Suggestion about qualisports dual-battery dolphin?

[Dowen]

Hey, y’all, Newbie here. I see the new dolphin from FOLDING WHEELS, and I really consider the dual-battery dolphin. Is there any advice about this brand cause I exactly see the Black Friday sale on their website? I'd like to learn about the fat tire if any owner can provide their reviews on their Belugas? Thanks in advance!

Those batteries are cool on one hand but may be custom builds in the future for replacement. I’m a fan of commonly used battery cases.
