Ferdiwar:
I Sha don't trust the internal charging system of rechargeable fans.

Yeah, that's the biggest issue here, but an external charger would make it significantly more expensive I suppose.

Ideally we should be able to find a way to make the internal charging system work with lifepo4 even if it means not getting the battery to float.

I can actually run those stuff easily but I will have to run the connection myself physically.

Alternatively, if there is a 12v port then it will work. But a little bit pricy.. cells don cost.

May be you are not looking in the right place.

For 24v 280ah, there is an alibaba seller selling for 40USD and it's a detachable box (this saves you more money on shipping)
He sells the 48v for around 60USD

Your other option is to try local fabricators but they mostly struggle with finishing (talking from experience).

Why tf are the DIY boxes for Lifepo4 batteries so expensive. Any alternatives available locally ?

JJacko:
I stopped buying overpriced fixed voltage chargers tey tey.
Buck/Boost converters are cheaper and way more versatile. The 1200w below will realistically charge 24v @25A, 48v @15A e.t.c.
It has pin-out for fan, or you buy the 1500w/1800w models that have fan bundled.
Connection is not hard.

and what will you connect to the boost/buck converter to charge the battery at 24v 25a of which I know you cannot connect it to mains directly

Valto does not force anyone to buy from him, if you are not satisfied with his price, there are loads of other vendors to buy from. If you really care about diy people, why don't you bring in the cells yourself and build to sell it at knockdown prices. This trying to force him to sell at prices of manufactures who buy cells in thousands by batches is childish and inconsiderate. The only issue I will have with him is if his cells are not up to grade and he ignores customer's complaints which I believe is non existent up till date. Live and let live

You say?

It is possible to make 2 5kwh for circa 300k though.
100ah cells of many grade A cells are around 20USD
There is even a brand ANC that sells brand new 100ah for 17 USD (though this price was without m6 stud)
JK Smart BMS 4-8s 200A with 1A is around 33USD too.
Do the rough calculation and you will see that you can make a good 2.5kwh pack for 300k

dollarnaira:



You funny sha.
So you no longer bother about the cells used.
Who doesn't like cheap things? But a 2.5kwh for 375k that is supposed to worth say close to 550k? You cannot eat your cake and have it. You even said you don't care about the bms used that it depends on your output load. Wow!!! Congratulations ooo. Now Cworth is a DIY hmmm.

How did we get to this stage in the first place?
Back to your question, if a branded company in China can build 2.3kwh for 375k automatically I can build 4kwh for just 300k since the type of cell used doesn't matter. My joy and confidence is that you won't be bold enough to open it and complain. .

Cworth, Felicity etc are all DIYs right?

Most people are not interested in the Cells inside their packs.. are they working, surely LFP second life cells are surely working..

The debate, how do we ascertain we are not buying Grade B, C cells at Grade A prices,

Because of how are they going to know?

If have my share experiences and lets just leave this matter, but its annoying when people wake up what we are trying to die down.

How many of you mentioning USD as if it is Alaba Lagos in naira can order these to your door step from China? You think say na beans?

JJacko:
The one you bought for 103k is different. This one below I'm talking about is the more common older model.

Oh, okay

Cworth website claims the following:

3.8kwh 12v(GCL12300) has 3200 cycles @550,000 naira
3.8kwh 12v(LBT12300) has 6000 cycles @700,000 naira

I think that's transparent enough.
Obviously different cells quality. Still cheaper than your fav.
And na still LFP with 100A/150A BMS.

Plus this conversation is about more than Cworth. Ideally, na to get cells from China and couple as cheaply as possible. I fit use 30A BMS sef. This is DIY.

I order things from AliExpress but I don't have the capacity to order cells.

Do you have the fund to oder cells?

Try order just 1 piece of 50ah into Nigeria.

Get the point bro, to ship in cells is very very hard. You must have millions..

Not for personal use but commercial.


But you refuse to sell but desire to water others down. I know your type.

Don't hide behind, ship in cells and resell.
Not talking of personal usage. Shipping cost....

Gather the fund, ship from anywhere and resell as an individual. Waiting for the guys with millions .

I think you are getting this wrong. All these debate is about is that we should encourage people that wants to diy their battery. Let's talk more about how individuals can buy their cells if they can wait 3 months for delivery. Share of sellers in China people here have patronize. I don't think anyone is hating on anyone..

How does me agreeing that cells are getting cheaper equate to me watering others down?
And where did I refuse to sell when I have posted cells for sale here a few times?
