Simple and lazy person system.
I just used a "sharpie" marking pen to label the now 6 batteries used. Roman numerals on what would be the bottom side when in the charging hub. Did stick one of those DJI stickers onto the original charging hub to distinguish it from the 2nd newer hub and batteries.
Manual mode with landing at ~30% capacity has been delivering +5 to +7 minutes of flight times. 6 batteries is turning out to be enough for a good session. Plan is once the original 3 start losing significant capacity to just purchase 3 more to replace them to keep the inventory at 6. Unless DJI comes out with a sub 250gm version of the DJI FPV with a Neo size footprint.
One concern with the Neo design is the power button. Wish DJI would have copied the Avata2 system. Power on/off built into the battery v. the quad. Wondering how many on/off cycles the Neo power switch is rated for. Had to replace the momentary switch on my Spektrum roller switch. Lots of clicking that roller switch. Easy access, simple soldering, and off the shelf inexpensive part. Neo? Guessing more work if a replacement switch can be sourced. Probably no something to be concerned with. Will probably crash trash Neo before the switch wears out.
