General Battery cell # question...

[ZiklagPhilistine]

I am sending back a Castle Creations ESC for non-warranty repair. They want to know how many cells are in my battery/batteries. I was running (2) 7.4V, 2S, 20c 5000mAh batteries in series.

What is the answer to the question, "How many cells am I using?" I'd like to know how many total, and how many per battery.

I know this is a simple question but I want to fill out the form correctly so there are no mixups. I also have come to know that I won't get ridiculed for not knowing something most everyone else knows, so thank you all in advanced for the kindness you've shown in answering my questions!

Hey RP

Each cell in a lipo is 3.7 volts. Your 7.4 volt batteries therefore have 2 cells in each, which is what the 2S stands for.

If you've got 2 x 2S batteries in series then you have a 4 cell battery pack equating to 14.8 volts.

Hope this helps

Just to add to this

1S = 1 cell - 3.7 volts
2S = 2 cell - 7.4 volts
3S = 3 cell - 11.1 volts
4S = 4 cell - 14.8 volts

And so on

Hey there, RP! I'd just like to emphasize that we DO NOT and WILL NOT judge anyone for being a beginner. I like to use "beginner" instead of "newbie", lol. Anyway...each and every one of us were once a "beginner" and we asked a lot of questions, did some research, did some trial and error, and we all learned from it. You will too. Stick around buddy! We'll help ya!
