Send it back to warranty! Are you on our group (telegram), have you already asked there? If not join us the link is older posts. If you are not on the group i think we have a colegue with the same issue on the group.

Here you go some new info on this batteries. Be aware that this info is not present anywhere. Keep your batteries in the optimum range of temperature!

Found the issue the bms sends to the invertor that the recomanded current should be 5A. Insane! I have already contacted pytes. If you see slow charge and you know that you have power for charging more, go to console do login debug and after do pwrsys and see recomended current charge. After a...

I have another issue with the batteries. They are now charging around 0.8 Amps if i reset them for around 5 min i get 11 Amps or anything more then 0.8 but after a while they go back to that value. They have the same slow rate of charge even when charging from the grid

I would not recomend messing with the values!

i`ve created a telegram group for this batteries https://t.me/+WqsIOL-YF1k0YjE0

You will not get them at that price. They will redirect you to european sellers.

Hi Christian, sorry i did not publish anywhere,i`ve made it work but i had to leave that location and it got left there. When i will go back i will try to put the schematic here.

Have you reset the batteries after update? Let's talk on whatsupp

This is a small amount of graphs. If you are intrested on sommething in special i could have it! Look at charge and discharge. 1 and 2 are bougth together and 3 and 4 together.

Hi Christian, i`m using the rs232 with a ttl to usb module conected on tx and rx of esp8266. I`m reading the info from the master battery and sending all the info to my smart home. /* As info */ For the moment i`m still having the issues with the batteries, pytes (DLG) promised replacement but...

Great video. thnks!

$2,670.00 it`s a good price? So they leave china with a price of 1200 usd and double and more it`s a good deal? We are not here to see commercials!

I have made a small device with an esp8266 to read the data and send it to my SMH (SmartHome). I just finished the electronics and 80% of the codding. Similar to WifiShine. I will let you know when it`s done!

Do you have any servers? Do you have cacti installed? Should i just give you a python script that sends data to my servers? I need more info as it requires some linux/servers/scripts etc.. Or better should i create a general server where you guys cand send data?

@themizz can you graph your voltages and soc? i would have a point of refference! Have you messured the stored power of your batteries?

Thank you, i never hit enter to continue, only space, i never seen this part of the menu. Many many thanks!

All questions like this already answered in previous posts. Also a schematic for connections is available.

How can i not worry. It cycles my 2 good batteries. The current drawn from the is always almost double. Can you tell.me what bms it is? Can soc be adjusted? Do you know how i can list full config for the battery?

Hi guys i did a test over the weekend with the batteries. I did a discharge until the invertor triggered low voltage disconnect. As you can see from the images attached all batteries reached the same voltage but the SOC is different. I think the batteries in the second pack that arrived are a...

your dip switch`s are wrong? All your batteries are master? How does that work, if i seen corectly on all batteries the number 2 sw is up. That should be only on the master battery. How does your setting work for you? Thank you for the videos i just seen the video from david last night!

You need tham amps as well to start.

Can you please put a picture of the battery connections or schematic that would be even better and the number of cycles from each battery. Do you have one invertor or more? What type of invertor? Thank you so much!

Your`s seem to be even. I wrote a program to read the console and send the data to a database. Cacti get`s the data from there and graphs it. Wrote the templates for cacti as well. Everyone should ground evrething, but do not ground solar panels with batteries and invertor. I have different...

We did. I have 4 of them!

Today i moved just swapped the batteries at the factory`s request. I moved the battery 2 in place of battery 4 . And the issue moved with them, so it`s not a cable issue. I think that the batteries have different internal resistance. the change was done around 16:20. If any of you has any other...

Can we do a survey on how many batteries each of you have? Does any of you monitor the discharge and charge rates? I am talking to the factory about my issue and it seems that it needs further investigation. I think you should all check your batteries to see if they discharge and charge equaly...

125Amps

I have the same issue. What is your invertor/invertors and what is the model of battery packs?

I received the same update file as the one posted here today from the factory in china. I updated all my batteries. Main Soft version : SPBMS16SRP2110V1.1.3. Use at your own risk as they say!

Depends on your setup!

I hope this helps. I`m thinking that maybe the central bms it`s doing that. Or internal resitence on the first 2 batteries is lower!

The invertors are Growatt SPF 5000 ES, each inverter has it`s own cable and it`s limited to 50Amps. So most cand both get it`s 100Amps

I know thank you! Great note!

Yes same firmware. I will make a schematic tomorow! I tried charghing to 100% individiual and then put them back on all. The result is the same
