Stay with whatever works for you. But do not condem what you have not tasted out of mere say. Na that one dey pepper body.

u talk too much without making any meaninful impact... u do dis u do dat... are u more sound dan the manufactureres of hybrid inverters........dont generalize everything because we dont have SON doing their jobs on imported stuff...

IllRatherNotSay:
To add to this, the 700 cycle time has further been reduced by the fact that the batteries have sat for months on the sea and further at the warehouse of the retailer. I have seen a brand new battery at 11.5V. Sulphation is real for LA, another reason to go LifePo4.

isangjohnson:
Please what is capacity of this inverter?
Does it have Lvd?
What is the idle power consumption?
I know it's 24v system and I want to use it with lifepo4 battery

abcabc234:


its bullshit wen we claim to know more than the manufactureres of certain devices.... that someone bought cheap hybrid doesnt mean all hybrids are s same..

Goodafternoon my people. I have 1pc brand new Quanta battery for sale. Client that I am buying bit by bit for need money. Wasap 09077711266 or call 08033735359 make we talk

Felicity isn't among the best in terms of lithium battery, its like buying a kia and expecting it to behave like a benz, if you are out of warranty...then it could still be fixed, unlike leadacid, once its dead..its dead... the felicity pack needs to be opened, top balanced and a balancer added. depending on your budget, the bms could also be changed to a Bluetooth type, that shows you the capacity and voltage of each individual cell inside. this is where custom or DIY battery packs trumps these low end factory lithium. this ops I outlined above would have been super simple on a custom pack, but would be more tedious and expensive on factory packs because the cells are welded together, not screwed,

if you are in my zanga, may hv considered helping you fix the pack, however confirm your location, you may be lucky somebody knowledgable about lithium packs would be willing to help you repair it.

don't mind the kazeems saying lithium is bad...it reminds me of the car kazeems that discouraged people from buying automatic cars when it came out, giving foolish useless reasons that sounded ok to them...when the koko was that..they simply didn't understand the new technology!!!.

agh agh so you’re saying you have been observing uncle @bassdow for a while that he has a fat mouth 👄 and likes to sha type a lot based on his opinion….. no offense

@bassdow I'll apprreciate if you can post some of your setup pictures. Visuals are easier to assimilate.

I love the idea of converting your appliances to DC to run them directly off battery. It does eliminate conversion wastages and present few point of failure.
I didn't see your response to someone that asked how you manage to eliminate voltage drop over distance or if you have battery in each room.

I'm tempted not join hybrid vs non-hybrid and lfp vs lead-acid convo. So many of us are where we are today because of the knowledge freely shared here. You said most of the LFP around are scrap, I'll add that most of the lead-acid battery around are crap too. The question then is which better? I lean towards my experience and that of a few long-standing users of this thread who have equally migrated.

I started out in 2008 with cyberpower 24V 3.5kva with two 12v lead-acid battery. I had to replace one of the battery within 2 years and later increased to 4 batteries. I introduced victron battery balancer after replacing the battery as I envisage that the battery might have died from imbalance. I have had to replace battery 5 times in the course of 14yrs even with minimal load of less than 500w. Probably I got poor battery. Despite that the inverter was capable of charging at 60A I hd to set it to less than 20A so as not to stress the battery. The self concumption of the inverter at no load was 70W,inverter efficiency less than 80%. This means that the inverter consumes much of the backup power. These are few of the cons of my previous setup.

Compare the above to now that I used a hybrid inverter with 92-97% efficiency, LFP with 6000 life cycle (that is in 16yrs capacity is expected to reduce to 80% not that it will die). I can charge as fast as I want and discharge as much as I want. I can cycle it at 90% continously without worrying if it will die suddenly.

In the short term, an LFP of 120AH is equivalent to a lead-acid of 200AH in terms of capacity while the LFP would be able to deliver better instantaneous amperage.
In the long term, the net cost of LFP is lower than that of lead-acid.

This is my personal experience, which is totally different from yours. Will I superimpose my opinion on yours? No, because your use case may be different. Understanding the technology behind a product and using it within the spec sheet gives peace of mind. They are people who hve used the product you bash here and there for ages without issues. You can ask them for tips.

I didn't see your response to someone that asked how you manage to eliminate voltage drop over distance or if you have battery in each room.

So why are you telling us what you have done if you are not willing to share?
What's your motives?

The knowledge is common knowledge and too basic to be hidden in my opinion. If one wants to, most HND students and some road side electricians can do the converion

bassdow:


which one is -message deleted ?

Who're you trying to fool ?

A click on ma username takes me to the post you made to look like it's deleted.

Wonder how one could trust a sleazy fellow such as yourself.

if wetin I dey write dey affect you, why not just ignore me. maybe I would tire when no one gives me attention. Who knows, mayBe i crave for attention

Quoted message don't get deleted on nairaland. I removed your message from the qiote because it was too long while I retained the quote so your original message can be referenced.

You don't need to be super suspicious of everyone's moves. We are here to learn.

No harm was intended; don't get pissed off. Or is it a way to digress from the discussion.

bassdow:


na talks such as this, dey make me talk.

Una go dey yarn like say the other no get em own PROs and CONs.

