Battery interconnection cable 34mm² 25cm M8 [piece] (2 x 17mm²) 3SPZC21725

Universal connection for AGM and gel batteries

A cable with a cross-section of 2 × 17 mm² and a length of 25 cm has been designed for quick and safe connection of AGM and gel batteries. Thanks to the robust M8 thread, it ensures stable contact even under intensive use – ideal both for installers preparing energy storage systems and for vehicle owners or homeowners with solar systems who wish to increase battery capacity or voltage.

• Parallel connection – doubles capacity while maintaining the same voltage, extending the operating time of battery-powered devices.
• Series connection – doubles voltage while keeping capacity unchanged, enabling, for example, the construction of a 24 V system from two 12 V batteries.
• Mixed (series-parallel) connection – allows simultaneous increase of both capacity and voltage, which is useful in larger off-grid installations.

Construction and installation

The cable features abrasion-resistant and high-temperature insulation, minimizing the risk of mechanical damage during installation in challenging conditions (e.g., in a car trunk or distribution cabinet). The M8 screw enables quick attachment to battery terminals without the need for additional adapters.

• Easy installation – simply match the M8 thread to the standard terminal; no special tools required.
• Safety – a 17 mm² cross-section per conductor ensures low resistance, reducing voltage drops and preventing cable overheating.
• Compatibility – works with most popular AGM and gel battery models available on the European market.

Practical benefits

Installers will appreciate the short length (25 cm), which eliminates unnecessary wiring and helps maintain order in the electrical cabinet. For end users, this means lower energy losses and greater reliability of the entire power system. Additionally, the product is covered by a two-year manufacturer's warranty, ensuring long-term operation without unexpected repair costs.
