I am too chicken to let mine hit the warning buzzer... I have a tendency to top up my lithium's... Am I correct in thinking that below 3v/cell is the kiss of death for a liPo? I mean can you let them drop to 3.3v on a regular basis without worry?
From what I read after under volting one of mine, there is no exact voltage. I read a few places that 3.4v per cell is recommended cut off point however I have read some people who let theirs go under 3v per cell.
Personally I don't want to waste money on another 5A LiPo so my battery monitor was set for low voltage at 3.6v on either cell, 3.5v was the second warning and 3.4v was critical. That gave it enough time to find the charging base and charge up (in theory, finding the charging station isn't something I've even started yet).
There are reports of people bringing LiPos back to life too but it involves very unsafe practice and I like my house not to be on fire, a battery is a lot cheaper than a house!
I just powered my mini 6 w/turnigy 2c Lipo 1700 battery.
Am I wrong in trusting my HobyKing low voltage alarm? (3.3v)
I have given it much play time with no alarm. Still performing better then my old battery packs.
Still learning about Lipos.
Edit. Richard R , I think 3.3v will b ok.

I believe 3.2v per cell is the value you will find in most ESCs that have the low voltage protection and in the low voltage alarms for LiPo batteries.
1.25 hours is a long time to charge a 1300mAh battery. I would guess the battery can handle better than 1A but you need to make sure you have a good charger that can detect and automatically adjust the charge rate to make sure you can do it safely.
@Rich's values are quite conservative, most hobby RC companies state that 3.0V is the cutoff and 3.3V is just best practice. We defaulted to the best practice value but everyone is welcome to set the low battery warning to whatever they like in ARC we just recommend that it's 6.6V (2cells in series at 3.3V = 6.6V) or higher for 7.4V LiPos
Yes I totally admit I am probably too careful with my voltages. My plan was to return to charging station and automatically charge on low power, knowing motors take a lot of energy I wanted to cover myself and know there would be no chance of dropping below the cut off point.

Thank you Zap, I will let my low voltage alarm work. I also want to see how long it will play? Steve S

3.0v is fine, as Jeremie says.
