Victron Energy Buck-Boost DC-DC Converter 50A
Solve battery charging problems in modern vehicles with the Victron Buck-Boost DC-DC Converter. This 50A converter charges a 12V or 24V service battery from a smart alternator, preventing deep discharge and protecting lithium batteries. It's fully programmable via PC and perfect for camper vans, boats, and vehicles with Euro 5/6 engines. At $94.25 (compare at $292.50), it's a smart investment for reliable auxiliary power.

Fuse and Cable Requirements
For a 50A converter, use a fuse rated at 75A or 80A on the input side (battery to converter) and on the output side (converter to service battery). Use 6 AWG (for lengths up to 3m) or 4 AWG (for longer runs) cables to minimize voltage drop. Always fuse within 18 inches of the battery.
Programming & Setup
Connect the converter to your batteries and then to a PC via USB (cable not included). The VictronConnect or Buck-Boost configuration software allows you to set input/output voltages, charge algorithms, and engine running detection threshold. You can also set it to charge a 24V lithium battery from a 12V alternator.
Comparison with 25A Model
If you have a smaller battery or lower charging demands, consider the 25A model (saves weight and cost). For large service banks (e.g., >300Ah), the 50A is recommended. Both are programmable and offer the same features.
