Victron Blue Smart IP22 12V 20A Charger: professional-grade efficiency for 12-volt systems
The Victron Blue Smart IP22 12V 20A is a high-performance smart charger designed for fast, safe and optimized charging of 12-volt batteries, including AGM, Gel, flooded lead-acid and LiFePO₄ lithium. Thanks to its advanced multi-stage charging algorithm, Bluetooth connectivity and high energy efficiency, it is widely used in marine applications, motorhomes, vehicles, industrial machinery and small off-grid systems.
Its intelligent electronics ensure a perfectly controlled charging cycle while reducing stress on the battery. The Blue Smart IP22 12V 20A is suitable for medium-sized battery banks and delivers stable charging performance even in demanding environments. For users who require precise battery care and long-term reliability, it stands as one of the best professional options available.
Bluetooth Smart connectivity and full control with VictronConnect
This charger includes Bluetooth Smart, enabling complete remote monitoring through the VictronConnect app. Users can view real-time voltage, current, charge stages, history, graphs and status information directly from a phone or tablet.
- Real-time voltage
- Charging current
- Active charging stage
- Complete charging history
- Statistics and graphs
- Selectable profiles for AGM, Gel, Flooded and LiFePO₄
This level of monitoring is crucial in marine systems, motorhomes, service vehicles, workshops and industrial equipment where battery reliability is essential.
Adaptive multi-stage charging algorithm
The Blue Smart IP22 12V 20A uses an advanced multi-stage algorithm including bulk, adaptive absorption, float, storage, periodic absorption and recondition mode. Each stage is optimized to maximize battery lifespan and ensure full and balanced charging.
During bulk charging, the charger delivers the full 20A output until absorption voltage is reached. The adaptive absorption phase adjusts its duration according to the actual depth of discharge, preventing unnecessary exposure to high voltage. Float mode maintains the battery fully charged with minimal stress, while storage mode reduces voltage when the battery remains connected for long periods.
Every seven days the charger applies a brief automatic absorption cycle to counteract self-discharge. The recondition mode is available for lead-acid batteries that need recovery after deep discharge or sulfation.
Full compatibility with all major battery technologies
The charger includes profiles for all common chemistries:
- AGM
- Gel
- Flooded lead-acid
- LiFePO₄ lithium
The lithium profile removes unnecessary stages and optimizes voltage specifically for LiFePO₄ cells. The charger can also reactivate lithium batteries reading 0 V due to BMS protection.
Selectable charging modes
- Normal: AGM/Gel
- Normal + Recondition: flooded batteries
- High: higher-voltage flooded batteries
- High + Recondition
- Li-ion: LiFePO₄
Temperature compensation
Charging voltage automatically adjusts according to ambient temperature. This protects lead-acid batteries and ensures full charge in cold climates. Compensation is disabled when using the lithium profile.
Special operating modes
- Low-current mode: limits output to 50% and disables the fan
- Night mode: silent operation for eight hours
- Power-supply mode: provides stable DC power without a battery
Deep-discharge recovery
The charger can recover deeply discharged lead-acid batteries by applying a low current until voltage rises to a safe level. This is essential in marine systems, seasonal machinery and vehicles left unused for long periods.
VE.Smart Networking
The Blue Smart IP22 12V 20A can wirelessly communicate with other Victron devices to synchronize charging and compensate voltage drops. It works with SmartShunt, BMV monitors and Smart Battery Sense for:
