The Victron Blue Smart Charger IP22 is one of the smartest battery chargers on the market. Its standout feature is the adaptive charging algorithm with six stages (Test, Bulk, Absorption, Recondition, Float, and Storage), which automatically adjusts to the type of battery usage. This charger achieves an efficiency of up to 94 percent while generating minimal heat. In case of overheating (above 50 degrees Celsius), the output current is automatically reduced to prevent damage. The charging technology of the Victron Blue Smart Charger IP22 impresses with its high level of innovation. It can also charge lithium-ion (LiFePO4) batteries. The well-thought-out algorithm includes a constant current phase, a constant voltage phase, and a maintenance voltage phase. Thanks to the compatible mobile app, wireless monitoring of voltage and current is possible, and settings can be adjusted at any time. The ability to update makes the charger a long-term companion. The Victron Blue Smart Charger IP22 protects batteries from damage. Once the charging process is complete, power consumption drops to less than 0.5 watts to avoid overcharging. An innovative maintenance charge is available when the batteries are not in use, which minimizes gas development to prevent corrosion on the positive plates. Once a week, the voltage is automatically increased to prevent premature battery failure due to electrolyte stratification or sulfation.
