RE: Making A Lithium Cell Battery Pack.
Okay that I typed 7.4V when in series with two but my lithium is on 3.7V from start but fully charged they are over 4V each. And yes on what I read in my first post you see that in serie the voltage goes up but current is the same. Make 2 packs with 2 cells (2S2P) and solder positive to positive and negative to negative and you get 7.2V and a current with 1900mAh.
I'm not the best on english but I manage to read in my first post that if you take 2 packs in series you get the double voltage (was current) or if you that 2 cells in parallell you get double current.
It's only typos of course you take your readings from your cells and use them instead.
2S1P= 2x voltage and 1x current
2S2P= 2x voltage and 2x current.
