How to Choose a Battery Backup for Boondocking
1. Prioritize capacity. Weekend trips need 700–1000Wh. Full‑time boondocking needs 1500–3000Wh+.
2. Choose LiFePO4 batteries. They last 5–10x longer and handle heat better.
3. Look for fast solar input. 400–1000W solar keeps you powered indefinitely.
4. Check output wattage. 1500–2400W runs most RV appliances.
5. Consider expandability. Add‑on batteries extend runtime without replacing your system.
