5: I'm very sensible in price, I am a wholesaler of battery packs if I sell your battery pack in my city, the profit is very low, can I get a cheaper price? and I can see your competitor sells cheaper than you.
A: It is highly suggested that you can have a comparison with our competitor. Indeed, there are also some suppliers that provide low-priced battery packs but use cheap materials. Pls pay attention to the cycle life and the warranty, and we have an anti-vibration design and communication design. maybe you know the price of a cylindrical cell is far low than a prismatic cell. besides, we also provide cylindrical cell solutions, pls contact us directly and we will tell you more. Most Importantly, we can give you a professional solution according to your local market. low profit? Don't worry about that, our engineering team will help you to solve it.
