At 396Wh and just 1.85kg, it gives you around 20% more capacity than the original MAX Sport Battery while retaining the shorter, lighter Sport format.\u003c\/p\u003e\n\u003cp\u003eFor surf foiling, downwinding, parawinging and wing foiling, that is a useful combination. There is less battery mass hanging from the board than with the full-size MAX High Power battery, helping the setup feel easier to pump, redirect and unweight, while still giving you a meaningful increase in usable runtime over the original Sport battery.\u003c\/p\u003e\n\u003ch2\u003eWho does it suit?\u003c\/h2\u003e\n\u003cp\u003eWe would particularly look at the 396 for experienced riders using Foil Drive as an \u003cem\u003eassist\u003c\/em\u003e rather than as a conventional eFoil. It makes a lot of sense for surf foil sessions, downwind runs, wing foiling and parawinging where you predominantly need the motor for take-off, recovery or linking sections.\u003c\/p\u003e\n\u003cp\u003eIt is also a very good choice for lighter riders and anyone who has found the larger MAX batteries add more swing weight than they would like. If your priority is making an Assist MAX installation feel lively and relatively unobtrusive, this is arguably the sweet spot in the range.\u003c\/p\u003e\n\u003cp\u003eIf you rely heavily on continuous motor power or simply want the longest possible sessions, choose the larger \u003ca href=\"https:\/\/www.thesupco.com\/products\/foil-drive-max-high-power-battery\"\u003eFoil Drive MAX High Power 594Wh Battery\u003c\/a\u003e instead.
