The first of all, if you're new to the channel, I hope you'll hit the subscribe button so that you can get more great content about drones and other RC Hobby stuff. What I want to talk about today is how to store lipo batteries. Now this is a tattoo for cell that's, a 4 s 1300 milliamp hour battery, and this is used in a racing quad. It can also be used in cars, it can be used and anything that takes a 4s and uses this xt60 connector, which is what this get. This yellow guy is right here now, if you're going to store this for a long period of time, let's say you're not going to fly for a week or two or longer. What you want to do is using your smart charger. You want to go ahead and find the mode you can see right now, it's on lipo charge. What I want to do is move it to lipo storage and that was lipo balance fast charge and storage. So that's great. If you want to store your hobby grade lipo battery, but what, if you want to store a DJI battery? Well let's set this aside for a second. If you want to store a DJI battery, this is a battery for the Mavic air. This is a battery for the Mavic to works in both the Mavic 2 pro and the Mavic zoom right here and let's say you want to store it for a period of time.

You'Re not going to be flying for a while or let's say that you were on a trip, and you fully charged these. This has happened to me before you fully charge these with the intent to flying. Then the weather is bad and then you have to fly out the next day. Well, you don't want to fly with fully charged lipo batteries, that's just a bad idea. The energy in these things is explosive. It doesn't mean they're going to explode, but you're much better off, flying with batteries that are optimized for storage than you are flying for bat flying with batteries that are fully charged because they're going to be less volatile. So if you've drained them already and you're going to fly with them and you're going to reach when you get home a day later, then that's, probably not a big deal. I don't know give me comments if you think it is, but if you are planning to fly with them and then put them in storage after you've flown, you probably want to get them down to that optimal storage, which again is about 60, and that is where This product comes in, this is called The Phantom Angel. Now I've actually already used this, but I thought I would go ahead and open it, so you could see what is in it and kind of have that unboxing experience. So it comes with this glove, and the purpose of this glove is so that you can put this light bulb, which is a halogen light bulb onto it.

This is actually what dissipates the energy actually uses the energy by lighting this up. It comes with connectors that you ordered so right now. I have connectors for both the Mavic 2 and the Mavic air battery, so you can see they're slightly different, well, they're, quite a bit different actually, but they both have this xt60 connector on the other side. Now that has nothing to do with those other batteries it's just a standard format. The build on these things is great, it's all heat shrunk. The connector is very solid, feeling you're, not gon na pull it off accidentally. It just feels like it's, really solidly made by the way these are not made by a company. These are made by one guy named Alex, who sent this to me to check out, and I was just super impressed with how well built this thing is for your DJI batteries. So your light bulb and the reason they send you. The glove is because you don't want to touch this light bulb with your bare hands. The reason is halogen bulbs. While they dissipate a lot of energy, they also get really hot and they can actually explode. If you get the oil of your finger on them or they can puff up and be useless, so you want to make sure that, as you are handling, this bulb you're using the gloves so that you don't get your fingers oils on the glove. So what are the reasons you would want to use this? Well? First of all, there's a thing called deep cycling, which basically means that you're going to drain this thing all the way down and then bring it back up to the appropriate storage amount of capacity about 60, and that is really good for the cells versus either running.

It all the way down and leaving it down or leaving it overcharged for a long period of time. You really want to use this deep cycling as a way to take care of the batteries and make them last longer. Number two is that ability to do that? Quick discharge, if you are done with your flight and you're about to get on an airplane, and you need to carry this into the cabin you don't want full batteries, so DJI does have the ability, with these smart batteries, to actually dissipate them over time. You can set it up in the app to do it over a couple of days or up to I think 10 days. It'Ll dissipate them down to a storage level, which is great because that allows you to kind of forget about them. But if you want to drop them down to storage level right away or do a deep cycle on them, this is the device for you. So here is the Phantom Angel, also known as the Mavic angel. In this case, it is made, I believe, of aluminum it's. Very lightweight but metal, so it feels like it's really solidly made and it's got two switches back here on the back. It'S got one that says cycle and store. So cycle is going to be your deep cycle to take it all the way down and then back up store is going to be putting into storage mode, and in this case it has air and m2 or Mavic two labeled here on the back, so that you Can tell which one you're supposed to be in so now it's pretty simple to operate once you get it all out.

