Can removing your battery kill your controller?

[CocoPlops]

Afternoon all,



A friend of mine’s LED controller started acting funny—turning the system off, etc. Then he tried to update it, but unfortunately, it turned off during the update process then the motor won’t turn on. So, he took it to his local dealer. They said they couldn’t get it to work at all. They tried replacing the controller, testing the battery on another bike, and trying another battery in his bike, but still got nothing.


Then, all of a sudden, he gets a call today saying the issue happened because he was taking the battery out of his bike every night, and the LED controller died due to not being charged.


I don’t think that sounds right, to be honest.


Thanks in advance

Yeah, nah. That's not how it works. Sometimes the batteries in the controller go bad and need replacement. But there are so many variables in this story, that it's impossible to tell for sure what happened. But if the bike is now up and running, that's what matters.

I have heard that some bikes have a rechargeable battery in the on/off switch. If the bike is left for a while without being used, the battery discharges and the bike, will not switch on. It might be something similar.

The Bosch LED Remote controller has an internal battery which is normally charged during rides. If you keep the main motor battery disconnected long enough the controller will lose its charge and can’t turn the bike on anymore. The LED Remote has a covered service port that can be used to charge the internal battery. You will need an USB Type-C charging cable. The battery is very small with 75 mAh @ 3.7V and won’t last long if not charged.
