Before I blow myself up...
It's probably here somewhere, but I can't find it.
In very simple words how can I wire two single cell 3.7 volt Li-Po batteries in series to get 7.4 volts?
Due to space constraints I can't use a 7.4 volt Li-Po.
Not sure I understand....
If you have room for two single cell batteries, why not room for a two cell battery?
I mostly use two cell batteries.
I make up my own, as the two cell packs at hobby store never seem to be what I need.
You can almost always find Li-Pos that fit your space availability.
In many applications I mount the two cells seperately,
and wire them together to fit in available space.
I personally do not wire for balance charging, because of the size of connectors.
I do use battery protection circuits though,
as they afford protection against an individual cell being discharged to low.
In the many years I have been using Li-Pos I have not had any problems.
Picture shows a two cell battery with protection circuit I soldered up.
For size reference the cells are 402035's which is 4mm thick, 20 x 35mm each
(about 1/8" thick, 3/4"x 1 1/4")
