Optimate Lithium Battery Monitor and Charging Lead 0-127

• Permanent ring terminal harness connects directly to 12.8V and 13.2V lithium (LiFePO4 / LFP) powersports batteries for continuous status tracking.
• Microprocessor monitor automatically switches between stored battery state-of-charge check and live vehicle charging system diagnostics.
• Multi-color LED display shows remaining capacity from full to empty while drawing less than 0.2mA of current during storage.
• Active charging mode verifies regulator/stator output between 14.2V and 14.5V with visual warning alerts for overcharging conditions.
• Standard heavy-duty 2-pin SAE connector includes an integrated weatherproof sealing cap to shield electrical contacts from water and trail grime.

Keep close tabs on lithium battery health and charging system performance with the O-127 lead. Designed specifically for 12.8V and 13.2V LiFePO4 / LFP starter batteries, this harness stays attached directly to your battery terminals to deliver instant voltage feedback, confirm alternator or stator output, and provide a heavy-duty quick-connect port for your charger.

[OVERVIEW]
No more guessing whether a stored machine will fire up or whether an electrical issue stems from a weak battery or a failed regulator. The integrated multi-LED monitor operates in two smart modes: a standby blink mode that tracks resting state of charge with ultra-low current draw, and an active running mode that verifies charging voltage as soon as the engine starts.

KEY FEATURES:
• Dual-Mode Operation: Automatically alternates between resting battery charge monitor and dynamic engine-running charge system test.
• Accurate Lithium Diagnostics: 3 LEDs indicate charge levels from full to empty for 12.8V/13.2V lithium starter batteries, while a 4th LED alerts you to dangerous overcharging.
• Ultra-Low Draw: Standby battery check blinks once every 10 seconds, drawing less than 0.2mA so stored vehicle batteries will not drain prematurely.
• Live Charging Test: Arrow LED indicator illuminates when vehicle charge output hits the effective 14.2V to 14.5V lithium charging window.
• Weatherproof SAE Connection: Standard 2-pin SAE charge lead fitted with an inline rubber sealing cap keeps dirt, moisture, and road wash out when riding.
