Buy the Victron Energy ArgoDiode Battery Isolator 160-2AC (2 batteries, 160 amp) online for $42.34 — a $42.34 discount (50% off) the $84.68 compare-at price. Best for boaters, RVers and dual-battery vehicle owners who want simultaneous charging of two batteries from one alternator without the batteries draining each other.
Connect the alternator B+ to the isolator input, then each battery to its output. The special current-limited energize input powers the alternator B+ when the engine run/stop switch closes — essential for modern or high-output alternators that need B+ excitation to start charging. Wire the compensation diode to slightly raise alternator output voltage and offset the isolator's diode drop.
Diode isolators allow simultaneous charging without connecting batteries together — discharging the accessory battery never drains the starter battery, so you always start the engine.
Choose the 160-2AC for 2-battery systems up to 160A alternator output. Versus VSR (voltage-sensitive relay) alternatives, diode isolators are solid-state with no moving contacts; the compensation diode addresses the voltage drop inherent to diode designs.

Versus VSR relays, the ArgoDiode's solid-state design and alternator energize input deliver dependable charging at this affordable sale price.
Connect the alternator B+ to the isolator input and each battery to an output. Run the current-limited energize input to the ignition/run switch so it powers alternator B+ when the engine runs — required for many modern and high-output alternators.
It slightly increases alternator output voltage to compensate for the voltage drop across the Schottky diodes, so batteries receive a full charge.
Choose the 160-2AC for two-battery systems with alternator output up to 160A — common in boats, RVs and dual-battery trucks.

Diode isolators are solid-state with no mechanical relay to fail, and the energize input plus compensation diode make them a reliable, affordable choice for alternator-charged dual-battery setups.
Installed between my alternator and dual batteries in the truck camper. House battery charges while driving and the starter battery never drains at camp anymore. The energize input made wiring simple with my alternator. Solid, heavy, and clean install.
The Schottky diodes have a lower drop than old-style isolators, but it's still there — my house battery charges a touch slower than with a relay setup. Trade-off is total isolation and no moving parts to fail. Happy overall.
I wanted something with no coils or electronics that could fail in the outback. This diode isolator is basically indestructible. Wired it in with the energize input on my Land Cruiser, and both batteries charge from the one alternator without cross-draining. Two years of corrugated roads and it hasn't missed a beat. If you want set-and-forget, this is it.
Functions as described and build quality is excellent. Just be aware of the inherent diode voltage drop — if your alternator doesn't have a smart regulator or the energize input wired properly, you may end up with undercharged batteries.
Starting battery and house bank both charge off the outboard's alternator now. Install took an afternoon and it's been trouble-free for a full season.
Under sustained alternator output near 160A the unit gets quite hot and needs serious heat sinking and airflow. Mine cut charging briefly on a long drive. Works, but undersized for my setup.
