Safe to leave on, and on, and on...

Whether you're storing an RV or motorcycle through winter or a boat during the off-season, the Blue Smart Charger keeps batteries healthy for months of inactivity. The storage mode adjusts charge levels when the battery reaches 100%, rather than applying a constant voltage like trickle chargers. This keeps batteries far healthier over time.

Connect, plug in, and sit back

Why think about the charging process when your charger can do it for you? The Blue Smart Charger maximises battery life by using an advanced algorithm. It charges fast to 80%, then slows for the final 20%, based on a chemistry-specific or custom profile. In normal mode, it works for 99% of batteries and can even revive fully discharged ones from 0 volts.

The best care for any battery

Give every chemistry the treatment it needs, using only one charger. Choose from 8 pre-programmed charge profiles for lithium, lead-acid, AGM, gel, or flooded batteries, or create a custom one for fine-tuning. Low power mode makes the Blue Smart Charger compatible with smaller battery sizes.

Configure in just a few taps

The free VictronConnect app for Android or iOS lets you adjust charging profiles, track real-time status, and view usage history, so you can stay in charge without touching the charger.

Everything a charger
should have

Lithium battery mode

As lithium batteries require special care, the Blue Smart Charger comes with a dedicated Li-ion setting. It adjusts the algorithm to charge the battery faster, working within lithium's tight voltage tolerances and preventing overcharge damage. It can even revive deeply discharged batteries with automatic under-voltage protection reset.

Reconditioning mode

Lead-acid batteries left partially charged or sitting idle for weeks can lose capacity due to sulfation buildup. The recondition mode can help restore performance by applying a higher-voltage charge cycle that breaks down these capacity-robbing deposits.

Power supply mode

Need a stable power source for your equipment? The Blue Smart Charger doubles as a DC power supply. Select this mode in the VictronConnect app to deliver constant voltage to your devices—with or without a battery connected.

Dead battery detection and revival

The Blue Smart Charger automatically adapts to all battery conditions, using a highly-advanced charging algorithm. If it detects a fully discharged battery during the test stage, it immediately applies a low current to revive it, even from 0 volts.

Temperature-compensated charging

Before starting the charging process, the algorithm measures the ambient temperature and compensates for it. The temperature is measured again at low current, for instance when the battery is nearly full or when the charger is in storage mode. This allows the Blue Smart Charger to perform from -20ºC/-4°F to +50ºC/122°F without special settings.

SafetyShield+ protection: the professional standard

Designed for reliability in all conditions, the Blue Smart Charger features IP65 water, dust, and chemical resistance, plus comprehensive safeguards against overtemperature, short-circuit, and reverse polarity.
