Reading on LFP cold cut off I see Expert Power has 23F as there cut off on there batteries and I thought it was 32F? Expert Power wrote: Question: Do these have low temperature protection. Will t...

Previously, Trillium info was to limit charging amps on a sliding scale from just under freezing to well above freezing, but their data sheet now shows full 110amp charging right from freezing on up, and reduced charging amps below freezing to a lower temp than before.
No idea if anything new with the LFPs that take heat from a charger before allowing charging, but it was 5C/40F before they allowed charging to start.
I kept asking on here about what to charge at between freezing and 5C and how you could throttle the amps of your charger to do that, but got nowhere. Seems Trillium has changed their story lately. if true for all LFPs now, it is moot.
Perhaps there has been more experience /data with LFPs or they have changed the formula a bit for making the cells, not a clue.
Lesson is to keep up with the latest on all this, because what you learned last year might now be wrong. Eg I see Trillium has "retired" the Trillium Owners Guide, but do have the new charging guide in the Data Sheet
