NOCO GX4820: industrial charger 20A (48V)
The NOCO GX4820 is the 48V member of the GX series. It is meant for electric vehicles with a 48V pack, such as golf carts, pallet trucks or utility vehicles, with batteries from 55 to 425 Ah.
With the same 960 W as the GX2440 and GX3626, the current drops to 20 A because the voltage is higher. If your vehicle is 24V or 36V, this is not your charger: pick the model whose voltage matches.
It offers NORM (57.6 V), COLD/AGM (58.8 V), AGM+ (62.4 V) and LI-ION (58.4 V) modes, Repair at 64 V and a 54.4 V / 10 A power supply.
