Three independent ISM charging circuits. The Battery Tender® WaveCharge 3-Bank delivers simultaneous independent charging at 3 Amps per bank to boats and vehicles running a starting battery, a house battery bank, and a dedicated electronics, trolling motor, or auxiliary battery — each maintained with the correct chemistry profile and charge stage without interference from the others.\u003c\/p\u003e\u003ch3\u003eThree-Bank Charging for Marine and Automotive Applications\u003c\/h3\u003e\u003cp\u003eLarger powerboats, cruising sailboats, overlanding vehicles, and custom builds with dedicated accessory battery systems routinely run three separate 12V battery banks with different usage patterns and charge requirements. The WaveCharge 3-Bank runs three completely independent ISM cycles at full 3 Amps output per bank — three batteries charging at their own rate, in their own stage, with their own chemistry profile, simultaneously.\u003c\/p\u003e\u003ch3\u003eIndependent Banks at Full Output\u003c\/h3\u003e\u003cp\u003eNo bank shares output with another. Each of the three banks runs its own complete 3 Amp ISM circuit independently. A bank recovering a depleted trolling motor or auxiliary battery at full 3 Amps bulk charge does not reduce output available to the bank holding a fully charged starting battery in float maintenance. All three banks operate at full capacity simultaneously.\u003c\/p\u003e\u003ch3\u003eMulti-Chemistry: Lead-Acid and Lithium Per Bank\u003c\/h3\u003e\u003cp\u003eEach bank has its own chemistry selector — lead-acid or Lithium (LiFePO4). A boat or vehicle running a lead-acid starting battery, a lead-acid house bank, and a Lithium auxiliary battery can configure each bank independently for the correct charging profile. Full 3 Amps output at the correct chemistry and maintenance protocol on all three banks simultaneously.\u003c\/p\u003e\u003ch3\u003eISM: 4-Stage Charging on Each of Three 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 restores depleted capacity independently\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.
