I don't think any batteries marketed as phosphate last that long, although they may contain lithium phosphate.
The only commercial batteries I know of that can do that are Lithium Titanate/LTO, that you can mostly only buy on AliExpress and a few specialty places, and are almost unheard of in commercial products(Except maybe some wireless earbuds and capacitor-like applications).
They have like 1/4 the energy density or something, but they are still really amazing. I'd love to see power tools use them, we could run tethered on a USB-PD, charging during idle periods, and not wear out from cycling.
- fswd 5y agoYou might be surprised researching the current product offerings. Google "server rack battery". I am off grid with a 5.1kwh server rack lithium phosphate battery. Basically it's all I need. $2200 shipped with accessories, built in BMS with temp sensor and high grade terminals, bluetooth plus RS-485/CANBUS.
- eternityforest 5y agoThose are pretty impressive! I wonder if they have some special software control to only charge up to 90% or something? I've never seem standalone batteries without smart controls go more than 3k for LFP.
