The ProTournament 300L Charger/Maintainer by ProMariner is an intelligent 3 bank 30 amp battery charger designed for tournament use. One of the key features of this charger is that the ProTournament 300L is capable of sensing increased demand from the auxiliary battery and diverting up to the 100% of the availible power to that battery. This incredible charger from ProMariner is also fully temperature controlled and microprocessor controlled so it will not overcharge your batteries. The ProTournament 300L is an extremely durable and rugged charger that is also completely waterproof. 

The ProTournament 300L is specifically designed with professional tournament use in mind. It is lightweight at only 11 pounds, yet it is still able to offer an incredible 30 amps of charge and will bring your batteries up to 100% even on long extension cords that drop the input voltage down to as low as 90 VAC. Charging will automatically distribute its full rated output of 30 amps to any one bank or combination of all battery banks. The ProTournament 300L distributes and uses every charging amp with no waste. This "L" version, Long, has cable outputs of 12 feet, 9 feet, and 9 feet for the most demanding distance requirements.
