Hi, I don't think you really need that one,

if you just want a lipo low voltage alarm the cheap ones work just as well.

.
You can set the alarm to your own low voltage limits,

I set mine to 3.7 volts per cell. %)when plugged into lipo balance lead it will scrolle thu -- 1 cell voltage,-- number2 cell volts,-- number 3 cell volts,-- total volts.

Plug into balance lead any way round till it reads (it wont be damaged)

Hope this helps
