Boss Una no dey sell fully coupled 150AH or 230AH LFP for single 12 volt?

jonescosmo:
This is my present "Do it yourself" Setup.

My aim: The tubular Batteries will charge and backup during the day, while it will not last through the night it will signal low battery and the loads will be transfered to the LiFePo4 Inverter (you will not even notice the switching process) and everything is alright till sunrise when the batteries resumes charging again and the loop continues.

dollarnaira:

Unpack all and run a group of 3 sets.
Charge each set full(balance), allow dem to rest for few weeks to check for voltage drop then connect dem as 3s. You will enjoy it well.
The challenge is how to get a charger that can do 4.2v.

GloriousGbola:


its a real mess - microtransactions coming to actual hardware
it will get to the point where end users will start blocking the internet from their cars

i had read about hp printer nonsense, then i experienced it.

my printer refused to use a cartridge because the cartridge was older than a year. i had to overwrite the update, and block auto updating

this is the world we are going to.

I think @valto has smaller capacity you can reach him if he will do 4s. For me I have 8 units left and like to sell all 8 units at once. BMS is also available

So I introduced a small 20A Contactor which is engerized by the Inverter with the LiFePo4 Batteries but only when the dry contact on the Inverter With the Tubular batteries signals Low battery and closes.

My aim: The tubular Batteries will charge and backup during the day, while it will not last through the night it will signal low battery and the loads will be transfered to the LiFePo4 Inverter (you will not even notice the switching process) and everything is alright till sunrise when the batteries resumes charging again and the loop continues.

TechGeek777:


Boss try make you still couple 12v 230ah LFP with BMS, I believe say people dey here wey still dey look for such.

Tommynaku:

1. As I plan to also use grid to charge the bank, what capacity lithium charger do I need? Size and brand

2. Do I need 60A or 80A Charge Controller for 2.8kva /8kwh banks? And what good brand CC can you recommend?

Barezzi:
Trying to locate Niyi…

Valto:
maybe if there is another person that needs the same 12v 230ah. 4pcs of 230ah cells, it will cost atleast 380 to 400k, depending on material used, so will be extremely difficult to sell off.

bsideangel:
I need the same thing but I only have 350k will it be possible?

ceaser:


I think an ATS should be able to do this. Althoufh an ATS work S more with AC trigger.

However there is one model I came across that uses battery voltage as the trigger to change over from one DC battery pack to a second battery pack.

I'll go over my saved items to retrieve it.



How about if you invest in a non-expensive rechargeable spot welder? I think that will be safer. For sometime now, I ensured that every Li-ion 18650 projects I do are with spot welders.

Basic one with just LED indicator cost around 9k while a more advanced one with screen for information approaches 18k.



It will be another market for computer Village geeks.

Peeps will be like "I wan go update my ride with hacked software for computer Village"

Baba give us update na.

Eagba:

Sir please where can I find lifepo 4 battery to buy

FEGEITOK:


I have very busy on a very big project, but my workload has lightened, will give you full information this weekend.

So so sorry for the delay.

@toyeoye, I have updated this post with more information for you.

I am currently using Quanta Amaron SMF batteries.
I am currently using a Schneider Inverter 1.5KVA. I bought 2 of those.

After I bought the Quanta, I got to know of Deka and wished to get Deka next time.

That was because I was introduced to Lithium batteries, I am yet to do the research to determine which brand of Lithium battery to go for.

I hope that helps.

I currently don't have solar panels, I charge with the grid or my generator.

I plan to install solar panels before the month runs out.

I will be buying either 4 No. 300W or 2 No. 500W per inverter.

I picked Schneider because of the abundance of information on their website and that they had a directory of distributors/resellers in Nigeria.

If you need more information, ask and I will not hesitate to provide

toyeoye:



Awesome, I truly appreciate your time and support bro. I intend to setup 5.5kva although I currently have a 1kva setup for CCTV and floodlights only. I hope it's okay to "consult" you as I progress with the project.

Thanks again

Barezzi:
I got that picture from one of my contacts... I hope to attend the next one.

Regarding the emboldened;

You will notice that there are 2 inlets each for the positive and negative terminals for the PV array and battery(ies). If your cables are too large to enter one inlet at a time, you can split them.into the two provided inlets for each terminal. It works that way.

This present version of the PowMr Charge controllers will go out of production on or before first week of next year as it has now been replaced by an improved version.

This new version can accommodate more panels and the heat dissipation feature is more better.

I will have it in stock before the end of the year, and I am working to maintain the price point of the old/current version so that customers can at least have more value for their money.

Meanwhile, i recall delivering one unit of this current version to your acquaintance around Obanikoro on your behalf. Thanks for your patronage, sir. Please let me know when you need another unit and i could provide you with some discount.

Apart from the no fan and probably bigger connection port, please what's the additional feature of this model?
