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

Permanent power sport battery lead with integrated battery status and charge-system monitor for lithium starter batteries. 🔋

Two automatic modes: battery charge level monitor (single LED blink mode) and charging system test (arrow mode), letting you confirm stored battery condition or verify the vehicle charging system.

Three LEDs display full-to-empty voltage range for 12.8/13.2 V lithium chemistries; a fourth LED warns if the vehicle system or connected charger is overcharging.

Charge-level LED blinks every 10 seconds for minimal long-term drain, and the unit includes a weatherproof SAE charge port with sealing cap for a tidy permanent connection.

Compact and simple to install, it keeps your lithium starter battery monitored while minimizing power draw. ✅
