Got this exact problem.. how long did it take for you to charge it up? I tried charging it this way for a few hours and it didnt work, but i did charge it with jumper cables connected from my van battery to the bluetti battery cables. You mention 3 days it took, was that charging it for 3 days or?
I just watched your video today - impressive work !! My Bluetti is doing the same and won’t charge. Before I consider your process, I’d like to know how your Bluetti held up this year after doing this process. Thanks !!!
Thank you 🙂 My Bluetti has work flawlessly since we did that work on it. It charges and discharges like normal. We use it as our back up inside the cabin but it still gets used quite a bit.
This makes no sense to me. I have the ac200p powering everything in my van including a window ac in summer and diesel heater in winter, and my fridge/freezer. I read on the bluetti forums, an official post by bluetti that said if you use pass through charging, like I do all the time, I have to resync the bms to the batteries once every 30 days. To do this, I am supposed to run it down to 0 power where it shuts off, and then charge it fully back to 100%. I have been doing this with no issues for 9 months straight as that is how long I have been on the road so far. Toward the end of each month, I can see the variation between what the bms says the battery charge condition is, and what it really is. Ex: charging from solar with 600 watts input and the bms says 80% charge then, 5 minutes later, it stops charging as it says 100%. So, I know that should have taken an hour to do, not 5 minutes. Also, when I start using it at 100% charge, 5 mintes later it is down to 80% with a small load. Once I go through the proceedure as instructed by bluetti, then, all is well again until about a month or so later. My long point here is that you must have had your unit at 0 for a long time and it discharged down below what it takes to run the bms, just like you said. Otherwise I dont see how running it until it shuts off is bad as that is how you sync the bms IF running pass through like I do every day-charging from solar while discharging running my fridge, ac, etc. Excellent video on the teardown, thanks. I hope I never have to do that but, Im saving your video just in case.
I believe you are right about it shutting down if it is too cold. Outside our cabin got below zero and inside probably 15 or 20 while we were gone and that with the batteries drained below 40 volts caused the problem. We did try to warm up the batteries and it still would not charge.
@@sensiblesurvivalbushcraft6510 When you propel it to charge in the cold. You harm the batteries. I use a goal zero yeti 1250 during the cold climate. They are better in a cold climate. Good luck.
@@sensiblesurvivalbushcraft6510 You used a 12v charger? Just want to make sure. My unit has error codes 26, 42 and 43 and it's voltage is 36v right now so I'm assuming it's the battery that isn't at the correct voltage. Also at the screen it shows it's SOC at 100% which that's also wrong lol
my AC200P has went the same way a couple weeks ago , I keep trying the charger and solar but it just wont charge , this is the second one of the same model which lasted a year , I aint buying no more Bluetti stuff , the company will just ignore you !
This doesn't make sense to me. The company says you should bring it down to zero every 3 months and then charge it up from there. If every single unit broke down worldwide because people dropped it down to zero charge every single unit would stop working throughout the entire world
I won't buy from them again, my new one died completely and it wont charge at all now, i guess my fault for letting it get completely drain but there should be options to solve the issue, i might have to do the same, i have the small EB3A
I hear you. I am not going to buy anymore Bluetti's. I do have 2 of the EB3A's also they charge fast but only off of my solar generator. They will not charge from solar nor my gas generator. I most recently bought a Ecoflow Delta River 2 and it is great and charges fast from solar.
I am no longer buying any product from Bluetti. They will not respond not even to product under there warrantee. They will play a game with you until you give up. On my unit The AC 120 Volt output do not work. There is no power.
@@0055ford I will not buy anymore Bluetti products. I thought they would be a great company when I researched solar generators a couple years ago. They have failed miserably.
Mine just failed when most needed now wont charge with 740watts of solar going to it , now tryinga generstor with chsrger , i feel that having a pool filled with diesel and a generator is the way to go . This solar crap sucks dont work when needed
You said it was brought down to zero- how long did the unit sit at zero % ? Days? No power station should ever sit at zero percent. No power station should be charged below freezing - wether its Lithium ion or LIFEPO4.
We were out of town, I had turned it off and it somehow turned back on. I believe it trickled down on power having to lower its own lcd panel and inverter. It may have been at zero for 3 or 4 days at my guess. I don't believe it was below freezing when we charged it.
@billsboat4261 of course you can leave the solar plugged in - as long as the battery is 32F or above when charging - this is requirement of LIFEPO4 - that's why "heated" versions have been hitting the market the past year.
@@grindychum thanks … I think you meant 32Vs? I have the ACMax200 … So if it dropped below that and my solar was plugged in , is it severely damaged , or that’s just the reason my generator won’t charge? Or both? Thanks again, I’ll have to look into these heated batteries even though I’m never in cold weather on my sailboat where I have it.
this helped me a lot! thank you so much!
You're welcome, I am glad it helped.

Bluetti when confronted with California's Right to Repair Law said their Texas repair center would repair fàulty AC200Ps.

How long did you charge it for ?
Would love to know
I just received an ac180 and the circuit protector reset button on the side is completely missing.
The BMS shuts down when the battery is too cold to charge it. If you heat the battery would it start then?

@@byronmorris1594 I did not know that, thank you. I hope to not let it get that cold again. I will keep the Goal Zero Yeti in mind.
Mine shut down in the hot summer.
@@billsboat4261same
what else you have as alternative? nothing? it requires some compensations from consumer protection for the fault,
@@GordonSmith-x3w I mean consumer protection and trading standards
What kind of charger do you recommend getting? 12 V, 24 V, 48 V?
My understanding is that all of the portable solar generators are 12v. I may be wrong.
@@sensiblesurvivalbushcraft6510 You used a 12v charger? Just want to make sure. My unit has error codes 26, 42 and 43 and it's voltage is 36v right now so I'm assuming it's the battery that isn't at the correct voltage. Also at the screen it shows it's SOC at 100% which that's also wrong lol
False. Almost all of them are not. The ac200P is a 48v battery. Looking at the AC power supply proves it is not a 12v.
seem like one șingle solar panel can cause a problem, i suggest use more solar panels, have you tried getting additional panels
Actually I have 8 panels that are 100 watts each.
@@sensiblesurvivalbushcraft6510 so it is a fault. returning the product is difficult.
Why would having a solar panel attached drain it ? I think mine drained from leaving the dc phone chargers on , on the top of the generator.

@user-fg6lm3ef5o can you share a link where we can learn how it works, I would like to learn
@@user-fg6lm3ef5oYou talk absolute bollocks. These powerbanks aren't fit for purpose, you're defending a sub standard, expensive product.
Why are you charging below 32 degrees?
That's not good for lipo battery life.
You might have damaged your battery charging below freezing.

@@sensiblesurvivalbushcraft6510 the only way it could turn itself back on is if you had solar connected to it
