TBH, the HP max with much lighter batteries is my choice. At least until the smaller battery is available on the Max+.
MAX+ is definitely more refined, quieter and more power, but the MAX HP was and remains brilliant.

The new Foil Drive Assist MAX+ is a serious upgrade. Right from the first drop, you can feel noticeably more power compared to the standard Assist MAX, with everything running super smooth in the water. The new battery is a massive improvement, and being able to track exact battery percentages adds complete peace of mind during setup. Paired with the FM+ 650, the performance is phenomenal. Having everything ready right out of the box including the Mini Pod and Split Bolts makes the initial assembly seamless and elevates the entire ride experience.

Loving the extra power and runtime, sooooo good.

It is a real improvement compared to the standard high-power battery. Before buying, I was not sure because of the extra weight of the Max+, but you don't feel it and it feels more balanced on the water. The extra battery life is definitely there. Storage and charging are straightforward with the 43V charger. It's a costly investment, but it really changes the experience and the feeling on the water.
