This nine gram unit is only $3.99. It can be used to check the voltage on a lipo. It also shows individual cell voltage and will sound an alarm when you reach your cut-off voltage. I keep one near my charging station and I also use them in the air. I have even used one on the dash of my FPV truck. All I have to do is pan the camera down to check my battery voltage. My main use is as an alarm on my planes and on my multirotors. It is a great added security to have an audible alarm when your battery is low.

I got excited about this alarm & bought several from HK that look just like these. They work, but are hard to hear if someone is flying a slimer or gasser. A great idea, just would like for it to be louder.
Hopefully, these are better than the HK ones.

Those look identical to the ones I get off of ebay or amazon.
They are great. You can set the voltage to come down with 20% or so of the pack capacity left, which I think gives you better battery life.
Nicer than just using a timer in that sometimes I use a lot if throttle and sometimes I just put along. Also if the alarm starts going off early in the flight, I know the pack is developing internal resistance and it's time to think about ordering some new batteries.
Also excellent for the lipo packs I use on my glow starter- which doesn't have a LV cutoff.
