TECMATE OptiMate™ Lithium Battery Monitor — 12V, SAE plug

The OptiMate™ Lithium Battery Monitor provides permanent monitoring of your lithium starter battery and confirms whether the vehicle charging system is working correctly.

• Permanent power-sport battery lead with integrated status and charge-system monitor for 12.8 / 13.2 V lithium batteries.
• Two automatic modes: battery charge level monitor (single LED blink) and charging-system test (arrow mode).
• Three LEDs show full-to-empty voltage range for LFP/LiFePO4/lithium nano phosphate batteries; a fourth LED warns of overcharging.
• LED matching charge level blinks every 10 seconds with very low long-term draw (<0.2mA).
• Charging-system arrow mode activates when charge voltage reaches the effective lithium charge range of 14.2–14.5 V.

Designed for long-term installation, it keeps you informed of battery level and warns of overcharge so you can protect your vehicle before failure. 🔋
