RD-

I like the fact that you bolded the discharge that stayed below the temp
cutoff for cell destruction.

Kudos,
B

RD,

A nice set of data. Do the results look similar to something else? Did you disassemble the pack, and see any cell ID?

Rod,

The Grayson and the Apex MK3 curves are very similar.

Grayson cells are imprinted:
KMBNK623496H
CG270084

B,

The bold face font is simply a mismatch between the CBA's resident font and my photoprocessor's font.
The photoprocessor text replaced erroneous cell ID - the CBA program is quirky - it won't let you change errors in cell ID once entered.

Correct me if im wrong, but from how I read this graph, during the discharge, the voltage is at 3.3V. Certainly, this voltage is normal.You can compare this with those from Thunder Power, they are also within this range at 13C.

At at 12C the GraysonPower Packs hang out at 3.5~3.4volts

Thanks RD,

Looks like we have a new Chinese cell 'on the block': Neosonic - KMB

The performance looks to be broadly in line with their rating and, as you say, similar to the Apex 2100.

Thanks for the testing RD,

Rod

B, Righto!

Rod, You're welcome! Thank YOU for the cell ID - I think I'll reference your post in the stickied "manufacturers" thread, if it's OK with you.

Lt., You've got a promising new entry in the LiPos sweepstakes, I think. Pricing will be important and we don't yet know the Neosonic's durability. Let me know if you want me to retain the cells I have left for durability investigation. I need to warn you it may be some time before I can get to that.

No problem - if I post it then it is public information.
