2).Q: I am very sensitive to price, I am a wholesaler of battery packs, if I sell your battery packs in my city, the profit is very low, can I get a cheaper price? I can see that your competitors sell cheaper than you.
A: It is highly recommended that you compare with our competitors. In fact, there are also some suppliers who provide low-priced battery packs, but use cheap materials. Please pay attention to the cycle life and warranty, we have anti-vibration design and communication design. Maybe you know that the price of cylindrical batteries is much cheaper than square batteries.

The most important thing is that we can provide you with professional solutions according to your local market? Low profit? Don't worry, our engineer team will help you solve the problem.

3).Q: I saw the post saying that your company shows a warranty period of 5 years, so no matter what the battery pack is used for, it is 5 years?
A: No sir, maybe you know that the cycle life of the battery depends not only on the quality itself, but also on the discharge/charge rate and the actual temperature. So it is totally irresponsible if the supplier tells you the cycle life but does not talk about the actual usage. For room temperature 25℃ and 1C discharge and 0.5C charge, the cycle life of the battery pack can exceed 4000 cycles, with a warranty of 5 years, for energy storage use only.

A: Yes sir, our battery packs can be compatible with most brands of inverters on the market, please contact us and I will tell you more information.

They will be in good packaging, each battery is put into thick PE foam or bag, and then put into 5 layers of sturdy carton.

6).Q: Can it be used in series or parallel?

A: Yes sir, it can support up to 4 in series or parallel use without any additional equipment.
Due to the limitation of BMS, please be aware that the default model does not support simultaneous series and parallel connection.
