Bank transferOptiMate™ Monitor is a compact 12 V socket adapter that plugs directly into motorcycle, ATV and UTV auxiliary power ports for continuous battery oversight.
The integrated state of charge monitor gives a visual status every three seconds and supports high-performance AGM and lithium‑ion (LFP) batteries, with a weatherproof sealing cap for outdoor use.
Two automatic modes simplify diagnostics: a single‑blink mode for battery level monitoring and an arrow mode to test the charging system.
Durable cable construction (18 AWG SPT‑2) stays flexible down to -40°C/-40°F, and the adapter fits standard 21 mm and 12 mm auxiliary sockets for quick, tool‑free installation.
