After working on this 48V pack of 48 cells I am inclined to agree that fewer
Calb cells is more attractive, you can get them from Evlithium too. The
headway cells (38120P with screw terminals) I bought from them were cheaper
than buying direct from headway. The ones in this pack I am working on have
welded tabs, not friendly to work on. You can get plastic holders for these
cells that you build up like Lego, those with the straps and screw terminals
are much nicer to work on, neat too.
I did look at calb, but the 38120P cells have a 20C discharge rate,
to get the same allowable discharge current from calb you need something
above 100Ah I think it was. I have been looking at R/C packs from Hobbyking,
you can get these in up to 130C discharge rating. I had a Diahatsu charade I
was driving 5 kms to work and the same back, so I wanted a low capacity,
high rate battery. I had health problems so did not finish the project
though.

Buy direct from headway.

Be warned, by the time you pay for shipping and any associated fees, you get
a pack that has little or no warranty. Don't expect China to help deal with
any warranty claims.
After all is said and done, 38120S Headway cells aren't that much better
than some CALB cells. Depending on how many Ah you need, if you can do
40/60/100, then CALB are a much better deal. You don't have to worry about
all that bussbar.
This is coming from someone who's built a few large packs using headway. I'd
do it differently today.