1. You say CycleCount, like Lithium chemistry it's self don't have it's own cycleCount,
2. You say Sulphation is realt for LeadAcid battery, but there's something called “pacifying layer” in Lithium chemistry.
3. Every battery chemistry suffer from selfDischarge
4. Every battery chemistry have a lifeSpan and that would diminish even while still on the shelf and still brandNew.
5. what about AGing ?

most things said in here, are nothing but sales pitch. Mind you, I've got Lithium batteries myself. those I harvested, and those I bought.

bassdow:


so you want us to go back to LeadAcid battery when we have our HighQualityAlmight Lithium batteries just because your client needs money.

I don't bash or condem Lithium batteries.

Just saying that a lot of these battery packs being advertised are not worth it.

And NO, I don't superimpose my opinion on others.

And yes, it's far easier buying rubbish Lithium when you buy those battery packs than when you jejely buy leadAcid battery. if we could have a couple of Nigerian companies who couple such battery packs using quality cells and parts, I would sing their praises harder.

My major issue is the way and manner they make their wares (e.g batteryPacks) seem like a saint with no single fault annd the best in our lifeTime.


well I didn't wire the entire house on 12-volts. The voltage drop would be crazy even if I choose to wire the house on 48-volts.
what i did is, I have my home office and ma server room and those are the place where I did what I did. still expperimenting on converting a CPU motherBoard to run entirely on 12-volts system with no form of invertion but don't have time to further it. At the moment, most run on 24-volts or directly on 240-volts mains.

My laptops either run on 19-volts (i boost 12-volts to 19-volts) or run it directly on 12-volts like I currently do. Works well for laptops with no centerPin. These are things, that had I found in market, would gladly pay for; and I'm sure a lot more people would.

A single 2-year old 150AH battery currently power 2 core i5 laptops for over 2-days on single charge. Tell me lots of Nigerians wouldn't gladly pay for such should they find it. I searched a lot for such before i decided building one for myself. of course I have had challenges but what good thing doesn't.

So imagine when i find people coupling poor, low quality lithium cells with superCheap PWM chargeControllers, laptop charger into a metalic or wooden box and sell at very high prices. and you exppect I just keep mute. Just so you know, I have never bought such BUT that's because I probably have experience there. How many people are that lucky.

Even when I say certain things here, it's so someone picks up on it and give it a trial.

As we grow, we tend to have less time than we used to. Wetin una dey wait for, na make person suffer put together such circuitry, then the moment una see say people dey buy am, una wey don dey established in the circle, and with more funds, and outlets, would quickly duplicate it and the original person ends up not recouping even their initial expenses.
Common to think out of the box dey hard us. na to copy wetin another person don do we dey like.

those in the business of coupling lithium cells and selling it, could make smaller versions that would power things like TV, laptop, etc for several days on single charge and see if lots of Nigerians won't jump on it.

I can't even use sachet inverter sef because it would give less backUp time than I currently get when I SKIP the inverting stage.

My flatScreen TvMonitor is rated 19Volts but both the 19-Volts TvMonitor, 2 other laptops, and my outDoor Tv antenae are all connected to a single 150AH battery with no inverter. Funny thing is, the external Tv antenae draws power from the USB port of the TvMonitor. All I did was rip out the transformer isnide the Antenae, and wired a USB cable to it and pronto, e dey work, though e no dey rotate but that's of no use to me.
Now imagine one creating a product out of this and tell me it wouldn't sell like hot cake. A lithium battery would be less bulky, while delivering more Amperes per KG of weight.
you could even for a fee, help people convert their existing TVs, gadgets, or make suggestions on the sort to buy that requires no conversion.

if I am to buy a TV today, I look out for those with external power adapter/pack. Even if dem write 21-volts for the body, I go try am for 12-volts becase chances are high, it would work. Even if it doesn't, it's cheaper boosting to the exact voltage, than going from 12/24/36/48 volts to 240-volts, only to have it stepped down again to say 19-volts of which would still be further stepped down again to something much lower.

See eh, when you're good at what you do, even your enemy would have little to no choice than to patronise you because at end of the day, they want and need what you've got to offer. it's because a lot of us are not unique, even the copyCopy sef, we ain't good enough, is reason we struggle so much.

Anyway you can show us how u connect ur tv directly to the battery here or I private chat you. My TV uses a dc adapter and is like the biggest load on my inverter presently. Thanks

There are a lot of messages one needs to ignore in this forum

bassdow:

How many Volts is written on the back of your Tv ?
I mean the voltage on the back of your TV. if possible, show us a clear image of the back of your TV. Chances are, it's between 21-volts or 19-volts or maybe below.

one of mine is 19-volts, while the other is 21-Volts and both works perfectly.

The connection is very very simple.

Obnoxious2001:

LVD is 10.5.
It's not suitable for lithium battery.
Except your modify it externally.

You add a low battery cut off of the lithuim battery you want connect

If you have good installer in Benin, please let me know.
I designed a small 12v 160ah lifepo4 battery with 1.2kva 12v Tbb inverter, 80A Felicity Mppt CC and 2 pcs of 345w Jinko pv to power 120w freezer during the day and 45w LG tv, about 3 ceiling fans of 14w each and few lighting points (energy saving bulbs) at night for my friend.
The guy called two different installers and he was told the system will not power the stated loads.
