[QUOTE="hispls, post: 8823900, member: 614752"] I was about the first person in the USA to get into LTO cells. At the time we did this the only other people who were using those for car audio was a team in Russia. [URL unfurl="true"]https://www.caraudio.com/threads/lithium-titanate-lto-battery-bank-build.600099/[/URL] So far so good, these are still performing admirably. I did a lot of research on this because none of the car audio "brands" would give me straight answers but only sales pitches. Currently I do have some YingLong 40AH cells and some Toshiba 10AH cells. I do not think anybody is doing ready made banks for the Toshiba cells but YingLong 40 has become very popular so off-the-shelf options for busing are easy to come by. Without a well kitted out metal shop you'll definitely struggle building your own bus bars.
