boosted mini x

hey everyone, i bought a boosted mini x in 2020 but got rlod in 2021. i’ve been completely away from this entire electric skateboard thing since then. i’m starting college this fall and i figured id try to see if i can get the board working again. what are the best things i can do to fix my battery, (can i do it myself or are there places i can take it) or is it even worth it with newer options out there? any help is seriously appreciated, used to love this thing back in the day.
