We have own factory in China, are mainly engaged in LiFePO4 and lithium-ion battery business, which is very suitable for RV, Caravan, Solar, Marine, Home Storage and Off-Grid. 

We also set up our warehouse in CA,USA, so we can provide quick delivery and high-quality professional after-sales service, such as free returns and exchanges, please just feel free to contact us and we are glad to offer help.

FAQs

1. Where do you ship from?
We have warehouses in the California,USA. For United States customers,usually the battery will be sent out within 1 working days after you place the order.
For the customers outside USA, we can ship from China directly.

2. What should I do if my package is damaged or defective?
We have analyzed and tested each battery before it is ready for sale. However, sometimes batteries can be damaged or defective due to improper handling during shipping or delivery.
If, unfortunately, the battery you received is damaged or defective, don't worry, feel free to contact us at vicky@jinstartech.com. We will always try our best to provide you with the best solution.

3. Are CHINS batteries safe?
All the CHINS lifepo4 batteries are made of non-toxic material and don't give off dangerous or hazardous fumes, which makes it safe for you and the environment too.
Additionally, all our batteries are with the built-in Battery Management System (BMS) which enables safe use. The BMS can protect the batteries from overcharge, over-discharge, over-current, and short circuits with excellent self-discharge rates, with built-in high-temp cut-off prevents charging over 158 °F (70 °C).
And our batteries have passed the required certificates, with a full quality inspection before delivery to ensure that our battery is a trustworthy product.

4. Can CHINS batteries be used as a starting power source?
No, as our batteries are not designed for starting, we don’t recommend using these batteries for starting. It may damage the batteries in long-term use if used as a starting power source.
