I use two bench power suppy as I linked in #42, one set to pack voltage (start at 55V) and one I rotate to the low cells till all cells are at 3.550 then I let the BMS do its job, I can get a pack balance in 24 hours, I think thats a better invesment than a chargverter

BMS does not need current to balance, passive balancer will bleed off current from the high cells, thats all that is happening I'm not sure how much balance current these BMS have but do some math, if the high cell is 5 ah (5000 mAh) fuller than the low cell and BMS is maybe 150 mA - 5000/150...

Ok looks like you can sit at 55v keep it there for as long as you can stand. correct Current doesnt "need" to be flowing. correct The only thing that matters is that the balancing is working. THIS! Does it balance without charging? Or does it stop as soon as its in float? Balance will continue...

Like Scrotus said, set the voltage and leave it for several days, balance current on these BMS is weak. you might be able to move up 0.1 volt every other day once you get the delta down in the 0.030 - 0.020 V range but until then nothing you can change will help. goal is to have balance on and...

Well, you can leave the setting as adjusted by SigSolar and cells will eventually balance. (You will be bald by then) lowering the current will not slow the charge as the runner cells will over voltage protect (OVP) because even 2 amps at 56.4 V will push runner cells up, lower charge voltage...

so on the 6000XP you are adjusting current at setting #6? or in monitor.eg4electronics.com at maintenance tab for charge settings, what is the "charge voltage (V)" right below "charge current limit(Adc) set to? this is where you can set voltage to stop from hitting "overvoltage protection" if...

Chris, how are you adjusting charge current?

here is the power supply I use to balance: any similar would work link to Amazon: https://a.co/d/dQqSJAF

firmware on his batteries start balance at 3.45 and continue to balance high cells till all cells fall below 3.45, password protected parameters not sure if EG4 will give up the password

As ScrousGB said, you need to see delta while charging at 3.48/cell and above. your cells are way out of balance and need to be held at balance voltage but below protection voltage for some time. The BMS in the Lifepower4 pack does not have much balance current, it took me a week of charging...

This was at end of the charge? cell delta at 53 volts is easy to get down, what is delta at 55 pack voltage? you are charging with a chargeverter? the cell voltage has to get high enuf to hit balance

SOC will be way out of wack till you get the cell delta down, I have 14 of the lifep04, in three batches, I just open them up and balance manually, all 14 are at 0.007 - 0.009 delta at 55.4 volts where I stop CV

CV setting on the 6000XP is too high (default is 56.4), I would leave it on lead and drop CV setting (#7) down till you don't get overvoltage protection and allow BMS to balance until cell deltas get lower, whats up with pack 1 total voltage is 1 volt less than the other 3?

Hello Brightside, thanks for picture. I was able to order 221 ohm resister and installed at R19. However, no love. when I energized the 8048 R19 heated up,smoked and the solder melted dropping the resister of the board so I'm guessing there is more to the Radian R19 story than I want to follow...

Hello @SparkyJJO Just wondering if you were able to see the part number for the resistor R19? My 8048 has the same issue and I was able to look at a 4048A power board to see R19 on that board is a 2210, not sure if I want to proceed based on that info but hey, the 8048 is not working now so...

I do not use the server for settings as the language is different for many parameters, I set all parameters at the local device and step through the user manual that came with each device, do you have the user manuals? available here...

I also have two Growatt, SPF 6000T and SPF 12000T I changed all settings locally when I powered up both units. I only use the Growatt server to monitor, The manual has a list of parameters and default settings, I believe a password is needed to change the setting via the server, and is kinda...

I have SA as well, just use the growatt site for info as you are correct on lack of configuration, loads just fine for me on mobile or desktop however SA much better

Cory has been most helpful with some issues i have had on SPF 12000K DVM MPV, have you tried logging in to the web portal? http://server-us.growatt.com/login what tim said about shine app is true for me also

I don't think you have enough battery for a 12000T, I have 2 Growatt, 6000T and 12000T. At first the 6000T was on 2 LifePower4 batteries and would fault when starting a heavy load, added another battery and no more problems. currently have 4 Lifepower4 on that system and starts 1.5 HP well pump...

Just sold my 2014 spark to upgrade to 2023 bolt. 45K solar powered miles and not one issue on the Spark 83 mile range when new was delivering 75 +/- miles when I sold it. might be kinda hard to find in NC since was a compliance car here in CA. effectively paid $11500 for the Spark after tax...

Hi John, each battery has a unique address set via dip switch and are then daisy chain together with short cat5 cables. laptop running BMS test software is connected and reads all battery data, up to 16 batteries

Unfortunately it only shows at most the past 24 hours unless I export data. funny the grass is always greener over the other side (Batrium)

if the OP does not have an old windows machine the mini-PC like you have is also a good route and victronconnect app will not see shunt via BT, 29 $ for VE.Direct to USB was reasonable to me

yeah sorry for incorrect link, I had the old laptop so 0$ and 29$ for ve.direct to usb, wifi covers my garage 200 ft and I'm able to see victron connect app from anywhere along with other interesting stuff in the garage:

you are correct, wrong link. correct link here: https://www.amazon.com/Victron-Energy-VE-Direct-USB-Cable/dp/B01LZ6WTLW/ref=sr_1_1?crid=25KO0AAMKQRH0&keywords=victron+ve.direct+cable&qid=1674613329&s=electronics&sprefix=victron+%2Celectronics%2C260&sr=1-1

I have Victron smart shunt in the garage 200 feet away connected via VE.bus to USB...

That is a great question, I have purchased 14 of the Lifepower batteries. installed at 3 different locations. I will have to research that aspect to see what went where. I will follow up with that next time I visit the remote locations, 6 batteries are located at my house others are at two...

lost another 0.1 % less then 3 weeks between drop

Currently full and balancing, SOC on all 4 batteries at 100%

I have not noticed SOC over 100%, I will observe today and see where it ends up

I'm not losing sleep over SOH from these, just makes me wonder why the difference? my packs get charged to balance voltage most every day (setting on SCC is 55.6 to absorb) that pack is usually less than 0.01 delta at full charge edit: currently 0.027 delta during balance

JLB, I will keep this thread updated, I also have two more packs to be added when I get a rack set up. I will update SOH on all 6 at that time. bruce

I have 4 of the EG4 lifepower and here is my observation over the last year: notice the different cycle count, two different purchases of 3 and 1 batteries. I am watching the 63 cycle battery drop 0.1 % every month. It was at 99.7 SOH when I put it in service. I would be happy to see 0.3 over...
