Are lithium batteries worth the cost?

Have you used it in cool/cold weather yet?

Just our local weather with highs in the 40-50's when I ran my fridge for 11 days off it..I charged it up to 70% when I was done playing with the Engel fridge and haven't used it since because plans keep getting changed for my fishing trip..LOL..

But I must ad,I keep it inside my TC,not in the battery compartment provided so weather is not a concern to me..While using or discharging them in cooler weather is not a problem,it is the charging that is the problem below 32ish..

My last two batteries I bought off line came with several foam exterior protectors for the battery that would make a great insulator for colder weather and making an opening to the battery compartment for inside heat circulation...

For every issue there is a fix...LOL
