MR33 - MR33-STW-20G
With the MR33 steel battery weight for Shortys you can get the balance in your car close to perfection while lowering the center of gravity at the same moment. The weight is only 0.6mm thick and adds a total weight of 20g to your car. It will fit perfectly under every shorty lipo pack and is a great setup option if you use the smaller sized power source in your car.
MR33 offers a steel battery weight for standard 2S packs (MR-STW-28G) as well which will add 28g of weight under the battery in your car.
