All LFPs are Lithium-ion, but not all Lithium-ions are LFP.
Wiki article says of "Lithium-ions" that:
" At temperatures from 0 to 5 °C charging is possible, but the charge current should be reduced"
using the same 41F marker that Trillium does.
The questions:
1. Does that apply to all Lithium-ions including LFPs?
2. Is a Trillium an LFP?
Besides all that, worth noting that Lithium-ion development is still on-going with possible associated cost reductions in making them, which should lower their future retail prices if successful.
