i meant 4p !!!!!
very sorry, so sorry
I was of course measuring whole 4 cells connected together.
So i had a response from seller, he stated that many cells like sanyoGA or mj1 cames with 3.5-3.6 and it is typical.
I got batteries from local vendor here in my city.
Labels printed on cells indicate that they were produced on III quarter of 2017. Do you think it is too old to be used? In theory lets assume they were stored in circa 20 degree Celsius, and since produced 12 months passed. How many % of capacity are lost?
