If you’re new to LiPo batteries, you may be unfamiliar with how to safely set the charge rate for your battery. The battery manufacturer will tell you what the maximum “Charge Rate” of the battery is. This information is different than the “C-Rating” which is usually expressed as a number on the front of the pack (20C, 50C, etc).

Generally there are three most popular charging ways as below:

1-CC charging(Constant current)

  The charging current keeps the same at a certain amount during the whole charging process, Most rechargeable batteries charge this way.

Lithium Polymer batteries (henceforth referred to as “LiPo” batteries), are a newer type of battery now used in many consumer electronics devices. They have been gaining in popularity in the radio control industry over the last few years, and are now the most popular choice for anyone looking for long run times and high power.

Lithium batteries mainly refers to the electrode cathode material used in the lithium element as the main active substance of a class of batteries.
Lithium-ion battery mainly as follows: energy density, uniform output voltage is high. Self-discharge is small, good battery, less than 2% per month (recoverable). No memory effect. The working temperature range is -20 ℃ ~ 65 ℃. Can quickly charge and discharge (2-5C), charge and discharge efficiency of up to 100%, and the output power (magnification discharge up to 60C or more). Long service life (more than 500 weeks). Does not contain toxic and hazardous substances, known as green batteries.

As a new lithium ion battery, it can gain its best performance only after twice or three times 100% DOD(depth of discharge) cycles. BENZO Energy recommend to charge 4 hours in the first three cycles, and don’t charge it for over 12 hours as traditional NiMH battery and NiCd battery. Because most rechargeable lithium batteries have protection circuit PCB/BMS, when its fully charged, the PCB will stop charging to protect it, it means its no use to charge any more if its full. Begin with the fourth time, you can charge one hour more after the indication of being fully charged.

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.
