 316ah from the battery, that was at 48v low voltage disconnect.
He used JK bms on the battery which I later read from reviews its a good and quality bms.
I will give the build quality a 8/10. Quality battery terminals and circuit breaker.
Concerning cycle life, he said it's rept cells with 8000cycle life.
In all, I will recommend if you want genuinely rated battery with good bms
This is based on the battery I bought from him, can't say about other capacities.

AndroBlaze:
It is almost 100% certain that the likes of CWORTH are using grade B cells and not saying anything about it so I wonder why it is hard for people to recommend Valto when he is an actual person that will tell you the grade of the cells if you ask

jmaine:
Are his cells Grade A, B, or C?

FEGEITOK:
This is an objective question and not a diss or an attack.

What are the pros and cons of purchasing a battery from our guy here Valto versus any other packaged batteries?

I've read here that Felicity batteries overstate their capacity but that Valto states the real capacity.

What other issues play in favor of Valto?

If there are any cons, please share.

Want to make an objective purchase decision here.

This is going to be my first lithium battery purchase and I don't want to get it wrong.

Comments on the below will be helpful:

Capacity,
Cycle life,
DIscharge rate,
safety features,
Build quality

Will be helpful

This list is by no means exhaustive

HeavenlyBang:
Cells are cells. Advantages of buying from him is he has good prices and customer support.

turok:
Can you activate this for me? dm me

odimbannamdi:
By "cap at 50GB", do you mean once you use up to 50GB, Internet access stops? Please clarify me.

Lordave:
I really wanna do this, please can you put me through on it?

ask4bk:
Nigerians ehn.
I'm sure it's Nigerian workers with starlink that are pressing this secret buttons to update/activate guys.
Nigerians go use your business do business.

ask4bk:
But are they activating residential plan or something else? And why 90k

ANIKUDI:
On residential plan or Global roaming plan?

ask4bk:
Lol... I only did Maths. I didn't exaggerate.
Grandstream GWN7664ELR does 300m range. Let's use maths to calculate the square meters.

300 m omnidirectional refers to a radius in all directions — it's describing a range, not area directly.

300 meters of omnidirectional coverage is only a radius of a circle (not diameter):

Area = πr² =3.14 x (300)² ≈ 282,743m²

The unify access point I compared it with covers only 140m². That's literally 2000 times better in coverage/range.

You were right in saying I did unfair comparison. I didn't know unify had an outdoor enterprise level access point. Let's compare the Grandstream with the U6-PRO-LR then.

U6-PRO-LR covers 185m² as you claimed. I think you are confusing meters with meter square. You need to convert to same unit to compare. You compared Grandstream 300m which is in meters and not m² to unify that is in m². 300m radius = 282,000+m². That's 1500 times better coverage than your suggested unify LR.

A unify LR can't even cover quater of a hectare, but the Grandstream covers over 28 hectares. No comparison.

Unify is just like apple iPhone that's the cool thing to use, and so the company keeps giving low specs and people pay too much for it like iPhone. I even heard that to use cloud management you have to pay and subscribe montly. Something that's free with grandstream and tp-link. Chai.

I agree with you that unify has many services and features more than Grandstream, but they are mostly gimmicks that 98% of users won't need for an enterprise level access point. There settings options are cool though. Grandstream gives you basics.

Then you insulted Grandstream by saying you will recommend it only for non enterprise use. 😭😭😭😭🤣🤣. Something that takes 750+ clients compared to lesser for unify entreprise Access points. Chai... That insult enter sha 😁😁.

ask4bk:
I get you, but there's no room for comparison.
Unify enterprise level access points don't offer 4x4 mi-mimo on all frequencies. They do on 6ghz and 5ghz but hardly do on 2.4ghz which, truth be said, is what 90% of clients will use since only 2.4ghz travels far. Mine has 4x4 on all frequencies.

Also there enterprise level access point is boasting of just 140m square of coverage when my Grandstream offers 282,000m square. That's literally 2000 times better.

Unify, as a big name, are super costly when you can get Grandstream cheaper and does 2000 times better. Grandstream is an American company. Not Chinese incase you tempted to say Chinese make cheaper and less quality.

studyless123:
Sir, like I stated earlier calm down and learn. Life is not only about you, I know you use it for business but everyone else should not burn because of you. Starlink signed regulatory policies and if they can't keep up with it, they can pack and go. Price increase should be approved and whatever price they set is the least of my issue.

I don't care about the price. I know many individuals that pay more that that monthly. I can't use it because it's a CGNAT and I don't like their implementation because they use semi-static blocks of ports for connection. I was paying about 1k USD for ISP over 15 years ago and wouldn't have issue paying same today. You also don't have to tell lies to prove a point. The reason for the waitlist is clearly stated on their website, any other reason you're giving is your opinion.
Concentrate on your last mile connections which was what I did 20 years ago. People will appreciate you for that.

jonescosmos:
If this is how you have been connecting the Black Stacked battery, you are doing it wrongly bro.
One of your DC cable should exit from the first battery and the second cable should exit from the last battery.

ask4bk:
One unify access point ran 60 clients concurrently and it was smooth? Would love to know which particular access point did that. Most unify and tp-link omada will start to slow down especially as they are only 2x2 mimo or max 3x3. They are not enterprise level access points. You can't use them in a large setting like a stadium of thousands of people.

My Grandstream is 4x4 mi-mimo. Can theoretically take 500+ clients at a go, though the highest I've seen mine take is 72 clients at a go with smooth experience for all.

Unify is great for hotels where many won't be connected at same time to one access point. But not for a public commercial use that could draw 100s of users to one access point.

ask4bk:
Grandstream GWN7664ELR

Its not the big names like unify or omada, but this is an unpopular access point that is enterprise grade which I doubt any omada or unify is. I used it to replace my omada outdoor which was making my clients complain every time when only 20 people connect simultaneously.

Bruteality1:
Good evening. Is there a 7.5kwh battery on 24v for my 4.2kva inverter? I don't want to change my inverter but want to buy the lithium battery with a higher capacity. Is it possible cos the ones I'm seeing is 5kwh on 24v.
