Notes about the table
We used only the manufacturer-provided figures. For charging parameters and certain operating behaviors, we recommend consulting the official manual or supplier since some values (e.g., recommended charge current or warranty) are model-specific and may be updated.
Safety and BMS functionality
We like that safety is built into both batteries via an intelligent BMS and recognized certifications.
- Each battery has its own Smart BMS, which handles critical protections like overcharge, deep discharge, high temperature, and short circuit. This minimizes the risk of irreversible cell damage and increases reliability.
- Active and passive cell balancing keeps each cell at a uniform voltage, which helps us get consistent performance over thousands of cycles.
- CE and UN38.3 certifications give us confidence that the batteries meet regulatory and transport safety requirements. For vehicle and marine use, these certifications matter for legal compliance and shipping.
What the BMS means for everyday use
Because the batteries include a smart BMS, we don’t need to add an external BMS in most single-battery installations. When using sets in series or parallel, we must follow the manufacturer’s guidance on configuration, and it’s best to use identical batteries with the same state-of-charge when tying them together. Bluetooth monitoring via the Supervolt app also helps us see state-of-charge, voltage, current, temperature, and any alerts in real time.
Performance and cycle life
This is where LiFePO4 really changes the game compared with lead-acid.
- The A-grade EVE prismatic cells and cell balancing claim more than 3,000 cycles at 90% depth of discharge. That means if we discharge to 10% state-of-charge and recharge daily, we could have many years of useful life.
- The advertised 100% usable capacity per battery is a major advantage over lead-acid, where we typically restrict usable capacity to about 50% to avoid shortening battery life. Practically, two 180 Ah batteries in parallel give us 360 Ah usable at 12 V without the weight penalty of lead-acid.
Practical impact of cycle life on total cost
When we factor in higher usable capacity and longer cycle life, the total cost of ownership for LiFePO4 tends to be much lower over several years compared with lead-acid. We get more usable energy per kg and a much longer lifespan, which matters especially for frequent campers and marine users.
Cold-weather operation and built-in heater
One standout feature is the integrated heater, rated to allow operation down to -30 °C.
- The heater ensures the battery can deliver full performance at very low ambient temperatures by maintaining cell temperature within a safe operating window during charging and discharging.
- This makes the pack suitable for cold-climate travel, winter camping, or boat installations in cold regions where typical Li-ion cells could be limited or damaged without thermal management.
Practical tips for cold use
We recommend wiring the heater control per the manufacturer instructions so the heater engages when needed and does not draw unnecessary power when the battery is already warm. For vehicles, a proper installation that uses battery temperature sensing with chargers and alternators helps ensure safe charging in sub-zero conditions.
Electrical performance: currents, inverter sizing, and load handling
The set promises a constant 200 A discharge per battery? The specification states a constant discharge current of 200 A — likely per set or per battery depending on configuration. Regardless, the set can support heavy loads.
- With a continuous discharge of 200 A per battery, at 12 V that equates to about 2.4 kW per battery; for a pair in parallel we can support higher continuous output suitable for running inverters, fridges, and multiple devices simultaneously.
- Peak currents up to 300 A allow for high transient loads such as motor start or inverter surge requirements.
What this means for inverter selection
For inverter sizing, we should calculate continuous power needs plus peak surge. A quality 3 kW pure sine inverter would be a reasonable match for many uses, and a 5 kW inverter might be supported briefly for surge loads depending on the installation. We recommend sizing the inverter to steady-state loads and ensuring cabling and fusing are appropriate for the battery’s discharge capability.
Installation, form factor, and weight benefits
The compact DIN form (353 × 175 × 190 mm) and weight of 15.5 kg each make installation straightforward.
- The DIN dimensions mean the batteries will fit under most RV seats and in many battery compartments where lead-acid blocks were installed, making retrofits simpler.
- At roughly half the weight of equivalent lead-acid batteries, handling is easier and vehicle payload improves.
Practical installation notes
We advise using proper cable sizes for the rated currents, secure mechanical mounting to prevent vibration damage, and ensuring good ventilation if the battery compartment is enclosed. The M8 terminals and RJ45 ports provide flexible connectivity, and the three RJ45 ports with on/off/reset functionality allow system integration and remote control/reset options.
Compatibility with vehicle and marine systems
Compatibility is broad, but we still need to configure systems correctly.
- The batteries list compatibility with Victron GX systems, MBAC, Truma iNet X, NMEA 2000, CI-Bus, and common solar charge controllers and alternators. That means in most modern installations they will integrate nicely with existing monitoring and control ecosystems.
- For alternator charging and DC-DC chargers, we should select a LiFePO4 charging profile or a dedicated LiFePO4-compatible DC-DC charger to avoid improper charging profiles that could reduce battery life or trigger BMS protection.
Special note for VW Grand California users
The manufacturer recommends the Supervolt Ultra series for VW Grand California due to waterproofing specifics for that vehicle. If we have a Grand California, we should contact the supplier or choose the recommended series.
Charging considerations and recommended settings
Because the pack includes a smart BMS, charging is safer, but correct charging profiles still matter.
- Use LiFePO4 charge profiles for any chargers, inverters with built-in chargers, or alternator/booster settings. This typically involves a higher absorption voltage than lead-acid and minimal to no float, but exact values can vary by battery model.
- For alternator charging, use a DC-DC charger or a LiFePO4-capable charge regulator to prevent the alternator’s voltage-sensing behavior from confusing the BMS. Many vehicles require a dedicated charging profile to reach full state-of-charge safely.
Typical charging advice (general guidance)
We recommend checking the battery manual for exact voltages, but typical practical guidelines are:
- Bulk/absorption voltage around 14.2–14.6 V for 12 V LiFePO4 (confirm with manual).
- Float is often not necessary; if a float is used, set it below maximum charge voltage and according to manufacturer guidance.
- Limit charging current to the manufacturer’s max charge rate; when in doubt, choose a conservative charge current (e.g., 0.2–0.5 C) unless the manufacturer specifies higher fast-charge capability.
Series and parallel configurations
These batteries can be used in series or parallel, giving us flexibility.
- Parallel: Combine batteries to increase capacity at 12 V (e.g., two 180 Ah batteries in parallel yield ~360 Ah usable at 12 V).
- Series: Combine batteries to increase system voltage (e.g., two in series for a 24 V system), and the product supports up to 4 batteries in series for a 48 V configuration.
Important safety notes for multi-battery setups
We must use identical batteries, ideally from the same batch, and ensure equal state-of-charge before connecting in series or parallel. For series connections, regular balancing and monitoring via the Supervolt app helps prevent imbalance. Always follow the manufacturer’s instructions for wiring and fusing to maintain safety and warranty.
Waterproofing and vibration resistance
The batteries are described as waterproof and vibration-proof, which is important for marine and mobile use.
- Waterproofing reduces corrosion risk and makes the pack suitable for boats and exposed installations.
- Vibration resistance improves reliability in vehicles and boats where movement is constant.
What to check during installation
Even with waterproofing, we recommend placing batteries in a location that minimizes direct spray and allows for inspection. Use secure mounting and anti-vibration measures when possible, and ensure electrical connections are tight and corrosion-protected.
App and monitoring features
Bluetooth 5.0 connectivity and the Supervolt app allow convenient monitoring.
- We can see state-of-charge, voltage, current, temperature, and error codes in real time from our phones or tablets.
- Remote monitoring helps diagnose issues early and manage charging and discharging behaviors to maximize battery life.
How we’d use the app
We would check the app to confirm the batteries are balancing correctly after installation, to monitor temperature during cold-weather operation, and to log cycles and charge events for maintenance planning.
