Question regarding battery

I just bought a bug 3 quad and I've been flying around with a 2s battery I just ordered some 3s batteries to try to get more power out of it my question is what voltage will I get the low-battery beep at since its meant to run 3s batteries I don't want to kill my battery thank you

All lipo cells have a minimum of 3.7v
& a maximum of 4.2v,unless it's a Hv.
Best not to exceed 4.2 as this is bad for a lipo, same with running it down to below 3.7v. So a 2S is two 3.7v cells =7.4v
3S = 11.1v.
A low cell is 3.7v & when not in use I store mine @ 3.8v. If you have a decent balance charger it will do it for you.
My imax will store & charge to the correct voltages. Get one if you haven't.
Your battery will last longer with one of these against one with a led that balances but no indication as to the cell voltage.
Cell 1 could be 4.20v
Cell 2 4.11v
Cell 3 4.08v
If unchecked the cells will be unevenly run down & may never be able to even them back out. Making the lipo run out faster. So look after the buggers.

I get all that what i was asking was will the remote still alarm when the 3s lipo hits low voltage. With 2s lipos it would beep but since it wasnt meant to run 3s that where i was stuck at but i bypased it i ordered a voltage checker/buzzer ill just set it to sound when all the cells hit 3.1 volts.

Then if you got it you would realise that all cells run down to 3.7v. Which is the lowest point advisable. Cheap plug on bat alarms are programmable. But I think have a default of 3.80v.
the fcb's alarm Is programmable. So leave it on default or if like me I never let them go below 3.8v whether you have a 2, 3,4 or 6s lipo the alarm will sound on the desired voltage. :cool:

Ppl say all different things. I got Lipo's that are nearly 3 years old. Don't run em down to 3.1v, I'd say 3.5v max.
From storage voltage of 3.8v to max capacity of 4.2v gives the desired flight time. Obviously weight comes into it but they are the parameters of use.
Believe me if you run a lipo dry below 3v it's a good chance you will never get it back up. & if you don't balance them properly then you can lose a cell & not even know. Your just wondering why it has hardly any power, sag & runs out faster. Take it or leave it, you will suss it out.

Preset LVC is typically 3.2-3.3 v/cell. Yes you can run it down to 3.0 without damage, but you will shorten the life of your battery

I got a imax b6 charger that i use to balance and charge all my lipos. I wasnt to sure on the lvc like i said ive seen no less than 3volts but i wanted to get a second opinion

I fly a Bugs 3 on 3S, and you can't trust the beeper. It will start beeping about the time the quad hits the ground. Use a timer and learn the flight time on your 3S batteries. You will probably also find you don't like the way it flies on 3S with the stock props. I'm using Dal 6045 tri-props, which is what most people are using, but I'm not convinced it's the best choice. It flies great, has tons of punch, but the tri's shorten the flight time a bunch.

I'm just going on experience with Lipo's I use. I wouldn't. I lost quite a few & cells, running that low. When I first started & since, now I try not to go below 3.7v I still get 6min no sag after a year or so of use. It works for me & I'm sticking to it.
Is anybody getting the same use off a lipo that's being run below 3v.? ?
