Dear Davide, I leave you in Vivian's hands, I'm sure you will come to an agreement., Vivian is professional in our product.

—— Davide Bet

Here is the signed PI. Thank you , We hope

—— Mr Ander

12V 110Ah battery pack for solar product I like your solar battery pack. Good quality and delivery fast.

—— Eyal Dolev

The battery pack is more atractive for us . May I receive drawing of other pack 12V 20AH with dimentional info ? I need 50pcs to test .

—— Nizamettin

We have received the battery packs and performing tests have passed . We are impressed by the assembly. it is almost the best one . thank you

—— Alexander Kozhushko

Pictures show a nice battery pack, performance is ok , We need serial connected 4cells (4S1P) configuration with protection circuitry

—— George Komisar

big thanks for your work, we got the cargos last week, it seems nice.

—— Johnny Black

I think it is a good idea to solve the problem, I am really appreciate you would like to help us.

—— Simone Kowalk

yes , we received the batteries and chargers last Friday, Everything looks great,well packed, no damage and dlivered in the time frame as promised.

—— Met vriendelijke groet

Thanks for your input, we have checked each and every think and on our side every thing is great. Just proceed to submit the company documents to get approval.

How to store lithium-ion batteries without long-term discharge and charge



Lithium-ion battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S. Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the production, storage and use of lithium metal have very high environmental requirements. Therefore, lithium-ion batteries have not been used for a long time. With the development of science and technology, lithium-ion batteries have now become the mainstream.
Lithium ion batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance-price ratio are superior to those of lithium-ion batteries. Due to its own high-tech requirements, only a few companies in a few countries are processing this lithium metal battery.
Lithium-ion battery: It is a secondary battery (rechargeable battery) that relies heavily on the movement of lithium ions between the positive electrode and the negative electrode to work. During charging and discharging, Li+ intercalates and deintercalates back and forth between the two electrodes: during charging, Li+ deintercalates from the positive electrode and intercalates into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge.
Lithium-based batteries are divided into lithium-ion batteries and lithium-ion batteries. Cell phones and laptops use lithium-ion batteries, which are commonly referred to as lithium-ion batteries. Batteries generally use materials containing lithium as electrodes, which are representative of modern high-performance batteries. The real lithium-ion battery is rarely used in daily electronic products due to its high risk.
The newly-purchased lithium-ion battery will have a little power, so when the user gets the battery, the user can use it straight, use up the remaining power and recharge it. After 2 to 3 times of normal use, the lithium-ion battery activity can be fully activated. . Here is a special reminder: Don’t misbelieve the rumors from the salesperson or the Internet, the new lithium-ion battery needs to be activated for up to 12 hours when it is used for the first time.
Lithium-ion batteries do not have a memory effect and can be charged as they are used, but it should be noted that lithium-ion batteries cannot be over-discharged. Over-discharge will cause irreversible capacity loss. When the machine warns that the battery is low, it will start charging immediately.
