The Battery Tender® WaveCharge Pro 2-Bank delivers 10 Amps per bank — more than three times the output of the WaveCharge line — with UL marine ignition protection, the highest waterproof rating in the WaveCharge family, and the same independent per-bank ISM (Infinite Sequential Monitoring™) architecture that makes WaveCharge the standard for marine multi-bank charging.\u003c\/p\u003e\u003ch3\u003e10 Amps Per Bank — For Larger Batteries and Faster Recovery\u003c\/h3\u003e\u003cp\u003eAt 10 Amps per bank, the WaveCharge Pro 2-Bank recovers large marine house batteries significantly faster. A depleted 150Ah house battery that takes over 50 hours to recover at 3 Amps recovers in approximately 15 hours at 10 Amps — with ISM managing the taper from bulk charge to absorption to float maintenance automatically. For boats with large AGM or Lithium house battery banks, or for commercial boats that need batteries ready on a schedule, Pro output is the practical threshold.\u003c\/p\u003e\u003ch3\u003eUL Marine Ignition Protection\u003c\/h3\u003e\u003cp\u003eCertified to not produce ignition-capable sparks during normal operation or connection in the presence of fuel vapors — the independent certification required for charging equipment installed in enclosed marine spaces near fuel systems. The WaveCharge Pro 2-Bank is certified for installation in engine rooms, fuel-adjacent compartments, and any enclosed marine space where ignition-protected equipment is required.\u003c\/p\u003e\u003ch3\u003eIndependent Banks at Full 10 Amps Output\u003c\/h3\u003e\u003cp\u003eEach bank operates as a complete independent 10 Amp charging circuit. Bank 1 can be in bulk charge recovering a depleted house battery at full 10 Amps while Bank 2 is in float maintenance on a fully charged starting battery — simultaneously, with no output reduction on either bank.\u003c\/p\u003e\u003ch3\u003eMulti-Chemistry: Lead-Acid and Lithium Per Bank\u003c\/h3\u003e\u003cp\u003eEach bank has its own chemistry selector for lead-acid or Lithium (LiFePO4) batteries, delivering the correct ISM charging profile at full 10 Amps output.
