Convert your M6 female or M6 male battery terminals to SAE top posts terminals. SAE top post terminals are commonly used on automotive batteries, but many lightweight racing batteries come with M6 female or M6 male terminals.
Not only do these terminals look great, but aluminum is extremely lightweight (70% lighter than brass, 45% lighter than titanium). Machined of aluminum and with a mil-spec coating, VPH SAE Adapters save over 2 ounces a set. Brass M6 to SAE terminal adapters weigh around 100 grams a set or more. These adapters weigh only 16 grams a set. Aluminum also has twice the electrical conductivity of brass. These are the perfect complement to your lightweight battery. For the weight saved per amount spent, this is more cost effective than titanium bolts! Don't put heavy SAE terminals on your lightweight battery.
