Subscribed! Thank you for the video and instruction. I am trying to revitalize an Absolyte GP series 48 volt/2,000ah off grid battery bank and some of this information is spot on.
Pretty cool video. Like you, I've built batteries from raw cells, used repurposed cells for various needs, and also purchased complete LiFePO4 batteries. There is a place for each of these, for sure. Something you demonstrated, but didn't mention specifically, is the sense of satisfaction one can get from any kind of DIY project. This is particularly true when you build or repurpose a 2nd-life battery to fit a unique situation. Thanks for sharing your thoughts on all of this stuff.
Danke fürs Video 🤗👍
Hi Beene i thought this vid was brilliant. I like the honest history with lead acid batteries. I cant see the link for the battery seller but i am using my phone so will check pc later. I will be checking more of your vids. However like the young lady said slower with more detail less head in the way would be much appreciated. Generally great and thanks very much.
Maybe you should try a JK BMS with a 2A balancing current. I'm very satisfied with that. Especially when you have not very similar cells
Bad ass! Murica loves this video!
on the bench top power supplys if you use higher gauge wires directly to the connections you can get the full rated amps out of the unit even down to 3.6v if you wanted to parral top balance
This one has actually been able to provide its full 5a with the stock leads. Maybe they use the same leads for the 10a model hence it struggling ;).
I'm checking to see if you do the building for them and if you do how much would one of them or two of them cost
I can recommend the programmable Neey 4A balancer
Diy Lifepo4 new batteries are the best way to go for long term solar storage period. You can beat the price but at the cost of reduced life cycles. I found used Lifepo4 packs for $100kwh in the US but it's on the east coast and the shipping is very expensive to get to me on the Westcoast so buying raw cells from. China is a better price overall
Brother I think its a no brainer on eg4 ... U can't get that warranty diy I understand some thinks its cheaper to diy but really it isn't... Its just u get the satisfied that u built a battery .....The big bang for ur buck is a server rack batteries if ur wanting to run a house. Or diy ur own for fun.... Keep it up brother
I get it. They are about 1/3 more expensive which to many is enough to not bother with diy. And yeah, 5 year warranty!
If you build or buy quality, you can wipe your bum with all the warranties in the world 🌎.
You can literally build it for half the cost of the eg4.
I posted a link to the JBD app I use, you probably have to approve it. BTW have you noticed any appreciable difference between 1c, and 0.2c capacity tests? I have not, and thus just go for 1c test. I'm starting to think the whole 0.2c standard test is just leftover practice from lead acid.
Thanks! Don’t see it on my phone here but I’ll check next time I’m on the computer.
Fair point, haven’t paid mine to the .2c or not difference. Maybe I can get this one loaded down for a higher discharge test and check. Hmm how will I pull 11kw? Lol
Lead acid batt, if lightly used and properly charge, can last 10-12y but that’s more of the exception. Pb batt tend to last 6-9y under various “normal” use (automotive)
Yeah I think part of the problem is that good lead acid's can last a decade or more but people buy the golf cart or marine batteries and hope for the same. They are not the same and do not last anywhere near the 10 years hoped for. Since good lead acid is expensive, or you have to scrounge. Neither is a bad thing in itself but I really like the repeatability of lithium personally.
I have a lot of 1/0 aluminum wire rated for 125 amps should I use this or get copper? I'm building a pack that will have a 100 amp breaker and switch hooked to solar. Normal charge/discharge of current batteries are 40-50 amp max usually 20-35. I think I will use your design if you don't mind it looks like a pretty good one
I have debated some 4/0 Al so I could run my battery bank outside to my inverter inside. As long as you’re taking care of the typical aluminum issues like using oxide preventer it seems fair to me!
Honored if you decide to use my design. Thanks for watching!
Great video, thank you. Seems that you should have gotten a little bit more from cells that are 280ah
Oh these are 230ah cells. They performed right at spec!
@@BeeneEnergy okay, I thought they were two 200ah like the ones in the link you supplied
Good vid, Sub’d. Have you thought about recycling ur discharge via a charger/method to another set of discharged batteries, rather than just burning off the power to a heating element? Andy (Off Grid Garage Australia) has a Tesla, which is a cool way for dumping any extra power for his high Amp tests & still using/recycling the power for EV. Cheers
hello,sorry I’m using a translator. I just discovered you . Follow the diy or buy video from 03/31/2022.
I would like to know if your affiliate link is still active. To contact the seller.And in this case there is a standard sentence with details to bring. Thank you in advance Claude

Just not sure about 48V myself, when yoo got 20kWp on the roof .. sounds like one would end up with giant cables for insane amperage. Or so many inverters and all that it starts becoming a bit messy. Also, with 48V, the batteries might be cheap, but the bigger inverters usually cost a lot more than say a 10kWp Huawei HV system etc. And I wonder about losses. (PS: That doesn't mean I suggest people start to do DIY HV Systems .. :P for obvious reasons).
It’s true. Having a 500v battery sure cuts down on wiring.
But yeah I have vowed to not do a 500v house battery. Way too scared of it.
That's not true.. Your charge controller can take anywhere from 200v-500v from solar. That reduces amperage. The charge controller converts it to 48v for the battery. What other voltage would you use if not 48v? Anything else will require higher amperage cables.
Nice volbo
How many pounds you set the torque wrench 🔧?
I go for 40in lbs.
What are you down to now? I was looking recently and saw 300AH cells that work out to around 92$ per kWh.
Haven’t seen anything that cheap lately. Even straight from China before shipping’s costs. It’s odd but cell prices don’t seem to have changed much over the last three years, if anything they’ve gone up.
