Bluetooth Smart enabled The Blue Smart IP67 charger is the wireless solution for monitoring voltage and current, changing settings and updating the charger when new features are released. Thanks to Bluetooth, the functionality of the IP67 charger is enhanced and is similar to our IP22 and IP65 chargers. Fully encapsulated: waterproof, shockproof and fireproof Water, oil and dirt will not harm the Blue Smart IP67 charger. Its casing is made of cast aluminum and the electronic components are cast in resin. The highest efficiency ever achieved! We set a new industry standard: Although they are 92% efficient or higher, these chargers generate three to four times less heat. And once the battery is fully charged consumption drops to less than one watt, five to ten times less than the industry norm. 5-Stage Variable Charge Algorithm: Initial Charge - Absorption - Reconditioning - Float - Storage The Blue Smart charger features microprocessor controlled "adaptive" battery management. Its "adaptive" function will automatically optimize the charging process based on the use that is given to the battery. Storage mode: Less aging and maintenance when the battery is not in use Storage mode is activated when the battery has not been discharged in 24 hours. In storage mode, the float voltage is reduced to 2.2V/cell (13.2V for 12V batteries) to reduce gassing and corrosion of the positive plates. Once a week, the voltage is raised back to the absorption level to “even out” the battery. This feature prevents electrolyte stratification and sulfation, the main causes of battery failure. Also charges Li-Ion batteries Li-ion batteries are charged with a simple initial charge – absorption – float algorithm. Fully discharged battery recovery function Will start charging even if the battery has been discharged to zero volts. It will reconnect to a fully discharged lithium ion battery with the internal disconnect feature.
