    Loud enough to hear it on rc plane from cca 100m away. It saved my bixler 2 once when I used damaged 3S LiPo. It was inside the fuselage and I heard it on time. It would be good to somehow disable connecting of connector in wrong way. But it is not so critical as it can't be damaged that way. Too loud when connecting to the battery. Suggestion for improvement:... Read more

    This device is a small, and very lightweight alarm signal stuff (ideal for planes, helis). Indicate all of cells with separeted leds: one green for good voltage, one red for undervoltage - pro cell. Not adjustable level for switch on buzzer/lighter, but it fix 3.3V/cell - its good for save LiPo battery cells. I cannot tried with 1S, 2S LiPo batteries;... Read more

    Saves you from smashing a model to bits when the battery runs out, small and light weight, it has led's as well as a beeper. It measures and displays the status of each cell, Red LED's on one side and Green LED's on the other. Took a while before it started working for some reason, I thought it was faulty to start. Plug it into the battery charge socket,... Read more

    Loud makes it possible to hear it far away on the quad. At the moment i got a not to good 3s lipo. So it feels safe to have it as a reminder when to land. Shows which cells that are low battery. Beeps really, really loud when you plug it in. Sometimes it's hard to see the leds Just heatshrinked casing on the pcb, so it's not weather proofed Hold a finger ... Read more

    Very loud and very easy to interpret. It's easy to turn the connector around, but the whole thing is protected against that. Although this hasn't happened yet, the soldered wires may poke through the shrink wrap after extensive use. I haven't seen that happen yet, though. Green means "the battery is fine" Red means "the battery is low&... Read more

    - more or less appropriate price - good quality - satisfying dimension and wight - can be used even for 2s, works fine - could be louder - can be easily connected with the wrong polarity Can be easily connected with the wrong polarity, so be carefully. Unlike some other similar utilities, this device monitors each cell LiPo battery individually. Reports ... Read more
