The problem
A weak battery should not be the end of your EV
The battery is the single most expensive part of an electric car. A dealer-only replacement can run into millions of rupees, with long waits for an imported pack and little local support. The good news is that most of the time you do not need a brand new pack at all.
01
A full OEM pack is dealer-only on most cars, the priciest possible route, and often weeks away on import.
02
A failed module, unbalanced cells, or a tired BMS can be repaired or rebuilt for a fraction of a full swap.
03
EV packs are built to last around 15 years or 180,000 to 200,000 km, so a good rebuild gives the car years more life.
What we do
Complete lithium battery service, in one workshop
From a single failed module to a full custom pack, we cover every job an electric car battery can need.
Pack replacement and rebuild
A full replacement, or a rebuild that reuses your healthy hardware, sized to restore your original range.
Module repair and balancing
We isolate the failed module, replace or rebalance cells, and bring the whole pack back to an even state of charge.
BMS service and integration
Diagnose, repair, or replace the battery management system so charging, balancing, and safety limits work as they should.
Capacity and range upgrades
Where the platform allows, we add usable kWh so your EV travels further on a charge than it did when new.
Battery health diagnostics
A full health check covering capacity, internal resistance, and cell balance, delivered as a clear report before any work begins.
Cars we support
Made for the EVs on Pakistan's roads
Both of the brands leading Pakistan's EV shift run lithium packs we can service. If your car stores its energy in cells, we can almost certainly help.
BYD LFP Blade
Atto 2, Atto 3, Seal, Dolphin, Seagull, Sealion. All built on BYD's Blade Battery, an LFP design known for its heat tolerance and long cycle life.
Jetour CATL LFP
T2 PHEV, G700, X70L Shanhai. Plug-in hybrids running CATL lithium iron phosphate packs from 18 kWh up to 34 kWh.
Other EVs LFP / NMC
MG, Haval, Deepal, Changan, and most imported electric and plug-in hybrid cars. Send us the model and we will confirm the pack.
Driving something not listed here? Tell us the make, model, and year and we will confirm whether we can build, repair, or replace its battery.
Why local
Local rebuild versus dealer-only replacement
When the dealer's only answer is a full imported pack, you are paying the most for the longest wait. Here is the difference.
Dealer-only route
One option, top price
- Full pack only, even when one module failed
- Weeks of waiting on an imported pack
- No repair, rebuild, or upgrade path
- Highest possible bill
Hybrid EV Engineering
Right-sized to your car
- Repair, rebuild, or replace, your choice
- Work done locally in Islamabad, faster turnaround
- Option to add capacity and range
- Graded cells, matched BMS, workshop warranty
Know your cells
LFP or NMC, we build with the right chemistry
The two main lithium chemistries behave very differently, and the right choice depends on your car and how you drive it.
LFP
Lithium iron phosphate
Nominal cell voltage3.2 V
Cycle life2,000 to 5,000
Heat toleranceExcellent

Not sure which your car uses? We identify it during diagnostics and recommend the right cells for your range, budget, and conditions.
How it works
Four steps from worry to road
STEP 01
Diagnose
Bring in the car or the pack for a full health check on capacity, resistance, and cell balance.
STEP 02
Quote
A clear, itemised quote with your options to repair, rebuild, or replace, and what each one buys you.
STEP 03
Build or repair
Cells graded and matched, the pack assembled or repaired, and the BMS configured and tested.
STEP 04
Install and verify
Fitted, calibrated, range verified, and handed back to you with a workshop warranty.
Common questions
EV battery questions, answered
How long does an electric car battery last?
Most modern EV packs are engineered to last around 15 years, or roughly 180,000 to 200,000 km. The biggest stressor is frequent high-power DC fast charging, so charging at home on AC whenever you can is gentler on the pack. A healthy battery management system also slows degradation considerably.
Do I really need a whole new battery pack?
Usually not. EV packs are made of modules, and very often only one module, a set of unbalanced cells, or the BMS has failed. We can repair or rebuild just the affected part, which costs far less than a complete pack and gives the car years more service.
Which cars can you build or repair batteries for?
We work on BYD, Jetour, MG, Haval, Deepal, Changan, and most imported electric and plug-in hybrid cars. If it runs on a lithium pack, send us the make, model, and year and we will confirm.
Is a rebuilt battery pack safe?
Yes. We use graded, capacity-matched cells, pair them with a correctly configured battery management system, and test the finished pack for balance and safety limits before it goes back in the car. Every job carries a workshop warranty.
LFP or NMC, which is better for Pakistan's heat?
LFP, the chemistry in BYD's Blade Battery and most plug-in hybrids, tolerates high temperatures very well and has a long cycle life, which suits our climate. NMC offers higher energy density and better cold-weather behaviour. We recommend the right cells for your specific car and driving.
Where are you based?
We have two locations. Our head office is at Plot 315, Street 3, I-9/3, Islamabad, phone 0333 5435936. Our mechanical branch is on Old Airport Road, Faisal Colony, Rawalpindi, phone 0313 5222531. You can bring the vehicle to us, or send the pack, and we will start with a full diagnostic and a clear quote before any work begins.
