V. Product Function Introduction:

(1) output short-circuit, anti-reverse connection: the product has an output short-circuit, reverse battery tips (reverse 1-2S detection, detection of reverse reverse connection reverse connection or short circuit, LCD segment code display "ERO", the buzzer and the buzzer and issued a drip drip drip ringing, the detection process will not be due to the reverse or short-circuit caused by the product is damaged), and the reverse connection. After microprocessor program processing, there will be no reverse connection spark phenomenon occurs;

(2) Charging overcurrent warning: when charging the battery, if the battery is abnormal, resulting in charging voltage is too low, when the charging current is greater than 20A or more, it will trigger the undervoltage alarm (LCD segment code display "LOU"), at this time, it will automatically disconnect the charging to protect the battery and its charger, to avoid abnormal situations. 

(3) Charging memory function: the product has a charging function memory mode, the product power-up mode defaults to the state mode used before the last power-down.

(4) Seven-stage charging: the product has seven-stage charging function (the seven stages are: desulfuration, trickle charging, constant current charging, constant voltage charging, battery power detection (the detection stage only displays the voltage and temperature, and the power grid effect is the same as the restoration mode), compensatory charging, and float charging), and the charging curve is shown below:

Note1:Motorcycle battery mode only has 6-stage charging (remove desulfuration)

Note2:LiFePO4 battery mode only 6-segment charging (remove float charging)

(5) Battery power detection: without access to the AC input voltage, the battery clamps clamped on the positive and negative ends of the battery (red positive and black negative), you can display the current and voltage parameters of the battery in a timely manner (digital tube display data: voltage and ambient temperature cyclic display, the power grid according to the detected data in the form of a percentage of the form of display, the first time on the power of the 6S self-check and wait for the 6S did not come to the temperature display, 6S to reach the temperature and voltage cyclic display)

(6) winter and summer mode: during the charging process, detect the ambient temperature, adjust the charging status of the product at the right time, to ensure the battery life and charging safety, winter mode: LCD segment code display snowflakes, summer mode: LCD segment code display the sun

(7) over-temperature protection: the product has an over-temperature protection function, the product detects the temperature is too high, it will start the over-temperature protection program, when the temperature returns to the normal value, resume the initial charging state.

(8) overcharge protection: the product has overcharge protection function, to avoid overcharging lead to battery life decline, enhance the reliability of charging safety (maximum charging time default 15.5-16.0H)

(9) charging voltage self-test: automatic self-test after the battery charging is completed, without human switching, self-test passes into the float charging, and vice versa into the compensation charging, compensation charging is completed then into the float charging

(10) key anti-trigger: the product key to put the wrong trigger, product charging start timing, 30S after the key self-locking, can not be triggered, clip off the key can be unlocked (AC no input, clip clip in the battery no-load self-test state, the key lock, access to the AC input voltage before unlocking)
