Yep, no LVC needed. That's what made me decide to go Li-ION. Almost as good as Lipo but less maintenance and care needed.
I have less experience on batts. I am worst even on NiMH side by side. I guest I should just buy the packs for now. The price I have to pay for being worst in assembling batt packs.
With all said and done. I think I will go with 5S2P or 3S2P+2S2P, being noob and all on BL setup.
