AC180P RANDOMLY TURN OFF AND ON

Hello,

I have an AC180P unit, I haven’t used it for about 6 months (I used it for about 3 months with no problem) , I left it with 70% of battery, now if I turn it on it starts to turn off and on randomly.

I have the app and signed with this email, firmware is updated:

ARM

V2087.04

DSP

V2086.02

Please help.
