Four independent ISM charging circuits. The Battery Tender® WaveCharge 4-Bank is the complete on-board charging solution for boats and vehicles with complex multi-bank electrical systems — delivering 3 Amps per bank simultaneously to up to four separate 12V batteries, each running its own ISM (Infinite Sequential Monitoring™) cycle with its own chemistry profile, independently.\u003c\/p\u003e\u003ch3\u003eFour-Bank Charging for Marine and Automotive Applications\u003c\/h3\u003e\u003cp\u003eLarge powerboats, extended-range cruisers, overlanding expedition builds, and custom commercial vehicles running four independent battery banks need four independent charging circuits. The WaveCharge 4-Bank handles all four simultaneously with no output sharing and no inter-bank interference. Each bank charges at its own rate, in its own stage, at its own chemistry setting — exactly as if each battery had its own dedicated charger.\u003c\/p\u003e\u003ch3\u003eFull 3 Amps Output on Every Bank Simultaneously\u003c\/h3\u003e\u003cp\u003eNo bank divides its output with any other. Four independent 3 Amp circuits run simultaneously at full output regardless of what the other banks are doing. A bank in bulk charge recovering a depleted auxiliary battery operates at full 3 Amps without reducing output to the three banks in float maintenance. Complete independence across all four banks at all times.\u003c\/p\u003e\u003ch3\u003eMulti-Chemistry: Lead-Acid and Lithium Per Bank\u003c\/h3\u003e\u003cp\u003eEach of the four banks has its own chemistry selector. A boat or vehicle running two lead-acid banks and two Lithium banks configures each bank independently — the correct ISM profile for each chemistry on each bank, all running simultaneously at full 3 Amps output.\u003c\/p\u003e\u003ch3\u003eISM: 4-Stage Charging on All Four Banks\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitialization\u003c\/strong\u003e — Individual health check before current flows on each bank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBulk Charge\u003c\/strong\u003e — Full 3 Amps output per bank independently restores depleted capacity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbsorption\u003c\/strong\u003e — Current tapers per bank as each battery approaches full charge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloat Maintenance\u003c\/strong\u003e — Correct protocol for lead-acid or Lithium on each bank, 24\/7, indefinitely\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCompatible per bank: 14Ah to 100Ah at 12V.
