Dual Battery Isolator Kit, 250 Amp, 12V/24V Smart VSR Relay Switch
Dual Battery Isolator Kit, 250 Amp, 12V/24V Smart VSR Relay Switch
This dual battery isolator kit links two batteries so the main battery stays charged while one alternator serves both. An LCD shows the voltage of both batteries in real time, and an emergency button lets you start the engine from the auxiliary battery if the main battery is drained.
The kit includes a cable for lithium battery connections and mounts with four fixing holes. On 12V systems the display reads 13.5V to 16V, and on 24V systems it reads 27V to 32V. The unit disconnects when voltage falls below 12.5 V, with a 5 second delay during automatic connecting and disconnecting. Its compact body suits RVs, boats, campers and similar vehicles.
