[QUOTE="hispls, post: 8766957, member: 614752"] That's not even a bad price for those cells these days what with demand for them plus shipping rate increases. The difference is, those YingLong cells are good for 5C charge and 10C discharge, or on 40AH bank 200A charge and 400A discharge. LTO are also meant to last 20 years and that 40AH bank would be the size of a 6 pack of 16oz cans and weigh in at about 15 pounds. They can be had for a bit less money than the XS Power branded ones if you care to shop around and/or DIY bus bars. That all said, I think most folks are under-sizing their banks of those and not really looking at the long term value of keeping them 5C discharge max and planning to own them for 20 years. Dollar for dollar, even at XS Power branded price these will outperform AMG by every measure and outlast them by multiples. Notable new amps right now is Sundown (and a handful of other brands) selling Chinese made Soundigital knockoffs. They're about what you expect as far as sound, performance, and build quality, but Sundown flavor comes with Sundown warranty and all of them are priced at around Taramps price per watt. Well worth considering. In the 3K department specifically I think Taramps SMART3 would be tough to beat in bang for buck. [/QUOTE]
