Lipo in transmitter may have auto-cut protection circuit

Protection IC board of each cell, autocut at around 2.9-3.0V

發覺有D發射鋰電居然每cell有安全ic電路板, 降至2.9V 會自動cut, 保護粒cell過放, 但支控電壓顯示9.4V , (e.g. each cell ~3.2, 3.2, 3.0) , 有機會支控未beep(9V alarm) , 粒電保護circuit 會cut 電, 支控即死建議

1) 用到 11V 要收手, 但會唔記得 (cause slow discharge will deeply drain the lipo, unlike we use for motor)

2) check 發射鋰電 有冇保護ic電路板

3) set 高D Voltage alarm , 如10V,DX7 在隱藏menu 可set
