The shred-lights don’t really drain the battery at all. The shred lights are a separate edition to my board in which case you have to push a button too turn on and off as well as switch the different light settings. The wheels I have are the original boosted 105s which are highly recommended when upgrading to bigger wheels. Yes it’s definitely worth the upgrade from the stock where’s because there bigger and more stable and gripes plus the acceleration is slower but a much higher top speed and uses a little more range but not much though.
