I have come across ~70 usedK2 Energy K2B24V10EB 24V 10Ah Lithium Iron Phosphate Batteries with built inBMS.
https://www.superdroidrobots.com/product_info/K2B24V10EB.pdf
The guts are 3p8s LFP26650EVhttp://liionbms.com/pdf/k2/LFP26650EV.pdf
I am testing each one for capacity by charging to the manufacture spec of 29.2V @3A
Discharging at 4A to 21V.
The Average Ah results have been between 7Ah to 8Ah.
Here is a typical discharge curve.
Anything below 6Ah I consider not good. (Unless someone wants them at a reduced cost) Please let me know.
For theones that make the gradethecost is going to be $50.00 each plus shipping which unfortunately is around $20.00 each.
Local pickup is also an option If you are close to Portland, Maine USA area.
Any questions ask here or PM me.
