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 aluminum die-cast, and the electronic components are encapsulated in resin. The highest efficiency. Although they are 92% 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. Variable charging algorithm, 5-stage initial charge - absorption - reconditioning - float - storage. The Blue Smart charger features battery management with microprocessor-controlled batteries. Its "A DA PT A you VA" function automatically optimizes the charging process based on battery usage. The storage mode is activated when the battery has not experienced any discharge 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. It also charges Li-Ion batteries (LiFePO4). The Li batteries are charged using a simple start algorithm - absorption - float. Overheating protection: the output current is reduced when the temperature rises to 60 °C, but the charger will not fail.
