Rechargeable 21700 battery cells - lithium - LFP - LiFePO4

Make: SINC
Capacity: 3000mAh

High quality LiFePO4 cells, only used for a few months, perhaps 30-40 cycles

Form factor: 21700
Cycle life down to 75% capacity: 4000 cycles

I can sell these individually for €2 each, or €1.50 each if you buy more than 100

Or much cheaper again if you buy higher quantities

Feel free to offer me €1 for PM and we can work out a deal

I also have 48V packs of these in 16S42P format, with 672 cells each, good for 6.5kWh usable. Ideal for home battery / solar battery. I used these packs in my own home battery until my recent upgrade

In the picture you can see 3 of these cells beside 1 standard 18650 lithium ion cell as used in power tools, laptop batteries, torches, vapes, etc.
