Are we looking for a reliable, high-performance battery solution to power our motorhome, van, boat, or off-grid solar set-up?
Quick Overview
We like to begin with a clear snapshot so we immediately know what we’re dealing with. The Pro LiFePO4 2 x 12 V 105 Ah Lithium Batteries Set | 100% Usable Capacity, Plug & Play DIN Dimensions, with Smart BMS, Bluetooth & Heating up to -30 °C | For Motorhome, Box Van, Boat, Solar is a pair of DIN-sized LiFePO4 batteries designed as a drop-in replacement for many lead-acid battery banks. We find that the combination of A-grade EVE prism cells, a smart BMS, Bluetooth monitoring, and an integrated heater makes this set attractive for cold climates and mobile installations.
Key Features
We want to highlight the standout capabilities so we can judge fit for our needs. This section breaks down the main selling points and what they mean in practice.
Safety and Smart BMS
We appreciate safety features because batteries are the heart of any mobile power system and mistakes can be costly. The integrated smart BMS protects against overcharge, deep discharge, overheating, and short circuits, and it provides active and passive cell balancing to keep voltages uniform and extend service life.
We also value certifications: CE and UN38.3 are present, indicating compliance with key safety and transport regulations. Bluetooth 5.0 connectivity lets us monitor both batteries in real time via the Supervolt app, so we can check state of charge, temperature, and fault alerts from our phone.
Capacity and Cycle Life
We want usable capacity and longevity so we don’t replace batteries frequently. Each battery is 12 V 105 Ah, and the vendor claims 100% usable capacity — meaning we can use the full rated amp-hours without damaging the cells in typical operation.
We also note the long life: more than 3,000 charge cycles at 90% depth of discharge using high-quality A-grade EVE prism cells. That contrasts strongly with lead-acid options, which effectively offer far fewer usable cycles and often recommend only 50% depth of discharge.
Power, Cold Performance and Heating
We require reliable power output for simultaneous loads and in cold weather. The set provides a constant discharge current of 160 A (about 2 kW continuous) and peak currents up to 250 A, which is sufficient to run most camping appliances concurrently.
Because cold temperatures reduce lithium performance, these batteries include an integrated heater that allows full performance down to -30 °C. That feature is important for winter camping, high-latitude boating, and off-grid installations where ambient temps can drop well below freezing.
Physical Fit and Installation
We want convenience and minimal modification during installation. Each battery follows DIN dimensions (278 × 175 × 190 mm) and weighs 10.5 kg, roughly half the weight of equivalent lead-acid batteries. That compact, light package fits under most RV seats and simplifies plug-and-play replacement.
We also like the M8 threaded posts, multiple RJ45 ports, and the fact that the batteries can be connected in series (up to 4 for 48 V) or parallel for higher capacity. This makes scaling straightforward for a range of applications.
Compatibility and Connectivity
We need batteries that play nicely with chargers, alternators, and system monitors. The set is compatible with Victron GX, MBAC, Truma iNet X, NMEA 2000, CI-Bus, and standard solar/charging systems. The 3×RJ45 ports support on/off and reset functions as well as system integration, expanding our monitoring and control options.
We should note that for VW Grand California users the manufacturer recommends the Supervolt Ultra series for guaranteed waterproofing in that specific vehicle. We should consider that recommendation when planning an installation in that model.

Performance in Real-World Use
We like to know how these batteries behave under actual conditions since lab specs don’t tell the whole story. Here we cover discharge performance, charging behavior, temperature influence, and practical runtime scenarios.
Continuous and Peak Discharge
We want a battery that supplies steady power without sagging under load. The set reliably provides 160 A continuous, which suits most inverter loads and multiple appliances running together, such as a small 12V compressor fridge, LED lighting, water pump, and electronics.
We also appreciate the 250 A peak capability for handling inrush currents from compressors and some AC inverters. The smart BMS prevents damage during brief peaks, so appliances that demand momentary high current will start reliably.
Charging Behavior and Fast Charging
We prefer batteries that take a full charge quickly when we have shore power, solar, or an alternator available. These LiFePO4 batteries support fast charging and can accept higher charge currents than equivalent lead-acid batteries without harming the cells, provided the charging source is compatible with LiFePO4 charge profiles.
We recommend pairing the batteries with a LiFePO4-capable charger or a DC-DC charger/boost that supports adaptive charging. The Bluetooth app lets us observe charging voltage, current, and state of charge so we can optimize charge sources and timings.
Temperature Performance (Heating System)
We expect diminished performance from lithium batteries at low temperatures unless heating is provided. The integrated heater in this set lets us maintain cell temperature so we can charge and discharge effectively down to -30 °C, which is a significant advantage over many LiFePO4 batteries that can’t safely charge below ~0 °C.
We should note that the heater consumes some power to operate when it’s active; however, the design is intended to preserve functionality in extreme cold and prevent cell damage from charging at sub-zero temperatures.