You go ahead and put the light bulb in and again being careful not to touch it with your fingers so I'm going to put this glove on there. We go and don't force it, but there is a way that it slips in there pretty easily and then what we're going to do is we're going to take our Mavic air. The original Mavic air battery, which right now is sitting at probably at about 60. For storage, which is a good place and I'm going to cycle it so I'm going to take the connector put it on the appropriate way plug this in here, switch it to cycle and to air one important thing: this won't work if the battery's turned off. So you want to make sure to actually activate the battery. Now the battery is activated, and now, when I turn it on, the light goes on and it's basically going to cycle this down to a very, very low amount of volts. This does not charge your battery by the way this only dissipates it so so you've still got to use your regular charger with it. But right now I am running this thing down through the cycle mode flipped with the flipped over to air and to cycle so I'm gon na take a look at what time it is right now, it's, 1140 and we'll see how long it takes for it to To run down to the cycle, so a couple more quick things that are here in the notes, it says never cover up the angel, which makes sense you don't, want to have anything touching it or on top of it, while it's doing this, because a it's bad For the bulb and B, this stuff gets hot and number two be careful.

What you touch you don't want to touch the heatsink while it's discharging, because that heatsink also gets very hot while it's discharging and then finally treat the bulb with care. As was noted before you don't want to get your oil of your hand or anything on that bulb, or it could cause it to swell up and break now. We started at 1140 it's 1143 and you can see now that the third light is no longer blinking. So it's actually drained some of the power out of it and we'll see how long it takes for this second light to start blinking and then to finally go out. Okay, it's been about 15 minutes and we're down to one dot on the Mavic err battery and that one dot is now blinking so curious to see what happens when it gets all the way down land land land time to land. I will say to if you get one of these don't stare at the light, I find myself looking at it and it is very bright and it kind of gives you spots in your eyes. If you look at it too much so resist the temptation to stare at it, and while this is finishing up, I do want to just say a couple of other quick things about this thing again: it's not made by a company it's made by one guy, who Seems to have put a lot of time, effort and love into this thing, because it's it's not only functional but it's, very well made it's very cool.

Looking it. He has a little graphic of the wing for the Phantom angel or Mavic angel on the box. Also there's a graphic of it on the device itself. The device is very clean, very professionally put together and just looks like something up. There goes the light it just went out. So our time was 21 minutes and, as I said, this battery was set at 60. Ish it was like 2 full lights and a blinking light when I put it on here, so I had stored it at the right amount. But if you're looking to discharge it faster and do a deep cycle on it like I just did for battery maintenance. That'S great 20 minutes on here and it's down to basically zero at this point so now I'm gon na plug it back in and charge it back up to a full charge and then after I do that I'm going to actually put it back on here and Cycle it down to storage so that it's in the optimal setting and it's been to that entire cycle. Now I do think this deep cycling allows your batteries to have a longer shelf life and to maintain their usefulness for a longer period of time, because what you're doing is you're kind of telling the battery. This is what full looks like this is what empty looks like and you're gon na play in this range in between okay. So what I have here is a Mavic two battery that has been on the charger.

It is a hundred percent charged. So what I'm going to do now is take this cable off and put on the Mavic two cable right here using the xt60 connector, and you never want to pull these cables by the cable. If you can avoid it, you really want to grab the connector. If you can and then I'm going to plug this end into here and I'm, going to switch it to storage and M 2, which is the Mavic 2 looks like it's all connected, so what this should do is it should knock it down from this full charge. To a storage charge which should be about 60, so it should give us two solid lights and then one blinking light when it stops so I'll go ahead and, Oh first, you have to turn on the battery. You don't forget to do that. So the batteries on go ahead and turn that on and the time is 1218, so I'm gon na go ahead and let this go until it stops okay, so the light just went out seconds ago and now this is sitting at two solids and one blinking. So I'd say 60, so that's right where it needs to be for storage, and it took about 15 minutes. It went from 1218 to 12, 33, so I'm doing my wrath, math right, that's, 15 minutes pretty good, took it down from a full charge to 60 and ready to be stored in 15 minutes.

So I guess when it's done, one other thing you want to make sure to do is just turn that battery off, so that it's not running anymore, so I'll set that over here and I just want to say nice job Alex. This thing is very, very cool. Very well made it really seems to do the job as far as dissipating the battery to either a deep cycle charge or a storage charge. I like the fact that it's got multiple options for both cycling storage and two different types of batteries: I'm, not sure of all the drones and batteries that this thing supports. Aside from the Phantom, the Mavic error and the Mavic 2 but I'm gon na guess that probably does some others. If you request it I'm Beth Alex can make it for you, so I'll put all the information below for Phantom Angel and how you can connect with Alex to order one or ask questions of him. There'S, a lot of information on this website I'm not getting paid to do this at all, but I will say in all honesty, I do like the build of this. I do like what it does and I'm looking forward to having it so that I can take better care of my DJI batteries.
