Victron Energy Smart IP43 1+1 Charger, 12V 50A Battery Charger For Lithium and Lead-Acid Batteries, 85-250Vac Power Input

Overview

With two outputs, the Victron Smart IP43 12V 50A 1+1 charger can charge a house bank and a starter battery at the same time. It runs from 85-250Vac and suits lithium and lead-acid batteries on boats, RVs, and backup systems.

Key benefits

• The second output, limited to about 4A at a slightly reduced voltage, maintains a starter battery alongside the main bank.
• Automatic voltage compensation adjusts for cable length and quality so batteries get the proper charge.
• Variable absorption time keeps charging short after shallow discharges and extends it after deep ones.
• Storage mode reduces float voltage during long idle periods to reduce gassing and plate corrosion.

Key features

• 6-stage algorithm: bulk, absorption, recondition, float, storage, and refresh
• Programmable via Bluetooth or VE.Direct, plus a mode button with three preprogrammed algorithms
• BatterySafe mode limits the rate of voltage rise once gassing voltage is reached
• Remote H and Remote L terminals for a remote on-off switch or relay contact
• Programmable relay for alarms or events

Ideal use

Ideal for boats and RVs with a separate starter battery, and for 12V backup banks charged from shore power, the grid, or a generator.

From the manufacturer

Victron Smart IP43 12V 50A Battery Charger The Smart Charger features two outputs, allowing you to charge two battery banks simultaneously. The second output, specifically designed for a starter battery, offers a limited current of approximately 4A and slightly lower voltage. The charger also comes equipped with automatic voltage compensation, which adjusts the output voltage when there is an increase in DC current. This compensation ensures that your batteries receive the proper charge, regardless of cable length or quality. Charge Algorithm With its 6-stage charge algorithm, including bulk, absorption, recondition, float, storage, and refresh modes, this charger can cater to various battery types and optimize the charging process based on battery usage. It also allows programming via Bluetooth or the VE.Direct interface. With the mode button, you can select from three preprogrammed algorithms. Additionally, the Victron Smart Charger incorporates a variable absorption time. When shallow discharges occur, the absorption time is kept short. However, after a deep discharge, the charger automatically extends the absorption time. BatterySafe Mode – Protection Against Excessive Gassing If you select a high charge current and absorption voltage to expedite charging, the charger will automatically limit the rate of voltage increase once the gassing voltage is reached. Storage Mode When your battery remains idle for an extended period, the Storage Mode becomes active. This mode reduces the float voltage to minimize gassing and corrosion of the positive plates. Additionally, the charger periodically raises the voltage back to the absorption level to “equalize” the battery. Remote On-Off and Programmable Relay The Victron Smart Charger has two terminals, Remote H and Remote L, where you can connect a remote on-off switch or relay contact. Alternatively, by pulling terminal H high or terminal L low, you can activate the remote on-off function. The charger’s programmable relay can also be configured through the VE.Direct interface or a Bluetooth-enabled device to trigger alarms or respond to specific events.
