MATE X 48V 17.5Ah
Battery Rebuild
Restore your original MATE X battery with 65 brand-new premium-grade lithium-ion cells and a complete professional rebuild.
Bring Your MATE X Battery Back to Life
Is your MATE X battery losing range, cutting out under load, taking longer to charge, or simply no longer performing like it used to? You may not need to replace the entire battery.
Our MATE X Battery Rebuild Service keeps your original battery housing, mounting system and compatible external hardware while replacing the aging internal lithium-ion cell pack with 65 brand-new premium-grade battery cells.
48V 17.5Ah / 65-Cell Rebuild
The advertised price on this product page is specifically for our 48V 17.5Ah MATE X rebuild. This configuration uses a 65-cell lithium-ion battery assembly built from premium-grade cells.
Batteries requiring additional electrical repairs, replacement components, BMS work, connector repairs, or non-standard modifications may require an additional charge. We will contact you before performing chargeable work outside the standard rebuild.
65 New Premium-Grade Lithium-Ion Cells
The 48V 17.5Ah configuration is built as a 13-series × 5-parallel battery architecture, resulting in a total of 65 individual cells.
We completely replace the aging cell assembly rather than simply replacing a few weak cells. This gives the rebuilt pack a fresh, matched internal cell group designed for dependable everyday e-bike use.
What's Included
All 65 cells in the internal battery assembly are replaced with new premium-grade lithium-ion cells.
We rebuild inside your existing MATE battery enclosure so the original physical fit and mounting arrangement are retained.
Wiring, connectors, contacts and other serviceable battery components are inspected during the rebuild process.
The Battery Management System is inspected and tested. If replacement or additional repair is required, we will contact you.
The rebuilt battery is charged, balanced and performance-tested before being approved for return.
Your battery rebuild is backed by our 1-year rebuild warranty.
MATE X Compatibility
This listing is intended for compatible MATE X 48V battery packs using the 17.5Ah configuration.
MATE has produced different versions and configurations over time. If your battery label, connector, housing or specifications differ, please contact us with clear photos of the battery and its label before ordering.
Important: Send Your Battery AND Charger
Please include your original charger when sending your battery to us. Having the charger allows our technicians to verify charging operation and compatibility as part of the testing process.
You must also complete and include our Battery Service Intake Form .
How the Rebuild Works
Why Rebuild Instead of Replace?
A battery rebuild allows you to keep the original MATE enclosure and mounting hardware while replacing the component that normally suffers most from age: the lithium-ion cell pack itself.
- Keep your original battery housing and fitment
- Replace the entire aging cell assembly
- Avoid depending on an old or unknown used battery
- Reduce unnecessary electronic waste
- Professional testing before the battery is returned
- Backed by a 1-year rebuild warranty
We stand behind our workmanship. This MATE X battery rebuild is covered by a 1-year warranty on the rebuild service, subject to our battery service warranty terms and exclusions.
