Lithium Titanium Oxide. The specs are insane. 6 minutes to charge 80%, Tolerate -30C, Don't mind being stored full. 5C continuous. $18 for a 20Ah cell. Never cycled. batteryhookup, if you're up for building a battery.

Those are normally open and draw 1.7 watts to stay closed. Definitely want NC. There's this by the same manufacturer, but it's $17700 ! I think an SSR: https://www.aliexpress.com/store/1101444462/search?origin=y&SearchText=ssr+dd, but I'm ignorant. (I had a friend put an SSR in his electric...

https://news.mit.edu/2022/controlling-dendrities-lithium-batteries-1118 It seems the dendrites grow into gaps rather than it being strictly an electrochemical process. Compression closes the gaps, so be sure to compress the batteries in the right direction, into the sides, not pressing the...

I'm new to the LiFePO4 scene so please be kind. A common theme is that the batteries are great and cheap but the supporting electronics will break the bank. I was hoping to use as much of the legacy equipment in my mid 90's Pace Arrow motorhome. To that end I've been scouring the manuals to...

What do you think about using the high current Headway cells for a LiFePO4 starter battery? https://batteryhookup.com/products/12v-handle-beast-module-with-24-headway-38120hp. (I think you still need a small AGM to protect against an alternator surge if the BMS shuts off, so still not acid-free.)
