We have multiple warehouses across the United States, in California, Texas, Georgia, and Kansas. The majority of our shipments will be sent from our California warehouse, and our shipping is extremely fast. If you live in California, you can expect to receive your package within 12 business days, based on our previous experience.

Our 12V batteries can connect up to 4 in series or 4 in parallel, allowing for a total of 16 batteries to be connected as 4 in series and 4 in parallel.

You can use the wattage consumption of power draw and runtime on the RV as a guide to selecting a suitable battery model. If you have any questions, please contact us at service@timeusbpower.com, and we'll be happy to assist you in finding the right battery for your needs.

Our battery's ideal operating temperature for discharging is between -20°C (-4°F) and 60°C (140°F), and for charging it is between 0°C (32°F) and 50°C (122°F).

It is determined by the battery's built-in BMS. A battery with a 100A BMS, for example, would have a maximum continuous charging/discharging current of 100A.
