P.S: 24V 75A power switching charger mainly for the large capacity of lithium batteries, lead-acid battery charger. Charging the countdown function need to hold the function button for 3 seconds (countdown time flashing), and then time to start the countdown , each time you press the button at this time the countdown increased 10 minutes. The countdown to the longest can be set for 360 minutes, and then continue to press the function key ,will began to fall back in 30 minutes and start to increasing .( The default countdown value is 120 minutesIn the condition of the countdown, if long press the button for 3 seconds, then exit countdown , at this time the countdown time stationary position in the 120 minutes; Overvoltage protection for the lithium iron phosphate battery is 29V corresponding output overvoltage protection at (24V , section 8).
