When received the order. Check if the packing is good, if any damage on the packing, take a clear photo or video, feedback to your sales. Unboxing the package, check if the items inside are good, if any damage, same take clear photos or video, feedback to your sales. Check the labels on the battery, make sure it's the battery that you are ordering. Plug in the charger, if the BMS is with bluetooth, scan the QR code on the battery, download the app, connect the battery and check the status of the battery. if you have any question on connecting the battery, you can contact your sales, they will help. Charge the battery to full before using. if the voltage difference is large(≥0.01V), please wait for the balance complete(only battery with bluetooth can check the voltage difference). Make sure the postive and negative pole are correct when connecting to your bike.

After the order is shipped, we will have a tracking number and checking website for you to check. If any questions about the order, please contact the sales who handle your order.

By sea shipping time is generally 30-35 working days. By air shipping time, 9-12 working days to United States, 10-13 working days to Canada, 12-15 working days to Europe. NOTE: if the packages get checked by customs, the shipping time will increase.

If any problem with the battery, please contact your sales, send the invoice number and descripe your problem. We will help to solver the problem.

Warranty one year. Artificial damage won't support the warranty. Impacting, falling, soaking, modifying the parameters of BMS.

To order a battery, please get contact with AMORGE sales, they will help to confirm the battery details, payment info and shipping details.

Cubiod batteries without iron box usually takes about 3-4 working days. Complicated and shaped batteries will take 4-5 working days. Batteries with iron box will take 3 or more days to customize the iron box.

We can accept the following payments: Alibaba trade insurance. Paypal. Bank transfer.

1. Voltage (V). 2. Expected capacity (AH). 3. Continuous discharge rate and peak discharge rate (AMP), or send the specfications of your controller and motor. 4. Battery sizes or battery space size, length, Width, Height, or drawing with dimensions.

1. Avoid overcharge and over discharge. Advice the capacity remains between in 20%~80%, avoid full charge or full discharge. Overcharging will accelerate the aging of electrode materials, while over-discharging may reduce internal chemical activity. 2. Standardize the charging process‌ When charging, connect the battery first and then the power supply. After fully charged, disconnect the power supply first and then unplug the plug to reduce the damage to the battery caused by the current shock‌. 3. Stay away from extreme temperatures High temperature will accelerate the volatilization of electrolyte and decomposition of electrode, while low temperature will increase internal resistance and drop capacity. It is recommended to use and charge at room temperature (10-30℃). In summer, it is necessary to let it stand for cooling before charging. In winter, avoid long-term exposure to low temperature and direct charging. 4. Select the appropriate charging device 1) Prioritize the use of original chargers‌ Different devices have different voltage and current parameters. Non-original chargers may cause unstable voltage or excessive current, affecting battery health‌. ‌2) Regularly check the status of charging equipment‌ Ensure that the charging port is clean and free of oxidation to avoid abnormal heating caused by poor contact‌. 5. Improve usage habits ‌1) Reduce high-load scenarios‌ Frequent high-current discharge (such as rapid acceleration, high-power operation) will accelerate battery aging. It is recommended to use it steadily and distribute the load reasonably‌. ‌2) Keep it half-charged during long-term storage‌ If it needs to be idle for more than 1 month, it is recommended to maintain the power at about 70% (voltage about 3.85V* numbers of series, if battery is 20 series, voltage about 77V) and recharge it every 1 months to prevent deep discharge‌. 6. Keep the battery clean‌ Regularly clean the dust and electrode oxides on the battery surface to prevent leakage or poor contact‌.

Without metal box, production time for one battery is about 7 days. With metal box, one battery is about 10-15 days.
