DESCRIPTION
Intelligent Adaptive Charging for Marine and Off-Grid Systems
The Victron 12V 50A Phoenix Smart IP43 12/50(1+1) Battery Charger offers professional-level battery maintenance for demanding marine, automotive, and off-grid applications. Designed to handle the rigours of mobile power systems, this intelligent Victron smart charger ensures your batteries receive the precise energy they need to maximise lifespan and performance. With a robust 12V architecture and 50A output, it is an essential component for any reliable standalone power system.
Complete Control with Bluetooth Smart
Built-in Bluetooth connectivity transforms how you interact with your power system. Using the free VictronConnect app on your smartphone or tablet, you can monitor charge status, adjust settings, and update firmware completely wirelessly. For larger, integrated setups, the VE.Direct port provides seamless wired communication with Victron GX devices, enabling comprehensive system oversight.
Adaptive 5-Stage Battery Management
Standard chargers can easily overcharge batteries during extended periods of shore power or standby use. This unit employs a highly advanced, adaptive 5-stage algorithm: bulk, absorption, recondition, float, and storage. By automatically adjusting the charging process based on how the battery is being used, it delivers the exact right amount of charge.
If the battery experiences only shallow discharges, the absorption time is reduced to prevent overcharging. Conversely, after deep discharges, the system automatically extends the absorption phase to ensure a complete recharge.
Superior Battery Protection
Prolonged periods of inactivity often lead to early battery failure due to sulphation and corrosion. The innovative Storage Mode activates automatically after 24 hours without discharge. It reduces the float voltage to minimise gassing and positive plate corrosion, while initiating a weekly refresh cycle to prevent electrolyte stratification. Furthermore, the BatterySafe mode prevents damage from excessive gassing by automatically limiting the rate of voltage increase during rapid charging.
This dual-output model features a high-current primary connection for your main house battery bank, accompanied by a dedicated 4A trickle charge output that is ideal for maintaining an engine starter battery.
Built for Harsh Australian Environments
Operating in marine vessels or off-grid caravans means exposing equipment to challenging conditions. The IP43 protection rating ensures the internal electronic components are shielded against dust and water spray up to 60 degrees from vertical, provided the unit is mounted correctly. The natural convection cooling system utilises a large aluminium heatsink, eliminating the need for noisy cooling fans while maintaining exceptional efficiency and thermal stability even in warmer climates. Additionally, automatic voltage compensation offsets DC cable voltage drop by slightly increasing output voltage when DC current increases, ensuring optimal delivery to your battery bank.
Versatile Chemistry Support
Whether you are using traditional lead-acid, AGM, Gel, or advanced Lithium-ion (LiFePO4) battery banks, this charger adapts to your specific chemistry. It features a fully programmable charge algorithm and a dedicated lithium mode. Charger remote on/off control can even be managed directly by a Lithium-ion Battery Management System (BMS) via the integrated two-pole terminal.

Victron Energy Limited Warranty Policy
Direct Customers
Victron Energy provides the following warranty to any direct customer (OEM, distributor or dealer) in relation to any products that Victron Energy has directly sold to the direct customer. This warranty is not an end-user warranty between Victron Energy and an end-user, and end-users shall not have any rights or remedies under this limited warranty towards Victron Energy directly. The direct customer shall, in turn, ensure that the end-user is provided with a warranty identical to this warranty, subject to applicable local mandatory law.
End-Users
Victron Energy may also provide a warranty directly to end-users, in which case the below warranty conditions equally apply to such warranty. In that case, end-users shall claim their warranty at their place of purchase or through the original direct customer of Victron, which can be found through the support section on Victron’s website https://www.victronenergy.com/support. Hence, the direct customer shall on behalf of Victron Energy deal with any warranty claims made under any warranty that Victron Energy may provide directly to end-users. This support section on Victron’s website https://www.victronenergy.com/support will provide further guidance on the procedure for end-users to make a claim under this limited warranty.
If the end-user is a consumer – a natural person who is acting for purposes which are outside that person's trade, business, craft or profession – the following applies.
