About this product
About this product
Keep a close eye on your lithium battery's health with the Tecmate OptiMate Lithium Battery Monitor. This handy device provides constant monitoring of your 12.8V or 13.2V lithium batteries, ensuring you're always aware of their charge status and the performance of your vehicle's charging system.
Description
The Tecmate OptiMate Lithium Battery Monitor offers two automatic modes: a battery charge level monitor indicated by a single LED blink, and a charging system test indicated by an arrow mode. Three LEDs clearly display the 'full to empty' voltage range for your lithium batteries (LFP/LiFePO4/Lithium nano Phosphate). A fourth LED provides a warning if the vehicle's system or connected battery charger is overcharging, protecting your battery from potential damage. The battery charge level is indicated by an LED matching the charge level, blinking every 10 seconds with a minimal long-term draw of less than 0.2mA. When the charge voltage reaches the lithium charge range of 14.2V – 14.5V, the LED arrow mode activates, giving you a clear indication of charging system performance. Installation is simple with the permanent power sport battery lead, and the SAE charge port includes a weatherproof sealing cap for reliable outdoor use.
