eginaP:
I currently drive a Camry 2007, and I intend to replace it with an SUV, A highlander 2009 or a Pilot 2011.

I need advise on which of the cars to go for, especially considering the Nigerian variables like availability of parts, terrible roads etc. also on the car side, I am also concerned about reliability, durability and resell value.

While buying a foreign used (tokunbo) will be my preferred option, financial constraint might push me towards a Nigeria used version, what is your thought on this too?

Incase you decide to go pilot I have a 2009 Pilot Ex-l that just arrived that I can sell to you for 5m.

I think he can buy external charger for it nah... Or will it not be sufficient?

Tommynaku:
This was exactly my thought. Buy and external charger to charge with grid, as well CC for the panels.
The next question will now be if the Luminous with CC and panels can charge the lithium battery bank

While optimal charging may be achieved with those external ingridents, there is the discharging part as well which will remain sub optimal but the BMS will always serve as last resort protection sha.

That said the cost of doing all that should already get him an hybrid inverter.

Tommynaku:
It’s a 24v bank. The challenge is that the luminous inverter is not hybrid
How to use the luminous inverter with Lithium Battery bank

Is that the luminous with parameters that is not editable? If yes then I don't think it will help much for optimal charging but it will charge just ensure your BMS hvd are conservative enough.... Get a better inverter once pepper rest sha

Amyfintech:
@Amdman.

I need Lexus Rx350 2008 and Acura Mdx 2012.

Am waiting..

Not Amdman but I have a 2012 MDX technology that newly arrived for 6m firm. Reachout if interested

Hello. How long will it take the car to get to me in Nigeria?

Depends but usually 2 to 3months max

Yup u should certainly use BMS if you want to take full advantage of the lifepo4 juice and so you can have a good sleep knowing that your 100s of thousands is safe but BMS is not what makes it perform infact it hinders it's performance (though in a good way)

NiyiOmoIyunade:
I do not think one can safely use LFP cells without a BMS especially the higher your cell count in series.

A lot of the no BMS gang are foreign offgriders/boondockers with small 12v systems - 4 cells in series with no BMS and the odds are in your favour, 16 cells in series and/or multiple packs and no BMS you are actually tempting fate.

Sadly most balancers/BMSs for lead acid do not work well enough - the accepted method for lead acid maintenance is 'controlled overcharge' - flooded users do this via regular equalization but most AGM and Gel users do not. It is best to do this 'controlled overcharge' at the single battery level as I have preached over and over and then you can actually see great gains in lead acid battery longevity and achieve the rated cycle life.

Again the specialised 12v chargers that can properly top off a 12v battery are not cheap so one has to balance everything out for his decision.

I do not also advice one use Lifepo4 without BMS but that does not mean one can't safely use it especially if one stays within certain charge and discharge rates. However the other point is that BMS is not what makes lifepo4 to perform but rather more of a safety feature that in some cases also limits lifepo4 performance

That said remember where all these round of talk started from, which was from a op asking about buying a used lead acid. The main point is that an LFP that is allowed to get to its voltage limits(up and down) is dead so it's easy to know if someone is selling such battery, but if its safely used for 4 months you can easily conclude that the cells are still almost up to capacity so long as it was bought new initially.

However for lead acid that is not dead, unless you conduct a capacity test or seller is truthful to provide you his usage history you can't be sure of the juice left in it after 4 months of usage, it's capacity may have "halfed" already.

NiyiOmoIyunade:
I am not sure that a newbie or first timer to renewable energy was able to take away that point or the fine nuances of context from your initial comments below. It is very important to spec clearly what you mean and any caveats when giving advice or support on a public forum.

I am the first to admit that LFP chemistry for example is vastly superior to lead acid especially for deep discharge applications.

The pertinent question is why does LFP appear to perform so much better? Beyond the superiority of the chemical/materials/electrolyte mix, a key part of LFP longevity is due to the work of the BMS and balance circuitry and use of optimal charge settings - implement a similar scheme for lead acid (ensure regular full charge per battery unit) and you will witness spectacular gains in longevity.

Okay Sir, put a BMS on lead acid to address SOC concern and achieve 3000cycles.... There are folks who run their lifepo4 without BMS (even though I don't do that personally) and still get the performance because you seem to want to tie it's performance to a BMS which can be misleading to newbie.

However, I refuse the temptation to enter into another round of lead acid/LFP talk Sir.

You're too arrogant. He's obviously referring to the lubricant.

You didn't see arrogance in below:

EgunMogaji2:
Read what I wrote and what you wrote then compare the two. Thanks.

EgunMogaji2:
Though I can’t compel you to do so but I’ll ask you to stay clear of my posts and not quote me in the future. I certainly intend to do likewise.

Egunmogagi looks like you woke up from the wrong side of the bed...I hope to remember your moniker in future. Sorry for commenting initially

Clean ride

EgunMogaji2:

Do the same to mine and compare with your response. Have a good day/week

NiyiOmoIyunade:
Lithium chemistries can deteriorate within a week if the current/last user did not maintain safe charge/discharge parameters.

Infact, if my understanding of the matter is correct, some Lithium chemistries suffer irreparable damage/degradation if discharged below a certain voltage just once whereas a lead acid battery very deep discharged can still have significant capacity restored if attended to on time.

I hope the 'Lithium is superior' pundits can focus on my core message which is below;

The advice to OP should be to find a reliable method of performing a health, capacity and unit balance test on whatever used battery pack he is being offered because a health assessment is par for the course when buying any used items.

That's absolutely correct with reference to voltage but the point I was making was in reference to SOC levels... You can be discharging lifepo4 up to 80% dept daily without worry after 4 months but same can't be said with lead acid but ofcourse if op can reliably verify the capacity all good.
