Good day all. I recently got two 220AH Luminous NRGT batteries (Tall Tubular) and my inverter indicates the batteries are full. When measured with voltmeter without load they jointly read 25.6V.

But when I put load on the inverter, and put on like 5 led bulbs, the volmeter immediately drops to 24.4V. I'm surprised in the sudden drop in voltage.

Is this normal or there is something wrong with the batteries.

Inverter is Luminous Hybrid also bought newly

I am keen on knowing how this plays out as i intend buying exactly this same battery soon.

...following...

earthrealm:


ol boy. where are you getting your supply, abi u wan import am yourself. your main in jos is saying 1.5m for 48v 300ah lifepo4

That's like 500k per 100ah. Last I conversed with him, his 48/100 was 480k. I guess dollar muxt have been doing him strong thing too.

5 led bulbs, unless they are about 60w each on a all 1.5kva inverter should not cause such a huge voltage drop.

Do the following and tell us.
1. Get a hydrometer and test the specific gravity of each cell in the battery, you should own a hydrometer since you went flooded battery route.do this test when the batts are charged fully.

2. Use a voltmeter to test the output voltage of the inverter, during normal charging, before battery gets full

Good day. thanks for the advise on hydrometer, will get one tomorrow.

When charging, I used my Clamp to check, it reads 12amps (i.e what my inverter is sending to the batteries). When I started charging this morning, it moved from 24.8V to 25.8V and moved to 26.3V after 2hrs30 minutes (still charging). So I think like 1V is added when charging.

During my search online, I read about sulfation. And I did the following, ran the battery for 8 hours (5 led bulbs ) and reduced the acid level to the marked points (Guess Luminous just filled to the brim without checking the max point).

Sorry, not familiar with how to use voltmeter to check battery charging capacity. The voltmeter records I post are from the installed voltmeter beside the batteries (bought this just to monitor).

Hi experts, I have 80 watts panel on a 480 watts battery
The worry here is I want to charge my phone while the solar is still charging the battery, What’s the assurance that the panel is charging the battery

essegis:


You have them in your house already so leave the detective work for batman. Congratulations on the upgrade though.

lolz brother, tanx. i guess i was just stomped by the offer price when compared with what the actual market price
was supposed to be. plus the fact that all were brand new (in crates) as opposed to more common
fairly used telecoms batteries sold off as scrap by gsm base stations.

It will charge as long as d charger is ok

Bros I have a feeling you really got the batteries at a great deal that is way lower than the 130k a piece

ojesymsym:
This type of battery connection always confuses me when I see it. Each battery has 6 terminals, how does that work?
Do you have a drawing for it?

i see that essegis already answered you earlier.

in addition, you can always check the product data sheet for the correct battery terminal connection
sequence. where i had issues personally was how to connect both ends of the curve, since i had mine
in a double row fashion. for this i spent countless hours searching youtube videos of different types
of 2v battery connections without success until i eventually figured it out by myself.

Please what charger are you talking about?

sure I know my phone will charge when I connect the inverter to the battery,

what I want to know is will the solar panel charge the battery simultaneously as I used it for charging phone.

GeorgeD1:
as promised earlier, i have been on my 260ah 12pcs zenith batteries since 2012. it's been a remarkable
journey no doubt, especially given all the lament on here about lead acid batteries and their poor durability.
7 years and counting and my batteries seemed to just go on and on. at a point i almost became confused
as to why i was having such a nice time with lead acid while the general opinion was anything but pleasant.
maybe i was just plain lucky or maybe i was doing something right afterall...
the jury is still out on this...

Bros is it the same lead batteries vehicles use

Flooded batteries need to be equalized occasionally. I have had a set for about 6 years now, Trojan 6V in 48V configuration. Whenever I noticed a dip in the way my voltage holds up, I knew that it is time to do manual equalization. If your inverter and charge controller can not equalize, then you are in trouble.

ojesymsym:

Don't be confused, each side (made up of three terminals) is either positive or negative. But this is a massive capacity so only one terminal won't be enough to handle the current that can be drawn from it.

