GEN5X3 by NOCO: 3-bank marine charger 12V 15A, sealed IP68
Three isolated 5 A outputs in a single on-board charger: the GEN5X3 looks after three 12 V batteries, lead-acid or BMS lithium, with no swapping of clamps.
3 banks of 5 A, 15 A in total | Each bank up to 120 Ah | Lead-acid or 12 V BMS lithium | IP68, -20 °C to +40 °C
GEN5X3 by NOCO: 3-bank marine charger 12V 15A, sealed IP68
Can one charger really handle three different batteries? With the GEN5X3, yes: it splits 15 A across 3 isolated 5 A banks that run independently, each serving a 12 V battery of up to 120 Ah.
How long does it take? As a manufacturer reference, a 100 Ah battery at 50 % discharge recovers in about 15 h per bank. Every output accepts lead-acid or 12 V lithium with a BMS, offers a repair mode for sulphated batteries and a force mode for those below 1 V.
It is sealed to IP68 and bolts down in any orientation on its anti-vibration backing; 2 self-tapping screws come in the box.
Before you order, check
- › The number of batteries: 3 banks; with only 2, the GEN5X2 is enough.
- › Each battery is 12 V and no larger than 120 Ah; for banks up to 230 Ah there is the GENPRO10X3 (3 × 10 A).
- › Their chemistry: lead-acid or 12 V lithium with BMS.
- › You have room for 180 × 145 × 56 mm near a 100-240 VAC supply.
- › Still have a question? Call us and we will confirm whether this is your model.
