Modster Power Packs - finally, there are Lipos that have been custom-made for our Modster models. Our main focus is on the configuration with the connector systems used in our own brand and the precise fit of the battery in the respective model. However, the Modster Power Packs are also a great choice when used with other model brands! This honest 35C battery line comes from one of the largest producers of lithium-polymer batteries worldwide. Extensive quality assurance processes during production and before delivery ensure consistently high quality.
