I have 2 Epoch 12V 100ah heated lithiums for electronics batteries in 2 separate boats. The one is about a year old and has a on off switch on top, the other was purchased in Dec 23 and has been used a bunch since. The newer battery has no on/off switch. Both have been stored and charged in an unheated garage with no problems. May switch trolling batteries when replacing down the road.
