Expedition Battery Company Limited (EXB) make Li-ion battery packs all with high quality original cells with high “C” rate.
“C” rate shows the battery cells discharge ability. For example Samsung29E(2900mAh) 3C rate cells means it can discharge with 2900*3=8.7Amps continuous.
We have two series battery packs for sale:
Such as Samsung29E[3C rate],Samsung22P[4C rate], SonyV3[4C rate], Samsung25R[10C rate] or SANYO and Panasonic high C rate cells, Charge-discharge cycle life is more than 800 times.
We make LiFePO4 battery packs all with A123 18650 cells(30C rate).
Safety and long working life are the major features of LiFePO4 battery cells. It is more safer than “MCN” cells and charge-discharge cycle life is more than 1500 times. Shortcoming is low energy density.
Battery Manage System (BMS) is necessary for Li-ion battery packs, we design and make BMS by ourselves, we provide 10A/30A/50A/100A/150A models BMS for choice.
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.
What battery is the best for you
1. What is the rated power and max power of your motor or equipment?
2. What is the value of limited voltage and current of your motor or equipment?
3. Requirement of working time by each charge?
4. Simple calculations.
The rated power=500 Watts
The max power=1000 Watts
Working time= 1 hour
If 36V battery <42V max>
So you may choose 36V14Ah battery made of 2C rate cells matched a 20A BMS.
If 48V battery <54.6V max>
So you may choose 48V10Ah battery made of 2C rate cells matched a 15A BMS.
Or tell us your requirement, we will make the best choice for you.
