I have not yet carried out a capacity test, maybe later in the week, i'd just turn of my Grid and solar input, then go from full charge and see how much energy the inverter records as output over the course of the day.
I'm currently using Bulk charging at 28.2v, Float at 27.2v, Max Charging Current at 40Amps, Equalization turned off on the MPP Solar. Any recommendations to improve on the settings are welcome biko.
I would have taken it apart just to see the insides, but the whole thing is riveted! , I'm sure this is to prevent warranty issues as well. Lmao.

From the ventilation silts, it appears it may be a Daly BMS inside it, although they seem to have sprayed their own name on it . Worst Case, I 'd rip it apart and install a BMS of choice, but do i really need to access the BMS? Not sure so far. Afterall, I was using Lead Acid before now.
So far though, I'd say not too bad for the price of a spleen @ #425,000, with a warranty of 5 years, not too bad at all.

Awwwwwwn. The battery looks so cute

Can we have a more detailed breakdown of the internals please? Name/Brand of cells, rating, what BMS, compressed/clamped or not e.t.c

I had also reached out to them. Same out of stock issue so I just moved on and decided to do my own custom build.

I had been looking for a viable alternative to Felicity who also happen to go out of stock a lot.

There is some risk with a small player such as these - Will the battery stand the test of time? Will the company exist in 10 years? Will they keep the existing hardware and backward compatibility or will we suffer the pain of hardware revisions and upgrades where they drop support for the legacy product?

So, here is the story of how I decided that I really don't need all my internal organs;
Remember a few months back when this strange company came on the radar but no one really had much information....and we still don't sha.
.....

Well, since someone else had an interesting discussion with them, maybe I could have an interesting visit to them? Na so I enter motor, face the ends of Lagos (i.e. Epe Expressway), to the address provided on their website. The idea was maybe if I get there and actually see the thing in real life, then answers will be provided.

Arrived there after many hours of lagos traffic and discovered a small team taking a break from prepping materials for the manufacture / assembly of said battery units. So I got to discussing with them and got some info.

So they have 2 variants currently, 25.6v & 51.2v, Approx 5KWh and 10KWh respectively. The batteries are made up of 32650 LiFePo cells in the typical parallel and series arrangements we are probably familiar with already. Enclosures are made of steel, they have a couple of CNC machines and other tools to round off, finish and add aesthetics to the final product.
Still not too much by way of technical details, I was interested in the 25.6v variant, so, max charging current is 50Amps, Max Charging voltage is 28.8V.
There is a BMS and active balancer, but unfortunately no form of external communication to both. On pressing for the reasons behind this, reason such as, most average users are not really interested in communicating with a BMS (na una DIY people dey always wan chook and press something), warranty issues from improper configurations and misuse by the users and most importantly, the cost of communication capable BMS. The manufacturer is trying to keep the price down so it remains affordable (or at least as affordable as LiFePo can be sha).
There's a small LCD screen that displays the voltage and SOC though, so....

Anyways, after a couple of minutes with them, I felt convinced enough to take the plunge on behalf of the FTA Solar forum. But alas, there were NO UNITS in stock at that time. Due to the costs of scaling, logistics and general nigerian problems sha, they are only able to get a few units out per month. I was informed that they are working hard to try to scale up, get investments and generally increase production output but for now, dem dey manage as the whole Nigeria dey manage.

I promised to keep in touch and also got a promise that they'd try to squeeze a unit for me from the next batch.
This was about 3 weeks ago, anyways, last thursday I got a call from them, informing me that a 25.6v unit was available for the taking if i wanted.....na so i go do the surgery o.

Ladies and gentlemen....I now have a Pelton LiFePo battery, it does exist and it does look like its as advertised.
There's a 5-year warranty on the unit and there is the promise of after warranty repairs and support for a fee of course.
Pictures attached!

