A bit of reality. Our Breeze’s are nice little Drones if you understand the limits of the Breeze and use it as intended. The price point, lately, of $150, with batteries at $21, makes this a great introduction to flying a drone. There is a hidden danger: The LiPo Batteries. I am seeing more and more posts about low battery voltage and questions like; ‘can I recover my battery pack’ – as the Breeze charger will not charge the battery any longer (due to low voltage on one or more cells). So people want to know how to charge just one cell, or 2 cells, to bring the voltage up so the battery (as a whole) can be charged in the Breeze charger.
HOWEVER !!!!;
I am becoming concerned with people trying to charge a cell, or two, that is very low (0-2V or so). Playing with LiPo's is very dangerous. We seem to be missing how the cell or cells got that low to start with. It's not normal. We don’t have answers for that, but it’s not normal, and it's a warning to be careful. If you don’t know what you are doing, DON’T DO IT! (whatever ‘it’ is)
I don't know if you have looked at YouTube about LiPo fires (below are some links), but the guys I fly with (electric Airplanes and Helicopters) know a lot about LiPo batteries and they still have fires and issues. Novices (the guy that just bought a Breeze) should be aware of the LiPo potential danger. We MUST (should) all respect the LiPo technology and how much current these batteries can instantly provide; in excess of 100amps – and this will blow the end right off a screwdriver (I’ve done it – not on purpose!! And there is a very loud BANG and lots of smoke), and these batteries will catch your car on fire (batteries in your car traveling to your flying site), or home on fire (batteries charging in the garage), in an instant – this is no joke!
I only want to provide a warning about playing with LiPo’s. You need to know what you are doing, how much current you are putting in, how much current is still left in the cell or battery pack, watch the balancing time – taking too long? Not a good sign. As the Internal Resistance starts to change in a battery pack the charge times, and discharge times change. You need to be aware of this. Does your battery get hot when charging? Is it warmer than normal after a flight? All signs something is happening.
There are many YouTube videos of LiPo fires. Here are a few I picked at random.

Two things are main issues -- NOT balancing your batteries through a balancing port - meaning that any 'cell' in the battery can become overcharged - a huge issue, and shorting the battery terminals together by mistake - this causes an approximate 100 AMPS discharge - another huge issue. Keep these in mind an be safe.
