So this is around 20% of that, according to the above. “Excellent” may be in comparison to other byzantine specialty battery chemistries, but lithium ion remains resolutely enthroned.

Weight doesn’t matter at all since the battery won’t be moved. The most important thing is lifetime. Traditional nickel iron batteries last for decades and can be refurbished.
