So I’m always looking at the unanswered threads... seeing if there are any that with my limited knowledge I might be able to help. There are 6 pages of them... is it possible that between us we could try and answer all of them... it must be disheartening to get zero replies...

YouTube is all about the drama unfortunately... the algorithm demands it... no drama ..no clicks.. makes for a very divisive society... that’s why I like this forum.. full of good people and good info..?

I think I’d be more concerned if you’d found a bunch of 18650s tbh..

It would be a great affirmation of the forum if no threads go unanswered...

Best thing to do is search the forum... if you can’t find the answers there, then start a thread and see what happens.. otherwise I’m all ears...?

Do they reach eg 3.6v or 3.65v...? Didn’t an earlier comment mention that you may have one cell triggering the bms cutoff ... while the others are still undercharged... just trying to help..

I really don’t want that image imprinted in my memory.. but it’s too late...the butthole is covered by underwear for good reasons..

Absolutely... I might check out the specs and see what Bluetti state.. ?.. don’t want any smoke...

Not sure “mppt module “ exists ... only in the very confused mind of the person asking the question... this is a Bluetti I think being questioned.. the answer is basically saying you can hook up panels to the Bluetti without the need for an external “ mppt module”..( charge controller)...

“Let them cook for a few days”... ?

That’s a good approach... it’s not possible to help every thread... my knowledge is limited... so I’m not much use lol...

Glad you posted this... I think a sign saying SAFETY...SAFETY...SAFETY should be hung up in our workshops,garages,basements etc..thanks for reminding me ..?

You mentioned pulling 300a... battery hookup have some 300a ... good to have some wriggle room... they are made by Xiaoxiang.. which I believe is JK... https://batteryhookup.com/products/7s-21s-24v-75v-300a-lithium-ion-bms?variant=43085312884898 160ma balancing... so not ideal but heavy duty...

Just about to head into the jungle.. see if I can come up with an answer or two that won’t endanger anybody’s life... thanks for the reminder SeaGal..

Crowz you are def my go to statistics man from here on in...

Looks like a good setup... hope it all goes well for you.. good luck..!

Two panels in series = 80v @ 10a + Two panels in series = 80v @ 10a = 80v @ 20a Somebody please check this ?

This is a video about your model of meter...

So I think you’re right... if fully charged bay sits at 13.8 ... maybe set v to 13.7v and at 13.8 will show 100% soc... I’m no expert .. but using these threads to learn as well..

Build it strong... never know when a bad wind is going to whip up put of nowhere..

If it was me... I would stop using the system... take the battery apart... test the cells.. see if you have any duds, look at the bms.. get a spare bms of similar spec.. rebuild the battery with the new bms.. see how it performs..obviously I can’t tell you to do that because I’m not qualified...

Merry Christmas..?

Top shelf stuff... over 18s only..

Good to see it up and running ... Merry Xmas and hopefully a great 2024 for all of us...

It may just be that the recycling logo says Li ion... and they are in fact Lifepo4...

I think you might need to...Santa tells me you’ve been very good all year... and that the elves have been working all year on your pressies... don’t forget Rudolph’s carrots ?..?

Group effort.?

Of course we want you on the forum... and definitely don’t want to dissuade you from anything.. we’re just talking shite about tools .. doesn’t detract from the brilliance of what you can offer.. this thread has been based on taking a problem.. applying a solution.. but always with a sense of...

The bms PCB is something I’ve not seen before... beats all the wire spaghetti creeping around... I’d imagine it’s cheap to manufacture..mind you everything is in China.. Good timing... Red Sea looks like it’s being avoided by China now... nightmare for shipping..?

Eye spy Milwaukee... @Crowz would def approve..
