Do you build lithium batteries. If yes please send me a message.

I build for self use. May transition to business when I perfect what I'm planning on.

Trippledots:
You reside in the US?

People reading there buy RE stuffs too, just threw in my own.

FEGEITOK:
This is a mixup.

I wanted a 4 battery pack that I can use to jumpstart the car and if I am very adventurous, I can use it instead of the LA battery in my car.

I just need 4 cells and a BMS.

Hence the expression jumpstart pack

I bought grade B 100AH Sinopoly lithium cells in China 4 years ago for this. Battery still in use for such practice till today. Crazy thing I'm using it without BMS.

kristien4:
Yes, i understand the read and black wires in the diagram, but what are those white wires, is is part of the connection for the equaliser?? If u notice, there is a white wire running across each series, na that one dey confuse me..

Yes, those white wires are part of the sensor wires to check the individual battery voltages. Maybe another image attached will help.

Update on the AC:





° Another one hour and I noticed that the consumption had ramped up to 271w and stayed there. Since I wasn't at home, I couldn't tell what was going on. I came home after 2 hours and noticed that the external unit had kicked in, and was probably responsible for that ramp up to 271w from the initial 15w. The room temperature remained at between 26deg to 27deg. It's four hours after and the consumption had further dipped to 267w

It seems there is something "energy saving" about this unit after all. Although I assume temperatures still get to as low as 18 deg with these ACs, the 26 degrees notwithstanding is adequate for a lone me in the room.


NB: Pardon the long story. I just felt being detailed enough helps to inform readers, and maybe prospective users, better on these things.

This is good to hear.

ibietela2:
Please who has tested the growatt's ES5000 without battery?

Sorry to ask, why will you want to run this test? You do realise even if it works and sun dips, as it usually does, that whatever load the inverter is powering will go off?

Xanderone:
Okay. I'll search further. Thanks.

Edited: I've spotted some. And they're even way cheaper than the A&E and Prag offerings. Great.

Jiji prices are often suggestions. You get the real price when you contact the seller. All the best.

kristien4:
Please anyone with idea on how to connect a 48v battery equaliser to a 48v battery bank of 4s2p...??(8batteries)

It's best you follow the manual of the one you bought. Here's a 48v battery balancer from PowMr. May or may not be the same with the one you have.

Xanderone:
Thanks. Noted

Edited: The offers available on that website are all used o, both Stavos and Matsunaga.

I didn't come across a new one.

New ones are available. Stavol is produced by Matsunaga.

jonescosmos:
I will share with you my personal experience with these servo stabs.

THEY WORK AT THE BEGINING BUT WILL GRADUALLY FAIL.

Yes, they will fail because the movable parts on that huge toroidal coil will interact with the dusts that are settling on the spindle and coil. After a while, the dust might create a short circuit on the surface of the coil and then the stab will start dropping breaker or fuse due to the explosions from the short-circuit.
I have had this issue with more than four different brands, same issue ooo. Service center guys will try to file off the affected surface and it will work well only for the fault to return after a while.
I eventually stopped taking stuff to the service centers and started opening them up first damn the warrantee, see what went wrong and decide if I should go through the hassle of lifting heavy stabs to service center every now and then.
So during my quest, I discovered that DUST IS THE WORSE ENEMY OF A SERVO STAB.

Then I switched to a relay version and I have been using it for more than 5 years and counting without a single issue.

My Advice: If you must do a servo stab, make sure it's dust proof.

I have been using a servo AVR for 8 years now. Yeah, dust is an issue, as long as the coil is great, you are good to go. Mine was even bought used. I don't think I'll get the regulation I get from this from a normal relay AVR as this beast can handle crazy NEPA low voltage (which I hardly use). A relay AVR will truly struggle to do what it can do.

Xanderone:
So I don't wanna make another terrible error, this time with a central stabilizer. I may need to get one anytime as I was able to secure a prepaid meter that has for a while been installed but not used cos it had some error codes which made me unable to load a key change code and credit. The issue has been resolved. So I discovered the voltage supply is a terrible regular 160v and seldom 180v.

Stavol by Matsunaga is a better make. Go to JiJidotng and search for Stavol AVR or Matsunaga. They do make awesome servo AVR

I saw a Bluegate 20kva there too, that stabilizer can boost 130v to 220v.

kristien4:
How do you order from the US?

Have friends in the US is the best option. Or use third party shipper like https://heroshe.com/

Dam5reey:
Growatt was made in China, sent to the US then you bought from the US instead of China that is closer!
What's the catch?

Tax break. Green energy tax break. Lol

alosbaba007:
Maximizing Growatt inverter, putting as much as possible panels on it.

Ok. Panels just arrived today. Growatt is on the way. Shipped from the US. WHEN it arrives I'll update.

WILUG:
Quick question for all the gurus in the house...

I'm seriously looking at changing to lithium batteries. My challenge is the cost. I've also seen people advice that you can start small and add more later.

My questions are

1. Can multiple brands be coexist? for example, if i get a good deal on a 10kwh felicity battery today, and a deal on a 10kwh blue carbon tomorrow, can I add them?

2. can multiple power capacities coexist? say I can only afford 5kwh today, and tomorrow i'm able to buy 10 or 15kwh, can I add them together? or will I be stuck with 5kwh increments?

