QSO 230Ah Battery Capacity and Energy Test. Can the Chinese deliver? 🔋🪫

[@laurentsantaibambu7324]

Hi Andy and thanks again for this video, the battery capacity is correct and corresponds to the original data. , but honestly I am not convinced by this product. this battery was improperly prepared, improperly tested, before shipping. cell #16 pauses problems, and the cells are never balanced properly.But once again Thank you Andy for this Quality video. 😁👍

[@OffGridGarageAustralia]

I agree, they need to do more work on this battery, change a few things around and deliver them top balanced. I'll do some upgrades on this one soon...

[@gerhardlang2682]

Hello. It is such a great Thing that you publish such a lot of content. Thank you for this and I am always Happy to see a new Video from you. Heartly thanks from germany.

[@OffGridGarageAustralia]

Danke Dir, Gerhard.

[@camwood7600]

A better indication of whether the cells are high quality is do a higher discharge test.0.5c not 0.2. If it can't hold 3.2v under load and then snap back when load disconnected (after 1min) then probably b grade or lower. 0.2c isn't quite testing enough.

[@OffGridGarageAustralia]

0.2C is the standard test current for battery tests. But you're right, a higher C-rate could better show the cells quality. In solar installations such higher C-rates rarely occur though, so I thing 0.2C is fine for what people can expect from such a battery.

[@camwood7600]

@@OffGridGarageAustralia I agree that they say 0.2c is a standard metric, but the reality is at this level, lower quality cells aren't exposed and can appear to be of a higher quality. A grade eve 304 cells can still maintain cell voltage of 3.2 even when getting smashed at high c rates. I think it would be a great video to record cell voltages as you draw say 5000w and above. Push em until they break😁

[@cartercloutm]

​@@camwood7600 would it tell you anything about the long term prospects of owning such a battery? It's one of the big unknowns - as to whether the 6000 cycles / 80% capacity claim is just hot air and these lower-brand offerings will end up with unusable losses after only 2-3 years / 1000 cycles. If ability to cope under high c-rates correlated with degradation over time, then it would be a worthy test.

[@lua-nya]

Your amazement amuses us. Please keep up the good work.

[@OffGridGarageAustralia]

Thank you! Will do!

[@tonymartin3741]

You need to change the peukert exponent for the shunt when using Liepo4 batteries

[@FutureSystem738]

Excellent Andy. 👍 Interesting also that cell #3 was tied with one other (14 I think?) as the lowest voltages when the battery was full, and it was this cell #3 that stopped the discharge. Therefore as you mention at the end, I’m also guessing that with more balanced cells (hmmm, a better balance current) you may perhaps have gained a couple more amp hours from the battery. Like you, I’m not a fan of these milliamp balancing currents on cells of this size!

[@OffGridGarageAustralia]

I could measure 60mA balancing current with this BMS. That's not gonna work. I'll fix that in one of the next videos ;) Yeah, the whole battery was not very well balanced when delivered which is a shame. I would expect this to be perfectly top balanced before shipping. They could use a bunch of crocodile clamps and quickly connect an active balancer for a few hours which would do the job after assembling the battery.

[@wilvandendoel6782]

Hi Andy, on VRM DC input or output is not calculated as Feed-in or consumption, it mainly uses ve-bus data for the graphs, if you have grid feed in and connect a dc genset, you would see the grid usage go down. And go up with dc consumption. This is weird, but the reason is, it is not taking the bmv or smart shunt data into account, also dvcc is not working with external dc in or output. I already discussed this before with Victron but they are saying the vrm is designed this way. If you would use the output of the multiplus to feed your car, data would be correct.

[@OffGridGarageAustralia]

It all works perfectly fine when using the Smart Shunt or BMV. DC Power is then calculated as kWh and accumulates with the Multiplus output. Perfect. I don't know why the Lynx Shunt does not do this any more all of the sudden. It seems a big step backwards for me.

[@wilvandendoel6782]

Oké, I think then that the fact that I am using ess makes the difference, never tried it it in off grid mode, if you say it did work, then fine. May be check your battery monitor setting in the gx, may be its on automatic and has chosen a different device then before, don’t know your complete system , just a guess.

[@OffGridGarageAustralia]

@@wilvandendoel6782 THanks, I checked the settings in the remote console and the battery monitor is set to the Lynx Shunt. Still no DC Power. There was a thread about this in the community forum as well where I replied to: community.victronenergy.com/questions/101333/lynx-shunt-not-displaying-dc-consumption.html

[@larskiau2115]

Good morning Andy! Good Stuff as usual.. br Lars

[@OffGridGarageAustralia]

Thank you.

[@danielardelian2]

Another indication of cell quality is how well they stay in balance. Charge to 100%, do a top balance and then work the battery between 20% and 80% for a few days...maybe a week. Then charge it again to 100% and see if the cells are still balanced.

[@OffGridGarageAustralia]

Great test, thanks for your suggestion. That's more a test for cell matching rather than quality.

[@AnonymousScandinavia]

Amazing detailed test, which somehow reminded us of top-level engineers at NASA, being proactive in troubleshooting. Cudos to you Andy Spitzenklasse

Thanks a lot!

[@Eric_Tennant]

[@landonferguson7282]

Can you make a video about using the smart shunt in the power meter mode? I've only seen people use it in the battery meter mode.

[@keithcress1335]

I'm struggling to find a useful watt-hr / amp-hr tool for capacity testing 7 large batteries so I can parallel them into close-as-possible capacity pairs. I hadn't thought of using a Smart Shunt! What happens to the Smart Shunt data at the end when the BMS disables discharge? Does a Smart Shunt "remember" or do you have to quasi-panically monitor the end game?

