Okay noss, I've asked 2 shops that sells solar equipments they don't have it. I'll keep searching.

you can tell them to give big diode for solar.

The charger is 14.6v 10amp, What kind of diode can i use and where can I get it from please?

get a 10A rectifier diode.

I need Help!
How do I stop reverse current flow into charging brick in a common port BMS like this please? 🙏 🙏

get a diode to stop the reverse current, the diode is to be connected on the charger's output.

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?

it can be set to your preferred settings.

How good is these inverter?

for the brands of psw I've used, they're very reliable.

Update on my 1.5kw powerstation.
3s 1.5kw li-ion pack (100a bms and 1.2a balancer).
12v 3000w easun inverter with a continuous of 1500w.
Terminals.
Two 12x12 box.
Handle.
Voltmeter.
Buck converter.
14.6v 20A lifepo4 charger.

Note: battery was well balanced before the series connection. Now each serie reads 4.20v, 4.19v and 4.20v respectively.

The reason for the buck converter is to step-down the chargers voltage and Amps to 12.6V 10A. But I'll be doing 13v to hasten the charging process, since the battery pack has a bms installed to handle the voltage to prevent overcharging.

Penuelseun:
His battery pack is li-ion 3s with a maximum charge voltage of 12.6v, 14.6v is too much and will destroy his battery. He can step it down with a buck converter

using a buck converter to step down the voltage, reduces the Amp to 8 or 10A.

Can I can charge my 12v pack of 1.5kwh with this charger?

My appreciation to
@Dollarnaira
@Officialfestus
@Penuelseun
And the rest of others whom I could not mention. We got lots of smart talented youths in Nigeria. Only that we have clueless criminals who are masquerading as leaders.

Why are they not building solar panel plants or even encourage private investors to do that. Why are we not investing in our lithium deposits. We should be building batteries.

Abeg no mind my rants! It is easy to generate small electricity for household!

congratulations on your build.

Boss do your testing by yourself.those sellers do random test and that does not mean that you may not get some faulty ones among them(from experience) I have seen 0v among what was sent to me.

My recommendation is still these,very reliable.

I don't think is necessary, because I only build pack at my spare time.

saint2ace:
What's your estimated max amp draw from the battery (your BMS)? if more than 40a, i would suggest you add one more strip of nickel per 3v pack to help beef up the amp handling capacity of the pack. Just thinking aloud....

30 to 35A.

[quote author=Yemmyteespeed007 post=134538634][/quote]the strip is 0.15mmx8.
And also, what I intend to power with it isn't up to 300w.
