    I've been finishing my runs and my LIPO's have been at 3.5v after LVC. I think this is too low for the long term life of my batteries. I put this together and set it for 3.5v. You have to waterproof it as the least bit of water makes it think you have more cells than are actually connected. The alarm is pretty loud and I stop driving when the alarm stays on. My LIPO's now finish 3.7-3.8v. I feel better about it.

    @Paulie I agree, those alarms are well worth the couple bucks for the added security. You make a good point about the waterproofing though and I've got a bag of 20-30 and wondering if Corrosion X would help with waterproofing as it's done for many other electronics.

    Lets find out! :D

    i have about 6 of those. 2 read the same as my venom lipo alarm. The other 4 show different values.

    I bet it would work, but you can't cover up the 2 little piezos or you will never hear them. I did that at first and I could not hear those little beepers, even though they are pretty loud. I've run them in my DJI quad and you can easily hear them at quite a distance. I've been running mine in the snow and I imagine that the water will funk them up eventually. At about $1.00 each from china, it's no big deal.


    How far off are you talking about? I must have lucked out and the one I am currently using matches my charger readout.

    I don't remember the exact numbers off hand but it was roughly .5 volts off either way

    Technically it's called a lipo voltage checker with alarm, and they're sold all over the place

    LVC (Low Voltage Cutoff) is the program perameter within the ESC that senses voltage at a predetermined point and cuts power to save the battery from potential damage
