Bluetooth Smart activated. The Blue Smart IP67 charger is the wireless solution for monitoring voltage and current, changing settings, and updating the charger when new features become available. Completely encapsulated, waterproof, shockproof, and fireproof. No water, oil, or dirt can damage the Blue Smart IP67 charger. The housing is made of die-cast aluminum, and the electronic components are encapsulated in resin, ensuring the highest efficiency. We are setting a new standard in the industry. Although the efficiency is 92 percent or higher, these chargers generate three to four times less heat. Once the battery is fully charged, power consumption is reduced to less than one watt. This is five to ten times less than the industry standard. The Blue Smart charger features battery management with microprocessor-controlled batteries. The storage mode is activated when the battery has not discharged within 24 hours. Once a week, the voltage increases to the absorption level to balance the battery. This function prevents electrolyte stratification and sulfation, which are the main causes of battery failure. Li-ion batteries (LiFePO4) are also supported. The Li batteries are charged with a simple start algorithm that provides overheating protection. The output current is reduced when the temperature rises to 60 °C, but the charger remains operational.
