Introduction When choosing an electric bike, one of the most important components is the battery. eSthira’s Raptric eBike features a 7.8Ah battery — but how long does that really last?

A battery rated at 7.8Ah (Ampere-hours) and 36V (Volts) provides about 280 watt-hours (Wh) of energy. This is a standard battery size for daily city commuting, offering a good balance of power and portability.

So what does that mean in real-world usage? The total range (how far you can travel on a single charge) depends on several real-life factors.

Let’s break it down.

🛣️ Battery Specs at a Glance

• Capacity: 7.8Ah / 36V
• Charge Time: 3-4 hours
• Average Range: 40 km per charge (based on terrain and usage)

In city traffic conditions like those in Bangalore, 35–40 km is a safe bet for regular use, especially with moderate pedal assist. If you use more throttle without pedaling, your range might drop to 30–35 km.

🧠Factors That Affect Battery Life

1. Riding Style – More throttle use drains the battery faster.
2. Terrain – Uphill rides consume more power.
3. Weight Load – Heavier riders or cargo reduce range.
4. Tire Pressure – Under-inflated tires cause drag.

Battery lifespan is measured in charge cycles. One cycle equals a full charge from 0% to 100%.

A high-quality 7.8Ah lithium-ion battery like Esthira’s typically lasts:

• ✅ 600–800 full charge cycles

• ✅ That equals roughly 2 to 3 years of daily use, if you ride 10–15 km per day

• ✅ With good care, it can extend up to 4 years

💡Tips to Extend 7.8ah Battery Life

• Here are some easy maintenance tips to extend both your range per charge and the overall battery lifespan:

  1. Don’t overcharge – Unplug once it reaches 100%

  2. Avoid draining to 0% – Try to recharge around 20–30%

  3. Use pedal assist wisely – Throttle-only rides consume more power

  4. Inflate your tires regularly – Low pressure = higher drag = more battery drain

  5. Store in a cool, dry place – Avoid direct sunlight or freezing temperatures

  6. Use the original charger – Third-party chargers may reduce performance or safety
