[SELLING] K2 Batteries
#1
I have come across ~70 used K2 Energy K2B24V10EB 24V 10Ah Lithium Iron Phosphate Batteries with built in BMS.
https://www.superdroidrobots.com/product...4V10EB.pdf


The guts are 3p8s LFP26650EV http://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 the ones that make the grade the cost 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.

Man! And I don't have the $$ or the time to come get them. *sigh* That'd be a nice trip up to Maine.
Proceed with caution. Knowledge is Power! Literally! Cool
