hey does anyone know of a good, reliable external LVC?

I think this is what you're looking for: https://www.ssl-stormerhobbies.com/c...=ns&pn=NOV5470

thanks. are there any other ones besides that one? i like the novak one so im going to consider it.

hmm...what about this low voltage alarm?

No matter how many American flags they have on that listing, it reeks of being a Chinese knock-off product. There's also a difference between a buzzer/alarm and an actual cutoff.

yeah i know that there is a difference. so thats not really a good buzzer then? maybe i will just spend the cash for the novak then. also, how would i wire it up? i read the manual but i can't really understand these two parts:

Input Harness Connection--Disconnect ESC’s input signal harness from the receiver and plug it into the 3-pin header on the Smart-Stop--connect input harness with the WHITE wire toward the outside of the Smart-Stop’s PC board. The white/red/black sequence of ESC’s harness should match Smart-Stop’s signal wires soldered to the opposite side of PC board--white over white, etc.
Connect Smart-Stop’s harness to receiver throttle channel (#2), making sure wiring sequence matches the other receiver connections.

Power Lead Connection--Measure and cut the Smart-Stop’s 20G RED & BLACK silicone power leads to the required length for where it is to be mounted. Strip & tin the ends of the power leads and solder to your ESC’s RED (positive) & BLACK (negative) solder tabs--RED power lead to RED (positive) tab; BLACK power lead to BLACK (negative) tab.
When soldering leads to the tabs, make sure you do not short any of the tabs to each other--your electronics will be damaged! If connecting Smart-Stop’s power leads to battery, its connector, or battery wires, insulate solder joints & exposed wiring to avoid short-circuits. Note: When using 4-Cell Smart-Stop with the Novak HV Brushless ESC, connect power leads the same solder tabs as the ESC’s Power Capacitor.

would i need to do both steps or would i pick only one?

You have to do both - the esc connection is how the smart stop pulses the power to get your attention that voltage is low and smart stop has to have power.

okay thanks.
