It seems this your PWM charge controller is different from regular ones. Does it allow setting of the charging voltage to align with voltage of the battery pack?

That PMW CC is an excellent PMW cc. Go for it, you'll enjoy it

dollarnaira:
You can't get the info you just looking at pix of scc. You actually test it physically or via recommendations.

Buy a cc with BSC... it is on jumia or powMr k-series. I have 3 brand new ones 20a each but to sell them they hard me. Buy the 20a or higher for this below:

Boss, thank you so much for your kind suggestion. I finally got the BSC4048 scc and it has been performing excellently. I took my time to read the manual, then I understand the settings better. With the present mode I'm using, it charges to 12.6v and stops flow of current. So perfect.
Meet my expectations
God bless you boss 🙏

officialfestus:
Who's in need of this CC?

I need am boss. Thanks in anticipation 😊🙏

Penuelseun:
use this

Okay boss. Thanks 🙏

Alright thanks. I'll check it out boss🙏

What of this pmw scc?

Is this pmw scc good for my 12v Li-ion battery??

Please guys, I need your inputs 🙏
I've been using the common small blue pmw solar charge controller, but I have to hook up a buck converter to it as advisedby some members here, just to monitor my li-ion battery voltage and ensure it doesn't go beyond 12.6. Because using my blue pmw solar charge controller, the lowest charge voltage is 12.7v, already above 12.6v.

Though beyond 12.6, the BMS will cut off charge in the long run, but I prefer it stops charging at 12.6.

Now what brings me here is that, I need advice on an affordable PMW solar charge controller that is effective, efficient and reliable for 12v Li-ion battery, such that I won't need buck converter to stabilise/stop charging my battery at 12.6v

okikigsm:
What size?

2a or any other available size

What size?

2a

Please I need 3s active balancer. Who's selling??

okikigsm:
Ok

I have contact in ibadan,ilorin,offa,ph.

Pick d best location for u .

Please drop your contact in Ilorin, i need battery presently 🙏

Please, I need a balancer 3s 12v...anyone selling here??

officialfestus:
aliexpress.

How do you make payment on aliexpress please?

dollarnaira:
Yes.
You must have been charging at 12.6 or slightly above.

Since the set up is without an active bal, it can easily derail wen u go above or too low. The lower part is my usual fear.

Point taken. Thanks boss

dollarnaira:
What is your configuration?
Error in sorting/ initial bal

Configuration is 3s 6p (is this what you're asking?)

It was well sorted boss, I've been using it since mid last year (June 2024)

Please guys, my 3s 12v battery setup with bms is presently having different voltage along each series . Please how can I balance it properly? I noticed because it stops changing at 12.3v...it's so obvious it's not hitting 12.6v no more. Then I proceed to check the voltage of each series, hence I noticed the irregularities.

Presently, I'm in Ilorin and I have been searching for active balancer 3s 1A, but I haven't gotten none till this moment.

So, is there a way I could balance it while waiting to get an active balancer?

Attached is a diagrammatic representation of the present voltage of each series Please help

Guys. Please i need your urgent help, how can i a dog (local dog) from pooing 💩 at a paticularly spot (not my dog but my neighbour's). It has really caused so much misunderstanding between my neighbour and I. The dog has no leash and moves around as it pleases. (I count their stubbornness as irresponsibility).
Please I want a permanent solution to chase the dog away from my spot.

Chat me up

Alright boss

Please guys, I need either of these usb dc module, who fit help me get abeg. I don find am for Ilorin tired 😫.

Valto:
@aliexpress, though i think i have 2pcs of the first one in the picture

Yeah boss, I saw it on aliexpress. But the present challenge is making payment on aliexpress. I'll chat you up boss. Thanks

AdexAyanfe:
Please who knows where I can get either of these modules? @dollarnaira @Valto @penuelseun

Anybody??

showafrica:
If you have 24v panel setup.. Just step it down to 29.4v the bms will handle the rest

Okay boss. Understood. Thanks

Someone asked if we can charge 12v li-ion battery bank directly through buck converter, bypassing solar charge controller .
I'm presently using this 9a buck converter. So please I'll like to know if it's safe to connect it directly to the battery, bypassing charge controller completely?? And will it function quite well?? 🤔

Obnoxious2001:
Do you discharge from your BMS or directly from your battery?

I have this set of batteries I assembled and I have been wondering which is best

I discharge through bms (recommended)...to safeguard your battery in the process of discharge and for balanced charging of each cell as well. Direct discharge isn't safe especially when dealing with battery pack. Well, more information will come in on this.

showafrica:
Interesting thread... We shall get there. I think Bulk converter can replace charge controller.

Really?
