The lithium battery Polar 320 Ah for underseat installation in the Fiat Ducato is a powerful, space-saving and modern energy solution for demanding motorhomes. Thanks to LiFePO₄ technology, you benefit from high efficiency, a long service life and reliable performance – even under challenging conditions.
With a capacity of 320 Ah, this lithium battery easily replaces conventional GEL or AGM batteries with up to 640 Ah. At the same time, it impresses with a significantly lower weight and a compact design specially suited for installation under the seat in the Fiat Ducato. A horizontal installation is also possible.
The integrated 10 A heater ensures that the battery operates reliably even at temperatures as low as -30 °C. Combined with the extended temperature range up to +60 °C, this lithium battery for motorhomes and campers is ideal for year-round use.
The intelligent Smart-BMS monitors and controls all important parameters. Via the Bluetooth and WiFi app, you can always keep an eye on the state of charge and system data. Additionally, the CAN bus interface allows seamless integration into the existing onboard electronics.
For enhanced safety and efficiency, the battery is equipped with a Twin Balancer, which operates both passively and actively at 5 A. This supports uniform cell voltage, which positively affects service life and reliability. The integrated ON/OFF switch also facilitates handling.
Thanks to high discharge currents, the battery is also suitable for high-power applications such as inverters with up to 6000 W continuous power. An optional dual BMS further increases safety and enables redundant protection even with just one battery.
With up to 7000 cycles, the lithium battery Polar 320 Ah is a durable, low-maintenance and future-proof RV battery for use in motorhomes.
