Got my first scooter, seeking long-term advice

I just took a ride from the shopping center to home on my new Segway Ninebot G2E (European model, max speed is 25 km/h) and thoroughly enjoyed the experience. The turning signals and buzzer functionalities particularly impressed me.

Although I'm uncertain about the superiority of the G30E model, its 900 EUR price tag in my country makes the G2E, priced at 720 EUR, an appealing choice.

Seeking guidance on battery maintenance, I'm currently charging it to 100%, as recommended every three months. However, I plan to limit subsequent charges to 80%. Additionally, I've configured the Energy Recovery setting to Strong.

I'm curious about the compatibility of charging cables. Is it safe to use any cable for charging the scooter? Moreover, I wonder if it's suitable for use on slightly wet roads during light rain (has IPX5 rating, right?).

Considering the eventual need for a battery replacement, I'm unsure of the timeframe for a professional replacement. Any insights or advice on this matter would be greatly appreciated.

Thank you all!
