Frequently Asked Questions
What type of battery is best for RV house use?
Lithium LiFePO4 batteries are generally best for RV house use due to their high cycle life (2000-5000+ cycles), light weight, and ability to discharge deeply without damage. AGM batteries are a good budget-friendly alternative with lower upfront cost but heavier weight and shorter lifespan. Flooded lead-acid batteries are the cheapest but require maintenance and ventilation.
How many amp-hours do I need for my RV?
The required amp-hours depend on your power consumption. A typical RV with lights, water pump, and a small inverter may need 50-100Ah per day. For larger loads like a microwave or air conditioner, 200Ah or more is recommended. We suggest calculating your daily watt-hour usage and dividing by 12V (for a 12V system) to estimate amp-hours needed, then add a buffer of 20-50%.
Can I mix lithium and lead-acid batteries in my RV?
Mixing lithium and lead-acid batteries is not recommended. They have different charging profiles (voltage and current requirements) and the BMS in lithium batteries may conflict with lead-acid chargers. This can lead to overcharging or undercharging, reducing lifespan and safety. If upgrading to lithium, replace all house batteries or use a separate charging system.
Do I need a special charger for lithium RV batteries?
Yes, lithium batteries require a charger or converter that supports their charging profile, typically with a bulk voltage around 14.4-14.6V and a float voltage around 13.6V. Many modern RV converters have a lithium setting, or you can use a dedicated lithium charger. Using a lead-acid charger may not fully charge the battery or could damage it over time.
How long do RV batteries typically last?
Lifespan varies by type and usage. Flooded lead-acid batteries last 3-5 years with proper maintenance. AGM batteries last 4-7 years. Lithium LiFePO4 batteries can last 10-15 years or more, depending on cycle count and depth of discharge. Factors like temperature, charging habits, and discharge depth significantly affect longevity.
