Dude, cycle the battery. Drain it until it turns itself off, let it cool, then fully recharge it.
0% does not mean it's completely flat. The battery will switch off when the lowest cell reaches 3.3v, this is safe to do.
Thank you. I had planned on cycling them anyways, just to be safe. I just found it odd that I was only getting the warning on the Android device while the ipad shows no warning at all - and i know I have the latest version of the app on both devices.
If you don't mind me asking a follow up question, (this is another thing I haven't been able to find a clear answer on) what is your preferred way to drain the batteries? I usually fly, then keep it on in the inspire until the app shows the battery is 0%, let cool, and recharge. I know the TB48 and TB47 batteries have a residual charge in them so it's not possible to over-discharge (or so I've read), but I seem to see draining to 8% is the magic number.
These batteries came with a refurbished Inspire, and each has been through at least 40 charge cycles, and I have no idea if the previous owner cycled them properly or not.
I flew with the batteries today and did notice a sharp drop in voltage after take off - Im not sure if this is because of the cycling issue or if they're just at the end of thier life. Regardless, I drained them down to at least 20% - I didn't have the time to run them down completely. I plan on draining them fully tonight.
I just want to extend the life of these batteries as much as possible - can't really get them anymore, and, of course, be safe. Dont need a battery failure causing a crash.
Thanks for your input. |
