Has anyone upgraded their house battery to LiFePO4?

For those unfamiliar with Lithium Iron Phosphate batteries, they have the following advantages:
- Weighs about 1/3 of lead-acid for the same charge capacity.
- They have very low self discharge rate (will hold a charge for months)
- Can be safely discharged to 10-20% of rated capacity (LA batteries should not be discharged below 50%)
- Can be quickly recharged in about 3 hours
- Does not need to be kept at full charge (can be partially recharged without affecting charge cycle life of battery)
- can endure 1500+ recharge cycles ( may be the last battery you need to buy)
- Very stable and safe to use, but less capacity than the LiIon versions used in cellphones and laptops.

Disadvantages:
- Battery is expensive to buy,(be less expensive after calculating number of recharge cycles and more usable capacity so fewer rated AmpHrs needed)
- Cannot be recharged if battery is below freezing
- Requires a "Smarter" battery charger (converter) for maximum charge cycle life and fastest charging rate.

Just wondering about the experiences of those out there using these batteries now.

Thanks for your input.
