@Snart Azz did you find a replacement cells? I hope you can release the repair video. I'm looking for Pylontech BMS board so I can expand my storage with DIY pylontech module with cheap Chinese cells..but it seems impossible to find such bms sold online
@@smartazz thanks. I see it is a great BMS module..but I don't believe it can work (communicate) connected to other Pylontech batteries :/ If you can try it would be great tho
I would like to do the same thing too. but the seplos seller in china told me that the bms seplos cannot communicate with the pylontech batteries but only with another bms seplos
Is it not the case that when cells swell out like this they become highly unstable, in which case I hope they did not go through the postal system, and that you collected them in person. Plus you've made no attempt to protect yourself from what could of been a highpowered firework going off in your home, which would last for hours and no way of putting out!!!!! However luckerly all is well I don't think I would taken that risk, all I was looking to find out is what type of BMS does Pylontech battery Pack use?
Don’t worry, I have a fire bucket and sand at the ready, also I’m in the work shop not at home ;) I’ll be rebuilding the battery soon and I’ll have a close up of the BMS for you :)
They are pylontech US2000c. with a lux Lux inverter. Never used in anger. I was assured they were plug and play to my system. Plugged them in as master, went away for the weekend. All flat when I got back, I wasnt told there should have been a different comms cable.. I asked for help, but was told no.
Do you also have us2000b ? If yes put the B in the middle of the 2000c make a B sandwich lol. I believe the me3000sp doesn’t like the C batterys, and eBay are selling the very expensive new cables that are supposed to work.
@@lesmarsden8470 Iv not had any experience with the C batterys. Try asking here m.facebook.com/groups/2477195449252168/ Need details for a good response. Inverter model ect
Can you show how to recharge the whole unit? I've got 2 units that have completely discharged and refuse to play nice only. Ive just bought them and I'm furious. Cheers.
@@smartazz when I said cell I actually got it confused I meant battery pack I’ve currently got one charging at around 16v. I’m planning on charging all three then seeing if it will work. Battery was allowed to go flat for quite some time.. the green power light comes on but no SOC lights when you push the red button so have been unable to charge it hopefully this fixes it 🙏
@@smartazz the pouch is a RFE-F20 aka as a prismatic cell pouch or LiFePo4 cell pouch. This is what Pylontech use and strap together. My question was to help you, I already knew the answer. 😁😉👍🏻
@@pulsenation thank you, I’m very literal lol. I have spare cells for the rebuild video thank god as honestly finding the correct cells is hard. I’m currently charging the cells one by one to full and that’s takes a day for each cell, just about 10 more days to go (painfully slow)
I’d love to get my hands on more lol. So basically yes 48v battery charger will work, you need to test the voltage of the charger and make sure it’s set to the correct voltage. They are made up of 15 x 3.2v cells and each cell can charge up to 3.6v max (so 54v total in my case) Hopefully that helps :)
@@smartazz trying to source a board is proving difficult! Any leads appreciated. I will give it a clean but the corrosion looks pretty advance to my untrained eye. Thanks for the quick reply!
@@francisdoll1253 yes, I agree, but nobody offers a ready to use batery with this configuration. The main problem with single cell buy, will be the greater spread of internal resistance, that will cause bigger problems later.
i'm pleased to find your video. i wondered why the packs are relatively cheap, its because they dont use prismatic cells imho
Hi, congratulations on the repair. I need to replace some lithium cells on my pylontech battery. Where did you buy the cells?
I could only take cells from multiple broken Pylontech Battery’s . I also had to capacity test them.
@@smartazz sorry if I still disturb you. How many "ah" is each cell?
@@MrEretyco 25ah per single cell
Great video. I am looking for UP5000 cells. Where can I purchase them? Anyone know. Thanks.
@@ycmgxekwa I struggle to get them tbh. The only source is harvest them from faulty units and capacity test them.

No. I only have the c versions. Not a light between them.
I had a cable made but it was apparently too late. They need waking up, somi have been told.

Will do. Thanks.
Can you show how to recharge the whole unit? I've got 2 units that have completely discharged and refuse to play nice only. Ive just bought them and I'm furious. Cheers.
I can show how to charge each cell if you like 👍
Each cell max voltage 3.6v (it takes a long time to do it properly)
@@smartazz how do you charge each cell mate?
@@hondata05 I set my charger to 3.6v and started a long process.
@@smartazz when I said cell I actually got it confused I meant battery pack I’ve currently got one charging at around 16v. I’m planning on charging all three then seeing if it will work.

@@hondata05 just be careful as they can explode or burst into flames 🔥
When will we see the rebuild video, and do you know the make and model of the battery’s?
They are Pylontec own BATTERYS and you will struggle to get them brand new. I’m hoping to get some time next week to rebuild the battery. 🤞
@@smartazz the pouch is a RFE-F20 aka as a prismatic cell pouch or LiFePo4 cell pouch. This is what Pylontech use and strap together. My question was to help you, I already knew the answer. 😁😉👍🏻

I am being rebuffed (I could use a real swearvword) by the people I bought mine from. Would you look and assess mine for me?
What’s the make and model ? Can you make a video upload to TH-cam to show me?
What charger can you use on these batteries 48volt without taking them apart? I come across dead batteries at work. Normally a warranty claim.
I’d love to get my hands on more lol.
So basically yes 48v battery charger will work, you need to test the voltage of the charger and make sure it’s set to the correct voltage. They are made up of 15 x 3.2v cells and each cell can charge up to 3.6v max (so 54v total in my case)
Hopefully that helps :)
Can you replace a pylontech us3000c board that got water damaged
? Cells are fine
If you have got the replacement board I’ll replace it with pleasure.
Has anyone looked at it ?
Or cleaned it up?
@@smartazz trying to source a board is proving difficult! Any leads appreciated. I will give it a clean but the corrosion looks pretty advance to my untrained eye. Thanks for the quick reply!
@@seangrace6893 buy a us3000c with bad cells.
Where can I find the subsequent video
th-cam.com/video/HPkamTVMjz4/w-d-xo.html
This battery lithium ion or lithium ion pospate ???
Lifepo4
Can these battery be charged out ov a solar system I have a bms fail message
They will definitely need a BMS to charge them. But the answer to your question is Yes.
So is the bms in the batterys or the inverter I am trying to find out which unit is failing
Would I be correct in saying you are in the midlands
@@davidball2420 yes correct 😎
What would you charge to test two units as I am in the Midlands
Im in cv37
Pylontech is poor quality,i would never buy such a battery. 2 batterys in paralell (not a good idea) and 5 in series x 3 packs.It's a 15S battery.
What 48v battery is better???
@@johnmiller1355 A 16S 48v battery with single cells in series is far more better design as Pylontech with 15S2P
@@francisdoll1253 yes, I agree, but nobody offers a ready to use batery with this configuration. The main problem with single cell buy, will be the greater spread of internal resistance, that will cause bigger problems later.
