I've done a little checking on mine now after yesterday getting about a minute or two on a full battery before it all went red and began to slowly let itself lose altitude.
I still had full control of the bird but with the flashing red instead of green, and the main difference being with throttle stick released (central) it would slowly descend instead of hover.
So I presume that's the first stage of low battery sequence kicking in.
Now I haven't touched the battery since yesterday but just hooked up to the software, where it tells me it has 65% charge, one cell is slightly lower than the other 2 (4009mv, 3758mv, 4007mv), it's had 13 discharges in its life, and has 96% of its life remaining.
So how is it that it can apparently tell my macbook software that it's fit as a fiddle, but when in flight it's a different story entirely? Surely it's still the same source data coming from the 'smart' battery brain that goes to either the bird itself (which then decides it's in battery trouble) as is being sent to the laptop, which tells me it's perfect? I'm a bit confused by it to be honest.
Also, I was of the understanding that you can set your own levels for the low battery/critical battery settings? I'm obviously being stupid but can't see where.
Mine is showing on the main 'View' screen that low = 20% and critical = 15%. Doesn't seem to be a way to change these, but either way, since it currently says 65% charge, it can't have got anywhere near the low or critical levels when flying it yesterday.
On the battery page it shows a checkbox for 'go home' at Low battery level, but says nothing next to critical level?
I think I've got a lot of reading ahead of me, but if anyone has any useful tips about any of the above I'm all ears.
Everything is on the latest firmware btw.
