Does anyone on here have this 48V 100 ah Weize server rack battery? Compared to other server rack batteries, the price seems too good to be true. That and free shipping, apparently from a US warehouse? What's the catch...

Wow, that's crazy prices, but risky........................

Does anyone know why Victron charge controllers price just went WAY down? I recently purchased a 100/50 for over $300 and now I see it is on Amazon for $184!! Will these prices last? New pricing strategy? New models coming out?

My current mini split project, lots of lessons learned so far LOL.

Will solar panels get fried if there is an EMP attack? Google gives differing answers.

Are the pouch cells any good?

Excellent questions, I have no idea, maybe someone with more knowledge will chime in. I would test it but I have kids and thus no time.

I got it from my shunt battery capacity monitor, I don't remember the voltage this morning the pic below was taken at another time.

Thanks Bill, I will check everything but the only variable between the 34 watts and the 375 watts was me turning off and then on the LV2424 so that is my prime suspect right now. Also, I have three smaller panels on a different charge controller that is measured by same shunt meter as the...

Yesterday I ran my batteries down to around 25% of capacity in my RV using some power tools. This morning after the sun was well up I went out to check on the battery state of charge and charging watts. In full sun it was only getting 34 watts of solar from 1000 watts of panels. I thought it...

I had 2 different MPP Solar units fail, one was throwing an error code upon installation and the other one started putting out 220 volts instead of 110 volts, 9 months after purchase. I bought from Ian in Utah (https://usamppsolar.com) and each time he immediately sent out a new unit before I...

Thanks Capt Bill, interesting results. I will do some testing and see what happens with my setup. I just ordered 8 new 272AH cells so my current strategy of 27.8 bulk and 27.8 float as recommended by Lion Energy might not be the best for my new cells.

Yesterday I changed my settings to 27.8 bulk and 27.8 float as recommended by Lion-energy. It worked! It charged right up at full charging watts and stopped charging when full. I will keep testing and report back if anything changes, but right now I consider it solved.

I contacted Lion-energy and asked what settings I should put for my bulk and float, and they said set both to 27.8. I will try that next, but am not optimistic.

So I am still trying to find the best settings on the LV2424 to fully charge my batteries. As previously discussed, at around 40% state of charge (SOC) my LV2424 would significantly reduce the charging watts and the sun would start going down before the batteries were full. The smoke from the...

Thanks for that, I see now I was confusing "float" and "absorption" in my post. I think I need to study up more..............

OK, so this morning before sunrise I turned off the solar panels on my RV and ran some loads so at 1310 hrs the batteries were at 38% (26.4v). I then turned on the panels and the LV2424 fired up and started charging the batteries at 430 watts so I went back in the house for my covid-telework...

I was testing mine yesterday after reading this thread and sure enough at about 40% of battery charge the charging amps go way way down. I have a separate charge controller for 3 smaller panels I have, so at least that one fully charges the batteries (but it takes a long time). If I can't...

So every time you want to buy something on the internet you set up an online store and buy it from yourself? Interesting strategy, but what if you have a complaint with the service or the product? What if it turned to blows between the buyer and seller? It would be like this:

Thanks Raven, you were right!

Great idea, I will check it!

Upon closer inspection I see an issue with the middle wire. How does the middle wire conduct negative return power? I don't see any metal connection???? How does this work? How does that work???

Look what mail-lady (mail-person?) Alejandra brought me today. It has 3 10AWG wires soldered in already. Google tells me that is equivalent to a 5AWG wire, so about 150 Amps.

Thanks for that link, good stuff although my head hurts after reading it :). From the link: So I read this as when using the LV2424 inverter, the AC neutral (white wire) should be connected (bonded) to the DC ground (vehicle chassis) but when plugged into shore power, it should not. Am I on...

Got my LV2424 all hooked up and running in my RV. I have the AC output running through a GFI breaker. When I plug in my AC tester it is showing open ground, is that normal? Is there anyway to ground the LV2424 in an RV?

Nobody knows how this will play out, but it does not look good right now. 35 million people are locked down in quarantine. Why would China lock down 35 million people if only 100 people died? Did you see the videos of people collapsing on the streets? China is all about making money, but...

Has anyone used this?: https://www.amazon.com/gp/product/B07TN3RLYZ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I have no information, but if there is one in the works he needs to work on his marketing skills because he keeps recommending other brands and suppliers of batteries :)

I found out that you can cut off the batteries from the app. If you see this screen then there is currently no electron flow: This screen means electrons can flow: The default is no flow (had to figure that out the hard way).

It also has "Battery State" view, "App Setting" and "About Xiaoxiang" views.

Ok, so I got it up and running and the bluetooth app connected without any issues. When I tried to change the low temperature cut off in the app it wouldn't take when I hit submit and went back and checked it. I played with it for a while and figured out you have to hit submit 3 times for it...

In this diagram it shows a relay hooked up, but it appears it is always on. It that safe and prudent? Is there any fire danger there? Maybe I should add a switch and only turn on the relay when I want to use inverter power? Here is the relay I have on order:

Got my batteryhookup BMS in the mail yesterday, no instructions, no wiring diagram and no video. Oh well, it should be straightforward. Like Will said, it only has 2 10 awg wires for the pos, and 2 for the neg so what is that like 60 amps max at 12V? (the online charts for amps for AWG are all...

I found out when I was testing my setup that it does the same thing. When it shuts off the power, I have to manually unhook all leads, count to 10 then reconnect the leads to get it going again. I guess it is more of a catastrophic doomsday shut off device than it is a hands-off voltage...
