## Description

## NOCO GENIUSPRO50: professional charger 50A (6/12/24V)

The NOCO GENIUSPRO50 is for anyone charging big batteries and banks every day: trucks, plant, fleets or boats with hundreds of Ah. At 50 A it restores 200 Ah from half charge in about 3 h, and 1000 Ah in about 15 h.
If your batteries rarely exceed 500 Ah, the GENIUSPRO25 (25 A, up to 1000 Ah at 6/12V) is smaller and weighs 1.22 kg against 2.27 kg. Both cover 6V, 12V and 24V and offer a 12V and 24V power supply.
For more modest batteries, the 10 A mode lowers the current for batteries up to 400 Ah.

### Features

- •   750 W behind 50 A at 6/12V and 25 A at 24V.
- •   Up to 2000 Ah at 6/12V and 1000 Ah at 24V.
- •   Takes lead-acid and lithium with BMS (LiFePO4).
