Great for monitoring battery level in my RC plane
Works as intended. Beep is loud enough to hear from far away.

Great product
Really inexpensive way to check you rc unit’s battery. Quick and simple to use.

They work like advertised
So far no problems accurate and they're pretty loud

Works great, no false alarms
This is a great tool for knowing when you’re li-po battery voltage is getting low. The alarm does NOT stay on if your voltage dips below the set point momentarily. If your cell voltage comes back up, the beeping stops. Works awesome. I’ve got cars that go into low voltage cutoff way too early so I put the ESC into NiMh mode and use one of these instead. Just ziptie it or use double sided tape to fasten to your chassis and plug in your balance connector to the meter. Set your alarm to 3.4v and you’ll enjoy much more runtime without risking damage to your batteries. So worth the $10 for 2 of these. I’m ordering another pair.

Great product for use with lipo batteries. Alarm is super loud. Easy to set up. Holding up well!

Display is bright and easy to see
I use this for an RC plane that doesn’t have telemetry. The alarm is easy to set and easy to hear from inside the RC plane. It gives me a little more flight time, knowing that I’m not going to hit LVC before hearing that alarm, with enough time to land safely. Affordable and works well.

Very easy to use with decent read out and fairly loud alarm
These 1S to 6S LIPO battery monitors work well. With the two button setting button it easy to set alarm thresholds. Only down side is it is difficult to align the balance plugs with the unshrouded pins. The alarm is loud enough to hear 10 ft. away. They are small and lightweight which would make them useful to monitor battery when a drone was in flight if the alarm was louder.

Great device for Lipo batteries
Works well to monitor total and individual cells while RC is in use. I’ve used it in buggies,boats,and planes. Voltage Alarm is great to have especially for boats and planes. Can hear beepers a solid 100 yds plus away on boat or plane giving time to get back before cutoff. I set mine for 1.6 volts per cell particularly in aircraft without telemetry. Only issue I have is mostly on my 4s and 6s jets, the beeper sometimes goes off under full throttle climbs (inrush) as voltage temporarily drops below set value and stays on even though cell voltage returns higher after the inrush burst.
