## Description

## NOCO GENIUSPRO25: professional charger 25A (6/12/24V)

The NOCO GENIUSPRO25 is built for workshops that see both cars and 24V vehicles: it charges 6V, 12V and 24V batteries and acts as a clean power supply (12V at 25 A or 24V at 12.5 A) during ECU programming or diagnostics.
For a private owner with one car battery it is overkill; a GENIUS10 covers up to 230 Ah at 12V. If you regularly charge very large banks, the GENIUSPRO50 doubles the current (50 A) and reaches 2000 Ah at 6/12V.
Its 5 A mode looks after batteries of up to 200 Ah with reduced current.

### Features

- •   25 A at 6V and 12V, 12.5 A at 24V; 375 W max.
- •   Up to 1000 Ah at 6/12V and 500 Ah at 24V.
- •   Lead-acid and lithium with BMS (LiFePO4).
- •   12V and 24V power supply mode.
- •   5 A mode for batteries up to 200 Ah or maintenance.
- •   Repair at 6V, 12V and 24V.
- •   Silicone leads flexible to -40 °C; 30 A ANL fuse.
- •   Forced-air cooling, IP20 housing.

### Common questions

Can I use it while programming an ECU?
Yes, its power supply mode holds a steady 12V at 25 A or 24V at 12.5 A.
How long for 100 Ah?
At 6/12V, about 3 h from half charge; 200 Ah takes about 6 h.
Is it fit for outdoor use?
It is IP20 with forced-air cooling, so it belongs indoors, in the workshop.
What comes with it?
Clamps with interchangeable connectors, a 3 m DC cable, a 30 A ANL fuse, 2 screws, an EVA case and the user guide.
