LiFePO4 battery or SLA lead battery: Which battery is suitable for my ARI Motors electric vehicle?

With the electric transporter ARI 458 as well as the passenger vehicles, you have the choice between the standard SLA lead battery and the optionally available LiFePO4 batteries in different versions. The SLA batteries have the advantage that they are maintenance-free, robust and inexpensive. However, they are also very heavy with approximitely 200 kg. The LiFePO4 batteries, on the other hand, are significantly lighter at around 90 kg, which can increase the payload. If payload is critical to your transportation needs, you should consider the LiFePO4 battery.

LiFePO4 batteries are also more powerful, which means that longer ranges of up to 495 km are possible with the ARI 458. While the SLA lead battery has a capacity of 120 Ah and the vehicle can travel around 120 kilometers, the three variants of the LiFePO4 battery have capacities of 160 Ah, 205 Ah and 275 Ah for ranges of 150, 200 or 250 kilometers. Since all batteries can also be installed twice, double the range is optionally possible here. If higher ranges are important for your requirements, you should opt for a LiFePO4 battery.

In addition, LiFePO4 batteries have a longer shelf life: while lead batteries have a service life of 900 – 1.000 charging cycles, LiFePO4 batteries have more than 5.000. This means that the additional costs when buying (e.g. 2,600 euros for the LiFePO4 battery with 150 km (93 mi.) range) or replacing (SLA: 1,600 euros, LiFePO4: from 2,600 euros) the battery can be offset in the long term. The guarantee period is 4 years or 60,000 kilometers longer, while SLA batteries have a 6 month guarantee followed by an 18 month guarantee. Consequently, if you are planning on using the vehicle very frequently and therefore also performing a lot of charging processes, the LiFePO4 battery is also more preferable here.


If you or your company have high requirements in terms of payload, range and driving performance, the LiFePO4 battery is the better choice thanks to its lower weight, greater range and greater durability. In addition, it represents the latest and most modern technology in the field of electromobility. The standard SLA lead battery is particularly convincing due to its low cost to purchase. It is especially suitable for customers with low transport volumes and manageable ranges, who also appreciate a very economical solution for their transport tasks.
