NOCO GEN5X3: on-board charger 3 banks 15A (12V)

If your boat carries three 12V batteries (starting, house and, for example, a trolling motor), the NOCO GEN5X3 looks after all of them at once through three isolated 5 A banks. Each battery can be up to 120 Ah.

With two batteries, the GEN5X2 is enough. If any battery exceeds 120 Ah, or the boat is used daily and you need faster recharges, the GENPRO10X3 delivers 10 A per bank and accepts up to 230 Ah.

The unit measures 180 x 145 x 56 mm and mounts in any orientation with anti-vibration backing.

Common questions

Can I connect just two batteries?

The banks are independent, but if you will only ever use two, the GEN5X2 is more compact.

Which battery voltage does it accept?

12V only, lead-acid or lithium with BMS.

How long for a 100 Ah battery?

About 15 h from half charge, on each bank.
