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...

I figured it out. It was a driver issue.

Just an update: I went with the Victron MPPT 100/20 "little beast" and a set of flex panel: "520w Kit" from Eco-Worthy. I took advantage of their 20% HOTDEALS promotion on ebay. A good deal I think. This should work...

It's just a phase...

My bad!

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...

Thank you. But, not possible to find a suitable single battery because of size constraints. They are all too long in length (13" or more).

I was thinking that too, but I can also park a wheelchair out there to charge, as well as the portable spare pack, so that doesn't have to be an issue. A pitbull attached to the chair might be a good idea though. That way, they'd just steal the dog.

So after looking around at extention cables I came up with an interesting compromise. Alibaba: a short mc4 to common SAE automotive connector, and then a couple of 15' 14awg cables with those connectors. So, for the $35+ I would have spent on a 25' solar extention, I have an adapter and a twoof...

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 love the "Insurance holder" name for the fuse holder in this diagram! "Isn't that just Precious!"

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.

Yep. That is what I am thinking. I can do a lot with idea, using flex panels. I think this disaster preparation scenario is probably the one situation that justifies for using flexible panels...

👍 👍👍Thank you! 👍👍👍

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...

Thanks Harry. From reading this I realize that I should charge the inverter before attaching to my DYI, BMI protected, wheelchair power supply. I just ordered a 25w 30ohm cement resistor to have on hand for it. I am still confused why it is called "Charging", as it seems like exactly the...

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...

I am building a solar battery charger for my wheelchair that I can hang in my patio. I am probably the first to try that!!

You are right. I happen to have a single burner propane camping stove that would work in stealth...

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 ... Sticking with a simple...
