Battery Guardian Live – E-Scooter & E-Bike Battery Health Checker

The Battery Guardian Live is an interactive web tool designed to monitor and predict the health of your electric scooter or e-bike battery in real-time.
By entering basic parameters such as nominal voltage, current voltage, battery capacity, number of charge cycles, and average monthly usage, users can get an instant estimate of battery health, remaining cycles, and approximate months of operation left.

The tool features a dynamic chart that visualizes battery degradation over time, helping riders understand when a battery may require replacement.
In critical conditions (battery health below 50%), the interface provides a visual warning by flashing the chart and text in red, ensuring users are immediately alerted to potential battery issues.

Battery Guardian Live also integrates with a Service Worker to enable background monitoring and notifications, making it a comprehensive assistant for battery maintenance and longevity.
