    Default Recovered lipo batteries

    Back-story: These lipo cells were recovered/removed from various laptop/netbook/players/tablet devices, returned due to faults of one kind or another inside warranty, and then deemed BER. As such, these lipo cells have seen less than one year (often only a number of months) in active duty, so despite their manuf. date of 2017, the (more than several..) of these cells I tested, still deliver better than 90% of the stated capacity (many are 95% of stated). They all incorporate charge protection circuitry etc, the 1S2P types include a thermistor for charge control monitoring. I would imagine the max discharge current rating of the batteries is 2 ~3C depending on type.

    Apart from replacing dead lipo batteries in similar or other devices, hobbyists/makers/tinkers might find these cells useful..ie; I've built a couple of arduino based clocks/tablelamps that fallover to these in event of mains power loss... where-ever flat and thin has to work =) See image below;



    Sizes expressed as thickness X width X length in mm

    (top left) 2.8 X 83 X 90 -- 2500mAh -- $0.50 each + postage [<20 available]
    (middle left) 3.0 X 85 X 150 -- 5000mAh -- $1.00 each + postage [<10 available]
    (bottom left) 3.0 X 110 X 140 -- 5000mAh -- $1.00 each + postage [>20 available]
    (top right) 3.9 X 100 X 205 1S2P -- 10,000mAh -- $1.50 each + postage [>20 available]
    (bottom right) 3.0 X 128 X 140 1S2P -- 6600mAh -- $1.10 each + postage [<10 available]

    Buy 3, get 1 free - buy 5 get 2 free -- all offers considered =)

    Postage == whatever it costs, based on dimension/weight of the order package, to where-ever you are from here in SE Qld. The 5000mAh cells are about 100grms , 175grms for the 10,000mAh.
