<p>Modification for the Hosim Q903/Q905 RC car that allows you to use 2s (7.4V) 18650 Li-ion battery packs. Ideal for users who want to upgrade from stock batteries for increased capacity and flexibility. This mod securely holds standard 18650 cells and fits the chassis with minimal changes. Great for longer run times and easy battery swaps. The hold downs for the elastic just need a quick cut with hobby knife. Use couple small self tapping screws to hold the base to the holder.</p>
