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).

Yes.

BENZO Energy has professional battery factories to produce lithium battery cells and battery packs, our cell factory produces lithium ion battery (Li-ion)cells, lithium polymer battery (lipo/li-polymer)cells,  and LiFePO4 battery cells, 3 years ago, we also got ability to produce one of world earliest LTO(Lithium titanate)battery cells, monthly capacity reaches almost 10 million battery cells.

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.

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.

LiPo batteries offer a wide array of benefits. But each user must decide if the benefits outweigh the drawbacks. For more and more people, they do. In my personal opinion, there is nothing to fear from LiPo batteries, so long as you follow the rules and treat the batteries with the respect they deserve.

This guide was written after many hours of research. It is as accurate as I can make it without actually being a chemical engineer (though, in researching this article, I did talk to a few of them). That said, this guide isn't intended to be taken as definitive. It is a living document, and as common knowledge regarding LiPo batteries changes, so too will this guide.

Let's first talk about the differences between LiPo batteries and their Nickel-Cadmium and Nickel-Metal Hydride counterparts.

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.

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.
