Description

New 200Ah lithium battery as a full replacement for lead-acid batteries for your boat, as a supply or electric drive battery!

The CS-Electronic DeepC-Power LiFePO4 battery is a rechargeable lithium iron phosphate battery with a built-in battery management system (BMS) specifically designed for boats or power drives. With the new lithium iron technology, you can easily and quickly replace your existing lead-acid, gel, or AGM battery for the first time.

The ultra-lightweight DeepC-Power battery can be used as a pure supply or drive battery and can handle short-term loads of up to 400A. Its significantly lower weight, long operational reliability, extended service life, and long lifespan are decisive advantages over conventional batteries using older technology.

Features:

  • High current resistant
  • Replaces a 12V / 400Ah lead-acid battery
  • Built-in BMS
  • Very low weight, only 21kg
  • Fast charging capable
  • NEW: Optimized software for parallel connection of large battery banks
  • NEW: "Alternator-Protected" - no additional electronics required to protect the alternator
  • NEW: Includes battery terminal adapter - ribbed & nickel-plated
  • NEW: Sealed housing, protection class IP67
  • High inherent safety; LiFePO4 cannot burn!
  • Usable in all situations
  • Temperature stable
  • Over 3000 cycles at 90% discharge
  • Lifespan up to 10-20 years
  • 100% maintenance-free
  • Environmentally friendly, no lead, no acid
  • Recyclable!

    Of the lithium-ion battery types, the lithium iron phosphate (LiFePO4) battery is the safest. It is highly current-capable, universally applicable, and lighter than lead-acid, gel, or AGM batteries. Furthermore, the latest lithium iron technology offers a high degree of inherent safety, eliminating the risk of explosion even under the most extreme conditions. A 12.8V LiFePO4 battery consists of four cells connected in series and two in parallel, each with a nominal voltage of 3.2V. An integrated battery management system (BMS) provides additional protection against damage to the battery cells. Advantages of our LiFePO4 DeepC-Power battery compared to lead-acid batteries:

    • High discharge currents possible up to the specified capacity.
    • The up to 60% lower weight allows for a higher payload.
    • The smaller footprint allows for more capacity to be carried in the same space.
    • Up to 10 times longer lifespan due to the high cycle count of LiFePO4 technology
    • Extremely fast charging of the cells is possible
    • Complete discharge of the specified nominal capacity is possible.
    • The battery is protected by a battery management system (BMS).
    • Charging in the boat is done via standard lead-acid or acid chargers with a final charging voltage of 14.6V.
    • The battery is winterproof and does not need to be removed down to -20°C.
    • Delivered fully charged, install and drive off
  • The battery comes standard with M8 screw terminals, which can optionally be equipped with our extra-light terminal adapters.
  • No modifications to the boat or auxiliary electronics are required to use the battery.
  • Due to its low self-discharge rate, a sealed battery can be stored without problems for up to 12 months.
  • For increased capacity, you can connect any number of batteries in parallel.
  • For higher voltage, you can connect up to 4 batteries (maximum 48V) in series.

  • Battery Management System (BMS)
    A battery management system monitors and controls the individual cells of a battery and protects them from damage.
    Key functions of a battery management system:

    • Overload protection
    • Deep discharge protection
    • Surge protection
    • Active cell balancing
    • Charging monitoring and control
    • Temperature protection of the cells
    • BMS temperature protection
    • Short-circuit protection
