PCB or PCM is protection circuit board, usually for small battery, typical use is for digital batteries, like mobile phone battery,camera battery,mp3 player battery,GPS batteries,heated clothing batteries and so on. Most time, Its for 3.7V or 7.4V battery, It has four basic functions of over charging, over discharging, short circuit,over current.some batteries may also need PTC and NTC.

When it is cold in winter, cars tend to have starting problems. This is not much better with electric cars, which inevitably lose capacity of their rechargeable lithium-ion batteries at freezing temperatures. Now, Chinese scientists have offered a strategy to avoid plunging battery kinetics. In a study published in the journal Angewandte Chemie, they designed a battery system with a cold-enduring hard-carbon anode and a powerful lithium-rich cathode, with the important initial lithiation step integrated.

There’s a lot of research going on around battery technology as devices as diverse as smartphones and cars are increasingly held back by limited energy storage. Naturally, we report on interesting advancements in batteries frequently. There are lithium-air batteries, aluminum-graphite batteries, and even bacterial batteries. Rarely do we have to dredge up one of those old posts to talk about the next step toward commercialization because there isn’t one.

A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.

10k BZ 654165 7.4V 2000mah Rechargeable Lipo Battery pack were sent to Korea, this order began from 2014, now is the 18th order, the production took 20 days since ordering, Benzo paid attention to the quality control during production, from material inspection to battery cell inspection and assemble tests, every steps were strictly watched by QC staffs, the final tests before shipment showed that we got 100% pass, hard works got something in return.
