Plants can generate electricity
Researchers have discovered that living plants are literally 'green' power source:
they can generate, by a single leaf, more than 150 Volts, enough to simultaneously power 100 LED light bulbs.
Researchers also showed that an 'hybrid tree' made of natural and...
In the process of cutting my own heavy copper busbars customized for a 8S 24v 100ah build I came up with a template for drilling and cutting them from flat bar copper.
The real moment of truth is when you are about to install the bus bars in series after the parallel top balancing. This is when...
Well, now that I’ve received it, I’ve attached a two amp Anderson connector to both it and the power pack of my wheelchair, just for giggles! I plugged it in to my angle grinder and gave it a whirl. Now I’m wondering when I’m ever going to need an angle grinder during a blackout. But atleast...
I am building a 8S 12v/100AH pack for a power wheelchair. I will use a DALY LiFePo4 8S 24V 100A BMS (common port - whatever that means) with it, connected with some kind of fuse protection, preferably a breaker switch. I have been following "DIY Solar Power with Will Prowse" YouTube videos...
I just made a couple of sets of copper busbars from solid flat mill Bus Bar Stock that I found on ebay for about $12 each per 14" long bar. That is long enough to carve out about 8 bus bars. Aluminum bar stock works too, but it only it has 61% conductivity compared to copper.
(The bar stock I...
That I understand. But that doesn't address my question. Can battery cells set up in parallel, sitting idle without anything connecting to the main terminals (e.g. "Rail") balance into a common SoC. If so, by what process. I don't think so. I think some others do though. Please explain.
No dilemma.
Will talks of being homeless living out of van.
Me, I was homeless too once, living in the cabin of my 26' fixerup sailboat throughout one Virginia Beach winter. My point being, We have sure come a long way from that.
I have discovered the joy of Poverty, having lost everything...
Good Stuff!
...and I agree with you about the miscalculation of estimated running amps. According to the Owner's manual the original batteries are a pair of Group 27 12v 105A Gel batteries. Being SLA their voltage range is a wide swing from about 11.5 to about 14.v I think. Twice would be in...
I am not talking about a BMS and how it passively balances. I am talking about the case of two cells, one fully charged (Cell A) , the other in a discharged state (Cell B). Assume both battery cells are healthy. Check voltages with an accurate VOM, like a Fluke meter. Then set them up in...
It's nice to have the right tools! I was able to make do with what I had. If I could have taken it somewhere to have it done inexpensively I would have. These days that probably will never happen though. So, a hand drill, hand jigsaw, a strong table, big clamp, a piece of scrap 2x4 and some...
But isn't that charge voltage limit already a programmable parameter of the (Overkill) BMS anyway?
I hadn't heard of Arduino before. I Googled it:
People also ask:
What is the Arduino used for?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino...
Thank you. I hear you and appreciate your point about selective listening. A lot of that goes on in Congress lately. Nobody gets anywhere like that.
I keep it topped up and have never run at low SOC. Never below 40% while out and about, keeping an eye on my ammeter constantly.
It would be best to let the BMS handle all connections in/out of the battery pack, safety wise. I like the concept though as perhaps a solution to a problem I haven't encountered yet. Thanks!
Thank you. I appreciate your effort to explain it to me.
However, everyone seems to be missing the point. I am being treated like a small child asking how immaculate conception works. You can carefully and politely explain how human reproduction works until you are blue in the face but I will...
I am sort of taking it on faith that it is specifically a 8S 29.2v wheelchair charger. It sounds perfect...
I hope it is, anyway. If the ammeter is accurate enough I should be able to unplug it at whatever point I like to charge it to 80% or whatnot. We will see. As a layman I don't know if...
Wow! Now we are getting somewhere!
Paired with a single good used full size 100ah 12v panel, this might fit the bill.
I probably wouldn't mount the charge controller on the wheelchair though. I would be more inclines to store the panel inside, then deploy it, attaching the controller to...
That is so cool!
Sounds like I did good! It sounds sort of like a high frequency inverter works, no?
I have some studying to do on all of this now, to try to better understand all of this and cut through some cobwebs....
Watts/Volts = Amps...
Amps x Volts =Watts ...

Or don't look down the barrel of your .loaded .45 side arm when it jams...
I once caught myself doing just that with my Colt 1911, carried away in my confusion at the pistol range. Thank god for the grip safety. I was staring down the barrel, pulling hard on the trigger, trying to clear the...
Seems a bit extreme - just to make rechargeable batteries for my electric wheelchair...
Anyway, this thread seems to have gone all the way to Cuba and back.
End of Hijack.
:cool:
Thanks guys.
I have watched countless videos of balancing the way you do, and also read about doing it cell by cell which is more trouble to do. I figure I will test each cell with my Fluke VOM and individually charge the cells to 80% with the HP power supply, then parallel balance like you, let it sit...
I am not affiliated with the author.
I am new. Maybe this is old news.
I just stumbled across this on YouTube which should probably be of interest to many of us here. This is a wonderfully instructional video about a serious off grid DYI Solar Power installation on a farm.
I learned stuff...
So what is the minimum Victron SmartSolar model that I can use?
75/15, 100/15, or 100/30?
Well, I decided to go with this one. I probably can't go wrong it... Right?
Or, for less value @ Amazon, but why would I ?:
Hmmm... So are these "bifacial" panels ?
And if so, what if you were to slide a glass wall mirror under them, or at them? Can mirrors be used with solar panels with any effect?
