^Most of those types of ones don't beep until 3.2 V, way too late if you're not absolutely hammering the pack.

This all very well but for 2200 batteries at $9 each why worry. Set your timer at 4 mins and after flying check for the 80% rule. If you have mAh left increase your timer. Do this until you have the flying time matching your 80%. Don't stress about it until you are paying $240 for a battery.

Look at this video - and then go buy 2 or 3 or 4 at this link. They are $2 and work great!

Unfortunately, the OP says he has no way of measuring. That's why i suggested simply running it down once and basing off that.

The one that I have and the link I posted is one that ranges from 2.7 all the way up to 3.8v..

You need one of these.

I check my batteries before (I have been known to fly with a used battery) and after each flight.

Sweet, I found the same one really cheap. I was just wondering, is it hard to notice the buzzer, does the cell rating (S) matter, and do you have to adjust anything or does it come stock at a good voltage? And one more thing, my heli is coming tomorrow (Can't wait!) and I just want to use a DVM until the buzzer comes. Where do I test the power from? The main two wires? Or one of the small leads? Thanks for all your help and sorry for bothering you so much

I wish they were $9. They're $15 apiece. It's cheap but I'd rather put that money towards upgrading the heli.

hey, your rates will go up if you keep bumping around

i've seen those zippy on hobbyking at less than $10...woot!! i think it's a deal...why worry about degrading, if it lasts a year, which it will under normal use....and when you can't fly...get a couple new one's and recycle old. done.
