These will save you lots of money by making sure you know when the battery is running out of juice. I have one on my quad and the other is on my ground station. There are a few problems however: both of the alarms I got report a full battery as being 12.4V as opposed to 12.6V. Both also report differing cell voltages for example alarm1 shows voltages as being Cell1: 374V Cell2: 379 Cell3: 368 and alarm2 as Cell1: 371V Cell2: 371 Cell3: 388V while my imax charger claims the cells are in fact balanced equally. So these aren't terribly accurate. I digress; these are for alarming you when to land and that they do well (mostly). You can set the alarm voltage with the button on the alarm from 27V to 37V (I recommend setting it to 33V if your alarms also show full voltage as 124V.) Mine will sometimes remember the voltage I set and sometimes forget it when I switch batteries. Also I managed to ruin one battery because the alarm wouldn't beep even at 28V even though I had it set to beep at 33V. So don't trust these blindly also have a timed alarm running (phone watch timer etc.) in addition. For the price I can recommend them as a starter solution but having telemetry on your TX or OSD would be much more convenient.

tardas en darte cuenta que tener un comprobador de baterías es imprescindible si quieres que tus bateriás lipos duren un mínimo tiempo. este modelo además lo puedes programar para que te avise en pleno vuelo del estado de la batería. el único pero es que aguanta muy mal los golpes y que podría ser más pequeño, menos aparatoso.
