Notes
Nominal voltage is quoted as 48 V. Specifications are indicative and may be updated without notice. Capacity, communication protocol, connector and housing can be customised to order.
Matching this pack to your bike
48 V nominal means a 13-series build, and the current rating is the number to check first: 45 A continuous with a 70 A pulse suits controllers from 250 W up to roughly 1500 W, covering commuter e-bikes, cargo bikes and light delivery builds. If your controller is set to draw more than 45 A continuously, the BMS will cut out under sustained load even though the 31 Ah capacity looks generous on paper.
At 1483 Wh and 8.5 kg the pack is light enough for a down-tube or rear-rack mounting, which matters for retrofits: check the frame opening and the rack rating before ordering. For sizing by use case rather than by capacity, see e-bike battery packs.
Cells, BMS and protection
The pack is built from S31 cells in a 1P13S configuration at 172 Wh/kg, with a BMS covering over-charge, over-discharge, over-current, short-circuit and temperature protection, and single-wire communication for basic state-of-charge reporting. It carries GB 43854-2024 and 3C certification – the standard now required for e-bike batteries sold into China, and a useful quality signal for buyers elsewhere.
Ordering, samples and shipping
Capacity, communication protocol, connector and housing can all be changed to order, so a sample built to your drawing is usually the fastest way to confirm fit before a production run. Small trial orders are supported. Finished packs ship as Class 9 dangerous goods under UN3480 with UN38.3 test reports and MSDS; if the standard housing does not fit your frame, see the custom pack process.
