The aftermarket replacement battery market requires a level of precision that generic battery manufacturing cannot provide: exact dimensional matching to ±2mm, connector pinout verification, BMS parameter matching to the original discharge curve, and compliance documentation for warranty and customs purposes. Our precision manufacturing verifies replacement packs against the original specifications across all these dimensions.
Our matching process starts with the original battery label (voltage, Ah, model), connector photos, and if available, a sample unit for dimensional and electrical profiling. From that data, we produce a replacement that connects, fits, and performs equivalently to the OEM battery, with matching BMS cutoff curves, capacity ratings, and display communication protocols where applicable.
Every replacement battery passes the same quality control checks as our OEM production and ships with a 12-month warranty on cells and BMS, CE marking, UN38.3 transport documentation, and a warranty card template your team can customize. White-label packaging with your brand name, logo, serial number scheme, and instruction manual is available after MOQ and packaging scope are confirmed.

Frequently Asked Questions
How do I provide you with the specs to make a compatible battery?
Send us photos, the original battery label (voltage, Ah, model number), and connector photos. If you have the original battery, ship 1 sample to our factory for dimensional matching.
Can you produce white-label batteries for our brand?
Yes. Custom label, custom serial number, custom retail box, and custom instruction manual are all available. We can also program BMS parameters to match the original battery's discharge curve.
Do replacement batteries come with warranty documentation?
Yes. We provide warranty card templates, 12-month warranty on cells and BMS (standard). Custom warranty terms available for larger orders.
Are your replacement batteries safe: do they meet European regulations?
All our replacement batteries include CE marking (LVD + EMC), UN38.3 transport testing, and RoHS compliance. IEC62133 available on request. We do NOT use uncertified cells.
