150Ah lithium battery for motorhomes – tested
This time we've selected four batteries from four different brands. These brands are quite popular in the lithium battery market, and many users are eager to see how they perform in practice. So join us for our test and let's find out together.
LiTime 12V 140Ah: LiTime is a brand that prioritizes value for money as its key selling point and has a deep understanding of user needs. While the LiTime 140Ah battery tested here doesn't have the nominal capacity of 150Ah, it is specifically designed for use in motorhomes – which is why we included it in our test series.
Supervolt 150Ah 12.8V: Supervolt is a battery brand based in southern Germany, specializing in the development of high-quality LiFePO₄ batteries. Their products are primarily used in motorhomes, campervans, and off-grid energy storage systems. They are priced in the premium segment.
Liontron 12V 150Ah: Liontron is a German brand specializing in LiFePO₄ (lithium iron phosphate) batteries. Their products are manufactured using a modular design and have received the European Innovation Award for sustainability. The average selling price is also in the higher range.
Eco-Worthy 12V 150Ah: Eco-Worthy is a Chinese brand specializing in solar and energy storage solutions, with nearly twenty years of experience. The company offers a wide range of products, focusing on off-grid and solar power systems. Pricing is primarily geared towards providing excellent value for money.
Capacity – Does the battery really deliver 150Ah?
We fully discharged each battery using professional discharge equipment under a constant 25 A load to determine the actual usable capacity. All four batteries tested reached or slightly exceeded their nominal capacity. Eco-Worthy A capacity of 161 Ah The Liontron battery lived up to its reputation for "positively tolerated cells" with a result of nearly 160 Ah. The Supervolt achieved 153.3 Ah, also exceeding its nominal value of 150 Ah. While the LiTime battery had a lower capacity than the other three models, it still reached exactly the specified value. Even in the high-load test with a continuous discharge of 1500 W, each battery demonstrated stable performance.
Cell type – prismatic or cylindrical?
In the field of lithium batteries for motorhomes, the design of the battery cells is a crucial factor for performance, dimensions, and lifespan. Prismatic cells are characterized by efficient space utilization, ease of installation, and simple maintenance, and have therefore established themselves as the preferred choice for high-quality, large-capacity LiFePO₄ batteries. Cylindrical cells, on the other hand, require the parallel connection of many small individual cells, which makes the design more complex. All four tested products agree on this point: they all rely on prismatic cells, which allow for better space utilization and are easier to install. This corresponds to the current high standard in the market for specialized lithium batteries for motorhomes. It is worth noting that LiTime A+ or EV-grade cells used, which generally stand for higher quality and consistency standards.
Constant discharge current – How efficient is the battery during operation?
This aspect lies Supervolt With its powerful 200A BMS, it is clearly ahead. This enables a continuous power output of around 2560 W. This provides users with a large power reserve, allowing several high-power devices to be operated simultaneously.
- LiTime (150 A) & Liontron (150 A): Both batteries are equipped with a 150A BMS, which enables a continuous power output of approximately 1920 W.This corresponds to a high-performance and practical industry standard that is more than sufficient for most motorhomes. It allows for the easy operation of 2000W class inverters – a balanced ratio between performance and practicality.
- Eco-Worthy: There are different versions available. The 120 A version achieves a continuous output of approximately 1536 W, which is sufficient for everyday use, but may reach its limits when operating devices with high power consumption. Therefore, it is advisable to choose a version with a higher BMS capacity when purchasing.
Weight – Which battery is lighter for travel?
To enable a fairer comparison, we consider not only the absolute weight but also an important metric – the energy density (Wh/kg). This value indicates how much energy can be stored per kilogram. For clarity, we present the results in a table:
| battery | LiTime | Eco-Worthy | Supervolt | Liontron |
|---|---|---|---|---|
| Energy density | ~138 Wh/kg | ~122 Wh/kg | ~122 Wh/kg | ~91 Wh/kg |
LiTime It is the lightest battery in the comparison. Although its capacity is 140 Ah, it impresses with its very low weight and achieves the highest energy density.
Size – Does the battery fit well in the motorhome?
In European motorhomes, especially in the most common models like the Fiat Ducato and its sister models, the battery compartment under the driver's or passenger's seat is the ideal installation location. This area typically adheres to a standard dimension, DIN H8 (or L5), the main limitation of which is a maximum height of 190 mm. Whether a battery "fits" therefore depends largely on whether it meets this height requirement.
The batteries of LiTime and Supervolt With a height of 189–190 mm each, they fall within this specification. This means that they are considered "Drop-in Replacement" They can be easily installed in the battery compartment under the seats of most European motorhomes without requiring any modifications to the vehicle. This is a major advantage for users who value easy installation.
The Eco-Worthy and Liontron batteries, on the other hand, are taller. Buyers should therefore carefully plan a suitable, sufficiently high installation location and take precise measurements before purchasing.
Certification – Which models meet international standards?
In the area of safety and compliance, LiTime Supervolt boasts the most comprehensive certification list. In addition to basic certifications, the brand holds an IP65 water resistance rating and the highly stringent UL-1973 safety standard, which enjoys a high reputation worldwide. For physical protection, Supervolt and Liontron impress with their high-quality IP67 water resistance. Furthermore, Supervolt has ECE-R10 approval, ensuring safety in vehicle operation.
