Best LiFePO4 RV Batteries for Full-Time Living & Boondocking (2025)
Reliable RV battery power transforms boondocking from anxious rationing to genuine freedom. LiFePO4 batteries outlast lead-acid by 8-10 years, weigh half as much, and deliver twice the usable capacity—critical advantages for RV life.
The investment ranges from $178 for weekend camping to $437 for full-time living. Redodo backs everything with 5-year warranties and Grade-A automotive cells. These aren’t disposable—they’re decade-long investments in RV independence.
This guide reviews 5 Redodo LiFePO4 RV batteries from weekend warriors to full-timers, matching capacity to real-world needs without the technical overwhelm.
Buyer’s Guide: What RVers Need to Know
Why LiFePO4 Beats Lead-Acid for RVs
The numbers that matter:
- Lifespan: LiFePO4 lasts 4,000+ cycles vs lead-acid’s 300-500 (10x longer)
- Usable power: 100Ah LiFePO4 = 200Ah lead-acid (lead-acid only safely uses 50%)
- Weight: LiFePO4 weighs 60% less (better towing, more cargo capacity)
- Maintenance: Zero vs constant water refills and terminal cleaning
Bottom line: One LiFePO4 battery replaces multiple lead-acid batteries, lasts a decade, weighs half as much, and requires zero maintenance.
Sizing Your RV Battery Bank
Weekend camping (1-2 people): 100Ah handles lights, water pump, 12V fridge, phone charging
Extended boondocking (2-4 people, week+): 200-300Ah powers fridge, lights, electronics, occasional microwave
Full-time living: 400Ah+ runs all appliances including AC units with proper inverter
Quick formula: Your daily power use × 2 (for cloudy days) = minimum battery capacity needed
Group 24 vs Group 31 Sizing
Group 24: 25% smaller, perfect for travel trailers and tight RV compartments
Group 31: Standard RV size, fits Class A/C motorhomes and fifth wheels
Both deliver same power—only physical size differs. Measure your RV battery compartment before ordering.
Bluetooth Monitoring Worth It?
Optional but valuable for RVers. Check exact remaining capacity from inside your RV instead of nighttime walks to the battery compartment. Eliminates boondocking guesswork. Worth the $50 premium for peace of mind.

FAQ
Q: Can I mix different Redodo models in my RV?
No. Batteries in series/parallel must be identical—same model, capacity, BMS, purchased within one month. Mixing causes voltage imbalances and shortened lifespan.
Q: How long do these last?
4,000-15,000 cycles depending on use. For typical RV use, expect 10-15 years. The 5-year warranty backs this.
Q: Can these be RV starter batteries?
No. These are house batteries only. Starter motors trigger BMS protection and cause damage over time. Use dedicated starter batteries for RV engines.
Q: Do I need Bluetooth?
Not essential but valuable. Eliminates nighttime walks to check battery—know exact remaining capacity from inside your RV. Worth $50 premium for boondocking peace of mind.
Q: What about winter camping?
Standard models won’t charge below 32°F (protects cells). Bluetooth models have low-temp protection. For serious winter RVing, consider self-heating models or bring battery inside temporarily.
Pair your Redodo RV batteries with portable solar panels for complete off-grid camping freedom.
