Q: Order Processing

1. Normal processing can take 2 business days, if the order doesn't need further payment verification & approval. During the holiday season or if the batteries are out of stock, it will take longer time.

If you need to have your order ship out the same day, you must call our customer service at 510-525-2328 (M-F between 9:00AM-2:00PM) to check if item is available to ship out the same day. We charge a $50 - $100 expediting fee. Customized items, Polymer and Li-ion battery pack, might take up to 2-3 weeks for assembly and testing. 

Please bear in mind that shipping times within US (UPS/Fedex)represent the time it normally takes packages to arrive from the day of shipment, not the day of submission, and do not include non-business days (i.e., Saturdays, Sundays, & holidays). Thus, for example, an order for UPS/Fedex 2nd-day delivery placed on Thursday could take until next Tuesday to arrive at its destination, assuming processing is completed within 24 hours and the package ships out on Friday (Friday + 2 business days = Tuesday). It could take longer if the order cannot be process in time to be ship out on Friday. For orders placed on Saturday and Sunday, most of them will be ship out on Tuesday since large amount of orders come in during weekend. When the items have been shipped out, you will get a notice via email. So please make sure to provide a valid email account.

2. We do generate the shipping label prior to shipping the order. Even though an UPS/Fedex tacking# is available to you , it does not mean the order is ready to ship out.

3. Our shipping label are automatically generate by our system. If you want to use your own UPS/Fedex account, we need to do it manually and there will be $10 handling fee for that.

4. We don't use USPS to ship item due to USPS does not provide a good tracking system. However, if you still prefer to use USPS to ship then we are NOT liable for any damage/ miss shipment and we will charge you $5.00 + whatever USPS shipping cost for handling this.

Important: If your order contains Li-ion battery, Lithium battery or polymer battery, we cannot ship by USPS. It has to be UPS or Fedex.

If this is acceptable to you, you can just place order using UPS/FedEx and then we can refund you the difference using USPS to ship to you. Please enter on the comment section -  ' I like to use USPS to ship and willing to accept the risk of loss or damage shipment.'  Also, please send me email with your order # so I can follow up for you.

5. UPS/Fedex pick up packages at 4:30pm every business day. The carrier will update the tracking information 24 hours after they received the packages. That means if you received the shipping confirmation by email on Monday evening, you can check the status of your packages on Tuesday evening.
