Do you know your local boating laws?

Most states have laws stating that it is unlawful to operate a motorized vessel equipped with a storage battery unless the battery is secured against shifting. The battery must be equipped with non-conductive terminal protectors / covers to prevent accidental shorting. Both positive and negative terminals must be covered. A covered battery box with strap is best. The NOCO HM300BKS Group Size 24 Battery Box keep your boat legal on the water!
