Line Overview

Built Around 21700 Cells and In-House BMS

Europe sells roughly 5.1 million e-bikes a year, and the global e-bike battery market is on track from $12.3B in 2025 to $46.1B by 2035. Packs built on the 2020–2023 sales wave are now entering their 3–5 year replacement window — which is why OEMs and fleet operators buy against a cell brand and a BMS spec, not a catalog photo.

Cell options — Samsung 50G 5000mAh or LG 4800mAh 21700 for energy density; A-grade 18650 for cost builds; LFP custom where 2,000+ cycles beat weight.
In-house BMS — 20A, 30A, 45A, 60A or 80A boards with five to six protection layers: overcharge, overdischarge, short circuit, overcurrent and temperature.
Discharge ratings — 20–40A continuous with 35–45A+ peaks, matched to 250W–1500W motors.
Fast charge — 0.5C charging returns 50% capacity in 2.5 hours (measured on the 48V 20Ah reference build).
Environment — -20°C to 60°C operation; a 48V 20Ah pack weighs about 4.8 kg.

Customization Process

From Motor Spec to Pack Design

Requirement Review

Send motor power, mounting envelope, range target and annual volume. An engineer replies within 24 hours with the platform match — series count, cell brand and BMS class.

Proposal & Sampling

Cell configuration, BMS profile, enclosure drawing and quotation in 2 working days. Sample packs follow in 15–20 days in your chosen format and connector set.

Validation

Samples run your duty cycle: fast-charge profiling, temperature tracking and vibration screening, with EN 15194 and IEC 62133-2 test alignment documented for your file.

Production & Export

30% deposit starts the line; 100–500 units deliver in ~15 working days. UN38.3, MSDS and Class 9 documentation ship with every order — sea freight by default, air at 30% SoC under PI965.

Buyer Questions

Light-Electric Packs, Answered by the Numbers

Can your packs go through EN 15194 certification?

We build and document for it. Packs ship with the electrical-safety construction file your notified body needs for EN 15194, plus UN38.3 transport certification and IEC 62133-2 through the CB scheme where your market requires it. Cycle and discharge data from our end-of-line testing supports the submission.

NMC or LFP for two-wheelers?

NMC 21700 (Samsung 50G, LG) where energy density decides the design — 700–1,000+ cycles, a 48V 20Ah pack at ~4.8 kg. LFP where duty cycles are punishing: fleet and swap packs reach 2,000+ cycles with a wider thermal margin. We quote both against your replacement economics.

Can you mold a custom housing and connector set?

Yes — custom enclosures, down-tube shapes and connector sets (XT60, Anderson or proprietary) run from 200–500 pcs depending on tooling, with sample fees credited against the first order. Standard-format packs start at 10 units.
