Mastervolt 12v 25a Chargemaster Battery Charger

Product Description

The Mastervolt ChargeMaster battery charger is designed to help batteries perform better and last longer, providing fast and complete charging wherever you are. The internal metal to metal connections are all equipped with strain relief to prevent damage from corrosion or overheating, ensuring long life and less chance of failure. Even without the batteries connected, the ChargeMaster can provide a reliable DC output to power lights or keep the fridge cold!

The 3-STEP+ charging memory ensures more power and a longer life for your batteries, and will even charge depleted batteries. The ChargeMaster is suitable for all types of battery, and also has a wide input voltage range, which ensures perfect automatic operation anywhere in the world. It also has a built in memory function, so batteries will not get overcharged even if the mains supply is unreliable. It is also MasterBus compatible, meaning they can be connected easily to a MasterBus system where you can operate and monitor all Mastervolt devices in one panel.General specifications:
