ToolkitRC M7 200W Field Charger Review ⚡
So this one is the updated version of the m6 from last year with a basically an increase in uh power output from 150 watts to 200 watts and it’s got the updated interface that the m6d has so it’s got the nice uh two inch lcd color screen Here, um and we’ll, get into all that here in a second i’ll show you the charger here in a second i’m, going to show you which, what i’ll see in the box, of course, you get the charger you get a usb to usb cable. This is for firmware updates and then you get a quick start manual, so uh there’s a full manual that you can download and i’ll link that in the description. But you know if you just wanted to get a quick guide as to how it works. This quick start guide will get you going. Um i’ll, just show you the basic specs here. So the biggest change obviously is the charging power and it goes up to 200 watts now, instead of 150 watts but it’s the same size as the m6 it’s. Actually, quite tiny, just to give you an idea what the scale is like this is a 30 by 30 esc here on the left, and you can see what the charger looks like, obviously in terms of dimensions, it’s, it’s, very, very small, so just going over the Specs again here, you know it’s input 7 to 28 volts that’s pretty standard, but only up to a max of 12 amps.
So, if you’re, using with a external power supply instead of a dc input – and you want to limit it to 12 amps don’t, go more than that. This one also does have the measuring capabilities here that the m6 has in terms of measuring different signals. Like pwm signal ppm signal s, bus, etc also, can measure internal resistance. I’Ll show you that here in a second and then in addition to measuring um a servo input, you can also output server inputs as well to these various ones. Pwm ppm and s plus and they’re actually here on the side that there’s this little cover over here, that’s covering it up. I’Ll pull that off here and show you that here in a little bit later, so just taking a look at the charger itself, you get a two inch color lcd screen. I have a little exit button here, scroll wheel, that you can also press down on works. Pretty well that’s the same mechanism that the m6d uses. You have your input xt60 here on the left, 728 volts up to 12 amps, your servo pins are being behind this cover, and this is the usb ports. You can also charge uh via usb at 5, amps or 5 volts up to 2.1 amps and it’s also used for former updates with the included cable. This side. Here you have your xd60 output and the balance plug over here that’s going from 2 to 6s. It doesn’t go to 8s in this one, and then you have on the backyard fan output and you have these little legs.
You can prop up the charger on these if you want to have the screen at an angle. Okay, so just go ahead and plug it. In battery here’s, just a uh 4s lithium ion battery and it shows you the current voltage of that battery 16.44 volts current temperature of the charger so that’s why the fan isn’t on. I think that at a certain point, as you’re charging that should kick on and then you have your individual voltages for each cell so to get into the main charging menu, you just short press the scroll wheel, that’ll bring up this menu here, you can choose your Battery type there’s, lipo, high bolts, you’ve got lyfie lithium ion nickel hydride lead acid and uav. That say, does have a few different types here: uav bats uh. You have mavic 2 mavic s phantom and inspire going through the rest of the menu. Here you can change your different cells. You can choose a manual from one to six s or you just leave on auto, which is what i would recommend different modes here, of course charge discharge and storage charge. You can choose your end voltage here for regular lipo zoom goes from 4.25 down to 4.05 and we’re going to leave it on the default of 4.2, and then you can change your charge current here. I believe it goes from 0.1 amps to 10 amps. This is a 10 amp max charger and, of course, just hit start demonstrate here a battery here in a second.
If you long press the scroll wheel, it’ll bring up the charger setup menu here, you can change things like your input settings power type you want. Obviously, if you’re using a battery as a battery, but if you have a power adapter, you can change it to your adapter and then i’ll adjust these settings here then i’m going to leave it on battery. You can change your max power and max current voltage range here. I don’t think that’s let’s see if that’s just that is adjustable, so you can adjust uh up from seven volts and lower than 28 volts, but there’s that’s, the maximum range, of course, i’ll just leave it as that. That alone, security settings um, basically safe internal temperature, external temperatures. If, basically, if these uh settings are exceeded, it’ll shut the charger down for safety now like on the m6d. The battery selection menu here is turned off. If you turn that on, you can basically set up the like presets for certain batteries you use often, but if you i don’t want to use that you can just leave it off uh. You can change the backlight setting for the brightness of the screen and then this buzzer setting, which is actually turned on by default by turn it off, because it has a really annoying sound, but i’ll uh turn it on here. So you can listen to what it sounds like. So as you scroll through the menus, you’ll hear that buzzer and i turn that off, because it would make this video extremely annoying.
