German company LRP have introduced a range of new under battery brass weights. Available for Shorty and standard size batteries, the weights are made from high-quality brass with the XTEC logo, the dimension and weight engraved on a matte black finish to finish off the look. The weight is a chassis tuning option that mounts under the battery to improve the overall balance and reduce the center of gravity. Thanks to the flat profile, it is easily installed under a battery, and is a great tuning option for a variety of applications. The weights come in 10g, 30g, 39g and 65g for Shorty battery and 28g, 44g and 59g for standard batteries in set of 2.
