Hello again, First a little about my batteries. They are from the ring doorbell system. They consist of LG D2's (blues) and Panasonic A's (Greens). Here are some pics. I am getting about 60% blues and 40% greens. Lets talk about the IR of both (thanks Wolf). The blues are...

Hello again, I'm still in the process of testing 18650's, so I am just trying to think ahead. Not posting my build thread till I'm closer to building the whole project, not just battery packs. Here is a basic diagram of what I am thinking. Inverter/charger: I am leaning toward a LV5048...

Hello again, We bought a bunch of chickens about 2 weeks ago, 70 Cornish crosses (meat chickens) and 14 egg layers. Call me a prepper, or a doomsdayer, but meat prices were getting high and I guess we're bored. The meat chickens are suppose to get to 6 pounds in 6 weeks. They are...

Hello again, Has anyone seen this...

Hello again, https://www.ebay.com/itm/Lot-of-20-Used-270W-72-Cell-Polycrystalline-Solar-Panels-270-Watts-No-Vinyl/264728740518 Would you buy these panels? What does the no vinyl layer mean? Does it matter? Thanks in advance, Zerb

Hello again, I finally got my IR tester from China (took forever just to save a few bucks). It is the SM8124A. Is this an accurate IR tester? Picture: Thanks in advance, Zerb

Hello again, I noticed something weird today when charging some batteries. I always unplug the main leads when loading batteries in my holders (holds 24 18540's). When I plugged in the main leads before I could turn on the charging program I noticed the temp of the unit starting rising and fans...

Hello again, I bought a Kweld spot welder and it came in last week, (I don't want to solder to my batteries). I bought some SPIM08HP's to power it. I built it in a 7s config and the Kweld would not calibrate. The error message was "overcurr". The battery pack was too much for the Kweld. I...

Hello all, It seems that all I do with my free time is open/precharge/charge/test batteries. I've gotten blisters from opening battery packs. I even dream about batteries. This is getting out of hand. At least I've made a dent. I am about half way 700/1400 needed to start building my battery...

It's me again Margart. lol Another post, another problem. Why it is always that way. If there is a problem, it will happen to me. I bought the Kweld spot welder and need a battery strong enough to power it. I saw online that some are using the SPIM08HP's to power it. I built a 7s battery with...

Hello again, I bought 10 LiitoKala Lii-500's. I can now test 40 18650's at once. No making fun of my rat's nest of wiring, lol. It is powered by a server psu, top right hand corner. So, my thought process was to take the same 40 batteries and round-robin them through each LiitoKala. I...

I tried, I really tried. Maybe it's my lack of soldering skills or just bad luck, but I just can't get these to work properly. Either they just don't work, or they under charge, or they over charge the batteries. Thanks for all those that helped me try to get this project to work. I now have...

I got my iCharger 4010 duo in today. I am wondering if anyone has tried to do this for a power supply: I have a few extras from mining cryptocurrencies and am thinking about trying it. Just got to wait till Saturday for the nylon screws and washers. Thanks in advance, Zerb

Hello all, Others might know this, but I wanted to share a good resource for awesome batteries. It is from the Ring doorbell system, or whatever it's called. You know the doorbell with a camera. Here are some pics: The last 2 pictures are the same type of battery. I...

Hello again, I have been processing and testing cells it seems like forever now (only 1.5 months, lol). I finally got some balance leads for my Imax b6 and tried to hook them up. Here is the first thread about my process: https://secondlifestorage.com/showthread.php?tid=9009&pid=61572#pid61572...

Hello all, I need a little help and it's time to ask the guru's. I am still in the early stages of collecting and processing 18650's. It is taking forever to charge and test all these batteries( I am about 1/2 way of my 1350 18650's). I did a bunch of research and built some charging boards. I...

Hello all, Hope everyone is staying safe during this covid19 crisis. The reason I used the subject "Experienced Noob" is, I know a little about electricity but not a lot about powerwalls or solar. I have done lots a research and am a fast learner. I am about to start my project and wanted to...
