The winston cells are LiFeYPO4 (A different chemistry). Supposedly it improves the temperature performance of the cells. From their website:

"Winston incorporate Yttrium to enhance the cell temperature flexibility as well as performance overall. "

I have an email out to them asking for more details on their cold temperature limits for Discharge, Charge and Storage. I'll post it here if I get any response.
What I have read on the Y cells is deeper cold discharge but no charging change...

Thanks Johan that helps me lots. Im just deciding which group to buy them off now. There are some on ebay here in OZ but they are a little dearer than Aliexpress.
