 Hey guys, welcome back to my YouTube channel. This is Daniel Rosal here bringing you another video about the Canon XA40 professional camcorder. This is the delightful pro camcorder I picked up about. I think six weeks ago now, I've been using it pretty much every day since then and I really, really love this device. The only criticism or negative I would say about it, and that's becoming more clear, the more I shoot with it is that the low light performance is definitely a lot. It definitely suffers, put it like that. If you're in nighttime shooting conditions and you have some artificial lighting, it'll do a decent job, but if you don't have that, it really starts to get quite noisy images. So if you have enough money to be able to afford the XA50 with that one in sensor versus a one over 2.3 in the XA40, I would definitely say it's a worthwhile upgrade. So one of the first things I wanted to buy in terms of aftermarket stuff, besides this lovely shotgun microphone, was to get another battery pack. So the battery pack that this, I'm gonna just take it off here. The battery pack it comes with is the, it doesn't actually, ah, it does, it's BP-820. And from what I read online, the BP-828 is interchangeable now at 7.4 volts. I'm just gonna see if I can get this in focus. Might be a little bit tricky because I'm shooting this on a webcam. And it's a 1700 milliampere hour, I believe. I'm not a battery expert, but that's the capacity as far as I know, 1700 milliampere hour battery. So I couldn't find a OEM battery for sale in my locality in Israel. So I probably will get one in the summer because one thing you always run out of when you're shooting video for long periods of time is battery. But what I did is I went on to AliExpress and I found out, as I said, that the, it seemed to me as if the 828 or Canon actually recommend there's interchangeable product numbers for this battery, the 828 and the 820. So this is the B-B-T-828. And so this was listed as being like basically an AliExpress knockoff of this. Now, what my understanding for non-OEM batteries has been that they can't damage your camera. I may be wrong about that. Do not rely on this statement, check that out. I've heard that they will not damage your camera but that you might have some issues with the chip. In other words, the battery reporting it's level to the circuit board of the camera. So that is a big disadvantage. But it's, you know, it's for, there's give and take when you're buying non-OEM stuff. The second thing to say about this is it's a big, it's a big chunky battery. So this is a, this capacity is 2,900 milliamp per hour and it's also listed as 7.4 volts. So it looks to me that they have the copycats right just at least in terms of the voltage. I'm trying again to get this guy in focus and failing. But it's a 2,900 milliamp per hour lithium ion. Do not store in temperatures over 60 degrees Celsius. And let me just show you a size, a side-by-side comparison. This is the OEM battery from Canon on the right. It's the shorter one and the AliExpress battery. I'm just going to move out of the frame for a second. So it's a decent bit longer. But to me, that actually makes sense because unless you're using the OED viewfinder you have room at the back. So I'm going to just firstly slide in the OEM battery here. Just show you how an OEM battery is supposed to work. So I'm turning this guy on and it's reading out my power remaining as being 147 minutes. So it's pretty close to its charging capacity up there on the top right. So now I'm going to go ahead and swap in the AliExpress battery. Okay, so I'm putting the AliExpress battery into the camera now and it's definitely locked firmly in place. Now in terms of, here's the side profile because as I said, this guy's a bit chunkier than this. So it's taken up another centimeter. In terms of using the viewfinder, that was my main concern here. So you can still actually do it even with this longer battery. Now I can't remember, I did the mathematics before starting this video, 2900 over 1700. I think it came to 1.6. So you're getting actually 160% of the battery capacity of the OEM battery. So it should theoretically last a bit longer. Now of course the litmus test is going to be, is this going to report the battery level to the camera? So let's go ahead and find that out. I haven't tested this before shooting this video. So this is a live test. It's showing 100, no, it's just jumped right up there to 227 minutes from 140. So it does look as if it's reporting. And the next question is, can this guy be charged? So let's go ahead and try that. So I have the camera turned off now when I'm using the OEM charger from Canon. And I'm going to just go ahead now and connect it into the DC in-jack here. Now what should happen when it's charging is that the red light on the opposite side should illuminate. So I've just gone ahead and connected and the red lights popped on. So it looks to me as if this is working. I'm definitely going to do just a little bit more research before going out and using the non-OEM battery. I'm always going to just as a kind of best practice. I always use my OEM battery first because I do worry a little bit, but assuming that the worry is unfounded, that looks like it works perfectly well just to sort of refresh the essentials of this video. It's a 2900 milliampere hour battery. It's called the Canon 4Kan BP-A28. Now when these kind of knockoff companies are trying to come out with product numbers, they typically try to sort of replicate the actual. So it's BP-A28 and Canon's official one is BT or something like that, Batmax battery pack. It came in this box, I didn't really say a whole bunch, but how much you need to know about it, about a battery. Lithium ion, 100% more power. And it just says basically, dispose of used batteries properly. So I'm going to give this a shot, shooting and hope that it works out well.
