Nothing new here, like this thread of huppe Tested batteries for fast dropping down in voltage But interesting to see the behaviour of the battery and voltages. I knew this would might happen, so I tested at 30 cm of ground. aprox 70% of batteries like one week stored. Firmware 1.4 Before starting engines After seconds Voltages Then it got down to 2% in seconds and landed, something like 3.4 V. After hours of rest, interesting to see the voltage and the remaining percentage, not talking at all. Should I recharge these batteries normally, at 100% and fly like nothing happened? Thoughts?
