Hi everyone. I have been building my home battery setup for a while but recently took delivery of my EASUN Hybrid inverter / charger. After working fine it has developed a fault. The code is 04, BUS FAILURE, whatever that means? I would appreciate getting an explanation of what a BUS FAILURE...

OK. So just to reconfirm, should i be setting the low side at 2.8v or 3.4/3.5v? and the upper to 4.2v? I don't intend on hammering the packs as when I calculated it was a good range of 42% usage overnight as a maximum and 15/17% as an average. I have also been offered another set from the same...

You're right on the scarcity of the info on theses cells :) Thats why I hoped someone else had done something with these, but no one seems to have attempted it yet. Probably because of the fact you cant have each cell separately easily. I will look into standard test details online but I cannot...

Hi everyone. I am currently reconfiguring a battery pack from a 2019 Hyundai ioniq. These use the LG NCM622 polymer pouch cells. I have struggled with this build getting going but am now headed in the right direction and am at a point that i need to set up a test rig to see how the hybrid...

Ok. Apologies. I hadn't realised. If I get a chance I will upload some pictures of them in my workshop tonight. Thanks David

Hi Everyone. I have 7 Daly 13s 100 amp 48v bms's for sale. I had bought them on the advice of the rep in China but not only did i get hammered on the import duty but they wouldnt work on my setup. So I have had to replace them all (7 units) I have them in a box and are brand new except 1...

Well, thanks to various people I have confirmed that I cannot use the 13s bms's. I have reordered 7 12s bms's. I now will try to get some of my costs back by selling the 7 13s 100amp 48v. I will have a look and see if I can post them on here for sale maybe. DM me if anyone interested. Many...

Thanks Floyd. The bms wont work. So now I have 7 x 100 amp 48v bms's redundant. I have had to order the 12s versions but thanks very much for taking the time to advise. David

Hi all, I have got the BMS's from China ( and the hybrid inverter charger has arrived ) and have attached them as per what I've found on the internet. I have received 13s bms's when i need 12s bms's. I have scoured the internet to find out whether or not ive just been had for £600 as i will...

I have researched to find a way of splitting them but I cant find a way. They have not become so mainstream as the old 18650's so that is an advantage cost wise still. I am going to leave them as they are with the exception of the 2 x 72v packs. I can get a bms without an issue but...

Depends on the year but i would expect we are facing the same issues KRAWCU. I have had some info but with everyone saying i'm going to set fire to my house on various forums has put me back into research. I understand the issues around charging etc but as i have each pack as separates ( 48v...

Thanks Oberfail. I don't mind what app to use. Whatever you suggest. At least I may be able to show you in more detail because I can't believe it's this difficult to split the cells. Let me know what I need to do and I'll get on it.

Am so nervous about stripping this to make the packs because I cannot find ANY information on how to safely deal with them. I need to charge the packs, bms etc. No idea what to do or how to do it. Till I can figure that out I can't do much unfortunately. Thanks for the advice so far 🙂

The putty like paste must be for effective heat transfer but I still can't get this pack broken down any further. The sections still seem solid so there must be another lock somewhere I haven't come across yet. Bloody tedious....

Ok, not alot further today as too much on. But at least I understand how these are held together and am hopeful through this week I will spend a little time each day working on them. Any more thoughts please feel free to write as I will take any and all advice. Many thanks for your help so far...

Ok. I'll see how they come apart. I couldn't find any videos with any info on how these ends come away. If I can get any of these end caps off I will try to get the heat gun in to split each pack apart and will take some pics for here 😁

Thanks floyd. I'll have a look tomorrow and try on the smaller pack first. I have a heat gun but does anyone think that I need to remove the plastic ends where I guess the pouch connections to the bms would be? Cheers, David

Right. That makes sense, 40 to 80% for longer lasting life. But that was why I didn't go for a forklift battery because that was only 40% of usable power..... Would like to get 10 years out of them if I can. Going to take a hammering in winter and no use in the summer. If I can figure this out...

Thank you OffGridInTheCity. In 1 response I've got more specific info than my trawling of the web. 3 of the packs are already configured to 48v but I am not sure about capacity but as a whole 336 volts with a total pack capacity of 44kw of which the manufacturer states 39kw usable? I guess for...
