I bought it and I'm regretting it even though I got it from their accredited store .Fake too much .it doesn't work with half current while my Samsung inverter works perfectly on low current.
Because its inverter doesn’t mean it will compulsorily work with low voltage ok. You should have looked at the power rating before buying it. That is always the same with inverter AC. Not all likes low voltage look at the side or back you will see the voltage requirement
If the cells are not laptop extracted, I see no reason why it should work at a huge 7s. It goes beyond how he soldered. He could even spot weld but used a poor of fake strip.
I have 288 cells at 3s all soldered for a reason but powered 0.5h sumo without blinking.
Yes we can’t overrule that fact, poor soldering or welding can lead to multiple open/disconnected ings that’s possible what happened
Intellab:
I had some challenges with my previous 18650 battery setup. I used 644 cells configured as 92P7S, but it couldn't power my 1HP Sumo pump effectively.
So, I upgraded to 314Ah LiFePO4 batteries — 8 pieces in total, giving me around 8kWh of usable energy. I built the pack using a JK Bluetooth BMS with a 1A active balancer, 4*250w solar s, felicity MPPT.
Batteries and the BMS were sourced from Valto.
I also switched to a 0.5HP Sumo pump, and now I have 24-hour power supply. The Sumo, washing machine and a lot runs smoothly — everything is up and running without issues 24/7.
Probably you did something wrong or the cells where already losing there capacity, 644 cells that huge bro, maybe you used soldering iron to degrade their capacity while assembling it.

LIGHTNING STRIKES... BUT MY INVERTER STOOD ITS GROUND! 🔥⚡
Do you that video I posted about how lightning can shut down even the best inverters? Well, let me take you behind the scenes of what just happened — and trust me, this was not your average rainstorm.
It started with a LinkedIn post I read some time ago — multiple inverters within a 5 km radius had failed after a ferocious lightning storm. These were properly installed systems, with earthing and SPDs in place — yet they still failed. That got me thinking. That got me experimenting. That got me ready.
Then yesterday happened.
The heavens opened. The sky lit up like a thousand fireworks. This wasn’t just lightning — this was lightning on steroids. Strike after strike. Some so violent they triggered car alarms in the neighborhood. The whole area was under siege from Mother Nature herself.
And there I was… watching… waiting… monitoring my system.
GUESS WHAT?
Not a blink. Not a flicker.
The lights held steady.
My inverter stood its ground like a warrior.
My solution worked.
The theory became fact — and it survived a full-scale attack.
Whew. That was intense.
👉 Watch the full video to see how I solved a problem that takes down systems worth millions. If you care about your investment, you NEED to see this.

Good afternoon engineers, pls, I have 2500mAh and 2000mAh lithium ion battery cells that I am gathering to build a 7s pack to attain 24v battery system. Can I mix those capacities together in one 7series pack or Isbit possible for me to build two individual 4s 12v pack of the different mAh capacities to later connect both pack in series to get 24v battery system. And how can I balance that?
Thank u all.
You have no easy way to balance the second option but you can try the first option but be careful and be warned it is not safe it can cause fire when you treat those cells anyhow

OR
620w from Fouani x6 <125k each
(the key to getting this price is if you have of electronics seller that buy other things from Fouani. You can liase with them to help you order this straight from company)
6kva Luxsun/cworth hybrid inverter circa 450k
The other materials will cost 160-200k if the s will be on your roof and yiu stay in a bungalow.
If you don't mind DIY Battery, I can make 14.3kwh battery for you for 1. 650m
Workmanship, look for a competent person around you or hire from here.
I prefer you go with this because of the diy battery so you know exactly what quality you are getting for a better price
fuckboys:
i went for bread, but as per the fans, the bread inverter fans are always running round the clock even with little or no loads on the inverter.
Don't know if it was designed that way.
What problem do people have with a running fan in inverter ? Is the inverter installed in your sitting room of bedroom. Abeg make una leave Watin them write for body of Moto, enter moto
I am intending to change my 24V gel (lead-acid) type batteries to 48V LiFePO4 batteries and I came across some batteries that appear good on AliExpress. I am a bit sceptical about buying the 48V LiFePO4 batteries on AliExpress and shipping it down to Nigeria.
Please, does anyone have any experience on buying LiFePO4 batteries on AliExpress.
Ali express done Dey ship batteries, that would be nice but I doubt if you would get original batteries from Ali if at all they will ship it. Why going to sokoto when they are grade a batteries in your shokoto 😆

