So the Battleborn batteries are 100Amp-hour capacity.
This means that they can supply 100 Amps for an hour. With 6 batteries they can supply 600 Amps DC for an hour.
There are a couple of advantages for lithium batteries. They don’t mind how you use the amps. You can pull all 600 amps quickly or over a longer period of time. With lead-acid batteries there is a penalty for pulling the amps too quickly, you will not get the rated amp-hour of the battery. Also, lead-acid batteries will be damaged if you EVER pull more than 50% of their charge.
Richard says batteries never die, they are murdered. This is the reason...if you pull your batteries below a 50% charge, you are eating into their expected life.
So...in my case, I went to bed at 11:00pm with fully charged batteries and a worst case 25amp draw. I woke up at 6:30. That is 7.5 hours x 25 amps = 187.5 amp hours. So, overnight with no particular power conservation I used 31% of my capacity. If I turned off a few things, the current draw would be 13 amps -> 16% capacity used overnight.
Food for thought.
