Can confirm it does (battery stays at 100% as long as you are going straight and not turning in circles). I ignored these in favor of the ultraglide fins because it used not not work with seaglide (would keep it running on fumes) and i didnt really need to charge my tools due to the existence of battery chargers, but it is worth it for the infinite seaglide (kinda makes ion batteries pointless tho)
