0-150 Amp Ammeter

Ferris 0-150 Amp Ammeter
BEST SELLER! A low cost instrument that monitors your High Output Alternator or Battery Charger. It comes with the shunt, wiring, terminals, hardware & instructions for easy installation. Replaces your existing alternator ammeter. Fits standard 2” cutout.

Echo-Charge
A simple, affordable means of keeping your starting battery fully charged, but NOT overcharged from any charging source. The Echo-Charge works perfectly with alternators, solar, wind or water powered generators or with conventional shore power chargers. The Echo-Charge monitors a starting battery’s state of charge and supplies just the right amount of charging current from the house bank, so you’ll always have starting power to spare! It contains logic, so it knows when to charge and when to stop charging based on the starting battery’s charge level. It eliminates the need for isolating diodes.

Battery Link
The Battery Link is a 100 amp, 2 bank automatic parallel device that senses whenever a charge is being produced. It then connects the 2 banks together so both banks will charge. When the charging stops, it separates the banks. Fully automatic operation, without a voltage drop! The Battery Link is best used with similarly sized battery banks.

Heavy-Duty Battery Isolators
Battery Isolators supply charging current from alternators and other power sources to multiple banks of batteries simultaneously. The 70 Series Isolators are for use with standard alternators. The 120, 160 & 200 Series Isolators are well suited for use with PowerMax Alternators and other high-current charging sources.
