[@abodemoose6181]

I'm not sure if you know this but this is the only video on KZbin (probably on the internet too) that shows what you're plugging into the input port. I'm new to the hobby and I've been searching for days (literally) for a tutorial on how to storage charge! Every video I've watched shows a close up of the screen of the device they're using without actually explaining to the viewers what to plug and where to plug. You explained the whole cycle. Thank you very much!!

[@RCVideoReviews]

You're welcome. Glad you got the help you needed.

[@vincentngo9494]

First and foremost, phenomenal video with great attention to detail. I have 3 questions. 1. How efficient is the “recharging function”? 2. How does continuous mode work? 3. What is the point of pairing this with the ToolKitRC P200 Power Supply?

[@RCVideoReviews]

1. Not sure. I haven't tested. 2. Continuous mode will start charging the next battery with the same profile as the previous battery with nothing but a battery change. 3. The M7 is a DC charger. You either power it with a battery or some other DC source like the P200.

[@DavidG2P]

Thanks for the review! Is it true that the is limited to 10S = 20V @PB ?

[@simtcr]

I am running 2.0.1, power supply output option is missing, any thoughts?

[@popitn2nd]

Why IR does not show during charge. Did it give you a result after the battery was charged?

[@simtcr]

Can I use this to charge 2x 2500mah Duracell nimh batteries? What charging current and nixx peak I need to set?

[@ivanluhi]

Great review! Would you rather have this one or the ISDT Q6 Nano, (let's say they are the same price..)?

[@simtcr]

I have this, but not able to charge 1s lipos. 2s and above worked fine. When I try connect 1s and charge I get error balancer port cell error. I tried set cell count to auto as well 1s. Nothing helped. V2.00. Any thoughts?

[@RCVideoReviews]

It’s not a 1s charger. The product description specifically states 2-6s. “ToolKitRC M7 200W 10A 2-6S DC Smart Charger & Diagnostic Tool”

[@simtcr]

@@RCVideoReviews I took v2.01 update and now I can charge 1s lipo as normal.

[@tf1389]

Yes, please make a video on the calibration process too

[@RCVideoReviews]

Got it. Thanks for the note.

[@hspeed3656]

John I didn't see a balance port for when you are pushing the power back to the input battery. is this not a concern? I am sure it wouldn't be used very often but I think it should be there. Now I am new to Elec. planes, came from glow so no expert here or even close. But very cool charger.

[@RCVideoReviews]

There is no balance port on the input side. For regen discharging you really don’t want to be pushing the source to anywhere near its peak as there is no monitoring on that side.

[@The-bashing-zone]

I think the better way would be to plug batteries you want to discharge to the input and set cut off voltage to the desire sweet spot 3.8V * number of cells. Two bird with one stone. Discharging packs to storage and not possibly overcharging the "source" battery.

[@FL_Engineer]

Question on the recycle function... What's the advantage of doing it this way vs. just swapping the input/output?

[@RCVideoReviews]

The regen discharge focuses on the state of the battery on the output side. i.e. It changes it's state from current to discharged or storage based on parameters in the profile. i.e. If I set profile to storage @ 3.8v/c, the regen discharge takes the flight pack(s) down to 3.8v/c. If you flip the batteries and charge you can run into two issues: 1) The source voltage might be too low for the voltage regulator to upscale to match the output voltage. i.e. It can make chargers give up if they have to feed a high voltage/high amperage output battery with a low voltage/high amperage input battery. 2) There is no way to govern the correct stop point for the input battery (other than to use input profile settings which has its limits), this is the one you're trying to get into a desired state of 3.8v/c. The profile will simply charge the output battery to the configured state of 4.2v/c. If your output battery is the big one, that will kill the input battery. The whole point of all of this is which pack is the focus of the desired outcome. If we want the flight pack reduced to storage, the desired outcome is 3.8v/c therefore, it goes on the output side in regen storage which can be configured to reach 3.8v/c. Any more simple questions???? ;)

[@FL_Engineer]

@@RCVideoReviews I think you covered it 😅

[@RCVideoReviews]

@@FL_Engineer It was an excellent question. My knee-jerk reaction was "hmmm....good question."

[@ViktorSolenoid]

@@RCVideoReviews Excellent review as always! Keep the good work. I was wondering the same thing and I have an answer now. Just one more thing - do you possibly know what would happen if the battery on the input side gets fully charged? I hope the charger will stop on time.

[@polishguywithhardtospellna8227]

I think the value of this charger for someone, that has very few models is massive. If you have 10+ models and electronics fail or missbehave, you can swap parts for diagnosis. With few models, you're guessing and buying replacement blind. It's so great, I think everyone should have THIS model, and some dual or quadruple as addition if needed. It sucks toolkitrc multi battery chargers do not have M7's features. My plan is to buy used or as new small AC bricks, that charge through balance port, with 1-2A output, to charge multiple at once, and potentially finish with M7, or storage charge with M7 after brief multi charge with all chargers. Those bricks are so cheap and provide redundancy, while I won't use more than 3s. If a channel fails on a two or quadruple charger, you're stuck with it-shucks to bin, sucks to loose channel, hard to sell half failed charger. One thing no one mentions, is despite the great value in functionality, this charger requires BIG additional investment, especially for users, that don't solder. All the necessary and useful extensions it needs, while providing none, will be very costly. That is something, many happy buyers will be disappointed about.

