Recommended for you

In the Battery Accessories product group, you will find the accessories needed for mounting and charging batteries: a battery mounting kit, a Pro Supply battery mount with strap, a mounting strap for batteries and tanks, and Victron Energy's DC-DC converter 9A/12V and Direct cables in 3 and 10 meter lengths.

Proper battery securing is a safety issue, not just a convenience one: a loose battery can move and cause a short circuit or even a fire hazard in rough seas or sudden turns — a securing kit or strap mount will ensure that the battery stays in place in all conditions. The strap can also be used to securely secure other heavy objects, such as fuel tanks.

The Victron Energy DC-DC converter is a key component in dual battery systems: it safely charges an auxiliary battery (e.g. a household battery) from the main engine charger between different voltage levels and battery types, preventing overcharging or undercharging. This is especially important if your boat has a lithium battery and a lead acid battery in the same system, as their charging profiles differ significantly.

Direct cables provide a reliable and safe connection between the converter and the batteries — choose the cable length according to the installation distance, and avoid excessively long, extra cable runs that increase voltage drop and can cause unnecessary heating at high currents.

Check the tightness of the attachment regularly during the season, as vibration can loosen straps and bands over time — a loose battery is a safety risk in a sharp turn or in waves. When installing a Victron inverter, it is advisable to carefully follow the manufacturer's instructions for battery type-specific settings to ensure optimal charging and avoid damaging the battery.

Also consider the effect of temperature on battery mounting and charging — battery capacity decreases in cold weather, so especially for winter use or in cold water, the mounting and wiring must be particularly reliable to withstand thermal expansion and contraction.

Also consider the overall cleanliness and ventilation of the battery compartment when planning your mount — a well-ventilated, clean battery compartment reduces the risk of corrosion and makes it much easier to check the battery's condition during the season.

Compare different mounting methods based on the size and weight of your battery — a heavier battery will require a more sturdy mount than a lighter lithium battery in the same space.

Check the battery cable connections regularly for oxidation, as poor contact impairs charging and power supply.

Ask for advice on choosing the right mounting method if the size or shape of your battery differs from the usual standard model.

Note the installation date of the fasteners so you know when the next inspection should be done during the season.
