You are standing in your garage looking at a bike that has lost its punch. The old lead acid pack takes hours to charge and gives you half the range it did two summers ago. You have heard that lithium is the fix, and then you hit the real question: 48V or 72V?
This post settles the 48V vs 72V lithium battery choice for Pakistani riders. It covers what each voltage does to speed, range and price, which one your controller will actually accept, and what a pack costs here in Islamabad.
Quick answer
Is a 48V or 72V lithium battery better for an EV bike?
A 48V lithium battery suits standard e-scooties and keeps you legal and cheap to replace, while a 72V lithium battery gives more speed and hill pull for heavier riders and delivery work. Match the voltage to your bike’s controller: 48V bikes take 48V, 72V bikes take 72V.
48V vs 72V lithium battery: the short answer
For most riders in Pakistan, 48V is the practical choice. It is the most common system on e-scooties and small EV bikes, it keeps your paperwork simple, and a replacement pack costs noticeably less. A 72V lithium battery is for riders who want more top speed, better climbing with a load, and who own a bike built for 72V from the factory.
Voltage is not a quality upgrade. It is a system match. Put a 72V pack on a 48V controller and you risk frying the controller. Put a 48V pack on a 72V bike and it will feel flat and may not even start.
48V vs 72V lithium battery comparison table
Here is the same choice in numbers. Prices are for the 20Ah pack. Larger capacities cost more and are quoted when you book.
| Feature | 48V lithium pack | 72V lithium pack |
|---|---|---|
| Typical bike | E-scooty, small EV bike | Full size EV bike, delivery bike |
| Speed feel | Steady city pace | Higher top speed, stronger pull |
| Hill climbing with load | Fine for one rider, struggles two up | Handles a second rider and cargo better |
| Price, 20Ah pack | Rs 56,000 | Rs 79,000 |
| Controller match | 48V bike, 51.2V where allowed | 72V bike, 76V where allowed |
| Best for | Daily short commutes | Long routes and delivery work |
Both packs use the same EVE cells, the same smart BMS and the same 3-year warranty. The difference is the system they are built for, not the build quality. You can see the full range on the EV Bike Battery page.
What does voltage actually change on a Pakistani road?
Voltage sets the push. More volts means the motor spins faster for the same throttle, so you feel quicker acceleration and a higher top speed. Capacity in Ah sets how long that push lasts, so range comes from Ah, not volts.
On a flat road in Islamabad or Lahore, a 48V bike feels calm and predictable. On the Margalla Road climb or a flyover with a passenger, a 72V bike holds its speed where a 48V bike starts to fade.
How far can a 48V 20Ah lithium battery take an electric bike?
A 48V 20Ah pack gives most riders a full day of short city trips, roughly a commute and errands, before it needs charging. Heavier riders, hills and hot afternoons all pull that down.
If your daily run is longer, step up in Ah rather than in volts. A 48V 40Ah or 60Ah pack keeps your controller, your wiring and your paperwork untouched while giving you more distance per charge.
The same logic applies on 72V. A 72V 20Ah pack and a 72V 60Ah pack run the same speed, but the 60Ah pack keeps going much longer. For delivery riders doing back to back orders, capacity is the number that decides whether you finish the shift.
Which voltage does your bike’s controller allow?
Your controller decides. A 48V bike takes a 48V pack, or 51.2V where the controller allows it. A 60V bike takes 60V, or 63V where allowed. A 72V bike takes 72V, or 76V where allowed. Never jump a full step up.
Can I replace my lead acid battery with a 48V lithium battery on my e-scooty?
Yes, and this is the most common upgrade we do. A 48V lithium pack drops into the same space as the old lead acid set, weighs much less, and lasts far longer.
Lead acid and gel packs last about 300 to 500 charge cycles. Our lithium packs are rated at 4000+ charge cycles. That is the real reason riders switch.
Note that Evee electric bikes ship with graphene batteries, which are an enhanced lead acid chemistry, not lithium. If you own an Evee, the upgrade path is still a proper lithium pack matched to your controller. We also fit Vlektra, MS Jaguar, Metro, Revoo, Jolta, Road Prince, OKLA, Benling and Crown, and other brands on request.
What is the price of a 48V or 72V lithium battery in Pakistan?
The 48V pack starts at Rs 56,000 and the 72V pack starts at Rs 79,000 for the 20Ah size. The 60V pack sits between them at Rs 67,000.
Larger capacities cost more and are quoted when you book. There is no online payment. The exact pack, price and fitting date are confirmed with you first.
| Pack | Price, 20Ah | Typical use |
|---|---|---|
| 48V / 51.2V | Rs 56,000 | E-scooty, short daily commute |
| 60V / 63V | Rs 67,000 | Mid size EV bike |
| 72V / 76V | Rs 79,000 | Full size bike, delivery work |
Every pack comes with a 3-year warranty and 1 year of free service, with no fine print. Free professional installation is done at the I-9/3 Islamabad lab, and nationwide delivery is available in safe packaging.
When should you choose 72V over 48V?
Choose 72V if your bike was built for it and you need more speed or more pull with weight. Choose 48V if your bike is a standard e-scooty and your rides are short.
How to make a 72V lithium battery work on your bike
You do not build a 72V pack at home. You match one to your bike. The work is in the controller, the wiring and the BMS setup, and that is what we do at the workshop.

Frequently Asked Questions
How far can a 48V 20Ah lithium battery take an electric bike?
A 48V 20Ah pack covers a normal day of short city trips for most riders, roughly a commute plus errands, before it needs charging. Range drops with a heavier rider, hills and hot afternoons. If your daily distance is longer, move up to 40Ah or 60Ah rather than changing voltage.
What is the price of a 48V lithium battery in Pakistan?
The 48V and 51.2V pack starts at Rs 56,000 for the 20Ah size. Larger capacities cost more and are quoted when you book. The price includes a 3-year warranty, 1 year of free service and free professional installation at the Islamabad workshop.
What is the price of a 72V lithium battery in Pakistan?
The 72V and 76V pack starts at Rs 79,000 for the 20Ah size. Bigger capacities are quoted on booking. It uses the same EVE cells and smart BMS as the 48V pack, with a 3-year warranty and free fitting in I-9 Islamabad.
Can I replace my lead acid battery with a 48V lithium battery on my e-scooty?
Yes. A 48V lithium pack fits the same space as the old lead acid set, weighs much less and lasts far longer. Lead acid and gel packs last about 300 to 500 charge cycles, while these lithium packs are rated at 4000+ cycles. Wiring and the BMS are checked during fitting.
Is a 72V lithium battery better than 60V for an electric bike?
It depends on your controller. A 72V pack gives more speed and hill pull than a 60V pack, but only a bike built for 72V should take one. If your controller is rated for 60V or 63V, stay there. Send your bike model on WhatsApp and the right voltage is confirmed.
How to make a 72V lithium battery for an electric bike?
You do not build one at home. The pack is assembled with matched EVE cylindrical cells and a smart BMS, then fitted to a bike whose controller is rated for 72V. We handle inspection, assembly, BMS setup, wiring check and a road test at the I-9 Islamabad workshop.
Final Thoughts
The short version:
- Match voltage to your controller first. 48V bike takes 48V, 72V bike takes 72V.
- Voltage gives speed and pull. Ah gives range.
- 48V is cheaper and suits short city commutes. 72V suits long routes and loads.
- Rs 56,000 for 48V, Rs 67,000 for 60V, Rs 79,000 for 72V, all 20Ah.
- Lithium lasts far longer than the lead acid pack it replaces, and every pack carries a 3-year warranty.
