How do I replace the battery on my Widewheel 2019?

The battery is relatively straight forward to replace

remove the kick stand with one of the Allen wrenches that came with your scooter
screw open the bottom cover (different Allen wrench - also came with the scooter)
unplug the battery from the two controllers (the connectors are inside grey protective foam)
unscrew the battery input cable from the charging port.
remove the existing battery (it is taped to the inside of the footboard with double sided tape or velcro)
place the new battery inside (it comes with double sided tape or velcro)
reconnect the three cables
close up the scooter.

Please be careful with the connectors - make sure not to short circuit them (connect both poles to each other) with any tools you might be using.
