This guide provides essential charging tips to help you get the best out of your e-bike battery.

1. Charge Before the Battery Gets Too Low

Avoid letting the battery drain below 15–20%. Deep discharge reduces battery life.
Best practice: Charge when it reaches 25–30%.

2. Don’t Overcharge Overnight

Unplug the charger once the battery reaches 100%.
Overcharging generates unnecessary heat, which shortens battery lifespan.

3. Use ONLY the Original Sando E-Bike Charger

Each charger is designed with correct voltage & current output.
Using a non-original charger may cause battery damage or safety risks.

4. Charge in a Cool, Dry Place

Heat is the biggest enemy of lithium batteries.
Avoid charging in direct sunlight or closed, hot rooms.

Ideal charging temperature: 10°C to 30°C

5. Let the Battery Cool After Riding

After long or fast rides, the battery may be warm.
Allow 15–20 minutes of rest before plugging in the charger.
