Is it possible to build a 5S2P a-123 pack? I'm building a Balsa USA .40 Eindecker and would like to use a 5S2P pack for iy if possible. That way I can keep the prop diameter down to managable size. I just bought a CellPro 10s which has A-123 charge software but would like to field charge the pack using a simple power supply and diode. I also have a Whattmeter. What is recommended for a power supply?
BTW I plan to mount the pack in a semi permanent installation.

Yes you can build 5s2p packs using 10s tube...
You can even insert balancing taps...
I made 6s2p packs once upon a time; too long, now converted to 6s1p.
I use the MasTech HY5020E, good to 14s2p at full speed (20A).
I have set my limit to 12s2p, my balancer...
