Hi yes they do but I got some lipo alarms off E-bay that have 2 horns on them and are very loud and they go off before any of my lipo LVC I like these best.
See here:
sweet those bussers looks like a nice addon for a lipo shield sinse it buzzes 0.1v before the lipo shield comes in :)
Actually they come on much faster than any LVC i have or have in my ESC's and some of my ESC's have a setting of 3.4V cut off...after trying these i don't run any lipo without them and there so loud you can hear them when sealed inside a boat when running on the lake!
If i recall i tested when they come on and it was 3.5V cell
:p What go faster that's what I like to do! Custom RC radio steering grips WWW.PPRSLOTS.COM
your battery voltage wil get back up on voltage ones you off the trothle. but it say on the ebay site that they come in at 3.3V were the lipo shield come in at 3.2. but i think it might be a good idea to run both so ease the load on the batteries :)
