I would say that's probably about right.

Which battery do you have, LiFeP04 duct tape version or the Aluminium Rack Pack?

Re: End of Charge Voltage

I've just double checked the specification for your battery, and the end of charge voltage for those cells should be 4.2V±0.05V.
As your 36V 16Ah pack contains 40x4Ah cells in 10S4P configuration, the recommended end of charge voltage for the complete pack is 42V±0.5V.

Therefore your reading of 41.6V confirms that the battery has been fully charged. :)
