of the same nominal voltage.

• Batteries of differing voltages cannot be used.

FEATURES

• Easy to Install – The electronic isolator does not require any changes to the vehicle’s

existing wiring. It can be fitted to all 12V vehicle types.

• Priority Charging for Starting Battery – Ensures that the starting battery is fully charged

before connecting the auxiliary battery in parallel.

damage, which could occur due to a short circuit in the wiring.

• Surge Protection – Provides surge protection for vehicles with electronic ignition/management

systems.
