I looked into Nickel Iron. No US manufacturers because of patent issues, but they have other issues. They bleed off with no connected load, their charge per weight is much lower than LiPO, and how do you find a charger that works well with them? I loved the idea, and even thought it would be cool to make a bolt on keel that was basically a giant Nickel Iron battery. Imagine filling the electrolyte (which is lye I think?) through a plugged hole in the bilge :)

I have used NIMH without a BMS and they seem to work quite well too.Unfortunately there are no large size NIMH batteries available because of patent issues.
