I’ve been looking at upgrading our battery bank, stationary and in temperate climate so most pros and cons don’t apply.
The only one that matters to us is usable Joules per dollar. You’d have to make your own spreadsheet with local pricing but for us assuming 95% usable lifepo and 50% usable agm, agms do come out be be slightly cheaper.
However, since lifepos are expected to last about twice as long we’re going with lifepos as they will be a long term investement.
If you’re only looking short term and planning on taking good care of them agms are still a valid choice.
Economies of scale and subsidies/successful lobbying.
