China Sourcing

• $32 for 100Wh - 80Ah bat cells- [9]
• This means 4kW would be $1280, causing an energy transition to off grid.
• 800Ah - weighs 57 kg. [10]
• 1200Ah for $200 each? [11]. That would be $140/kw, unreal. Table says 62kg filled. If weight in nickel is 1/5, that is only 12kg nickel. So the price would be $120 in materials. They are selling at $140.

Other from China Sourcing

• http://www.beutilityfree.com/index.php/products/nickel-iron-batteries/nickel-iron-testimonials - from thread at [12] which estimates that a 1800Whr system has $600 of nickel in it. Good thread - says these batteries really work and are robust. You can replace cells easily, not like with lead acid.
• IronEdison
• Zappworks -
• Australia - Ironcore - [13]

Notes

• Nickel-Iron Battery/Sourcing - more info on nickel hydrate
• Nickel is 20% of the battery - [14]
• If nickel is 1/5 the battery, and nickel is $6/lb raw - then price of battery is $1/lb based on nickel cost. Thus a 50 kg battery should be $100 in materials only. If nickel hydrate was obtained readily from nickel.
