Ok, so I have 2 Kokem 2000mah (15C) 3s packs that I've been running in parallel 3s2p but I would like to run my Axi on these but its not really enough voltage to get performance out of this motor (4120/14) so can I buy a 2s pack and add it in series for 5s or will I have to also add another 2s pack parallel? I guess what I'm saying is you can add odd number of packs in series but not parallel? so it would be 5s2p? I'm confusing myself, how about you? BG
