3pk
reason for asking i have some li.soci2 cells are size aa and 2500 mah the problem is they are 3.6v each cell so to put 8 of them in a 3pk might be a little silly but i tested them in an acoms 2.4 controller it worked fine but hummed not sure if it did before any way i want to put them to good use but am too scared to fry my 3pk any other suggestions what i can use them for seems a shame to waste
