Benzo Lithium Battery News

LiPo batteries (short for Lithium Polymer) are a type of rechargeable battery that has taken the electric RC world by storm, especially for planes, helicopters, and multi-rotor/drone.

1- Capacity: higher capacity means longer use time, if its for mobile phone, you can talk for more hours, and you can play more games, listen more songs Before you need to charge again.

2- Internal Impedance: High impedance can cause quick exhausting of power, itself can be a hidden reason of working current, the higher it is, the quicker the voltage will drop down.

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.

Last week, large lithium polymer battery product 3.7V 8Ah and 10Ah with PCM were delivered, big lipo batteries were always ordered in quantity of thousands because of their unique advantages of thin shape,light weight,high energy density, big discharge current, long work time, many customers liked to use them in power banks manufacturing for reason of big capacity, some customers liked to use them in applications of industrial applications such as lazer devices,testing devices,some other customers used them in portable medical equipment.

10k 18650 11.1V 2200mAh 1.5C lipo battery packs were sent to Korea, this order began from 2015, now is the 15th 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.

15k lithium polymer battery(lipo battery) 3.7V 1200mAh were sent to Germany this month for a tracking device.

15k 7.4v 5100mAh 40C lipo battery for RC models were sent to Belgium, this battery pack seems to be very hot in RC model fans in Europe, the demand for BENZO Energy high rate BZ5543125-2S2P had been increasing, over 30k of this battery pack were delivered to France, UK, Belgium, Hungary, Denmark in the past 6 months, its almost twenty percents of all BENZO Energy high rate battery export amount during these months.

2.5k motorcycle engine start up battery 12V 8Ah were sent to France, this battery is by high rate LiFePO4 lithium polymer battery technology, it has weight of only 1.4kg,about 30% of lead acid battery, but can discharge 210A max current, for motorcycle its very important and attractive to have both smaller size, lighter weight and higher discharge current with the same capacity.

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.

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.
