Globalists dreams for years. Gates has been talking it up in 2020. Would take too long to explain and is off topic. But it is coming - with the 5G rollout. One step at a time.

The entire purpose was to find a suitable battery/cell balancer. Exactly what function will the additional BMS do (FOR OFF GRID SOLAR) that the inverter and charge controller fail to do? Are the cynics living with off grid solar? Or just burying their nose in propaganda? The main function of...

Big Battery rep said any side is OK except for side with voltage read out and SB150 connector. That is a nice feature.

Will also consistently states the inverter and charge controller should manage charging and cut off parameters. If I was Ingsoc or an Ingsoc contractor (cough) I would not hesitate to employ the redundancy of course. Saving $100/battery would simply be beneath my dignity!

Appears these will work - $8 for qty. 10: https://www.amazon.com/gp/product/B01EVINO72/ref=ox_sc_act_title_1?smid=A2R05BPCF3X8F9&psc=1 Still - it is really stupid for the cell balancers to have no option for a wiring harness. Their ratings are getting nuked by those with no interest in making...

The above 8S capable cell balancer has a grotesque achilles heel. No hiring harness is included. No option for a wiring harness is found. Just suggestions to "make your own". This is ridiculously stupid.

I will be managing the batteries with the Outback inverter and charger. Looking for cell balancing - hence the thread title. Appears that up to 7S cell balancing may be "somewhat standard". This A123 battery requires an 8S cell balancer. So we are, once again, back to previously linked cell...

Hence the title of the thread - regarding cell balancing.

This looks familiar, doesn't Will use this satisfactorily? https://www.amazon.com/ISDT-Battery-Meter%EF%BC%8CLCD-Capacity-Balancer/dp/B07797N9BG/ref=sr_1_3?crid=2TH3XBC55N1E5&dchild=1&keywords=cell%2Bbalancer%2Blifepo4&qid=1600734908&sprefix=cell%2Bbalancer%2Caps%2C234&sr=8-3&th=1

Bought 4 of the A123 24V batteries that the board has been abuzz about. Will use my Outback inverter and charge controller for general battery management. But I still need a couple "good enough" 24V cell balancers. I can buy from Alibaba though "surprises from the Orient" are not well received...

That is unacceptably hot for decent longevity. Can you dig a hole to a cooler depth? What is the night time temps?

Bought 4 of the A123 24V pouch batteries from Big Battery. Three have been delivered (how lovely are split deliveries?). I'm a prepper of no intention of getting chipped so I can buy in the market place. These batteries will be stored several years - until the LA batteries in use decide...

Seems like the OverKill is about the only BMS folks are posting about. I still say we only need a cell balancer when used indoors for off grid solar. But a decent cell balancer curiously costs a similar amount to a BMS.

Agreed

I tend to doubt it is Energy Star. You will pay a heavy price for powering an old energy hog fridge I think. Inverter type fridges in America are generally the domain of the huge high end fridges for unknown reasons. Perhaps related to standard dark shingles while making white shingles a...

I don't recall the names. It has been several yeas now. A lot of people tire of the constant movement after a few years or so. Especially the ladies. I could see doing it part time - maybe 6 months/year.

Is this a dream? Breaking Milwaukee bits in copper bar? This should not happen. Copper is one of the easiest materials to drill. Lead being a little easier. Should be able to poke a hole in copper with morning wood. Ok - that was a bit extreme but the point stands.

Will dissected a Valence. While finding the batteries are beautifully made, the cells seemed rather ordinary and available pretty cheaply. I could seem them taking offence and changing the blend after that. Though I must say I had the impression that Valence used "li-ion tech", not lifepo4...

Store them cool if possible - certainly not over 75F if you can. I'd bet a dollar that colder is better. But never charge a frozen lithium battery (under 32F). Though I seem to recollect someone thinking that 25F is where the damage takes place - and don't count on that "seem to recollect"...

He never even told us where he is. I've seen so many one wonders stir things up and disappear forever it boggles the mind. I could also see a forum user creating the account to get folks excited about "unlimited Tesla cells" while snickering away. Of course anything is still possible.

$94? I flush my toilet with urine, use passive solar for 85% of my heat, that is kind of how thrifty I am. I have the environmental footprint of a rabbit, aside from the hikes with my dogs. I don't just use cheap plastic disposables, I reuse them. That is how I can afford to buy car insurance...

Everything I have seen and read indicates that cell balancing is reserved until the battery is fully charged. I never insinuated the CC or inverter would balance the cells. Hence the thread title: Making your own cell balancer?

This has got to be easy to do. Yet I have not found a good video on how to do it yet. No real need for active balancing. I'm almost certain that cells could easily be passively balanced 24/7. Why not let the BMS do it? Two reasons: 1) They wait until the cells are 100% fully charged. Presently...

My cousin has a masters from MIT in EE and is frequently unemployed due to being "overqualified". That's what I'm told. It is doubtful that youtube collapses any time soon. Seems to be growing in leaps and bounds. Think Yahoo will bounce back and body slam Google and youtube? I just don't...

Source was a pro solar guy on youtube. Didn't make total sense to me but he seemed legit and definitely experienced. Opinions seem to vary. Couldn't the junctions be replaced? At any rate flex panels had a poor longevity rep a few years ago. I just replaced a plastic headlamp two hours ago due...

Big issue I have is not always knowing when inverters can be hooked up to a circuit breaker panel. If they have 3 pronged 120V outlets the answer likely is - no. Of course there are work arounds for this but most of us seek plug and play I think. Most everyone talks about price! Same with...

Little competition in the manufacturing of such cells. Huge problem. How good would lithium batteries be if we only had a couple small manufacturers? I still consider it a tragedy of sorts. Make your own? How do you nickel plate the iron? I looked at it and could not rationalize the...

Getting an engineering degree is a terrible idea in my opinion. Will is ideal for what he does. Why re-invent the wheel?

Different users have different priorities. Imagine that. How are things at Ingsoc? LOL.

Something to consider: What deteriorates the output of rigid glass panels? Airborne particulates making micro abrasions over the years. With flexible panels you get some type of plastic instead of glass. How is that going to hold up to airborne micro abrasions. Or UV rays from the sun. How are...

Tesla uses great cells. Absolutely top tier performance wise. Each cell is fused so they are still pretty darned safe as lithium batteries go. You still need to know what you are doing. Unless you have a lot of spare time and morbid curiosity it may behoove you to trade cells for usable battery...

No I didn't watch that video. My statement still stands: Where did Will get his 40-80% quote from anyway? Could it be - a seasoned full time manufacturing battery expert with access to a lab? Perhaps someone like this? He got the quote somewhere - not from Battle Born. That was a - guess...
