Overview
Independent Charging for Three Battery Banks
The GEN5X3 supplies 5 amps of charging current to each of its three battery banks, allowing every battery to be charged and maintained independently. Selectable charging modes support flooded, gel, maintenance-free, AGM, EFB, CA, and lithium batteries used in marine, starter, and deep-cycle applications.
- 15-amp total output with three independent 5A charging banks.
- Compatible with lead-acid and lithium battery chemistries.
- Supports batteries up to 120Ah with maintenance charging for all battery sizes.
Compact & Durable
More Power in Less Space
The GEN5X3 is 37% smaller while delivering over 43% more power than the previous GENM3 charger. High-frequency switch-mode technology and an onboard microcomputer maximize charging efficiency while maintaining a compact footprint for permanent onboard installation.
- IP68-rated waterproof construction.
- Integrated anti-vibration mounting system.
- Built to withstand harsh marine environments.
Feature Highlights
Advanced Smart Charging
Selectable Charge Modes
Independently select 12V, 12V AGM, 12V Lithium, or 12V Repair charging modes for each battery bank.
