The Blue Smart IP67 Battery Charger is the wireless solution to monitor voltage and current, to change settings and to update the charger when new features become available. With Bluetooth, the functionality of the IP67 charger is enhanced and is similar to that of our IP22 and IP65 chargers. Water, oil or dirt will not damage the Blue Smart IP67 Charger. The casing is made of cast aluminium and the electronics are moulded in resin. Completely encapsulated: waterproof, shockproof and ignition protected. Water, oil or dirt will not damage the Blue Smart IP67 Battery Charger. Setting a new industry standard: 92% efficiency or better, these chargers waste three to four times less heat. And once the battery is fully charged, power consumption reduces to less than a Watt, some five to ten times better than the industry.
