Description
GEN5X3 15-Amp 3-Bank On-Board Battery Charger, Maintainer & Battery Desulfator
The NOCO GEN5X3 is a fully automatic three-bank onboard battery charger engineered for marine, recreational, and utility applications. Delivering 15 amps of total charging power (5 amps per bank), it independently charges and maintains three 12-volt batteries while supporting both lead-acid and lithium chemistries. Intelligent charging, automatic battery maintenance, repair functionality, and rugged IP68 waterproof construction make it ideal for permanent onboard installation.
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.
