Okay, so what's up guys? What's up guys? I don't know how to start it. We got new toys. How about that? What's up guys? Back with another video. This time we're going to use them a little bit different. I got some new toys to review and kind of go over. The Opus BTC 3100 Intelligent Charger. I got this on GearBest.com and I'll go ahead and include a link down below for everyone who would also like to take one of these up and test some batteries of their own. It's a charger and battery analyzer all in one. As you guys saw before I have a ridiculous amount of 1860s that I'm working my way through. It has grown exponentially even. These are all tested. These are all tested. These are all tested and I've even got overflowing here. Labels stopped mattering because I got so many of them. And with this charger I don't need all of them now. Not to mention, don't have a hard attack because I know this is not exactly the safest way to start these. There's all of these in here. And that in itself is a drop in the bucket. I've gone through, I don't remember how many batteries I've gone through, but I know I have 95 more laptop batteries waiting to be torn apart. Which is what? One of the upcoming videos is going to be on is how I get them out of there. So yeah, let's get to talking about this. To start it off, I'm going to do something I haven't seen anybody do, but I wish everyone would do. I'm going to give you a full view of the entire directions. So if you are for any reason looking for instructions, you can't find yours. You simply want to know the full function of it because I'm not going to go super in depth. I'm going to give you a general idea of how it all works. This would be the instructions right here. And there. So man, she loves these videos every single time she loves to join in. So go ahead if you need the direction there. I think if you want to know more in depth about this, go ahead and pause it on that part right there. Next, let's talk about the charger itself. If you look right here on the back, it says it will do nickel cadmium, nickel metal and lithium ion. And the lithium ion size, it'll do 10, 340s, 10, 440s, 1450s, 16, 340s, 18, 500s, 18, 650s, 26, 650s, and 26, 500s. So yeah, it will do a variety of batteries for you. All right, guys. So here is the charger itself. As you can see, when it is plugged in, they all show no when there's nothing in there. Go ahead and flip on the display here so you can see what's going on. First, we have the mode button right here. This will let you go through the different modes. The current one is on charge and test. What that will do is actually fully discharge the battery and then charge it and keep track of the capacity that it puts into the battery. So you know the battery is full capacity, which is specifically what I'm looking for. It will make categorizing of these batteries so much better. Whereas right now I have to charge them to possibly four at a time and then discharge them one at a time in my current tester. This will do all of that in one shot and that's exactly why I got it. We have a quick test. And what quick test does actually is test the internal resistance of the battery and then applies a load to it for 10 seconds and kind of estimates the battery's capacity from there and also gives you a reading of the internal resistance. It's not super accurate. I'm not exactly. I guess it's more of a good battery, bad battery situation. I saw I really won't be using that one too much. The next one we have here is charge. Pretty straightforward on that one. It simply charges the battery to 4.2 volts. You can select the current either 200 500 700 or a thousand milliamps to put into it. So the next setting we have on here is discharge. Discharge mode will drop nickel cadmium and nickel metal hydride batteries down to .9 volts and lithium ion batteries down to 2.8 volts. The debate on what the safe discharge ranges a lot of people will not go past three volts on their lithium ions. I for testing purposes, I like to go to 2.7 just to get a full range, the absolute maximum capacity of a battery. When in use, I'd probably go 2.8 to 3 volts somewhere in there. So next one you see here is discharge refresh. In the discharge refresh setting, what it does is it will charge and discharge fully three times. And it says this can take tens of hours up to days to complete depending on your current settings on it. It also uses the charge rate as the discharge rate or the load. I guess it wants to put on it. You can use that to refresh if you've got some batteries that just you haven't used for a while. This will do its best to refresh them to get some of the capacity back. But I, again, I don't know how much it's going to help, but it's better than nothing is the point. Let's go ahead and pop some batteries in here and see how it goes. I have chosen 4.1860s which I am expecting quite a bit out of actually at least out of three of the four of them. These three right here, they have this kind of translucent red wrap on them. I've tested a couple other ones of these that came out actually over 2,700 milliamps, which means they were probably somewhere 31 or 3,300 milliamps to begin with. This other one, I'm not quite sure I just grab it out there as well. You can see it's not translucent and it's got a different color top on it. Let's go ahead and pop them in there and see how it works. Let's see what happens here. Let's go ahead and select all four of these since we are going to test them all together. Let's go ahead and get on the setting we want. I would like to do charge and test. There we go. Let's go ahead and select the current setting we want. It has 0.2 amps, 0.3 amps, 0.5 amps, 0.7 amps, and 1 full amp of charge. Again, this is the charge and discharge rate that you are setting with this so it will parody them to each other. Let's go ahead and let it charge at one amp and see how it goes. While we are doing that, we go ahead and hit the display button and flip through some of the settings. We have voltage, we have milliamps, which obviously is none yet. Time, which hasn't been a minute yet. We have the current rating that is going into them right now. I just realized another feature that I left out on this after I actually put on the charger. I noticed that the fan kicked on. It does have a cooling fan. I mean, you have to imagine there's at least four amps of power going through this right now. He is definitely going to be an issue without a fan. It does have a cooling fan. It is relatively quiet. I don't know if you can hear that. Let's go ahead and let these charge and we will come back afterwards. All right, guys. So three of these four batteries are done. This first slot is still not done. The second one, as you can see here, is 2735. The third one is 2716 and the fourth one is 2749. The fact that I was able to read those out in my display here backwards is impressive. Go dyslexia. Once they're done charging, you can go through and see this is the actual amount of time it took for each one to test. That last slot looks like there may be some issue with that battery. I'm not quite sure. I may retest that one. Next, you have the current amount of current that is currently going into each battery. As you can see, these three are in trickle charts. This one shows to still be charging. I'm guessing there's a really high internal resistance on it. And it just can't seem to get to its full voltage as you can see here, which is the next screen. Battery 2 is at 4.2. Battery 3 is at 4.19 and battery 4 is at 4.2. Battery 1 is showing 4.14. It was just at 4.15. There definitely seems to be some sort of issue with that one. I have to play around with it a little bit more to know exactly what's going on with it. This has been a quick review and overview of the Opus BTC 3100. I love it so far. It's made my life so much easier with charging and analyzing each one of these batteries so I can categorize them. I was only able to do 2-3 a day before because how long it takes to charge them and discharge them. I can do 12 of these, maybe 16 of these a day in one step. Well, I guess that would be 16 would be 4 steps, but I don't have to put them on a charger and then put them on the test area. It's just done and I let it go. I'm getting through these batteries a lot quicker and I'm about to where we're going to start building the first cells, the first pack. We can do some testing. I may or may not test it on an electric scooter that I have. That was donated to me for this project. We might do that. We might just go straight to a 12 volt pack and hook it up to a hydraulic pump. See how it goes. Let me know what you guys think in the comments down below. I let you guys know where I got this from but it was not a paid review. I didn't contact them in any way. I simply found this and ordered it. I do have some things coming to do reviews up so that will be coming. I will be back shortly with some reviews and some other fun projects that got for us that are on the way now. We're going to break into some Arduino. I have no experience with them so we're going to go ahead and start doing that and see how that goes. Be sure to subscribe so you can see what all of the 600 plus 18650s that I've got around are going to be going to. Don't forget to click that like button down below. Most importantly, and I mean this is do not forget to leave comments down below. The biggest reason I do this is for the discussion because I absolutely love talking geek with other geeks. So I will see you guys next time and I will do my best to get more regular with these videos. So yeah, I'll see you guys soon.
