Light Batteries but Weak
Lighter than other LiPo batteries of the same capacity, lead wires rubber looks very durable and soft to the touch.
I use a low voltage/voltage monitor alarm every time I fly my models, I have the threshold set to 3.5 VDC per cell to be in the safe side, after just 2 to 3 minutes flying at 75% power 2 of the batteries activated the alarm. It was a hot day, I returned days later in lower temperatures and flew again the same aircraft and the same power settings and the alarm went off again. I verified the IR and voltage with a battery tester, cells were between 7 to 9 ohms IR, that's normal for new batteries, but voltages per cell fell below 3.5 and fluctuated between 3.7 and 3.8 VDC per cell.
I have batteries 3 to 5 years old that in comparison show a relative low IR for their age and still their voltage per cell has never stayed below 3.5 VDC.
I'm giving it 3 stars to this product for these reasons.
