New 100Ah lithium battery for VW T6 models as a full lead-acid battery replacement for your underseat battery in the motorhome

This 100Ah Lithium LiFePO4 battery is specially designed for VW models to be installed under the passenger seat. Many of the common batteries are too big for this, not our new CSX12100-BMS200T6 lithium battery from CS-Batteries.

With the new lithium-iron technology, you can quickly and easily replace your previous lead, gel or AGM battery for the first time. A 100Ah lithium battery replaces a 200Ah lead battery.

The ultra-light DeepC power battery can be used purely as a supply battery and can be briefly loaded up to 400A. The significantly lower weight, the long operational reliability, the long service life and the long service life are decisive advantages over 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 standard 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
  • By default, the battery has a car pole adapter
  • No changes to the mobile home or additional electronics are required to use the battery
  • Due to the low self-discharge, a closed battery can be stored for up to 6 months without any problems
  • For more capacity, you can connect any number of batteries in parallel

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
