Sorry about your loss, scammers have a penchant of putting up random pictures of people in their DP to seem genuine. Yet to see a scammer with the real picture on their DP. It's part of the low IQ "format". In other words, this image has a very likely chance of being a picture culled from net.

Thank you for dropping his s, though these dudes don't find it difficult to get another number to continue their scamming job. With all our NIN, BVN, National ID, etc scammers and kidnappers are still having a field day making calls with numbers that can't be traced.

Nigeria is a country that is unique in the sense that things here JUST DON'T WORK.

That is what I can't explain but one of these added over 50 counts and the other over 100 counts. The CC there is cycle count if I am correct.

I have no other explanation than it being in that heated vehicle cause since then their counting has been normal

What's the battery brand?

mctfopt:


I doubt storage temperature increases cycle count. Your display may have malfunctioned due to high temperature. The cycle count may likely be "audio" as in audio money

Ok. If it's a malfunction it probably would have repeated again cause it's over 6 months now and I have been checking it.
The battery has a breaker and a reset button and BMS shuts off after 48hrs of putting off the breaker. How that BMS did that extra counting just within that period is what I still don't know.

Maybe U can try to test and keep your pack locked in a car for 4 days during the dry season let's still check at that over 170 degrees if the count will be audio.

This is a section of Eve 280k datasheet.
U can only get 2500 cycles at 43°C from that sheet. I would drop this value to 40°C and 2000 cycles then assume worst case scenario.

If you can't maintain 23-25°C don't expect any 6000 cycles.

I know many won't agree with you, but they can't know more than the manufacturer anyway.

2500 cycles is expected at 43°C - 47°C.

Since the average weather in most part of Nigeria is 27°C - 40°C, we should expect (2700 - 4500 cycles); this result in 7-12 years if cycled daily.

hope you /know that the battery doesn't die after this 6k/4k/ or 2500 cycle count, rather its derated to 80% capacity...which is still a hell lot

Yes of course, was pointing to life cycle expectancy before derating to 70% / 80% based on brand of LifePo4 actually used.

Does lead acid die after cycle?

It dies faster than LifePo4

Super true. That 80% part is the real gee.
Imagine cycling sth for 8yrs only to degrade to just 80%. This is what tubular s dont know. In directly LifePO4 is almost for Life.
In Waec 80 to 100% is A1.

Lol. But how long do you really think a LiFePO4 battery will last before it gives up the ghost?

Pls I need a solar installer in Edo state

Mine is just 3 years one month ago.
Probably others here are 6yrs ...

Yeah, thats why i find it funny people putting so much emphasis on lifepo4 cycle life ..3k, 6k or 10k cycles...e no too get head.

My first lifepo4 pack will hit 3yrs in oct..and has about 178 cycles....so in 30yrs..will still be less than 2k cycles...so why shud i bother my head about whether its 3k or 6k or 20k cycles??

Any normal lifepo4 pack will easily do 15yrs.....and am sure within 10yrs...newer technology would hv even come out...that many may consider reselling their lifepo4 pack to upgrade

E be like ur battery de very large or u get abundance of nepa... Cause the cycle is quite low for the duration claimed.

In the village..just fridge..and lights, fans etc...then sumo once a week.totally offgrid.14kwh 48v.

Even if the cycle count was triple that..say 500cycles in 3yrs....thats still 12yrs minimum before degrading to 80%...even if you assume the minimum of say 2k cycles

It's quite sad.

Check your NIMC app, there are chances you have an unrecognized mobile number linked to your NIN.

Go to where they sell SIM by your street corner, they still sell ed SIM cards codedly.

I'm speaking from experience.

How can one measure number of cycles already on batteries?

solar system installer in Edo state here or any recommendations will be needed pls

Has anyone else observed the very low solar yields in South West states over the last 2 or 3 months or so? I have compared my July and August 2023 yields to July and August 2024 yields and this year has been clearly worse. It looks like Climate Change is very real and is creeping into our shores gradually.

Whats your installation plan like?..complete system fresh install or tshoot old install?
What area in edo state..may have 1 or 2 peeps to reco

Hello House; kindly assist.
I have an inverter setup with 2 Amaron quanta 200AH battery and 1.5kva luminous inverter that I have been using for about 18month now. I use nepa light to charge it.
It use to have backup light of about 6 - 10hours when I started using it. My major load is my 65inches TV and 3fans with bulbs.
Now, the setup get fully charge in less than 2hours and get drained in less than 2hours.
What could be the problem.

Kind of degradation you experience on Lead acid, it just continues to drop.. save your self the stress and get your self LFP packs.

Is the quanta battery a tubular type or normal dry cell?