[@sebastiansombra]

The regen function is a cool feature, I can't remember how many times I ended up with full charge batteries after a day of flying. Only downside I see is that it doesn't balance the battery that is being charged.

[@RCVideoReviews]

No it doesn't. That said I don't think any regen chargers balance the source. That might be a good product upgrade because they don't check balance under load either which wouldn't be a terrible idea.

[@JS-te4gz]

Should I remove when says fast charge done or wait until totally done?

[@RCVideoReviews]

Fast charge done just indicates a change from constant current to constant voltage so yeah leave it until it says it’s done.

[@NextLevelCode]

Hi. Can you adjust the output voltage / amperage while the output is on? Or do you have to switch the output off to change the setting? Thanks!

[@RCVideoReviews]

No, the M7 like the M8S requires output to be stopped in order to change voltage/amperage.

[@MarkJohnMorris]

Can I plug this into the wall? House electrics? Just order this charger but think I need a 240v (UK) to 12v adapter? To work this xharger. I have 2S 3000mah & 3S 2200mah batteries for my RC Car. But im completely new to this hobby 😮 thanks!

[@RCVideoReviews]

This is a DC charger meaning you need some kind of power supply like this: amzn.to/3QoWMW4

[@MarkJohnMorris]

@@RCVideoReviews thank you 😊 🙏

[@williamcox3852]

Nice video. I may have to build me just a charger bench for all this equipment. I need more room in my shop.

[@RCVideoReviews]

I would think of the M7 more as a device to keep in/near your toolbox for builds. My M8S is like that, but I think after using the M7 for a while I may switch them around and use the M8S on the desk and the M7 in the toolbox.

[@michaeld4502]

Is there a charger that will allow you to change only one cell in a pack?

[@VitalFPV]

ordered mine M7, would be grat to see how to calibrate it :)

[@RCVideoReviews]

Ok, it's not hard. I can do that.

[@benhardwick4572]

Will this charge a lithium ion battery that doesn't have a balance lead?

[@RCVideoReviews]

Not using a Lithium profile. It will complain about lack of balance info if charging with a lithium profile and no balance connection.

[@rafaelreusch]

Can you measure the battery IR, voltage etc powered by itself? (only connecting the output xt60 port?)

[@RCVideoReviews]

Not sure, I've never tried.

[@butena55]

Unfortunately, the device doesn't entirely convince me with regards to the built-in servo tester. I have discovered that digital servos cannot be controlled because they constantly flutter. If I want to test the servos of 2 retractable landing gear, which are usually connected via a Y cable, that doesn't work either, only 1 servo moves at a time . Otherwise a good device and also a good test.

I dig by M6, but changing the min input voltage etc. settings to go from power supply to battery input and back was a bit of a pain, the menus/interface and scroll wheel on this one are big improvements.

[@RCVideoReviews]

I've never tried the membrane device, but I can say the scroll wheel navigation is becoming 2nd nature to me. It's showing up on so many different devices.

[@maceliusfpv370]

@@RCVideoReviews The old one is not even membrane, it's capacitive (but only on the buttons)! Works pretty well especially for a cheap unit, unless you're trying to fumble it with your fat fingers in low light lol. I prefer the scroll wheel to either any day, especially in long menus with many selections. I was going to buy a second to build in to a dual charging case, but now I might need an M7 as well lol.

[@RCVideoReviews]

@@maceliusfpv370 I think this M7 might make its way into my field box to replace my UP600s (which have been excellent by the way) but the M7's have more gadgetry.

Is there a trick to charge only via balancing port? I have a 1s lipo with just a connector fitting the balancing port. But it says voltage to low. Thanks sir

[@RCVideoReviews]

Get an Ultra Power UP-S6 charger for 1s cells.

Hi, i believe the new firmware 2.01 fixes exactly that issue. the problem is that the powersupply function stops working. you can download the new firmware file from the official web page. if you do upgrade, please make a backup file of the original firmware file (just copy and pase it on your drive) and share it with me please. i don't use 1s batteries but i do need the power supply function so i would lie to go back to v2.00 but can'tfind the file. thanks

Hi, I bought one a couple of weeks ago but the power supply option is not working. instead of showing me the info the manual says it should, it shows me a blank screen. i believe it is related to the firmware version 2.01 that i updated as soon as i got it. would anyone that has it mind sendimg me the firmware file so i can try downgrading back to v2.00 and see if i can use the power supply option again? thanks

[@alexey_sychev]

Got mine from AliExpress and it has 2.0 firmware out of the box. Hope it is not a new revision which is cheaper and worse, as usual :)
