So far, The Epoch batteries have been a great addition to my camper. I replaced my 120AH Deep cycle with x2 Epoch 105AH LiPo4 batteries. With my 100w solar panel on the roof, I barely made a dent in the consumption (Never drew down past 5-10%) and the solar panel trickle charged it perfectly. My only complaint is the App. I have 2 batteries in parallel and the App is clunky in that you have to "Find" each" battery (It will not recognize the combined capacity) and if I want to look at each battery, I have to close the app, after looking at 1, to go to the other. OTherwise, it just gets hung up "Searching" the 2nd time. Not the end of the world but could be better for battery management since Epoch highlights the app as a feature. Otherwise, its early on but very happy with the purchase.
