  • Our batteries are splashwater proof according to the IP54 standard. They cannot be fully immersed in water or handle heavy rains. To avoid problems use a waterproof battery container and position the battery upright on a slightly elevated level so that it is not continously standing in the water, or water can enter via the top of the battery.
  • Extra (ballast) weight might be required when using with bait boats. Please consult your bait boat specialist for specific advice. 
  • If you use a battery carrying case please ensure that NO water (from rain for instance) remains in the battery bag as this can damage the battery. Waterdamage is explicitly excluded from our warranty terms.