Notice how someone used a long bar on first battery to join the battery terminal. On second attached picture you can see that is a 48v system if you follow the connection, just assume each three cables coming from each battery is one to further simplify it.

Thanks for this info. How do you know an inverter that does equalization?

Sadly, it is not easy to determine unless it is clearly written on the carton. The tell tale signs will include inverters that can be programmed. If you can set the charging voltages (Bulk, Absorption, Float and Equalize), it probably can also equalize. The best way is to ask for people who may be using the kind of inverter you want to buy. I know most high-end inverters like Outback, Victron, Magnum, Schneider etc have equalization settings.

I guess you intend to type 480 watt-hour (12v 40 ah) battery and I'll wager it's those blue coloured lithium types. If I'm correct, you should get the functions of the four terminal wires correctly (2 input and 2 output) wires.

You also connected it directly to the 80 watts panel which isn't good for the battery. There should be a charge controller in between the two. You can get by with a small sized - maybe 10A to 20A - charge controller; one with bulk of 14.4v and float of 13.7v should be fine. If you also have a DC-DC buck controller with 14.4v output lying around, you can co-opt that too, better still if the buck controller has adjustable output voltage. The PWM charge controller should be able to provide you with info on your charging status. Some DC-DC buck controller, especially the ones with adjustable output voltage and current also come with voltmeter which you can read to guess your charging status.

About charging your phone, just get a cheapie car usb charger (shouldn't be more than 1k5), connect it to the output terminals of your battery and you're good to go. Of it's a PWM charge controller that you are able to lay your hands on, get ones with 5v usb ports included.

funshyboi:

nope. automobile batteries are different. they are called starting batteries while these ones used for renewables
are called deep cycle batteries but they are same lead acid even though there are now other battery types
including lithium.

ojeysky:


Certainly since it has adjustable settings

Thanks baba

Pls how effective is this battery below?
Price?

GeorgeD1:


i tend to agree with the dod bit as part of a wider range of factors that helped prolong the life of my zenith...

Boss, pls at what average C rate did you charge and discharge those zeniths with while they were in service?

adrusa:



YES! It actually has a lithium profile in the settings.

thanks boss

Trippledots:

I think he said they don't go below 12.5 per cell, that will keep SOC at 70% and above.

ojeysky:

Yeah i got that, but seeing he is using it for elongated periods, I'm curios as to the amps value during charging and discharging.

Well, you tried with the data, you posted, but a bit incomplete. Flooded batts require 14.5v to 15v charging voltage during absorb, and 23.8v during float. In bulk stage, it gradually ramps up from 13.1v, depending on how depleted the battery is.

Luminous inverters hv poor charging alogorithm, hv always said this, unless you have solar with good cc, i would not advice anyone to buy luminous inverter, worse still for flooded batts.

If 13.8v is the max voltage your inverter is sending out @ 12amps, then your battery are in an unhappy state, and would fail prematurely. C/10 charge rate implies a 200ah batt requires 20 to 25amps charging current to be happy

2ndly, periodic equalization, wch is simply sending higher voltage 15.1v to 15.5v every 2 to 3 months for 2 to 4hrs.you need an inverter or CC capable of doing this

I don't know why I keep stealing back glances at this Felicity lithium offerings knowing fully well that we've trashed out the overdeclared nominal capacities here. I pray greed will not take the better part of me.

Maybe it's because of my own supplier's price tag of 48/200 which is like 200k above the price tag of the Felicity's equivalent. I don already calculate what that 200k extra will add to my set up.

I tell people that one of the MOST IMPORTANT THING in inverter set up is BATTERY CHARGING.

If the felicity actual capacity is 150AH/48V and not 120AH and if the cells are new then I think it's a good deal at that price.
