What are my options if I want to go beyond what the Victron Connect app shows about my SmartSolar MPPT controller? For example I want to check the heatsink temperature, possible deratings, etc. Is there some software like that from Victron or a third party? Or perhaps a simple app that can read...

My Morningstar TS-MPPT-60 gave up after some rough treatment from me. So decided to take it apart and have a look. Some pictures for those of you who have an interest in electronics. Above picture: Three large step-down inductor coils to the left. On the upper PCB is the main controller, a...

I can probably not fix my old charge controller, so I might be in the market for something new soon. Curious to hear what brands and models you are happy with. Something in the 60-100 A charge current range. Battery is 24V, panels are approx 110 V. I had a quick look at the Vicron SmartSolar...

My TS-MPPT-60 charger is ignoring my custom settings for absorption voltage for some reason. Perhaps someone has experienced the same thing and can give me some pointers. I've used custom settings for years, but now when I got new batteries, I changed the settings and somehow things don't work...

This video describes what happens on the atomic level when a litium-ion battery is charged and discharged, using terms that most people can understand.

I'm getting into canning and could use some advice. Will mostly be veggies such as potatoes, carrots, onions and tomatoes. But also beef, and stews. What pressure cooker do you use? Tasty recipes?

I expect to very rarely get below 80% SOC in my LiFePO4 battery bank in the summer months. Possibly half a year might pass before that happens. I know that LiFePO4 has almost no memory effect from staying in a narrow SOC range for long periods, so this shouldn't be a problem. But still I'm...

I assume that it is not for attaching an actual GPS (Global Positioning System) receiver, because what would be the point? So what is it used for?

I live in an off grid cabin deep in the woods of Värmland, which is in the western parts of Sweden, bordering on Norway. I came to this web site when I was doing research on LiFePO4 batteries, which I now have ordered to replace my lead acid battery bank. I used to work in the solar power...

Excellent presentation by Prof Jay Whitacre (holds several patents) on how a LiFePO4 works on a chemical level, charge/discharge profiles, voltages, temperatures, potential pitfalls.

Has any of you designed and built a Coulomb counter for LiFePO4 batteries, to keep track of SOC? My current lead acid setup already has a voltage and current sensor connected to an Arduino with a screen. Soon I'll switch to LFP, so why not take some time and implement a SOC monitor in software...

At manufacturing, are EVE cells tested at high current draw (1C or similar) to see if they can hold voltage? I mean for all grades (automotive, grade A and B). I recently had a discussion with a seller on Alibaba about this for grade B cells. I don't care about the cells (LF280K) having...

I have a 8 x 12V 100 Ah battery bank in 2s4p 24V configuration for my off-grid solar powered home. They are of type Sealed Maintenance-Free. Worked well for 8+ years, and I guess they are pretty much worn out. One of the pairs started getting hot while charging, so I turned off the system and...

Looks like one company trying different branding strategies. Products are the same, price almost the same, texts almost the same, offerings/bundlings very similar. https://www.litime.com https://ipowerqueen.com https://www.redodopower.com

I'm building a 24V 400 Ah LiFePo4 battery bank. My first choice would be to get 2 x 24V 200 Ah and do 2p. I've found a unit that looks good at LiTime. Then I saw that 4 x 12V 200 Ah in a 2s2p config is a lot cheaper. But is it worth the savings? Then I will have the potential risk of getting...
