DIY Solar Systems
After using the Ampere Time self heating battery in the shop for 4 weeks I have to say it is doing very well. I use this battery to power my studio lights and outlets in the shop. There have been several below freezing nights during this test and the battery has heated itself up before charging. With 2560wh the battery is able to provide power for a long while. This is a 12v 200ah LifePo4 battery designed for solar and hydro applications.
