FAQ & Support

Q1.When can I receive my ebike battery or e bike battery after ordering?

the E-bike batteries are in stock in our Germany warehouse, and our ebike battery / e bike battery orders ship directly from Germany. Delivery takes 1–2 working days within Germany and 2–5 working days to neighboring EU countries, with no sea freight or customs clearance delays.

Q2. How are the shipping cost and safety guaranteed for an electric bike battery or electric bicycle battery?

Your electric bike battery will be shipped from the nearest overseas warehouse via UPS / FedEx / DHL. Shipping costs are clear and transparent. All lithium ion battery packs are stored and packed according to lithium battery regulations.

Q3.Does the price of this ebike battery include all costs? Are there any extra taxes or fees?

Our ebike battery / electric bicycle battery ships from local overseas warehouses, so no import customs duty is required for in‑stock orders.

However, local sales tax (such as VAT or sales tax) is borne by the seller, and the final price shown on the
product page already reflects this cost. There are no hidden fees to be paid by the buyer.

Q4. Does this ebike battery pack come with a charger and accessories?

Our ebike battery pack is usually shipped as a complete kit. The package normally includes the battery pack, matching charger, and
mounting accessories or adapter cable. Please refer to the product page for exact contents.

Q5.Do you support dropshipping or small‑batch orders for ebike batteries?

Q6.Do you support dropshipping or small-batch orders?

Yes, we support dropshipping and small‑batch orders for ebike batteries. Orders are shipped locally from our overseas warehouses. Neutral packaging is available, and private label is supported for some models.

Q7.My bike is [brand/model]. Can I use your ebike battery? Will this electric bike battery fit my bike?

Compatibility of an ebike battery mainly depends on voltage, size, and connector type. Please send us voltage (V), capacity (Ah), battery dimensions, and connector photos. In some cases, the same pack can also work as an electric scooter battery or electrictricycle battery, if specs match.

Q8.How many Ah should I choose for my ebike battery or e bike battery?

If you are satisfied with your current range, choose a similar ebike battery capacity. For about 30% more range, choose ~30% higher Ah, e.g. 48V 20Ah battery or 72V 20Ah battery. Higher Ah means more weight—please balance range and comfort.

Real capacity. Real safety. If you’re unsure — just ask.