@@BeeneEnergyYeah cell cost has definitely gone flat/up. Trying to get near that $100/kWh is elusive.
With shipping? Doubtful
Does a balancer work for something as large as an Absolyte GP 48 volt battery bank?
Is that a large lead acid battery?
These days? Rack mount LifePo4 batteries are the way to go. Lot of good product entering the market with 5-14.4 Kwh plug and play units. Have their own bms, circuit breakers, communications, readouts, cell diagnostics and some are even heated. You cannot build anything for cheaper now.
They are the way to go for people who don't know how to build their own. It's alot more expensive than diy.
@@randybobandy9828 $1500 for 5kwh. Saves you about 300 doing DIY but you don't have a warranty.
@@davefroman4700 um.. You will save far more than $300 who told you that nonsense. Especially when you can build it far larger and not need redundant components. Warranty? Who cares. Anything that you would have to worry about a warranty won't matter since you can clearly fix it yourself. You can do this for $800 same size.
040122/1426h PST 🇺🇸 Hello Beene thank you for the demo. I too am a proponent of using B cells, as they have enough punch and lasts a long time. I also appreciate your sentiments regarding sellers of batteries. Of course, you know, that they do not manufacture those batteries but assemble parts bought from the East and sell them with funny trade names and profits.
I’m not too keen on ‘compressing’ the cells though, as I feel there’s no effect on doing that. I have similar cell arrangement for the past 4 years without ‘compression’ and cells have not bulged a bit. Perhaps this is because, settings in VICTRON PV charge controller is set to LiFePo4 as Absorption 14.20V / Float 13.50V / Storage 13.50V. JBD is my BMS and all the cells are balanced approximately @ 3.36V with delta of 0.002~3.
Battery voltage at rest is 13.45V 97%. (12.8V configuration with no external active balancer)
The above system has been running exactly like this for over 4 years. During winter, when shadow falls on the PV cells, I use VICTRON charger IP22 and IP 67 on ‘night mode’ condition. Charger shuts off during daylight.
Once again thanks for the presentation, which’s well designed and neat.
Thank you for the kind words!
My observation is that compressing or containing the cells can be effective in elongating their cycle life, which is hard to measure.
For me the bigger reason is to make sure the cells don’t rub against each other. Especially if a pack is used in an rv/motorhome. Last thing I need is an internal short!
Love your feedback on how it’s been going for four years. Long term testing is something I don’t have under my belt.
why don't you discharge with a grow watt?
To be honest, it wasn’t handy. Growatt was mounted on a box across the shop :).
or you could buy a seplos bms, which does have proper comms with inverter and other packs :)
That’s true, looks like the bms the rack mount batteries have been using commonly. Need to get a hold of one to see how it holds up to the jbd!
@@BeeneEnergy got them, work beautiful on my diy packs, they're even selling diy mason 280ah 16s enclosures which includes everything except the cells
@@BeeneEnergy check out Andy’s Off Grid Garage Australia for some great lab level info on Seplos BMS’s (& all solar & lifepo4 gear) he is doing right now, Seplos are a pacive balancer at 100mv or less, they need an active balancer to work properly on 100-300A cells.
JK BMS is the one u want, they are great. Good vid. Cheers from Australia
There is an .apk file for the Android app that's a developer version. way better, has the voltages on the dashboard
DIY 16cell 16kWh 48V EVE self imported from china Cells.
👍👍👍👍
Victron inverter.
Works great.
great video fyi i can barley hear you loud full blast
Uncontested and disputed. DIY is the most bang for the bucks.
Can plug and play beat the diy battery with case, bms, 300AH 48v 15khw+ capacity for $1600? for that price plug play will buy you 100AH battery for about 5kwh.
Are you sure you ask? absolutely positively because i already sourced them out ready to buy. Hint!!!! you are not going to find the components in the US and only in Asia. Then again there is only one country in the world that is leading for now and making LFP battery by the ton - China so now you know where i source to build my battery.
I am NO newbie in this solar thing. I had been doing for more than 5 years already starting out from scratch build and set up everything myself - battery, solar panel, inverter. The off grid 3kw inverter that runs the whole house and still works to this day. 100% off grid.
Nowadays there are abundant info. for diy in compare with years ago so what are u waiting for??????
Seriously NO body should do grid tie as off grid is becoming very feasible and affordable.
I went cold feet off grid and never regretted. 99% of the population won't do that!!!!!!!!

careful with that battery disconnect switch on a 51.2v battery... it's not rated for that voltage. not even the high quality Bluesea Systems ones are rated that high and that's a cheap knockoff!
You’re right that I should be careful. It is “rated” for a “48v” battery. But yeah without arc extinguishers which this in no way has it would fail turning off the battery under load. Though I rely on my BMS for that.
I didn’t mention that in the video though. So fair of you to call it out. Thank you!
WAYYYY too many ads.
bro fix you're audio!!!!!
You know, I would love to learn more about the things you do, but honestly, your videos aren't very beginner friendly. You throw out a lot of terms, I'm unfamiliar with; you don't explain the steps of what you're doing as you do it; you go too fast; and don't mute the noise from the power tools you are using, while you are talking... Makes it hard to understand. Also, that shot with your head in the way made it hard to see what you were doing. So, please, can you make this a little more user friendly, so an eccentric DIYer from Ohio can build her own solar system???
It’s true, this video while it showed most of the steps I go through wasn’t a great DIY resource. I’ll work on one that matches more what you’re looking for. I appreciate the feedback!
