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.

Well done boss, you mentioned earlier that you are having like 20k pcs of 18650 cells. Pls do you intend selling them?

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

chief how is the bread inverter since installation? What about the fan challenge.

I haven't installed it yet. I want to move out from my current place before installing.

If yours disturbed your neighborhood then it could disturb us here too.

Joke apart, it depends on individual difference. If u live in a quiet neighborhood you will understand better.

want to buy. Asking if the fan is loud, firman was my first choice but all purchase is online from ph, weighing my options. Are you using bread? If yes what's the fan sound like?

I have SMS the fan is not that loud like someone said it could be individual difference I started paying attention when I read some people here always talking about the fan. So mine could be loud but seems normal to me( individual difference) 😆

cutefy:
Can you share information about where u got your LiFePO4 and Liion cells? How much are?

Thanks

The lifepo4 has finished. Planning to ship about 2000 piece of lion cells if there are willing buyers.

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

No, because I don't have access to the cells.

How does one contact you, there isn't a contact details on your profile

I need help setting up a mini 1kva system with 18650 cells. Do 1kva sachet inverters have internal charge controllers. I would need recommendations

NO

dollarnaira:
NO

so which would you advice, a separate inverter/ charger system or a built-in inverter with charger unit, longetivity is a factor to be consider here, just a small unit that would be okay for at least 6 months, it should be cost efficient.

tetralogyfallot:
without precision, smartness, passion, brainwork, adept knowledge and carefully inculcating good SAFETY MEASURES when building a battery it can never be achieved. Note: I highlighted safety measure, it's super important when building any battery cos lithium ion does not forgive any bad connection or any bad battery building practice. Usage of good quality BMS can never be over emphasised. I either use good quality materials when building a battery or not even build at all. I recently worked on some tesla battery modules, the way the cells were super protected was astonishing.

So why have three of the battery boxes I recommended to my people explode, not once, not Twice!


Did you drop your quality or you got greedy?

Hybrid vs modular

It is about choice

Presently, am on a modular set up. I don't like to put all my eggs in a basket.

Usage and battery maintenance is very important too

I know but did three people use it badly?

officialfestus:
No, because I don't have access to the cells.

There is cells in the market na

SFTW:

It depends on two things…
1. The way they were made and
2. The way it is been charged and discharged
Some type of cells/ brand are quick to react to issues by Bursting into flames or gasing out

I'm about purchasing an 80kmah DC powerbank from wiremind, can someone recommend a 100w solar panel that can charge it from zero to full assuming peak sunlight of 4 hours daily, (brand new or used)

Did you mean 8000 mah ? Or 80000 mah ?
