Next, calculate your total daily watt-hour usage. For instance, if you use four LED lights (8 watts each for 5 hours), your daily consumption for lights would be 160 watt-hours. Adding a refrigerator operating at an average of 100 watts for 12 hours gives you 1,200 watt-hours. Therefore, your total daily consumption would be 1,360 watt-hours.

After estimating daily consumption, consider the depth of discharge for your battery type. Lead-acid batteries should not be discharged below 50%. Lithium batteries can be discharged to about 20% safely. This affects the required battery capacity:

• For a lead-acid battery that can only use 50% of its total capacity, if your total daily consumption is 1,360 watt-hours, divide that by 0.5. This yields 2,720 watt-hours as the necessary battery capacity.
• For a lithium battery, use the same daily consumption figure and divide by 0.8 for the usable capacity, resulting in 1,700 watt-hours.

Finally, determine your desired autonomy. Assess how long you want to be off-grid without recharging. If you aim for three days of power autonomy, multiply your daily consumption by three. For a lead-acid system, you would multiply 2,720 watt-hours by three for a total of 8,160 watt-hours, indicating a significant battery capacity requirement. In contrast, a lithium battery would require 5,100 watt-hours (1,700 watt-hours multiplied by three) for the same autonomy.

By evaluating these factors—daily power consumption, discharge rates, battery type, and desired autonomy—you can accurately determine the right leisure battery capacity for your campervan setup.
