Electric Bike Battery Cuts Out

The malfunction in the cells might be a result of aging improper battery management too many charge cycles or a manufacturing defect.

Electric bike battery cuts out. After charging all night it s still dead empty discharging problems. So overheating could make it cut out quite quickly. If you are experiencing intermittent power failures or any kind of power issues with your electric bike and your battery is the hailong 2 type. The motor controller is better able to lose heat which it also generates but can still get hot especially at over twice the rated continuous current.

For 44v batteries 46v is a good storage voltage. A massive voltage drop often means that one or more cells in your pack have gone bad. This is when the battery either won t charge or won t hold a charge. Since e bikes are battery powered the first logical place to start troubleshooting would be the electrical system.

Dis connect the battery from the charger and from the controller. A dead battery would be our first potential culprit. With discharge problems the main symptom is the bike completely dying under load and not starting again until the battery is disconnected then reconnected to the motor. Heat generated in the battery module isn t easily got rid of.

Store the battery at a median voltage instead of fully charged. E bikes work primarily like regular bicycles with a few extra electrical and mechanical parts to contend with. Heat will also increase the resistance of the links between the cells causing the voltage measured at the battery terminals to drop.
