WaveCharge Pro 2-Bank 12V 20 Amp Battery Charger and Maintainer

$254.95

Description

The WaveCharge Pro line exists for boats where 3 Amps per bank is not enough. 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.

10 Amps Per Bank — For Larger Batteries and Faster Recovery

At 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.

UL Marine Ignition Protection

Certified 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.

Independent Banks at Full 10 Amps Output

Each 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.

Multi-Chemistry: Lead-Acid and Lithium Per Bank

Each bank has its own chemistry selector for lead-acid or Lithium (LiFePO4) batteries, delivering the correct ISM charging profile at full 10 Amps output. Boats transitioning house banks from lead-acid to Lithium can configure each bank independently during the transition.

ISM: 4-Stage Charging on Each Bank at 10 Amps

  • Initialization — Individual battery health check before current flows on each bank
  • Bulk Charge — Full 10 Amps output per bank restores depleted capacity rapidly
  • Absorption — Current tapers per bank as each battery approaches full charge, preventing overcharge damage for lead-acid and Lithium
  • Float Maintenance — Correct protocol for the selected chemistry on each bank, 24/7, indefinitely

Compatible per bank: 20Ah to 200Ah at 12V. Lead-acid: flooded, AGM, gel cell, sealed MF. Lithium: LiFePO4.

Applications

  • Boats with large starting and house battery banks requiring faster recovery
  • Powerboats and sailboats with high-capacity AGM or Lithium house batteries
  • Commercial and charter boats requiring rapid battery turnaround
  • Boats requiring UL marine ignition protection in engine room installation
  • Any two-bank 12V marine application where 3 Amps per bank is insufficient

Automatic Temperature Compensation

Both banks adjust charge voltage automatically based on ambient temperature for lead-acid applications — ensuring complete charging in cold conditions and preventing overcharge in heat.

Safety Features

  • UL marine ignition protection — certified for enclosed marine spaces and fuel vapor environments
  • Spark-proof connection on each bank
  • Reverse polarity protection per bank
  • Short-circuit protection per bank
  • IP67+ sealed housing
