12.8V modular battery power cable
This set is made for 12.8V class batteries. The 5.5 mm cable diameter is noticeably thinner than the 10.5 mm 48V class sets; the difference reflects current capacity and installation space.
The wire diameter of the tinned copper conductor is 0.08 mm; the cable is double-insulated, halogen-free and flame-retardant. The black and red colours prevent mixing up positive and negative. In boats, caravans or small 12V systems, Solar Nexo calculates the current before installation to ensure the correct cross-section is used.
Choosing the wrong set for battery cables can affect device warranty and safety. Check the series name, voltage and cable type (power or communication) before ordering; if in doubt, the Solar Nexo technical team will verify the product match.
