if your concern is keeping your family fed, consider the last time you had an extended outage. then run the numbers
if it was recent, such as living in certain parts of texas, you should be keeping large amounts of stable water for each person for at least a week (gallon jugs + water filter pens), fuel/burner/pot, rice/beans/etc in a water sealed emergency kit
if it was a long time ago, you should be keeping enough water, vitamins, and high density calorie bricks for 96 hours
it'd be nice to have fresh food, but it's way more practical and reliable to have sustenance stored in a closet somewhere
for a family of four, premade emergency kits for 7 days will run you about $150, and youll need about 25 gallons of water - <$25
$175 or a $1000 battery + $25 for water. idk choice is easy
