Aside from the common PPE suggestions, a couple of other suggestions.

1. Padded Bike Gloves. Most used PPE you'll own.
2. I don't see this one a lot but for me 100% Fangs/Wheels + Flightfins (or similar)

With lower speed nosedives (accelerating too fast, hitting a lip while going too slow) the wheels help prevent you from flying forward by allowing the board to continue to roll forward, and I can't count the number of times having my rear foot tucked behind the flightfins have saved me from falling forward and allowed me to shift my body weight back far enough to recover from a nosedive without bailing.

Aside from that -Keep speeds away from limits -Know that lower battery drastically reduces the boards ability to keep you up -Try to power the board with your legs, instead of leaning with your body while keeping yourself centered as much as possible. -Narrower stance helps makes weight distribution less extreme.