3. What's the maximum period between such additions? if I buy a lithium battery today, Can I add another maybe in a year or two? for tubular batteries, people usually say that it's not advisable.

Thank you.

Not recommended, but you can if you don't have a choice. Anyways when you do experiment of such nature, this may likely void the warranty on any of the product. As a DIYer, you sometimes just gotta do what you gotta do and damn what follows.

But if you'll love to do this, isn't it better to build your battery? I built my battery so I can do whatever I want.

alosbaba007:
My oga, hw far with your experiment sir.

Got a mail from Gennex today say dem don restock Canadian and Jinko panels, i say make i go check out the price and specs.

Attached is the snapshot of the datasheet for the 605watt. See the VoC and the Amps, hope its within range.

Remind me of the experiment you are referring to?

Xanderone:
From what I've read here, hisense' performance is better than LG's. But I don't think Hisense has at par energy saving options as LG has. I haven't even come across any hisense special names for AC the same way LG has (smart inverter, dual inverter) or Thernocool (Genpal)

Hisense ńa just Hisense. 😊

But it is always way cheaper than LG and thermocool which basically market their already established names. Not just their ACs but most of their appliances.

As per that deal, I hope they find buyer soon jàre. I don't like the way I'm seeing that AC everyday. It makes me mad with myself each time I see it or use it.

If una find anybody wey dey interested sha. I'm even ready to foot the logistics bills to the person.

That's true. I got a spec sheet photo of the LG Dual inverter spec

Xanderone:
So sad.

Seven productive minds lost.

Sadly, not going to be the last time.

Failure of government led to that. No one will run generator if there is NEPA supply, especially at home.

Xanderone:
So I checked on them Monday and explained my situation. But it isn't all good news jàre.

On the AC, they said they can't take it back cos it's been installed already. But they promised to help me get a buyer in no distant time. They said something however that caught my attention. That their AC sales (demands by customers) are mostly Hisense and that before they get to sell one unit LG, they've already cleared like 10 units Hisense ACs.

That's a good deal if you ask me.

Could it be because Hisense is cheaper than LG and works just as well especially for those not particularly interested in energy efficiency?

swagifted:
I went to kougar today to fix a bad video doorbell and saw this....

Money talking. Dang!

Drgreatone:
Chint only has AC components, not seen a dc part in my short RE journey. Dcs are basically hager, Schneider, tomzn I know abt.

Chint has DC. See attached picture for the Chint. See the fake Schneider

kristien4:
Abeg, is 10mm wire good enough to connect say 4pieces of 200ah batteries in series for 48v??

Get at least a 16mm cable.

Peterlove11:
My inverter stopped receiving pv input since yesterday. No input or fault error. I put the inverter off and disconnect it from all input sources(battery and pv), yet problem persist. Discovered the pv breaker is burnt this morning(I don't know yet if that's the cause of the problem). Can anybody recommend any good dc breaker both on the battery and pv side. Thank you

You bought a fake Schneider, that place with Schneider name is removable. Try moving it sideways and it'll come out . I talked about the fake breaker here.

https://www.nairaland.com/390522/solar-energy-complement-fta/1346#120371763

I'll advice you look for Chint product to buy. It's around 7k to 16k depends on where you source from.

Blaqq2:
Nipost cost?

Dunno. You just gotta go there to find out. You know in Nigeria you can't really find out anything remotely, not like they have a website where one can check cost. Even if they do, trust it to be 5 years out of date.

Blaqq2:
So guys I made a huge mistake while ordering a PC screen and ordered a slightly different model
I disputed and they requested I return it
Can I return through speedaf and any idea on the cost?

The rule of the game is not to attempt to return packages to China. The reason is simple, the cost of return may often make it unprofitable.

Try for other means of resolution that doesn't require a return unless of course you've checked and shipping to China is no longer expensive.

Speedaf do not ship to China from Nigeria. Your options are NIPOST, DHL, FEDEX, UPS, etc.

SyncForth:
Any idea if I can get the qcy earbuds in Owerri?

Jumia has the HT05

Their price not bad too @ ₦29k

Dam5reey:
Buy Hybrid 3.6KW with inbuild MPPT ~350K

Please which make is this?

Olamak1:
Not only you. same here!

They are back

IMAliyu:
Not just you.

I hope the eyes of this government haven't turned on to them.

They are back. They must've been running an upgrade or maintenance

durodee:
A point in time in my life before I went the Lithium way. I felt like a king with these Monbat batteries o. My first set of good rated batteries bought brand new .They served well and were graciously retired.

I've seen this Monbat at work, it's a great battery. The location I saw it it was on its 5th year of service. Though proper load management was done by the user. It's one of the best lead acid battery; better than most LA battery on sale today.

isnigeriadead:
i dont have honest review of consumption now since have disabled my monitoring meter long ago. All i know now is i can use my AC with all other average load of 300w till daybreak with my 12.5kwh lithuim pack.

That's interesting. It's pretty energy efficient.

vincentont:
Every minute chipper cash will just disable funding of USD. Now self it's N1,609 yet funding USD card is unavailable.

Klasha currently can't be funded.


@everyone, are you able to log into bitnob or is it just me?
