Battery alarms?
Just picked up a revolt 30 and ordered 2 4s 60c hd lipos from hobbyking.
Does anyone use battery alarms? Low voltage alarms.
Also has the fly color 150a esc and the UL-1 motor.
What if i got one and set it to say 3.5v per cell?
Can i hear it out in the water inside the boat. Like it would be cool to do that so i can get max use out of the boat and still be able to drive it in once i heard the alarms.

Your stock 60-amp esc in that boat has a low voltage cut-off. This will reduce the power output once the batteries are below certain voltage which gives you enough juice to bring it back to shore. Several other esc's you could upgrade to also have a similar low-voltage cut-off. No need for alarms.
A great upgrade would be the OSE Raider 150amp for $60 and get the programmer for additional $10

That is basically the same esc as the OSE raider I mentioned. I believe only difference is the branding. Correct me if I'm wrong fellas...
None the less, this esc DOES have a low voltage cut-off. If you didn't get a programming card with the boat... pick one up ($10+/-) so you can make sure the cut-off is set properly.

Here's the one OSE sells for there Raider which again... I believe is the same thing.

When it hits said cutoff, does it slow down or completely stop?Originally Posted by dethow

As long as the esc is not programmed to have NO cut-off it will just reduce power to like 20% which gives you enough juice to get back to shore.

YouTube can be a great resource. I used it a ton when starting out.
I just typed in "programming a flycolor esc" and I found this video.

I was reading up on that. Just was trying to figure out if it would just slow or stop

I should say that I have no experience with this particular esc. But several others I use with low voltage cut-off allow a small amount of power to get back to shore.
I know this for sure with the stock aquacraft 60amp and with the SeaKing esc's.
Hope someone with hands-on knowledge of this esc chimes in, but I feel 95% sure that at cut-off voltage programmed this esc will be giving you enough juice to get back to shore.

While I time my runs and my esc has a lvc, I still use one of these:

I set it a bit higher to let me know if I have a couple passes left. I can hear it if I come to a stop or a close pass by. Just a note though, they are not the most accurate and I would not solely rely on them. Plus it’s good to have something around to check your packs.

I used to time all my boats. now I use the graupner radio system with telemetry that reads my battery voltage .