You have to change your theme from light to dark. If you like, the back black screens of the white background screen, and you can change everything back to default, if you want, if you long press the back button, brings up the other menu here, which you can measure. Internal resistance measure signal signal output and the last one here is power which will turn this into this output port here into your power supply. So you can adjust your power supply voltage from one volt, all the way up to 28 volts, so basically it’ll take whatever voltage you’re getting from your input source and basically adjust it to whatever you want to. So if you want to output, say 11 and a half volts at 2 amps, you can do that. So the amp is amperage goes from half an amp up to 10 amps max. So you can. So if you want to change these settings and then hit start, then what will come out of here in the output will be 11.5 volts at 3.2 amps based on your settings anyway, so i’ve got a little 3s battery here, i’m going to charge this up as Soon, as you plug it in you, get your voltages on each of the cells and let’s see. Does this show the internal resistance doesn’t show up here now i tested this before and if you actually go in and to the measurement menu here and then you hit measure resistance, it’ll go through this process of measuring the resistance of the cells.
Here at this current voltage and see here, it’s at 53 milliohms now, however, if you go into the charge menu, so i’m gon na go and charge this up uh. You know i got ta change the charge. Current 10 amps is way too high. So let’s say this is a 600 milli amp hour battery, so charge of 2c at 1.2. Amps hit start okay and as soon as it starts charging up and scroll over, you can see the different individual cell voltages and if you scroll over one more time, you can see the uh internal resistance measurements as it’s charging. This will change as the battery voltage goes up, but you can see here that when using this method, this number is vastly different from the other method, using the measurement tools so i’m, not exactly sure why that is maybe uh. Someone actually could rc could comment down below and let me know what the reasoning is in terms of the difference in the measurement and if you want to adjust the voltage in the middle of the charge, you just short press the button and you can adjust the Current here, so if i want to increase up to two amps, do that hit exit and then you see the amperage will go up. That’Ll increase the charge rate of the battery and then, if i want to stop it, i can just short press the scroll wheel. Go down to stop and that should stop the charge process all right, so they want to show you the uh screwable pins.
You have to put like a screwdriver or something into this little hole to pull this cover off, so they have this covered up pretty. Well. I guess most people probably don’t, use this process or these tools. So you have these two servo pins here and the input is on the left and the output is on the right and then you have the negative at the top positive in the center. And then your signal is on the bottom. So i’ve got a little servo here. I’Ll show you how the servo tester works and we’ll stick that on the output you can see. It’S, powered on and service server was pretty old and noisy and we’ll go into the serv measurement or testing tool section here and go to signal output and obviously want to output a pwm signal and also to auto. You can see how, as the value adjusts the servo changes, it’s a little slower and then i think auto one is the slowest, so basically it’s a way of testing things like that require a pwm input or ppm input, or s plus input. You can test those things using this charger, it’s kind of interesting to have – and this is probably something that i’ll keep and um probably keep this in the car i don’t know. I don’t really test these kind of things that often but it’s nice to have this tool available and it’s built into the charger which is kind of nice, yeah, so overall it’s a pretty nice little charger for the field as long as you’re not trying to charge Really large batteries at a higher rate, if you’re doing a lot of like sort of smaller batteries and you don’t mind charging bigger batteries at a slower rate.
You know 200 watts should be enough for most situations. If you need a charger out in the field to recharge your smaller batteries, it should be fine if you’re trying to charge giant batteries or really big batteries, um or, like 6s, like say, 5 000 milliamp hours at a high at a higher rate. This 200 watts is not going to be enough to charge this battery very quickly. You can do them. You can still charge them at a slower rate, of course, at 200 watts, it’s, just it’s going to take longer. So if you’re in a hurry, then you probably want to go with a bigger charger, but then you’re going to get probably have to get something a lot more bulky. We can kind of take up more space and also weigh a lot so for something like a field charger like this just carrying it around. This is great and i’m actually going to keep this in my car uh or my um, my fpv bag with the rest of my stuff, my gear just have it in there for anything. If i need a charger available to me out in the field, then this is going to work out great for that so i’m, going to use it for anyway it’s going to do it for this video.
