FAQs
What does 51.2V mean for an EV bike battery?
51.2V is the nominal voltage commonly used in advanced lithium EV systems. It provides efficient power delivery, smoother acceleration, and better compatibility with modern EV controllers compared to lower-voltage packs.
Which capacity should I choose: 20Ah or 60Ah?
Lower capacities like 20Ah are ideal for short daily commutes and lighter bikes, while higher capacities such as 50Ah–60Ah are better for long-distance riding, heavier loads, and fewer charging cycles.
Is this battery compatible with my EV bike charger?
Yes. This battery is designed to be compatible with standard EV chargers that support 51.2V lithium battery systems. Always confirm charger voltage settings before use.
What makes EVE cylindrical cells better?
EVE cylindrical cells are known for consistent quality, thermal stability, and long cycle life. They deliver balanced performance and are widely used in professional EV and energy storage applications.
How long does the battery last?
With proper charging, temperature control, and normal usage, the battery can offer an operational lifecycle of up to 8 years, making it a cost-effective long-term investment for EV riders.
Which 51.2V capacity fits my daily riding?
Pick capacity by the km you actually ride, not by the biggest number on the list. The table below shows the range each pack gives, with prices checked in September 2026.
| Capacity | Range | Price |
|---|---|---|
| 20Ah | 30-40 km | Rs 56,000 |
| 30Ah | 50-60 km | Rs 82,000 |
| 40Ah | 65-80 km | Rs 103,000 |
| 60Ah | 100-120 km | Rs 150,000 |
If your round trip is 25 km, a 20Ah pack covers it with charge left for errands. If you ride 60 km a day, or carry a passenger on Islamabad hills, go 40Ah or 60Ah. A bigger pack also charges less often, which suits a rider who cannot plug in every night.
Voltage must match your controller. A 51.2V pack suits a bike set up for 51.2V. If your bike runs 48V, check the 48V Li-ion / LiFePO₄ EV Bike Battery (20Ah–60Ah) instead. For a 60V or 63V controller, see the 60V Li-ion / LiFePO₄ EV Bike Battery (20Ah–60Ah). Not sure what your bike takes?

What do buyers ask before ordering this battery?
Most questions come down to fit, warranty and delivery. Here is how each one works.
- Fit: custom packs are built to the shape of your bike or scooty battery compartment at no extra charge for the custom shape at a given voltage and capacity. The connector and charge port are matched to your existing setup.
- Installation: free professional installation at the I-9/3 Islamabad workshop. Riders outside Islamabad get wiring guidance with the pack.
- Warranty: 3-year warranty on every EV bike battery, and custom-built packs carry the same terms as standard packs.
- Delivery: Islamabad and Rawalpindi same-day or next-day; major cities 2-3 business days; other locations 3-5 business days.
- Testing: every pack is load tested and its BMS checked before it leaves the workshop.

Frequently Asked Questions
Is a 51.2V LiFePO4 battery better than a 48V lithium battery for an e-bike?
Neither is better on its own. A 51.2V pack suits a controller built for 51.2V, and a 48V pack suits a 48V controller. The voltage has to match what your bike already runs. What matters more is cell quality, BMS protection and the capacity you choose for your daily km.
What charger voltage should I use for a 51.2V e-bike battery?
Use a charger made for a 51.2V lithium pack. Do not charge a 51.2V battery with a 48V or 60V charger, even if the plug fits. Confirm the charger voltage setting before the first charge. If you are unsure, send a photo of your charger label on WhatsApp and we will check it.
How much does a 51.2V 30Ah e-bike battery cost in Pakistan?
The 51.2V 30Ah pack is Rs 82,000 as checked in September 2026, with a range of about 50-60 km. The 20Ah version starts at Rs 56,000. Prices are confirmed after your vehicle model is verified, and you can get a free quote on WhatsApp first.
Can you build a 51.2V battery to fit my bike’s battery box?
Yes. Custom packs are built to the shape of your bike or scooty battery compartment, with no extra charge for the custom shape at a given voltage and capacity. The connector and charge port are matched to your existing setup. Send your bike model and a photo of the old pack to start.
How do I know my EV bike needs a 51.2V battery and not 60V or 72V?
Check the label on your old pack or your controller. A 60V bike takes a 60V pack, and a 72V bike takes a 72V pack. If the label says 51.2V, this pack is the match. When the label is faded or missing, send a photo on WhatsApp and we will confirm the voltage before you order.
