This thread is way off subject but I have in the past used a 12Ah powered Jump Starter Box, car battery , deep cycle marine battery, Spiral cells AGM sealed deep cycle(48 Ah), two 125 Ah (250 total ) flooded cell deep cycles and another 48Ah Siral cells sealed AGM.
It all depends on what one's needs are. Recently purchased a Hoda 2000 watt Inverter ( generator) and I have power supplies out the
so I will likely stay with the 48Ah sealed AGM for some time as it is enough for a morning at the field and if I go to a distance field for the day that does not have AC then the Hoda can be used. I may even use it at my local field during the hot days of summer so I can have a couple of fans to help keep cool.
