na Valto make me never try any lifepo4 build, because he no they respond to my messages.
Abi na crime to inquire about prices before I make purchase?

ksmart027:
Try mrreed, he also sell cells

hmmm. it is cool , if u don't wish to buy from me,but u don't have to come online to discredit me . i reply all your messages as soon as i see them. u last chatted me on feb 23rd , and i replied promptly

below is the screenshot of our last chat ..all were replied immediately i see them!

officialfestus:
I'm not trying to discredit you, you've been replying my messages until February 23rd when I needed your service, you didn't reply, later had to settle for lithium-ion.

fashrola:
Can you build for someone with LifePo4 cells? 24v 4KW with Bluetooth BMS

Valto:
the post was misunderstood then.. i replied with prices , which u didn't reply , i greeted good morning the next day, u replied good evening the next day.. no further questions or inquiries was asked till this moment.

officialfestus:
you replied with prices January 2nd, on February 23rd, I wanted to finalize the deal with you when I wrote you, but unfortunately I got no response and the message was left unread.

How can one tell a genuine solar panel from substandard (brand new or used), how can I verify actual wattage?

Valto:
buy from accredited dealer like faouni or from @dollarnaira here and have a rest of mind

dollarnaira:
Thanks bro

Will be building a 24v 7s 4kw pack with 200A jk bms with 1A active balancing feature with these cells soon.

occfx:
How much did you buy JK BMS 200A and do you think it can run 1.5HP submersible pump.

Valto:
prices of my lifepo4 cells are as follows
gotion 15ah 3.2v =7500
Catl 23ah =11,500
gotion 50ah =24500
svolt 50ah =27k
GOTION 100ah=46k
REPT 142ah =59k
EVE 141ah =60k
Gotion 314ah (actual capacity 330ah and above )=99k
all are available in hundreds and thousands.

officialfestus:
$57
yes it can.

it's really a challenge but I still feel it's cheaper to build than to buy branded batteries, though it may also depnds on where n how u source your materials. Let's use 10Kwh battery as a case study. With your less than 1.5m u can build a very good quality 10kWh lithium pack, where can u get a branded battery for even 1.8m? The price of my good quality capacity tested 3.2Ah LG cells hovers around 1k downward depending on the quantity. So let's do the maths. U need just around 910pcs of cells, thats if u take the cells capacity as 3Ah to achieve 10Kwh which amounts to 910k, don't compromise on good quality bms, use a very good quality smart bms like JK, which price ranges between 150k to 200k depending on the capacity sha, some even come with upto 2A active balancers. Active balancer is a very important component in battery building i wonder why some battery builders ignore balancers, 5A active balancer is around 25k or even less depending on where u get them. The other consumables like nickel strips, voltage display meter, terminals and good casing may not even cost upto 100k. Totaling everything results to something less than 1.3m where u wan see good branded 10kWh lithium battery for that kain amount?

Setting up more power storage. 7S 28p with 2.5ah 18650 3.7v cells (67.5ah). These battery storage separators have made the job quite easy and stress free for me.

BangaRice:
You have a strong point but i have few objections to using 18650s specifically.
To achieve a higher AH with 18650s, it is always cumbersome and error prone to solder or spot weld too many cells.
A pack of 910 pieces of 18650s is quite large.
There are other Lithium ion form-factors with better AH like 21700, 26650, 26980, 4680, and more with some reaching up to 40AH capacity.
With 40AH capacity per cell the 4680 can be used to hit 10kwhr with just 60-70 cells.

Less work and logistic.
Also less stress in case you need to replace a few weakened cells(degraded IR), something 18650s are more prone to.

Where 18650s excell more is low end to mid range power needs of around 10whr to 1000whr. Above that 26650s are better and available in market.
