6. Determining Your Power Needs
Before choosing a battery, it’s essential to calculate your power needs to ensure you select a battery with sufficient capacity.
6.1. Listing Your Appliances and Devices
Start by listing all the appliances and devices you plan to use in your travel trailer, along with their power consumption in watts.
| Appliance/Device | Power Consumption (Watts) | Usage (Hours/Day) |
|---|---|---|
| Refrigerator | 150 | 24 |
| Lights | 30 | 6 |
| Water Pump | 60 | 1 |
| Phone Charger | 10 | 4 |
| Laptop | 50 | 2 |
| TV | 80 | 3 |
6.2. Calculating Total Power Consumption
Calculate the total power consumption for each appliance by multiplying its power consumption in watts by the number of hours it will be used per day.
| Appliance/Device | Power Consumption (Watts) | Usage (Hours/Day) | Total Watt-Hours/Day |
|---|---|---|---|
| Refrigerator | 150 | 24 | 3600 |
| Lights | 30 | 6 | 180 |
| Water Pump | 60 | 1 | 60 |
| Phone Charger | 10 | 4 | 40 |
| Laptop | 50 | 2 | 100 |
| TV | 80 | 3 | 240 |
| Total | 4220 |
6.3. Converting Watt-Hours to Amp-Hours
Convert the total watt-hours per day to amp-hours (Ah) by dividing by the battery voltage (typically 12V).
Total Amp-Hours/Day = Total Watt-Hours/Day / Battery Voltage
Total Amp-Hours/Day = 4220 / 12 = 351.67 Ah
6.4. Factoring in Depth of Discharge
To determine the battery capacity you need, factor in the depth of discharge (DoD) for the battery type you plan to use.
- Lead-Acid: 50% DoD
- AGM: 80% DoD
- Lithium: 90%+ DoD
For example, if you choose AGM batteries with an 80% DoD:
Required Battery Capacity = Total Amp-Hours/Day / DoD
Required Battery Capacity = 351.67 / 0.80 = 439.59 Ah
Therefore, you would need approximately 440 Ah of AGM battery capacity to meet your daily power needs.
