Batteries & Accessories

Stabilize your electrical system with a complete solution

Voltage, power, and battery type must match each other to keep your system stable.

The sizing of cables and fuses is also important for safe and efficient operation.

This ensures reliable onboard electrical systems – from start to anchorage.

Discover variants, materials, and designs built for marine use. This way, you'll find equipment that remains reliable on board – season after season.

Deine Fragen / Unsere Antworte

Can I use the same battery for starting and powering the onboard electronics?
Technically possible, but not recommended in the long run. Starter batteries cannot withstand frequent deep discharges caused by an autopilot or a cooler. If you continuously operate supply consumers, you should plan for a separate battery bank system.
What is the difference between AGM and normal wet-cell batteries on board?
AGM batteries are sealed, can be installed in any position, and are less sensitive to vibrations – these are clear advantages on board. Wet-cell batteries are cheaper to buy, but require ventilation and occasional checks of the electrolyte level.
Why must marine cables have tinned copper?
Salt air and humidity quickly corrode normal copper, which increases contact resistance and, in the worst case, leads to heat generation. Tinned copper is significantly more corrosion-resistant and is explicitly intended for use on board.
How do I properly charge a LiFePO4 onboard battery?
LiFePO4 batteries require a charger that explicitly supports this battery type and uses the appropriate charging profile. Conventional lead-acid chargers can damage LiFePO4 batteries or not fully charge them – the charger should be checked for compatibility before purchase.
