Which is more or less what I paid for a group31 LiFePo battery... When I really shopped it (industrial sources) I was pleasantly surprised at the price.
Whether it's of benefit really depends on your use as Randy stated. When I first bought windstar I only daysailed and plugged in every night. The stock system was so adequate for that that I didn't even notice a dead alternator for an entire season. I did finally replace it even though the cost clearly wasn't justified. ;-) My more recent scope was to have multiple consecutive days off the grid so I needed to do *something*. (all well documented along with the arithmetic on the blog) I too thought that LiFePo was cost prohibitive for less than 5 year time horizon, however the lower than expected first cost and utterly carefree electrical system have made them a slam dunk. From memory, vs AGM the cost difference might have been C$400 max. as I worked my way though the project, I had an epiphany as I climbed a ladder with two group 31s in one hand, and had further epiphanies when I managed to fit ALL my new batteries and battery management hardware in a much smaller footprint than previously, while simultaneously doubling my usable house bank capacity. I was also surprised at how quickly they charge. After one season with solar/lithium I have enough confidence in the system that when I renew my marina contract next year, I will decline the need for shore power and will save C$400/season as a bonus. To be clear, my enthusiasm is as much about a successful solar install as the LiFePo batteries themselves.
