Power sport battery cable with built-in battery and charge status monitor for lithium 12.8V / 13.2V. Monitor the charge of your power sport vehicle's stored energy lithium starter battery or check if the vehicle's charging system is functioning properly. It features two automatic modes: battery charge level monitor (single flashing LED mode) and charging system test (arrow mode). Three LED lights indicate the charge level (from charged to discharged) of 12.8V/13.2V lithium batteries (LFP/LiFePO4/nano-phosphate lithium). The fourth LED indicates when the vehicle system or the connected battery charger is in the battery charge level mode, with the corresponding LED charge level flashing every 10 seconds (long-term power less than 0.2 mA). The vehicle charging system activates the LED arrow mode when the charging voltage reaches the effective lithium charge range of 14.2V-14.5V. An overcharge warning activates at +14.6V. It also includes a port SAE charging port with a waterproof cap.
