Any downside if using 3s packs in series

[kenghock]

Hi everyone
I was looking a batt prices. Running 2 3s packs appears cheaper for the same capacity than one 6s batt.

I was wondering if there are any downsides to using batts in series. Apart from less flight time.

Hope to get your advice

Thanks Ken

3s+3s works the same as 6s.

Flight time is the same.

The two packs will need to be similar.

Downside = extra connectors

Downside, mismatch between packs1 and pack2. The weaker packs during usage will be the first to die after some use.
That is why a 6cells pack is more expensive than individual 2 set of 3s lipo packs .
The 6 cells are carefully balance and matched during manufacturing process.
