Overview

The dual battery isolator kit provides adjustable start/stop voltage, compatible with both lithium and lead-acid batteries. It features manual and automatic modes – when the main battery power is low, the auxiliary battery can charge it in reverse. Its new delay function effectively avoids frequent opening and closing of the isolator due to unstable current. It easily handles complex power consumption scenarios.
