Screen
Short press a switch, light and display screen: voltage temperature residual capacity
current, light up after waiting for screen to go out, after 60s into power saving state
(buzzer open state, the buzzer alarm detection background), short press it again to light
up the screen.
Buzzer open state: SOC 10% or less, buzzer alarm, long press switch 3s, buzzer close and
screen OFF buzzer hints.
Buzzer is turned off, when the SOC 50% or less, need to manually by 3s starting buzzer
long (SOC testing and determine whether the alarm).
Buzzer is turned off, charging when the battery pack is SOC > 50%, the buzzer closed
automatic reset, in an open position.

Static power
Since the power consumption ≤3mA; After discharge protection ≤150uA
