Several observations from someone interested for my camper, and for my ham radio hobby.
1. These are Lithium Iron Nanophosphate which is likely the A123 technology developed for electrical vehicles and probably good
2. Have heard of demos where a nail was shot into a battery pack under load and nothing exciting happened other than losing that cell.
3. For long term life and maximum performance, chargers may need to be able to equalize individual cells. While you may be able to get to 80% charge in 15 minutes (given sufficient solar PV panels, chortle The cells need to be managed differently for the remaining 20%.

4. I would use marine fuses that attach directly to the battery post/connectors as these batteries can dump incredible amounts of amps into a short circuit. (See http://neverded.com/maxx/ or http://antigravityba...com/microstart/ )
