    Note:  
    Melasta's  development of high drain type of Li-polymer batteries ( LiCoO2 ) can bear max continuous charge rate up to 2C(Peak current 4C) and continuous discharge rate ranging from 10C to 40C. One of key features of  this Li-PO is that they will have a good plateau (Mid- point -Voltage ) compared with regular battery in discharge, obviously turns up for much more higher one, it's voltage keeps stable. The same principles apply to comparison between two high drain of cells with different rating. 

    Tabs: 
    Positive tab: nickel-plated copper ( Thickness:  0.2mm, width: 25mm,  length: max 30mm)
    Negative tab: nickel-plated copper ( Thickness:  0.2mm, width: 25mm,  length: max 30mm)
    (We can provide pure alumium tabs if required)
     
     
    Application: 
    High drain Lithium polymer batteries can be applied to RC Model, Formula Student Racing car, Hobby Racing car, UPS, E-bicycle, E-scooter, Electric Wheelchair, Power tools and other special products which need high drain design.