New build: 3s32p, 864Wh, 500W pure sine wave power station with external battery and monitoring via wifi. Just finished server and front end side. More updates coming in..
Where’s the inverter ? Did you build it yourself ?
I just dey put some things up jare. LFP wey I dey study daily since it got it 4 years. People go come dey quote AI or website that are trying to protect Dem self from warranty claims and all.
So they will recommend you to use their products like Eggs..
Anyways package back for anyone interested. 420k for the 3.6kwh Batteries
I know what a relay is. I have a first degree in Electrical engineering and masters degree in Telecommunications engineering.
Hey bro sorry I saw your message very late I also studied elect/elect but that aside you need at least 2 big relays, a transformer 12v, and a rectifier(full wave) you need it to keep one of the relays on standby so that it will not jam with the dc voltage from the inverter, it’s just a logic application it’s simple once u know it

...but there are MaintainNance Free Deep Cycle batteries na.
As for the so called war, I tell you say na person without personal experience go bother. Those wey Tubular or GEL / SLA / VRLA / AGM battery don serve, go hear all the praises rained on Lithium batteries, rush go buy am; hopefully they don't get disAppointed if they're Lucky or their useCase fits in.
Another set are FRESHERs (new Comers) to Solar world.
For the likes of Us wey don dey play with chemicals, from small, come still dey extract batteries from laptop batteries at less than age 18-years old dey build mini backUps, I wonder wetin those wey only got to know solar when it became popular thanks to APC regime wan tell us.
Personally, I decide when to go Tubular, and when to go SLA / GEL. Lithium has got it's place especially if size (Portability) & weight is a consideration - the more reason it's used in electric Cars / Bikes (weight factor) , Gadgets e.g Phones, PCs, etc (portability).
Mind you, Lead Acid batteries are much cheaper upfront than lithium based batteries. Similar reason a lot of people prefer buying Generator, than going Solar.
Lithium batteries can cost as much as 2 to 3 times more upFront.
What about Simplicity, and the fact it's been battle tested and rugged.
What about in places with much Heat ?
Abeg make I go chop. been battling with database data recovery for a new client since Sunday. To get client sweet, to collect Money sweet, but the work na die.
Na this kind time person Dey debate about tubular battery vs lithium? Chai..

i greet ooo...where do most of you get your components from ...I want to by a buck converter but don't know any place apart from AliExpress...
Ali express is good, you can get your stuffs there
I did, but it was only pictures, and no explanations. I for instance have issues understanding the battery configurations and how to tell what type of BMS will work for the configurations you use(e.g When they say 4S2P). I understand perfectly what a parallel and series connection is from my Physics textbook, however, I have no idea about it when it comes to arranging multiple cells like you guys do.
I only think of it from one perspective (the way we were taught in Physics class), and this is where my problem is. Even if I come with an open mind it still confuses me.
For instance, I know how to explain to you that a 128Wh system using a 3.2V 5Ah batteries can be built this way (attached image). You can see that my batteries are arranged in series in two sections to get the 12.8V (I.e 3.2V *4) and keep 5AH the same for each cells. Then the two sections are now ed in parallel to keep the 12.8V and increase the AH to 10AH( I.e 5Ah * 2).
So this is my problem—it is the only perspective I see it from. But you guys arrange all these cells as a bundle and create connections that I can’t just understand no matter how hard I try. To make it worse I start hearing 4S2P, like how 🥲?)
