“These are fairly accurate and allow me to run my plane until the voltage level falls to my preset value (3.6-volts/cell). The lack volume controls so it is hard to hear your individual device when flying with other pilots.”
“I never used battery voltage alarms until a friend suggested this one. for under $10 you cant go wrong. It is very light, measures 1.5 x 1 and is relatively simple to use. The hardest part to understand is programming the voltage alarm, but push the button and play with it a bit. You will figure it out fairly quickly.Once the desired voltage is set, you are done. Plug it into the balance lead on your battery, it will beep 3 times and start displaying cell and pack voltages, then put your bird in the air! The alarm is VERY loud. At most angles and flight distances you can hear it even through a foam fuselage and loud EDF jets. This takes all of the guess work out of how long can I fly and in those rare instances that you forget to set your timer, no worries, listen for the alarm.Every flight I do now has this little beauty loaded and plugged in. I have been able to extend my predicted timed flights and a few times it has saved me from a crash as I loaded a dead battery into the plane by accident.I will never fly again without this plugged in. Everyone should have this in their planes as part of typical flight equipment.”
“I bought the 1-8S LiPo Battery Voltage Checker with Low Voltage Alarm a couple of months back. Worked great at first, got a reading every time I plugged in one of my 2S or 3S LiPo batteries. Haven't used it all that much, but lately it's hit or miss, sometimes I get a reading fine, sometimes I get nothing, not even any lights, it's just dead. It's not like you can use this thing wrong, just push the balancing plug all the way in. For the price paid, it's not worth it to ship it back for a replacement, will just try another brand.”
“OK, so my last writeup I laid all kinds of praise for the battery meter. I had not flown it then. I flew it on Thursday for the 1st time on my Visionaire. What a rush. It worked fine for the first 2 or 3 minutes. It then began to beep. I landed and replaced my on-board battery. I took off and after 15 or so seconds, the meter started singing again. I don't know why. The meter was set to 3.5, I had 12.38 volts per a second watt meter, and the battery had perfect cells. I dunno what caused it. I still like the meter, just not as much......any suggestions would be apreciated.”
“I just recieved my voltage alarms about 45 min. ago. I LOVE IT ALREADY. They are extreamely easy to use and yes, they are LOUD! I havent flown one yet, but I hope to do that tommorow. If mother nature allows (50% chance of rain and wind gusts to 25), I hopefully will. I just hope our weatherman is as good as usual...WRONG! :)”
“Thank God I got one. Saved my plane on the first day. I took off circled a few times and easily heard the alarm. Immediately landed and checked my battery. One of the cells went bad. I recommend this to all who value there planes”
“Save your planes...fly with voltage alarms. I've lost planes to failed batteries. Take the guess work out of it. Use Voltage alarms. 2 plane have been saved this season...one of them was my eflite twin otter. 2nd flight this year and the voltage alarms went solid on takeoff. Brought the plane down immediately and a cell had failed in one battery.Voltage alarms let you change your count down timer to count up. You wont be guessing how long you can fly. I even go on marathon flights with some planes and see how long I can fly it. My Parkzone P-47 with a voltage alarm, flaps in 1st position with a fresh 2200 3s and me flying at half throttle or under the entire time stayed up 22 minutes 15 seconds. Not typo.I set my alarms @ 3.5 volts. The cells will drop below 3.5 under load and the alarms will sound. When you back off throttle the alarms will stop. I wait for solid alarms and I'm .3 above LVC.It's to the to the point I don't fly without these. I've bought 4 from Motion RC in total. One was bad and Motion replaced it no questions asked. My buddies at the field borrow these and forget to return them.Great product! Don't fly electric without it. Not if you like that plane.”
