Hello,
A question for the members out there about Lipo charging/discharging, sorry if this is a common question, feel free to point me in the direction of previous posts covering this topic.
I have a stock DJI F550 and I have the following batteries to use with it:
One Hyperion G3 VX 5400mah 4S 14.8V 35C/65C LiPo
One E-Flite 4000mAh 4S 14.8V 30C LiPo
Two 3s 11.1v Turnigy 1800mah 20-30c LiPo connected in parallel
I have an Imax B6ac charger.
I would like to understand how I determine what the 80% point for each of these battery packs is so I can figure out how to ensure I am not discharging them below this point. I have seen people use a flight timer, but can I set the Naza voltage limits in such a way that it will bring the craft down before it gets to the 80% point? At this point I have been using the default voltage settings in naza assistant and flying with the 4000mah (+Hero3) results in about 7min flying time before i don't have enough power to keep the Hex aloft. I am not sure if this is the battery running out of juice or the second level of naza voltage limits kicking in. Any pointers?
Also would like to understand the maximum safe charging current settings for these packs. My charger maxes out at 5amps, can I charge both the 4s packs at 5amps without worry? I have been charging the e-flight at 3-4amps and it has not been warm to the touch yet.
Thanks,
Sin
