Lithium heating pads
Has anyone added heat pads to your lithium batteries so you can charge below freezing. If you did what did you use and how did it work

Here is the heater I purchased from Amazon (it's more $$ in Canada): Link
It goes on automatically at roughly 7C and shuts off at 20C.
Attached it to some stock sheet aluminum to spread the heat across all 6 batteries. Added a cut-off switch for when I don't need it.
Also use a Victron temperature sensor connected to my Victron MPPTs to ensure that the solar won't charge the batteries is they go below 5C.
