[QUOTE="hispls, post: 8658803, member: 614752"] Like I said, if those cells are 30C rated even if someone was getting max power out of that amp for prolonged periods of time those cells shouldn't be terribly over-stressed, bigger stress would be on the charging side if you have an HO alternator! LiFePO4 cells are 2000-3000 cycles rated so I'd expect barring getting a dud cell in the bank or gross abuse they're not paying out too many warranties assuming they do 1 year. I wouldn't say overpriced. I priced the A123 cells (which some of these guys use or at least used at one point) and after bussing, a case, labor, and eating a few warranties they're priced about what you'd need to price them at to keep the lights on and make a living. I'm confident that LiFePO4 technology is very safe and it would be nearly impossible to have them fail in a way that is dangerous. Biggest risk is that a dud cell slags the capacity of all cells in the bank. If you're in Texas you definitely won't have to worry about loss of performance from being too cold. By all accounts LTO holds up very well down to freezing and even a good bit beyond that. Even the guys in know in Massachusetts who ran LiFePO4 last winter had no complaints and LiFePO4 is known to be quite weak at and below freezing. Definitely do NOT put these under the hood. They've got pretty good tolerance on the hot side, but keep an eye on that if you run them hard and live where it's 110 degrees most of the year.... perhaps an open side bank or some fans? Though if you're going 4p6s You'll barely be pushing 1C in or out 90% of the time. I'd also like to thank Shizzon who did post some useful explanations and info in a previous lithium thread... he never got back to me when I emailed him about buying cells though. [/QUOTE]
