2 automatic modes – battery charge level monitor (single LED blink mode) & charging system test (arrow mode)
3 LEDs display ‘full to empty’ voltage range for 12.8V/13.2V Lithium batteries (LFP/LiFePO4/Lithium nano Phosphate); 4th LED warns when vehicle system or connected battery charger is OVERCHARGING
Battery charge level : LED matching charge level blinks every 10 seconds (long term draw less than 0.2mA)
Vehicle Charge system : LED arrow mode activates when charge voltage reaches effective lithium charge range of 14.2V – 14.5V (v green LED). OVERCHARGE warning activates at 14.6V+