[@OffGridGarageAustralia]

Yes, the Smart Shunt keeps all settings and results except the SOC.

[@BOGGarage]

Why are the lights on distributor red? mine are as well with heavy loads

[@OffGridGarageAustralia]

Means, the fuses are blown or not installed for this particular circuit of the Distributor. If this happens under heavy load, you have a high resistance with your fuses. Check that and measure the voltage drop across the fuses when under load.

[@zoe..d]

are you going to top balance it after putting some more reasonable values in the built in BMS and "trickle" the current in at the top to allow the top balancing to work? Would take ages with mV balancers though..... days? a week or more?

[@OffGridGarageAustralia]

Yes, next videos... 😉 I measured the balance current of this BMS and it seems to be only 50-60mA per cell. Yeah, that would take a loooooong time.

[@ciciedee5474]

As someone who has multiple bms's why not swap one in

[@OffGridGarageAustralia]

The BMS is not really the problem here (apart from the poor balancing). I think these BMS work not too bad actually. I would like to connect them all to the system so I can read cell voltages remotely. Working on it...

[@grahampahl7100]

Hi Andy. How does this compare to the Seplos/Mason batteries that you have. I'm looking at battery options for my off grid shed, would you reccomend this unit for starting out for the first time? What did the unit cost landed to you. Thank you again for sharing.

[@TrevorFraserAU]

Awesome one!

[@schaulustiger1]

Did anyone test the Shenzhen Basen active balancer already? An what about the JK smart balancer? @ Andy, which one is the best? My battery is close to be ready and usable but i can´t decide about the balancer because of all your nice info and tests.

[@OffGridGarageAustralia]

First of all, do you need an additional balancer at all? Do a top balancing and use the battery for a few times before fully recharging. Check the balance again. What BMS do you use at the moment?

[@schaulustiger1]

I have an Daly Smart BMS 200A. The battery is not in use in the moment. I wait since a close year of a replacement from Basen, because there was 2 cells in my delivery with over 50mohm IR. Annoying enough but anyway... so you think I need just to check first how it is working and how the deviation will be before think about the "right" balancer?

[@00-Chris]

Hi from Berlin! Kann man hier auch Fragen in Deutsch stellen? But anyway, I need a 24V 100Ah battery - I thought about putting two 12v 100ah in series. Do I need something like the Victron battery balencer to keep the two balenced? And do I need a 100A or a 200A BMS in each 100Ah battery if I want to run a 2560W inverter? Does it make any sense to get a BMS with overhead? I would really appreciate if you answer my questions.

[@markwilliams5654]

Yer it's all about the voltage sag under load and internal resistance

[@rainerflesch8148]

Hi Andy, don’t u think you should set the Peukert to the right value for Lifepo to get a proper result?

[@kevinmills5293]

Only if you want the percentage value to be accurate.

[@OffGridGarageAustralia]

I only use it as a Coulomb counter, so no settings really matter in this case.

[@jasonbailey6788]

Hi Andy, I've got a Daly 250 bms ( yes yes I know... but I got it before I watched your videos 🤣🤣🤣) how can I connect it to my growatt es 5000, having problems connecting them 🤬🤬🤬, can you help please 👍

[@OffGridGarageAustralia]

Did you order the BMS with CAN/RS485 communication? There should be some sort of adapter cable... Not sure what communication the Growatt needs. It's best to contact Daly for that sort of stuff. I'm not across all BMS and inverters combinations. Just too many...

[@markwilliams5654]

Get a large metal bar and direct short a 280ah cell and see what it can discharge the bar will get hot but be a good test and then measure voltage sag

Many options for Canada, just like the US. I've bought from Amazon, Volts energies, Canbat, etc... just buy when it's on sale as they often mark up Victron more than it's worth.

No, sorry... not yet...

[@SeanMoore2008]

.. the battery wasn't full, some of the cells might have been quite close to full ...

[@OffGridGarageAustralia]

That's how the battery was delivered and you have seen the BMS shutting off. So, that was as full as it gets.

[@BrazzaB1]

Good price for batteries. Wonder what the shipping is for the UK 🤔

[@typxxilps]

have you checked the right prices or do you believe in the fake prices ? You need to use the lead price which is 2700 and not 1200 - quite a difference and that gets even bigger once you ask for a ddp price to your door which is the only price you should ever accept just to avoid all the risks of fees at delivery. I doubt that the price is still that good as this is just the test result of the battery delivered to andy cause you might get a completely different one, not the EVE LF230K with 6000 cycles as mentioned in the product description (the cycles).

[@BrazzaB1]

@@typxxilps If the capacity is OK - Andy didn't top balance them before test. It's about $3400 delivered for the 300Ah 48v battery

@@davedubreuil I ordered said power supply from them. I received the 30V 20A version. Since then the seller was taking any effort to frustrate the process of getting my money back and returning the power supply. Alie Express granted me to return the power supply, but after a long struggle to get the right address, which needed involvement of Alie Express again, the seller did everything not to cooperate, ending in a package which I did send getting eliminated by UPS because the seller didn't met the deadline for contacting his local UPS office for assisting the clearance procedure. The conversation with the seller contained a slurry of delay tactics and insane answers driving me crazy. I still have to wait if I get my money back by involvement of Alie Express, as the last state of affairs is that Alie Express instructed the seller to contact the local UPS office, which will not work for explained reason. ARGHHHH!!!!! Needless to say I stayed polite , while from the beginning I felt an knew which direction things were going and what the seller tried to pull off.
