Lead-acid to lithium conversion, BMS troubleshooting, inverter and converter compatibility, and battery monitor install. Most upgrades complete in a single day at your driveway, storage facility, or campsite.
RV lithium battery install from Mobile RV Pro covers full lead-acid to lithium conversions, BMS (battery management system) troubleshooting, converter and inverter compatibility review, and battery monitor installation. Installs happen at your location across Utah and Texas. The conversion is more than dropping a lithium battery in place of lead-acid — converter charge profiles, inverter low-voltage cutoffs, and shore-power charging logic all need verification. Mobile RV Pro handles the full system review so the lithium upgrade delivers the runtime gain it promises. Certified technicians, brand-agnostic battery selection, written estimate before any work begins.
Most lithium problems are not battery problems — they are compatibility problems with the converter, inverter, or alternator charging system that was originally specified for lead-acid. Diagnosing the system before the install prevents these issues.
RV converter set for lead-acid charge profile — typically caps at 13.6V, below lithium full charge. Converter replacement or profile adjustment is the fix.
Battery management system shutoff from over-current, over-temperature, or cell imbalance. Diagnosis requires reading BMS fault codes via Bluetooth or wired interface.
Inverter low-voltage cutoff set for lead-acid (11.5V); lithium runs at higher resting voltage but drops fast at end of discharge. Cutoff needs adjustment for lithium curve.
Standard lithium iron phosphate cannot charge below 32°F — BMS blocks charge to prevent cell damage. Solution is heated battery, low-temp BMS, or cold-weather charging strategy.
Lithium accepts charge faster than lead-acid, pushing alternators beyond design current. DC-DC charger between alternator and battery is the standard fix.
Voltage-based monitors do not work on lithium — voltage curve is too flat. Shunt-based monitor (Victron BMV-712 or SmartShunt) reads actual coulombs in and out.
If you have already installed a lithium battery and are seeing any of the issues above, do not assume the battery is defective. The most common cause of lithium “battery failure” is system compatibility — converter, inverter, alternator, or monitor that was not adjusted during the conversion. Mobile RV Pro can review an existing lithium install and identify the configuration issue without replacing the battery.
Mobile RV Pro is brand-agnostic on lithium — selection is driven by your runtime needs, RV electrical capacity, and budget. Common brands installed include Battle Born, Renogy, LiTime, Lion Energy, Victron, Dakota Lithium, and Epoch.
Lithium pricing varies widely by battery brand and bank size. Mobile RV Pro will quote brand-agnostic options at three price tiers so you can choose. Ranges below are all-in for labor and supporting components — battery cost is quoted separately so you can compare brands. Diagnostic, labor, and supporting parts at typical cost.
| Repair Type | Typical Labor Range | Notes |
|---|---|---|
| Single 100Ah lithium install (labor + supporting parts) | $580 – $1,100 | Battery quoted separately; converter check included |
| Full lead-to-lithium conversion (200–400Ah bank) | $1,800 – $4,200 | Includes converter swap, monitor install, BMS verification |
| Premium build (400–600Ah with inverter upgrade) | $3,500 – $7,500 | Full off-grid capable system |
| DC-DC charger install | $520 – $980 | Protects alternator, required for towed or motorhome |
| Lithium-profile converter swap | $520 – $920 | Critical for full lithium charging |
| Battery monitor install (Victron BMV-712 or SmartShunt) | $320 – $580 | Only accurate state-of-charge for lithium |
| BMS troubleshoot or existing lithium review | $280 – $580 | Diagnose existing lithium install without parts |
| Diagnostic only (no install) | $270 – $360 | Walk-away price if you decline work |
Mobile RV Pro provides a written estimate before any work begins. We quote battery brand options at three price tiers so you can choose — same labor cost regardless of which battery you pick. Combined Solar + Lithium installs are quoted as a single project.
Mobile RV Pro technicians are certified, background-checked, and carry full liability insurance. The company is licensed and insured to perform RV repair across Utah and Texas. If a technician damages any component while performing a hired repair, Mobile RV Pro covers the replacement 100% — both parts and labor.
Mobile RV Pro is an authorized warranty coordinator for most major extended warranty providers including Good Sam, Wholesale Warranties, Cornerstone, and National General. We coordinate repairs and payment directly with extended warranty companies on your behalf — at no extra charge.
Most lithium "failures" are system compatibility issues — converter not configured for lithium, inverter cutoff set for lead-acid, alternator overheating from faster lithium charge acceptance. Mobile RV Pro reviews the full charging and discharging system before every install: converter profile, inverter cutoff, alternator load, monitor calibration. The lithium upgrade only delivers its full benefit when the rest of the system is adjusted to match.
Certified technicians dispatched to your location — driveway, storage facility, or campsite. No haul-in, no storage fees.
Lithium conversions at dealerships often skip the supporting-system review and just drop the battery in. The result is the lithium "performance gap" customers report — runtime is up, but full charge is never reached. Mobile RV Pro reviews the full system as part of every install.

| Battery brand selection | Brand-agnostic, three price tiers | Single OEM option |
| Converter swap if needed | Quoted in same project | Separate work order |
| Battery monitor install | Standard recommendation | Rarely included |
| Install location | Your driveway | Dealer lot |
| Written estimate | Always before work | Package pricing |
