Could a lithium battery powered scooter or ebike be remotely overloaded?

Or send a signal through the riders device to lock the asset while in motion, or accelerate on its own...

They are responsoble for their app security, not tour phones or networks.

it would be easy to remotely turn on the device and let it run the battery down. These batteries are not supposed to be run all the way down and it will damage the battery. Sometimes causing them to explode.

perhaps but why?

Are you targeted as the leader of the ebike and lithium scooter cabal OP?

yes, a few years back this was secretly being tested on Drive By Wire cars

remember when Toyota had all those run-a-away cars and tehy were blaming the floormats

NO

some group was sending signals to the chips to increase the speed

Yes these chips are designed to pickup signals...from??

well i can boot into the bios and overclock/overvolt this pc im sitting at to self destruct in 30 secs. So its more of a level of access rather than possibility, short answer, of course.