Hmmmm

Lmao @ awwwnnnnnn......make una no make me dey roll for ground abeg.
Yea, by the time I factored the cost, time and other things that'll come up for a custom build, I just decided to have some faith in them. Also, they were able to come through just in time for me. So I guess that worked out. I see you already responded about the internals, the thing is sealed up like CBN.
Regarding the test of time for both the company and battery itself, fingers crossed o. We just have to support them to support us as well.
Oh yes, in my conversation with them, I was also told they're trying to localize as many of the components as possible, including the BMS and balancer and then they'd work on comms too. So maybe there would be a hardware revision along the line, hopefully, it won't be too drastic and they would be able to retrofit their older units with the upgrades.
Tomorrow get belle sha.

Hi mctfopt,
I doubt every member need migrate to email to be enlightened. It's a vital info that everyone need to have access to.

Kindly find attached (Pic 1) what should be his layout based on the details he provided. With the looping method ensure the battery bank cables for +ve and - ve sides are NOT taken from the same string. Take one from the 1st string and the other from the last string. The first string shows the connections for a typical HA02 Battery Equalizer (or Balancer). The blue dotted lines are the links to form the "one giant bank". It ensure a more balanced setup, as he's rightly said. It must not necessarily be same size as the battery serial interconnecting links. The battery serial interconnecting link cable can be 35mm.sq or 50mm.sq, whereas the parallel interlink cable can just 6mm.sq or 10mm.sq (in Efuro's case). I also use 10mm.sq or 16mm.sq

Please, credit should go to oga Niyi... Sometime ago, I was faced with a serious unbalanced issue in a new setup for a client and Niyi took out time to explain this interlinking between paralleled strings. I've seen it depicted in HA02 manual but never give it a thought, until Niyi made it easy.
Accordingly, you can use 1#, instead of 2#, HA02 for a 2-string battery bank.

Moreover, Pic 2 is a better method to parallel the strings. Each string is independently paralleled with same length and same size cable to a common busbar... Cheers

This is complex. I doubt a picture would've done it justice. Thanks a lot for taking out time to drop a schematic. It now makes it easier for anyone to accomplish same following this your detailed drawing. Thanks a lot. Man will just have to spend more on wires, the cost of which pales in comparison to that you'll incur if you use the traditional 48v connection.

Thanks to all y'all sharing premium info for free

I'm only glad you still have your heart after this payment

I like their packaging. Wish you can push more charging current into it. I guess you can't have it all. Please update the house when you have time to run a capacity test. I like the so many ways to kill the rat now available to Nigerians in the lifepo4 space.

LOl. Yes, it does look nice and presentable. I'll update on the capacity test once done.
And it can take up to 50 Amps for charging, I'm only limiting to 40Amps on my end. I would like to believe the 51.2v model can do more amps for charging.

I dey laugh as I dey read your write up .... Nice one bro.
I see all my ogas don dey ask for capacity test and component breakdown .
Make others self dey ready sell kidney ontop their battery be that. But this their low volume of production go be problem sha, it is well... Running a business (especially ones that involve hardware) in Nigeria is tough.

Just thinking out loud though, I think the fact that they riveted the whole thing down might mean they are not expecting any thing to break internally. Which is a good sign,I guess

Thanks for sharing with the house boss... please keep us abreast of how it performs in the wild, whenever you can.

So far though, I'd say not too bad for the price of a spleen @ #425,000, with a warranty of 5 years, not too bad at all.

adrusa:


I don't know what else "lithium profile" on a charger mean other than setting bulk, absorption and float voltage to the same value and disable equalization. That is exactly what happens when I select "lithium profile" from victron charger. As to the fear of continuous float charges on the battery, the BMS usually does the remaining. When my lithium batteries enter "float" the current meters read zero.

So, if you have a perfectly good charger (inverter or Charge controller) on which you can modify the charging parameters, I don't see the need to waste extra money on any "lithium" profile, I honestly think it is a scam for manufacturers to make a little extra money on selling their inverters and chargers.
