    It's loud enough (especially if you use it on RC models). It's very simple to use, just plug in any 2S to 8S LiPo using the balance connector and you're set. It displays the voltage of all cells combined and each cell individually. The display is clear enough to read it from a small distance. On my scale ... Read more

    Excellent product. I am surprised that the device recognizes the type of battery, show the total battery voltage and the voltage of each cell individually. The speaker is very loud so there is a possibility that you do not hear the alarm in the RC model. I have not found any deficiency in this product ... Read more

Need not necessarily be connected to model airplane, you can check the battery at any time. It's a must have for LiPo's, works with Lipo batteries ... Read more

    Clear concise read out for overall and per cell voltage. Easy to understand and set battery alarm. Small enough to tuck away into a model and connected to a battery while the model is in use - currently used on a quadcopter. Can be hard to read in direct sunlight, however cannot complain for something ... Read more

    Very handy and precise LIPO monitoring. Easy to connect to the balance wires. Beeper makes a lot of sound when you first connect it to the battery, and then alternate between cell voltage (each of the cells individually), followed bij displaying total voltage. None Before connecting the lipo balance ... Read more
