V1 started with these same LiPos, then I built the Headway packs which couldn’t supply the current I needed, and now back to the LiPos until I have saved enough money to build a replacement Li-Ion battery pack.
If I wanted to try LiFePO4 again, I’d need to go with the Headway 38120HP cells. All things considered though, for long range capability and my safety requirements, going Li-Ion with cell level fusing is the only way.
