The most capable charger in the WaveCharge family. The Battery Tender® WaveCharge Pro 4-Bank delivers 10 Amps per bank across four completely independent charging circuits — 40 Amps total on-board charging capacity — with UL marine ignition protection, full Multi-Chemistry support for lead-acid and Lithium, and ISM (Infinite Sequential Monitoring™) managing each bank's complete 4-stage charge cycle independently and simultaneously.
Four Banks. 10 Amps Each. 40 Amps Total.
Each of the four banks is a complete independent 10 Amp charging circuit running its own ISM algorithm at its own charge stage with its own chemistry setting. No output sharing. No inter-bank interference. Bank 1 can be recovering a deeply depleted Lithium house bank at full 10 Amps bulk charge while Banks 2, 3, and 4 are simultaneously in float maintenance on fully charged lead-acid service batteries — four different charge stages, four different batteries, one unit.
UL Marine Ignition Protection
Certified to not produce ignition-capable sparks during operation or connection in the presence of fuel vapors — the certification required for charging devices in enclosed marine spaces near fuel systems. The WaveCharge Pro 4-Bank is rated for installation in engine rooms, fuel-adjacent compartments, and any enclosed marine location where ignition-protected equipment is mandatory.
Multi-Chemistry: Lead-Acid and Lithium Per Bank
Each of the four banks has its own chemistry selector. A boat running any combination of lead-acid and Lithium banks across four circuits configures each bank independently — the correct ISM profile at full 10 Amps output for each chemistry on each bank, all running simultaneously.
ISM: 4-Stage Charging on All Four Banks 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 at the correct chemistry setting
-
Absorption — Current tapers per bank as each battery approaches full charge, preventing overcharge for lead-acid and Lithium alike
-
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.
One Unit. Complete Coverage.
Four individual 10 Amp chargers maintain four batteries with equivalent per-battery results — but require four separate units, four installation locations, and four power connections. The WaveCharge Pro 4-Bank delivers the same independent per-bank ISM performance from a single on-board installation, a single AC connection, and four dedicated output circuits.
Applications
- Large offshore and bluewater cruising boats with four-bank electrical systems
- Commercial and charter boats requiring rapid multi-bank recovery between trips
- Boats with dedicated starting, house, bow thruster, and trolling or anchor winch batteries
- Liveaboard boats with high-capacity mixed lead-acid and Lithium battery systems
- Any four-bank 12V marine application requiring UL marine ignition protection and maximum output
Automatic Temperature Compensation
All four banks adjust charge voltage automatically based on ambient temperature for lead-acid applications — ensuring correct charging across all four banks in any operating or storage environment.
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 — incorrect connection on one bank does not affect the remaining three
- Short-circuit protection per bank
- IP67+ sealed housing