Runtime Examples
We find concrete runtime examples help us assess whether this set meets daily power needs. With 2 x 12V 105 Ah batteries in parallel (assuming nominal 12 V and 100% usable capacity), our total available energy is roughly 2.52 kWh (12 V × 210 Ah ≈ 2520 Wh).
- Small setup: A compressor fridge (40 W average), LED lights (20 W), phone charging (10 W) = 70 W continuous. Runtime ≈ 36 hours.
- Medium setup: Fridge (40 W), heater fan (150 W intermittently), water pump & lights (50 W) = 240 W average. Runtime ≈ 10–11 hours.
- High load with inverter: 2 kW continuous inverter load is within continuous discharge capacity of the set (approx 160 A at 12 V gives ~1920 W). Runtime at 2 kW ≈ 1.25 hours before recharge needed.
We highlight that these are simplified estimates and real-world runtime will vary with inverter efficiency, battery age, ambient temperature, and simultaneous loads.
Installation and Integration
We like straightforward installs that don’t require extensive modification to our vehicles or boats. This section covers mechanical fit, wiring, and integration tips.
Mechanical Fit and Weight
We want batteries that fit typical battery bays and are easy to handle. Each battery’s DIN dimensions and 10.5 kg weight make them easy to install under most RV seats or in engine compartments where lead-acid batteries previously sat.
We find the lower weight also reduces strain on mounting points and makes swapping or servicing simpler. Always secure batteries well to prevent movement and protect M8 terminals from short circuits.
Electrical Connections and Series/Parallel
We appreciate batteries that are flexible in system design. The set supports parallel connections for increased capacity and series connections (up to four batteries) to create higher voltages for specialized systems.
We recommend using properly rated cables, fuses, and busbars when connecting batteries in series or parallel. Using mismatched batteries or cables with poor connections can lead to imbalance and reduced life; we advise equal-length cabling and professional-grade terminals.
Integration with Victron, Truma, and Other Systems
We want seamless communication with our charge controllers, alternators, and monitoring systems. The Pro LiFePO4 set integrates with Victron GX systems, MBAC, Truma iNet X, NMEA 2000, and CI-Bus, making it possible to use familiar monitoring and control ecosystems.
We should configure the charger and alternator to LiFePO4 profiles where possible and verify that the inverter/charger management system is aware of LiFePO4 behavior. The RJ45 ports provide on/off and reset functions, which we can use to integrate with system automation.
Safety, Certifications, and BMS Details
We prefer batteries that prioritize safety and provide data so we can operate with confidence. This section focuses on the BMS, certifications, and practical safety considerations.
Smart BMS Functions
We value a BMS that actively manages cell health and system safety. The intelligent BMS in this set manages cell balancing, over/under voltage protection, temperature cutoffs, and short-circuit protection. Active and passive cell balancing helps maintain longevity across the pack.
We also find the Bluetooth-linked app helpful; it provides alerts for abnormal conditions and logs data that we can use to assess battery health over time. Firmware updates may be available to improve BMS behavior; check the Supervolt app or manufacturer portal.
Certifications and Transport
We like products that meet regulatory standards for safety and transport. CE and UN38.3 certifications indicate the batteries meet common European safety regulations and transport conditions for lithium batteries.
We recommend checking local regulations for shipping and installation in vehicles or marine craft, especially if integrating multiple batteries to create higher-voltage systems.
Practical Safety Tips
We take a few precautions during installation and use to stay safe. Always disconnect the negative terminal first when working on the battery, use insulated tools, fit appropriately rated fuses and circuit breakers, and avoid exposing terminals to conductive debris.
We also recommend storing batteries partially charged for long-term storage (around 50–70% SOC) and keeping them in a dry, vibration-protected mount.

Troubleshooting and Maintenance
We prefer to know how to handle problems and keep batteries healthy over years of use. Here we outline common issues and steps to resolve them.
Common Issues and Quick Fixes
We sometimes encounter startup faults, unexpected cutoffs, or incorrect state of charge readings. First, check the Supervolt app for any fault codes and BMS warnings. Confirm cable integrity, terminal tightness, and fuse/circuit breaker condition.
We also recommend ensuring chargers and alternators are set to LiFePO4 charging profiles to avoid false cutoffs or improper voltage regulation. If Bluetooth connectivity is lost, move closer to the battery or check for app updates.
Maintaining Battery Health
We pay attention to storage state, temperature, and charge cycles. For long-term storage, keeping the batteries at about 50–70% SOC and in a cool, dry place extends life. Avoid leaving them fully discharged for extended periods and maintain a regular charge schedule when in storage or infrequent use.
We should occasionally observe the balancing behavior and cell voltages through the app. If a battery shows persistent imbalance or drastically reduced capacity, contact the manufacturer for warranty support.
