This file talks about the basic terms and is designed for beginners. It also talks about boost and buck convertors, boost/buck convertors, and battery types. There should be a button in the upper right of the page to print this if you want. The Print button makes it nicely formatted for your...

It would be nice to have a summary of all the pros and cons of each generator so we can quickly read through it. It takes quite a lot of time to listen to all the videos he's done on these things. :)

I didn't know they had reusable zip ties but I found some on Aliexpress so I ordered some. They have an extended tap on the release mechanism to make it easy to release and reuse the tie. They come in many colors. Here's an Aliexpress search.

No joke. March 2019. A bill to let Iowa utilities charge a new fee to customers who install solar panels is among the policy proposals that have cleared a procedural deadline in the legislature. Senator Michael Breitbach, a Republican from Strawberry Point, said it’s fair for all customers to...

This energy map can give you an idea of how much energy you can expect in your location. Naturally, you must account for seasonal variations too. https://www.energy.gov/maps/solar-energy-potential #solar #solarmap #map #energy

I have the Harbor Freight Thunderbolt panels with charge controller and a 12v lead acid battery. I got this device to measure the amps, volts and amp hours coming in to the charge controller but I am still unsure how to wire it to my system, even after doing some Google searches for diagrams...

I'm testing some AA lithium batteries that are charged via a built-in micro-usb port. On power banks I normally test via a discharge test. I do not yet have the equipment to test these AA cells via a discharge test. Most USB testers only go down to 3.7vdc. But when testing a lithium power bank...

I didn't know where to put this, but LEDs can generate power, like a solar cell. A red LED can generate 1vdc. Example video from Steve Mould. Fun stuff.

I'm looking for a DC ammeter with a ring to detect current coming from my solar panels going to the charge controller. I already blew one meter as I think I wired it the wrong way. So I'm looking for this simpler option with the ring that one wire goes through. It should have 2 decimal places...

Like for storm survival, power outage hints (which would include more tips besides solar power)? Or would that fall under the "Off Grid Living Advice" forum we have?

This is a 4 panel 100 watt system, each panel is 25w. I think I paid about $150 for the system in 2017. It comes with a charge controller. The charge controller has 2 inputs (+ and -) for the solar panels, 2 connections for output, and 2 connections for the 12vdc battery. It comes with a...

He has good videos on this subject, tests new batteries, new BMS systems, invertors, etc. I think he converted his VW wagon into an electric vehicle. He might make for an interesting watch. https://www.youtube.com/user/jehugarcia

I have a selenite tower, it's a large crystal with a 1.2" hole down the center and the walls are translucent, solid material at least 3/4" thick. I want to put a small LED puck inside that changes colors and control it with an IR remote control. Since I cannot find a system that uses an LED puck...

Below, the anode is negative. But in this chart below the anode is positive. Can someone help me understand? I'd like to experiment making DIY batteries at home from different materials. I know I can't make them cheaper than batteries from the store, I just like to experiment. Thanks!

I did a search on Youtube for [aa battery reviews]. Different reviewers test how much capacity they have, cheapest price per amp hour, and consistency. Summary: Dollar Tree Sunbeam AA batteries were most expensive per amp hour. Higher grade batteries were usually cheaper per amp hour but not...

I don't want to use these for smoking I want something small for atomizing essential oils for the room. Anyone know what happened to these on Aliexpress? Search results give lots of results but when I try to go to 6 different product pages I get "page not found" every time. Same issue on...

I want to put solar panels outside my home. The front of my home gets good southern exposure (for Michigan). But all other equipment I want to keep inside the house, like batteries and charge controller. My house is likely cement block in the front. What's the thing called that would be a...

They seem to have similar nominal voltages. Lithium: 3.7vdc, LiFePO4: 3.2vdc. What's the max voltage to charge a LiFePO4? How about the cutoff voltage for LiFePO4 upon discharge? Typically charger boards for lithium batteries charge to 4.2vdc and Chinese controllers often discharge to 2.5vdc.

I thought we could have a preferred vendors thread and get it stickied. @Will Prowse Please post your preferred vendor here with a link to their website or product, even if it's on Amazon, Ebay, Aliexpress, etc. It would be handy to have people with actual experiences with vendors which are...

Including 18650 and larger. https://hypercellbattery.com/lifepo4-battery/ I was just wondering if they came in AA or 18650 formats. I don't see AA yet but this is interesting. But the 18650 capacity is only 1400mah, while other Lithium 18650s go up to 2500mah or so.

Hi Will, I just found your channel this week as I'm very sick with some really nasty virus burning through my sinus. I like your videos. I do have a small PV system and it works fine, it's the Harbor Freight 100w system. The panels don't create much power so I might upgrade the panels...

I'm trying to test the capacity of some AA lithium batteries that are charged from a micro-usb port. I have tested their capacity while charging, now I want to test their capacity from discharging and compare the results. I'm having a very hard time finding testers that willi go down to 1vdc or...

I'm referring to things like solar garden lights that are kept outside where winters get to -10F on a regular basis, and summers up to 80sF regularly. Naturally, some winters get down to -30F ambient and some summers get to 112F ambient. Seems like these ups and downs would shorten the life of...
