280Ah lithium battery as a fully-fledged lead-acid battery replacement for your underseat battery in the Ducato, Transit, Sprinter or PSE mobile home

This 280Ah Lithium LiFePO4 battery is specially designed for mobile homes and for installation under the passenger seat. Many of the common motorhomes such as Fiat Ducato, Citroen Jumper or Peugeot require an extra flat lithium battery for installation under the passenger seat. Depending on the seat console, 1-2 batteries can be mounted one behind the other. With the new lithium-iron technology, you can replace your previous lead-gel or AGM battery quickly and easily for the first time.

Almost 300Ah capacity under the seat!

The ultra-light DeepC power battery can be used purely as a supply battery and can be loaded up to 200A continuously or 400A briefly. The significantly lower weight, the long operational reliability, the long service life and the long service life are decisive advantages compared to conventional batteries of old technology.

The lithium iron phosphate battery (LiFePO4) is the safest of the family of lithium ion battery types. It can withstand high currents, can be used universally and is lighter than lead, gel or AGM batteries. In addition, the latest lithium-iron technology offers a high degree of intrinsic safety, so that there is no risk of explosion even under the most extreme conditions. A 12.8V LiFePO4 battery consists of 4 individual cells connected in series, each with a nominal voltage of 3.2V. A built-in battery management system (BMS) also protects the battery cells from damage.

Advantages of our LiFePO4 DeepC-Power battery compared to lead batteries:

  • High discharge currents possible up to the specified capacity
  • Due to the up to 60% lower weight, more payload is possible
  • Due to the smaller space requirement, more capacity can be carried in the same space
  • Up to 10 times longer service life due to the high number of cycles of the LiFePO4 technology
  • Extremely fast charging of the cells possible
  • Complete discharge of the specified nominal capacity possible
  • The battery is protected by a battery management (BMS)
  • Charging in the mobile home is carried out using common lead or acid chargers with a final charging voltage of 14.6V
  • The battery is winterproof and does not have to be removed down to -20°C
  • Delivered fully charged, install and drive off
  • To use the battery, no changes to the motorhome or additional electronics are required
  • Due to the low self-discharge, a closed battery can be stored for up to 6 months without any problems
  • You can connect any number of batteries in parallel for more capacity

Battery Management System (BMS)

A battery management system monitors and controls the individual cells of a battery and protects them from damage

Important functions of a battery management system:

  • overload protection
  • deep discharge protection
  • overvoltage protection
  • Active cell balancing
  • Load monitoring and control
  • Temperature protection of the cells
  • BMS temperature protection
  • Automatic intelligent charging control from 0°C cell temperature
  • short circuit protection

Battery status display:Here we recommend installing a measurement shunt for precise determination of the state of charge and the consumption values. Select the appropriate shunt either with a display or with a Bluetooth connection and an APP on your tablet or mobile phone. We are happy to offer you the battery with a Victron Bluetooth measuring shunt in a bundle under item no. CSX12280-BMS200CSBS on.
