Hypertech

Hypertech makes battery management products for boats, especially fishing boats with separate trolling motor banks. eMarine carries Hypertech Battery Combiner 100 and 200 (standard and lithium versions), Trollbridge 24, 12x24 and 36 units (including lithium versions) that charge trolling motor batteries from the engine, the Hypertech Galvanic Isolator and Galvanic Isolator Plus, and a rain-activated hatch closer.

How to choose a Hypertech product

• Combiner: charges two banks from one source and separates them when charging stops.
• Trollbridge: charges a 24V or 36V trolling motor bank from the 12V engine system.
• Lithium: pick the lithium versions for LiFePO4 banks.
• Shore power: galvanic isolators protect underwater metals while plugged in.

What does a Trollbridge do?

It lets the outboard alternator recharge a separate higher-voltage trolling motor bank while you run.

Combiner or isolator?

See battery isolators and combiners for both options.

Where are galvanic isolators?

See galvanic isolators.

Are there lithium versions?

Yes. The Battery Combiner and Trollbridge are offered in versions labeled for lithium batteries; choose those for LiFePO4 banks.
