This is an optional Team Associated LiPo Battery Brass Weight Plate Set, including one 26g and one 43g brass plate. These B6 battery weights fit perfectly under your shorty LiPo batteries so that you can add weight while reducing your vehicle's center of gravity.
Each plate measures 3.74" in length and 2.08" in width, but the 26g plate is 0.02" thick, while the 43g plate is 0.04" thick. Each plate is etched with its weight for easy identification. Part# 91744
