Hi Clifton, Were you able to test unbalanced setup by any chance yet? Any recent updates or new experiences? Cheers

Once I do that, BMS is no longer allowing me to change any parameters. So it comes by default set to 280 and if I change it to 304 (my cells are 304) after that no parameters can be changed.

You gotta hate yourself at the end if you give them your money. I don't care about $$$ it was a test / proof of concept for us but wasted time we will never get back.

We need a new thread created, something as #SeplosMustGo or Beware Seplos... I had more "troubleshooting" with Alan and he is really the evil one too. If he doesn't like you, he will send you wrong files, wrong info, waste your time (I suspect he gets off on it) without fixing anything and to...

This is by design, 1st pack (0) is not reachable after you set dip to 5 on it. It was confirmed by seplos. They suck...

Same experience here, Adam from seplos is an arrogant a$$, doesn't follow through on his promises, he will tell you whatever you want to hear but once he takes your money attitude changes right away. Alan from support is almost useless and a waste of time for the most parts. English translation...

Hello Fellows, I am looking for a configuration for a Seplos BMS which would allow me to store my battery banks at 50 to 60% SoC during the time when I am away. I have two batteries connected using Pylon protocol to an LV6548 inverter with a solar array. BMS has option where I can change bulk...

And I was ready to shave my head... I've been trying to get Pylontech comm to work between Seplos and LV6548 and so far all I got was F61 error code. Does anyone know if there is a fix that have been released yet? Cheers, A

Hi there, were you able to get a 112.14 FW? I would like to flash back to the original version but I can't find it anywhere. Would really appreciate if someone could share 112.14. Thanks! A

https://diysolarforum.com/threads/experience-purchasing-eve304ah-cells-from-amy-peng-shenzhen-qishou-technology.34587/#post-525141 In case you wondered you did good and got lucky!

I tested my cells at work and none of them discharged at 1C rate. Voltage drops and they become unstable. All of these are factory rejects that were suppose to be marked B but probably were sold off to Alibaba vendors at cost. Amy was nice and gave me $800 discount but I still ended up with...

Anyone?

Their manual is very specific on using balanced configuration on both controllers or whatever configuration but only on one...

Hello Everyone, Does anyone know if it is possible to connect 2 strings(without issues) of solar panels in the following configuration: 5S2P on one MPPT controller and 5S only on the second one to the LV6548 inverter? Manual says the following: I would use 15 panels...

Hello Everyone, Does anyone know if it is possible to connect 2 strings(without issues) of solar panels in the following configuration: 5S2P on one MPPT controller and 5S only on the second one to the LV6548 inverter? Manual says the following: I would use 15 panels (CS1H-340MS) arranged in...

Got my cells. Not impressed. Amy is nice to deal with but cells are swollen somewhat and some pull below capacity. They don't have the green and yellow spreadsheet and you have to ask her specifically to see if they even have some cells that came with it. I can't test for now 1C discharge rate...

Hello there, How do you control the temp? Do you use a thermostat? Is there a thermal protection in case something goes wrong? Thanks! A

Hi Dzl, What if I have two cells side by side and I have to compress 2 rows at the same time (16S in 2 row arrangement) What force should I use then? Thanks, A

Quick question for lucky owners of EVE 304Ah cells. I am going to setup in a 16S configuration as per below image and as far as I can tell the circled bus-bar is a different size. Could someone please confirm which size busbar I would need? Link to Ali would be appreciated. Thanks, A

Sweet, 1kOhm pull down should be easy. (It seems as they have modified the BMS once again, added Heat Function and new connectors) As always a few questions if you don't mind ;) 1. Which PINs are used with the pull-down R on LCD Header? 2. Are those Micro JST GH 1.25mm 3P, 6P & 7P type...

I guess, if you connect it to Rpi but if you connect it to another rs485 port (on an inverter for example) each bms would need to advertise an address as per attached protocol description. Does attached protocol description resemble anything JK BMS uses? I hope it should be universal or very...

Nice diagram! If I have two battery banks with 2 bms, is there an adapter where I can set an address so I can communicate with both bms via rs485?

I thought he was Martijn was after rs485 output as Victron Cerbo doesn't seem to have any USB ports... Anyways, I was thinking of using this: https://www.aliexpress.com/item/32857507366.html To convert BMS TTL to RS485 and then connect RS485 output to RS485 port on the LV6548 inverter...

Use something like this (with header and terminal block): https://www.aliexpress.com/item/32857507366.html If you don't need those, this one is even cheaper: https://www.aliexpress.com/item/32707755990.html Both should do 3.3 or 5 VCC. @upnorthandpersonal could maybe tell us if BMS TTL is...

Got it, thanks!

Sweet, Thanks! I have seen that Hankzor was also selling a RS485 module? (Pic attached below) Do you know what is it for and if I need it with the new rev boards? What you described previously looks as a half duplex RS485 interface header so what is this adapter for then? I can also see 2...

Serial is fun for sure! Nice code, will have to try it once I get my hardware. You seem like a right person to ask, do you know what is the jk bms pinout on rs485 port and same on an LV6548 inverter by any chance? I heard that JK BMS is talking Pylontech protocol and it should interoperate with...

Since we don't need a lot of heat produced inside an insulated box, how about using using a few 30 watts resistors to produce heat inside the enclosure? I can lookup an adjustable thermostat and we could size R according to your battery voltage so it barely keeps it above freezing?

Good Morning Folks, Could someone share their experience purchasing cells from Amy Peng @ Shenzhen Qishou Technology? She quoted me EVE 304AH $118/pcs. promising Brand New Grade A cells with no swelling blah blah... I saw Andy from the Off Grid Garage purchasing from her and he was happy...

Your professionalism is showing and I am sure we are going to have many conversation in a near future ;) I really like how you got the batteries inside a metal enclosure as you never know what can go wrong with so much of stored energy... Few questions if you don't mind: - When compressing the...

Thank You Everyone, very informative answers! Will follow your advice and stick with 304s then. Appreciate your insight! A

Good Morning Builders and Tinkerers! I would like to resurrect some old threads about 500 Ah batteries (pics below) from Ali @ Unit price: 175USD now. Has anyone tried these before? https://www.alibaba.com/product-detail/for-solar-system-energy-storage-car_1600352354245.html Thank You All! A

My dream install ;) Outstanding quality work! I am in a process of building exactly the same setup, waiting for batteries and the inverter to arrive... I have a question about Ground bonding to Neutral at the generator requirement and Ground bonding to Neutral at your main AC output panel and...
