I agree with you.The capacity controller works like a fuel gauge in your car.The voltage alarm only gives voltage readings of each cell.But,it's good as a low voltage alarm in the model.

I just found your video today. Very detailed. Thank you. I have purchased the same capacity controller It came without any cable and I am blind now. Please help me to get up and walk. I want to use this for my 4X 3.2 v lifepo4 batteries. How do I get a cable and how do I connect my lifepo4 batteries and capacity controller Thanks a lot for your time for coming to help me 😊

They're both great to have for completely different purposes. One in the plane and one in the flight box.

Have this 2 items work good..small one use only as an Lipo alarm..the checker got downside no balancer mode.. for their price its reasonable..great explanation mate!

Just got my tester...thanks for advice🇬🇧👍

Fantastic, I ordered one because they seem like the same price as a beer now. But wasn’t sure how it worked . Now just gotta be patient for the mail service.

I recently got the Digital Battery Capacity Checker after seeing this video and this device can even balance the lipo battery cells by pressing the Type button for few seconds and selecting the which cell to balance. Definitely a useful visual device and better than that crappy loud beeper. Thanks for the useful information and definitely must for those who use lipo Batteries in RC Toys, Gel Blasters and Drones

Hi first time owning battery I noticed the wires are not just black and red On the battery in the video are the black wires the ground

For Airsoft players who uses AEG guns, I really recommend this because if you dont know if your battery is full or not it would be bloated or lost in Capacity

Hi great video very helpful I’m looking to fit one of the small alarm monitors in my rc plane once the battery volts are set when you put a new battery in the plane will the monitor still remember the alarm settings or do you have to reset after every battery change I only ask as I might have to mount the alarm away from the battery connected by a brace cable hope you can help John

I use both testers with my quad. Be careful with the small one. Position it also with the LCD facing your pack. Had a hard crash(it dropped from about 50m) n the pins on the back under the instructions pearsed through itsown heatshink n two layers of heatshink I put on the pack. But both worth every cent. Thanks Matt. Great video

at 8:10 Your manual for the Capacity Controller appears to be better, mine says: "NEW Balance Function: Long press the first key, LIPO/LIFE/LIIO will blink, says it is in balance, balance process according to the second button can view each battery voltage, balance is take the batter in the lowest section as the benchmark to discharge balance" (I'm here because I wanted to see how the "balance function" works haha)

Morning Jim, same here they both come in useful, Matt

Hi Matt I also have one of the GT battery checkers and they are perfectly ok but not as accurate as the Celldiag 6, high accuracy alarm battery indicator. I did a test with both of the above by checking them on a pro battery charger and the Celldiag 6 was much closer to the true voltage. They are a little more expensive but worth it when you consider the investment of what you are flying. Happy New year and happy flying.

Should I spend the 8$ on hrb brand one just like that G.T. Power or 2$ one from China? I'll probably get the black one with lcd screen for 8$ on Amazon

I got several of the small ones and I own a Turnigy brand of the large one. Also I own two multi meters. Problem is that I get a different reading from them all. Don't know for sure which is accurate or not.

These capacity testers are a must have for anyone who is into FPV.

What percentage is good to have the batteries in storage mode

bought one:there a must have .. :>).. luv it!

You can discharge all those different type of batteries too right?

Try flipping your battery upside down and connecting that way.

All so works as a servo tester!!😁👍👍💯

this are two different testers/alarms.the small one fits into a car or boat ;when one of the cells go low it start beeping. i dont see you driving /navigating with the big one in jour plain or car/boat

One thing to add, the one bigger battery checker you used does not show individual battery cell life status, that is the only glitch, I bought a Venom battery lipo checker and it can read and show each cell status so you know if an individual cell is over charged or low on charge which can lead to battery swelling & failing

@MirzaKhalid

You answered all my questions. Thank you!

good information. Hey, Can we set low voltage alert in that Big Black one (G.T POWER) tester too?

The large one can't read a 1s battery for Whoop flyers but I too have both.

Did you test the new one on a micro meter same as the old one?

Can I check battery cycles with the Capacity Controller?

Matt, take a look at the ISDT BC8S battery checker!!! Talk about cream in your coffee, it does everything and has beautiful real digital displays, is much smaller than the big capacity checker that we all have been using. Really, go watch a video on it and then buy yourself one and figure out a way to put it on a lanyard around your neck or similar method to keep handy. Next week you'll be putting up a video on it.

He do you put a small tester and alarm in a plane that is 1 cell. 2. At what percentage is it unsafe to put the plane back in the air.

So what percent should a storage charged battery be at mate 😀

You can Get to the menu if you hold in cell or mode button

Hi Matt, They are very good, but there's an even better version for fixed wing flyers, called CellMeter8 which has an inbuilt servo tester as well as discharger/balancer and does 5 chemisty types, around same price, looks same but it's blue. Cheers

It’s not rocket science look at each cell voltage the should all be even if not for sure u have an issue with either low battery or bad battery.

Those things are crap. Very inaccurate. Usually, here is a reading difference of 0.1 to 0.2V which is huge in my book. The best thing you can do is to use a decent volt meter to measure the voltage of each cell with a home made two pin cable. Some of those types of readers are decent but they cost 40+ bucks. Why not buy a 70 buck multimeter to measure accurately voltage, resistance and current of not only your battery but also stuff in your house as well !?

I bought the simple alarm because on my battery it has led's to indicate me if it's flat or on 20%, 30%, 50%, 70% or 100%. Btw the brand is called Hacker. It's a german brand just saying.

@m.g.v.

6 жыл бұрын

The reason I bought the alarm is that Hacker says to put an alarm at 3,3 V and not 2.7 V.

3.8 is 1/2 charge if your alarm is set at 3.5 and your full charge is 4.1 or so. You don't need those fancy modules if you can add and subtract. Jeez, you make it sound like calculus. 3.0 per cell is damage time, don't let your battery EVER get below that or it can be ruined, even during high throttle flight. Too much tech crap can spoil all the fun of just flying.
